As you may or may not know my Cupra has been running APR software for some time.

A couple of years back having previously ran a fairly modified Stg2 Mk1 Cupra R with REVO code. I decided after a year long hiatus of neutrality with a pretty much stock car to get back into modding the Mk2 Cupra which I've been tinkering with over the past 2 years since.

Due to certain reservations and stories at that time about the tuning foibles of the 2.0TFSI engine and my trepidation about any possible concerns.

I made the decision that I wanted to stay local to my tuner. I've had a great relationship with Awesome over many years of custom and I trust them to look after my car.

In a similar vain REVO have not let me down in the support stakes either, but it was a fair old trek to pop the car down to Daventry should I have got any problems. Though I know they have dealers locally, I didn't feel as comfortable with those companies as I do with Awesome or the folks at REVO direct.

Awesome are only a 20 minute drive away from home, and I feel quite fortunate to have a specialist in my backyard.

This was the primary reason why I went with APR code for the Cupra, not because of any perceived loyalty to one code over another, but simply my loyalty to Awesome as a customer and friend for my own selfish piece of mind.

REVO are also good friends and my support of their products has been un-waivered they have supported this site from the beginning as have Awesome. They are both invaluable supporters of SCN, so I'm very happy now to say I have the best of both worlds.

Short speech over I'll get on with what I want to say. :)


So today I was over at Awesome to have firstly a new Helix Clutch Kit fitted.

As you'd expect this was a big job, so I arrived at 8.30am so they could crack on with the clutch.

However not satisfied with just a clutch, I sneaked in an extra unplanned job for them.

I suggested while they had the gearbox in bits, it wouldn't be too much bother for them to chuck on some new THS FR3 engine mounts which I sourced from JKM another loyal SCN supporter.

This was made simpler with me bribing Awesome staff with a large tin of chocolates I pre-armed myself with. ;)

main.php


I then settled down for the duration, spending much of the day in the waiting room, making good use of my iPad. :)

Once the hard work was out of the way (thanks Alan :D) the car was back together all road tested, complete with new clutch and mounts it was time to do the dyno runs.

Out of fairness it was run using the APR code again, no alterations other than the new clutch and mounts. Still adapted to the car as it was last time it was run.

No fuel differences, same V Power I always get from the same Shell station that has a regular delivery on a very busy route. Very similar conditions in the workshop in terms of temperature. Figures came out as we expected comparable to the run we did the other week which in turn was comparable to the results from 12 months prior with a similar level of modification.

Car Stage 2+ mods : APR HPFP, APR Intercooler, APR 3" Downpipe and HiFlow CAT, Milltek CAT back resonated. Forge Twintake.

Todays back to back graph, APR (blue) then REVO (red)
main.php


Current SPS setup for the REVO code is Boost 9 Timing 6 Fuel 9 which is more than likely to change after I have consulted with REVO tomorrow at the Awesome open day event. It will then get dyno'd again in a few weeks at the SCN RR Day.

I'll need time to get a better feel for it and do some more logging to understand how its performing overall.

But from the point of view of driving the car tonight, it was mainly gentle as i'm bedding in the clutch. So I took a regular normal drive home, give it a bit of throttle where I could, but generally was fairly sedate just to get a feel for the changes.

The car instantly feels different, and different in a good way. The response to throttle is much more linear, with generally more torque in the usable power bands. Its not aggressive though as I pointed out I've not attempted to really give it too much loud pedal yet. One of the things that bugged me was a lumpy idle on the car, this appears to have gone or is greatly reduced with the new code.

The mid range increase displayed on the graph speaks for itself really.

Looking back I saw a dramatic increase in mid-range punch when I added the APR pump about 18 months ago. Since then not much changed with the APR code other than a slight refinement of the code late last year which nudged the figures up a little.

REVO's code has given the car another dramatic and noticeable kick right across the mid-range...quite impressive.

APR seemingly sell code on the premiss or emphasis of longevity, but not everyone needs to have the child reigns attached. My Cupra for example has clocked up 12500 miles in 3.5 years, hoping the engine and components will make it to 100,000 miles is way off in my mind.

I'm also not an animal with my car, it doesn't get thrashed to death, doesn't get drag-stripped. Its my toy, I enjoy it for the odd A/B-road blast and the occasional track day where i get to really stretch its legs. Serviced twice a year, I tend to log it fairly often and check for any fault codes. I'm no expert but I try to stay pretty hands on with it, in terms of keeping it running tip top.

