First time logging in LCR

[jetsetjimbo]

Well after speaking to lots of you at Oulton I decided I needed VAG-COM.

Tried to do some logging tonight and got the figures below. I only did block 002 and group 005 (I know they shouldn't really be done at the same time now) also didn't do 115 and 118. Just wanted mass flow to start with...

25.85 6560 68.4 5.1 100.64 Enrich.


Does the above look ok? 160 g/s seems to be about normal for a stock 210 LCR? The throttle bit seems weird as it was mashed to the floor (4th gear 2000-6500rpm) run or is it always like that?

I got the below at the end of a second shorter blast:

6400 133.8 13.94 165.75

I am also trying to diagnose a bit of hesitancy which occurs intermittantly between 2-3k (in varying places) since I had a Revo trial but you might know it didn't do it tonight.

Would the 115 and 118 blocks be better for that?

Also are you guys mainly using registered versions? I'm using 409 with the lead I have but it dosen't seem to want to do the full fault code scan without complaing about not being a full version.

Any help / advice would be greatly appreciated. I couldn't decide if this should be in here or the Leon board.

 

[m0rk]

you need a throttle body alignment

 

[Feel]

MAF looks okay for a standard LCR. Don't know about the part throttle business (I don't log 002), but I would do a throttle body adapt just to be sure. There's instructions for doing this with vag-com on their site, or you can do the bonnet up thing I mentioned at Oulton.

Sometimes, at the end of a run when you lift off, you get a blip in the MAF reading, but I wouldn't discount a 165. For example, on mine, I usually see 210 and a little bit more, then occasionally see nearly 220 at the end of a run.

It's easier to see blips/dips if you graph it.

115/118 and 020 are the other blocks to look at, as well as 31 (air/fuel ratio) but that one doesn't mean much to me

 

[jetsetjimbo]

Cheers guys I'll give that a go.

Out of interest do need the fully paid up version of the software to do it that?

Also with the autoscan of the fault codes - should the shareware / unregistered version just do that?

Cheers

Sounds like you'll need to register to do some of that:

Indeed I was going to buy the ful offical vag-com interface but the distributor I was looking at has gone and the price of the basic thing seems to have gone up a fair bit in the last month!

Is the registration for the shareware automated? I.e can I do it over the weekend? Also can it be moved from machine to machine as many times as needed if the correct procedure is followed?

What happens if my HD dies and I can't get the de-activation code off the PC?

 

[Uwe@Ross-Tech]

There are a number of other distributors in the UK:
http://www.ross-tech.com/distributors.html#uk

And Ross-Tech ships to the UK as well.

There have been no pice increases, at least on our end.

No, the registration process is not automated. When registered to a particular PC (with a 3rd party "dumb" interface), it can be moved from machine to machine using the appropriate (see our FAQ page 5), but if you plan to change PC's often, you'll be much happier with a geniuine Ross-Tech interface with integrated dongle. Failed HDs will require a new code. This is generally not a problem if it doesn't happen too often and you're using the same PC.

[jetsetjimbo]

Thanks for that.

I agree I would be better off with the full thing but it's a little out of my reach at the moment. If I but the licence for use with the 3rd party lead at the moment and then upgrade to the full lot at a later date is the original licence refundable?

If so I assume the purchase would need to be made direct with Ross-tech rather than a UK distributor?

If I was to register this evening when could I expect the registration code? I was hoping to do some further logging this weekend...

Thanks

 

[Uwe@Ross-Tech]

Yes, registered users with 3rd party interfaces can get full credit for the cost of the license they already own if/when they decide to upgrade on of our interfaces. But in order to receive that credit, you'll have to use our interface upgrade program, which is available only directly through us.

Timing really depends. Its' only ~11:30am here at the moment, so if you hurry up, we can probably still get it done for you for the weekend, but I won't make you any iron-clad guarantees. And Monday is a holiday here...

Managed to scrounge an unused offical lead from a mate....

Been out for some more logging tonight....

This was done ~2k to 6.5k in 4th on a flat road.

Mass flow looks good. I'm not sure about the boost figures but the actual seems to be meeting the requested though.

N75 duty looks very low?

I did the bonet up throttle body reset but the 'operating condition' field in 005 stays on part throttle when the throttle is pinned. Is this limited by the ECU independantly to how far the pedel is physically depressed?

 

[Uwe@Ross-Tech]

Interesting. You've got practically no requested boost until ~3500 rpm. Now I don't know the 210 hp engine well at all (was never imported here), but this does not seem normal for a 1.8T with a stock turbo (even a K04). It seems to me it should be asking for boost much earlier than that. Perhaps someone with the same engine with an umolested ECU could confirm that...?

-Uwe-

 

[jetsetjimbo]

To be honest I'm not sure I was on full throttle until 3k ish but I was expecting to see it come on boost eariler.

I do have these sort of figures from other points in the log:

76.63 2760 87.2 1240 1310


so it will request more boost at sub 3k...

 

[DDX]

just make another log from 1500-7000 and full throttle
boost should come from 2250rpm... (and max boost around 3000rpm?)

 

[Uwe@Ross-Tech]

To be honest I'm not sure I was on full throttle until 3k ish

That would explain a lot regarding those numbers. I'm with DDX. Go do a run that's full throttle from 1500..

-Uwe-

 

[Feel]

I've never logged a standard LCR, but if your's is meeting requested, then I wouldn't worry about your N75 figures.

 

[jetsetjimbo]

Cool - will give it another go from 1500 rpm.

Going to do some more today to see if I can track down the cause of tge surging.

Also going to put the DV stpete gave me on there.

 

[Yak]

James,

Any update on this issue? I'm having similar issues inc late boost (after 3.5K)and have changed:

MAF, N75, Spark plugs, DV, Cleaned Throttle body and ran TBA, all with no joy.

I have a theory, but before I make myself sound stupid, how old is your LCR?