As I said prior, I stuck with this code out of loyalty to Awesome and like Awesome have been stretching out hope that things would progress with APR development to Europe. But sadly that hasn't happened. Now Awesome have made the commercial decision to work with a company that values European and UK customers I feel I've got the very best of both worlds having great software that caters to my requirements and gives me the ability to choose its setup while still working with a great local tuner I firmly trust.

The new Helix clutch has a firmer feel to it, but is exceptionally smooth with a nice biting point. It's a little snatchy at the moment but thats to be expected. The flywheel chatters a bit at idle, but its really nothing of concern and you can only hear it if you turn both the radio and air con off.

The car does sound different though now when driving, whether thats down to the flywheel changing the sound in the gearbox I'm not sure, but I can only describe it as being more solid sounding if it makes sense. The gear selection could feel slack before and now you have to be very direct with the gearbox. It feels tight and new. This could fade in time as the clutch beds in.

I already had a dog-bone mount i sourced from Issam last year. Though this in itself tightened up the car, it caused a great deal of vibration in the cabin.

Due to this I had been somewhat reluctant to replace the other two main engine and gearbox mounts. My fear being it would create even further vibration inside the car.

I was completely wrong, adding the THS mounts has complimented the dog-bone mount and has reduced vibration in the cabin a lot. Furthermore on the road, the car handles better, its front end feels planted its grips better it doesn't crash over pot holes and generally drives much better than its ever done.

The engine mounts have been a revelation and I would really encourage anyone thinking of going for better mounts to consider the THS FR3 kit or another suitable kit such as the VW motorsport or VF engineering kits. Though the formers poly mounts may generate more vibration and be too harsh, I can't really comment on that. The THS kit has been produced with a higher durometer of rubber suited more to a fast road compliance, so it feels very acceptable...don't get me wrong you'll still feel some vibration into the cabin when pulling away but its nowhere near as bad as it was with just the dog-bone done.

So there you go, I've probably not covered every base, but its the start of new chapter with ZBOYD's Cupra.

So youve changed your mind about moving on then ?
That was a real interesting read.
I'm glad your interest has been rekindled on the 5th of all nights.

Wow Mark, thats an whooping increase, must be like driving a new car. As we speak my ecu is at Awesome having a reflash to Revo, i doubt i'll be disapointed. The clutch sounds great too. I'm fancying some engine mount upgrades too after that write up. Its great to fall back in love with a car.:)

Decided to keep it for a while, it just seems pointless to take on debt to buy a car that's really no different to this one. I thought about a few, but I really couldn't commit to something. So decided to invest some money into my house and keep hold of the Cupra for a few more years. Then I might look at something else.

Just refreshing it like this has made it feel like a new car again, got a Pioneer Sat Nav going in it soon too, so it'll be like a tech pack upgrade too. :)

Feels great on the road, really impressed with the engine mounts, transformed it more than I ever expected it too. I can't vouch that it will be the same effect on all, and i think solid poly mounts could be quite harsh. But overall it feels tight on the road, and really solidly planted, because the engine isn't waving all over the place pendulum like, and it just drives much better all round.

im reading a few threads where people are very impressed with REVO software over the APR.

Glad you enjoying it Mark, haven't seen the car in a while, looking forward to seeing it at the RR day :)

I think it just comes down to a lack of code development on APR's front, and that's their decision to make. Awesome had to get out as it was starting to hurt their business and thats not on because its a good outfit. So I'm happy they will feel the benefit in this market now. I'm still a firm fan of the APR hardware in the Cupra, these parts on my car have all added to the overall result today so its all good from my point of view.


It still needs a bit of cosmetic work doing, got a dent in the door from a football [:@] and I need to get the replacement jacking cover sprayed up for the one that fell off on the M60 12 months back. But I'm aiming to get it tarted up some more over winter. :)

Nice write up mate :) Fully loaded car [B)]

Scott


Cheers mate. :)

Great read. Thanks for sharing.:)

It must be great to have someone that good, that close.

Was the old clutch slipping...or did you just decided to change before you had to.

Really enjoyed reading that mate, nice write up.

Also, I whole heartedly agree with what you have put, couldn't of put it better myself.

Good stuff Mark. I think for Boost 9 you will need to increase your fuelling down to probably 7 or even 6 though - pretty sure thats what Kev told me one of the times I spoke to him, and the r/r backed this up - I changed the fuelling on the fly between runs, and the second run was spot on.

The engine mounts were something I was impressed with, much more so than say the Anti Roll Bars.

You guys are very lucky having the choice of places right on your doorstep with experts there in person to speak to. For us, sadly, up this way, we have a choice of take it or leave it which in our case is Custom Code or Revo. Star Performance are 100+ miles away, and they do GIAC although I believe they will soon be doing Revo alongside GIAC.

Anyway, the thing I would be real keen to hear is the flywheel. I know a lad with an S3 with a lightened flywheel and his opinion was that it ruined the car. Interesting that yours is so quiet. Did you get to weigh the difference between the OEM flywheel and new flywheel? Also, what state was your OEM flywheel in?

Cheers,

Al

Mark have you had an uprated Subframe mount aswell? or still got the standard one

Ive been going down to VW Racing alot to look at parts and Decided i wanted one of their solid Subframe mounts they said the two top mounts they sell wont really make a difference but the Subframe mount will


How much where they if you don't mind me asking

Good to see you again Rich, and Rob too. See you again in a few weeks, hopefully without the road closures that had us all on wild goose chases this afternoon. :p

Spoke to Kev today and adjusted fuelling down to 6. Its not been driven hard at the moment, I want to bed in the clutch gently and get used to the differences in the software.

Flywheel is fine, really its hardly noticeable. The gearbox sounds a little different, and its got a tiny bit of a diesel like sound to it when its idle with the clutch out. But other than that, it sounds fine.

Rich (Cupra R) sat in it today with the engine running, and felt the pedal firmness, and listened to it, I think he had the same conclusions...its a non issue.

Not that concerned about Flywheels that I got the scales out Al, so thats a no. :) But the Helix kit appears to be designed more as a fast road kit rather than a race clutch paddle setup.

OEM Clutch and Flywheel were in an average condition, it's a low mileage Cupra that hasn't been too punished.

OEM slipped occasionally at high rpms but was generally coping at 11500miles. However the clutch always felt wooly to me, basically as if it couldn't cope with the power transfer taking place.

With the Helix kit fitted it just feels rock solid, the gearbox performs better feels much tighter the biting point is strong and pedal has smooth travel and isn't over the top firmness or overly snatchy still acceptable as a daily driver.

It gets a bit achey when your stuck on a 5 mile tailback on the M60, but fortunately that doesn't affect me every day.

Drove over to Awesome again today for the REVO amnesty open day event, and gave it another good run out down the M60. Able to stretch its legs a bit more than before, and then due an accident diversion whipped down the M62 to Warrington then brought it back to Awesome via the back country lanes. Brilliant, smooth and the best its felt since day 0.

I was very impressed with the way the helix clutch felt mate. The initial noise subsided to an almost OE sound. The firmness of the pedal was a little less than my Sachs unit. Looking forward to the next RR day.

Impressive graph, Mark. It's interesting how you've lost the dip after peak torque with Revo. Can you feel that difference on the road?

Well impressed with it Dave, you can easily sense its got more to give in the mid-range than before. THe clutch alongside the mounts have all complimented the package and the software is the icing on the cake.

Mark have you had an uprated Subframe mount aswell? or still got the standard one

How much where they if you don't mind me asking

I already had the subframe (dog-bone) mount. It was a Density Line solid rubber mount I sourced from INA issam. The full THS kit includes the solid subframe mount too, but as I already had it, I just bought the engine and gearbox mounts.

Sourced them from JKM, £200 inc tax but delivery is a few quid more.

I couldn't tell you the labour involved, mine was in bits anyway for the clutch fitting, so it was just included in that large bill. :wtf: But I think the mounts could be fitted alone in 1-2 hours max to be honest.

I think the subframe mount does the primary work in preventing engine movement in a forward/backward direction that ultimately effects the wheelhop and preventing the exhaust from being wrenched about too much. However I think this generates a lot of cabin vibration too.

In the lateral plane when your throwing the car about, the engine rocks around and effects the handling. With all 3 mounts uprated, it handles better, the actual cabin vibration in mine lessened and its made the car feel more solid.

As I said earlier, full poly mounts would likely be quite harsh, the THS just use a firmer rubber block in the mounts and this is middle of road compromise.

Kool ive got an Neuspeed insert already so in cabin vibration is quite bad but i want it more solid so think il get the VW Racing one

They said it involves pressing the original mount out with a high pressure press

Yup the subframe needs removing from the car, and the mount is pressed out, and the new one fitted.

The car really should be geo'd too if the subframe is removed and replaced.
