Ollie, stop worrying until it's got stage 2...if it's still mucking around after some stage 2 tweaking....then it's time to worry....or time to post more logs

Yep think your right! Will just take it steady for now anyway. Will keep you posted

What does it hold to 6k Baz?

Between 12 & 13 psi at 6000rpm.

Don't think I'm going to get another remap just fit an AVC-R and lift the boost that way. Car's running rich anyway so a few more psi won't hurt it.

I did the logs in 3rd gear mate. Yeah tyres are Toyo T1-R 205/40/17. Why do you ask? lol

maybe a strange request but it was to check

and i agree your car seems to be really slow if the log has been done on a flat road and without too much front wind

on the first log i would say you have accelerated in 3rd gear from 39 to 88 mph in ~9s, for a k03s car it seems slow to me.

i don't think stage 2 would help you, the n75 duty cycle is at max to obtain a not so high boost, and i don't see how a new remap could change that

 

[Essex_Cupra]

Yeah ive checked it mate, looks fine. Was replaced a few months back under warranty after splitting like yours. Ive checked over and over for leaks but not found a sausage.
All was fine till i had the ko3's and milltek downpipe fitted, which made me think it was a fault with the turbo itself or the actuator is set incorrectly. Im just stuck for ideas now...

I had the ko3s fitted and the car went alot better!

But...

When i first fitted the Miltek d/p and race cat and centre section it seems to really pick up some pace..

And recently it seems to have slowed down alot not quite sure why!

How do you do these logs what do i need a laptop and?

Hi Jay, the log was taken going up hill which i thought would be better as there is more load on the engine. Im also a bit sceptical that the stage 2 remap will overcome the problem, but it needs to be done anyway. Do you have any thoughts on what could be the route cause?

Are there any other blocks anybody could suggest for me to log?

Thanks Ollie.

how do you log!!

Essex_Cupra:
Strangely enough my car does feel faster after fitting the ko3s and Milltek DP, it just the lack of boost im concerned about.

To do some logging you will need a laptop, the Vagcom software and a diagnostics cable which you get from http://www.ross-tech.com/

You can also get hold of the cables off Ebay but they are not genuine Vag-Com ones...

Had the revo stage 2 treatment today. Cant say ive noticed a difference, if anythin the car feels a bit slower now as it lost its initial kick at low revs.
Anyway the remap hasnt overcome my problem with low boost. Its still only peaking at around 18psi.

Can any vag boffins please help or suggest something for me to look for or to log on vag-com....

Thanks Ollie.

 

[Martyn]

Ollie, dont get hung up on peak boost, I doubt you'd notice a difference of a few psi anyway.

Re log the car using 2 blocks at a time...

020 and 114 together
002 and 115 together
115 and 118 together

Post the results in an excel file on here...

Oh yea...4th gear 2k - 7k please

Hi Martyn, I had the car run up on the rolling road after the remap and the results were 206bhp, 250lb/ft torque. So obviously theres something wrong somewhere lol. I will try and get some logs done tonight.

Thanks agen.

 

[Cupra_Wayne]

You sure you've got a K03s on there?!

 

[PhilW]

Sounds like decent figures for a k03 to me.

 

[-pseudonymous-]

Yeh im sure its a silenced ko3s, it has 8 impellors and is way louder than the other turbo even with a silencer! Havent got the part number to hand though.

Here are some more logs i did tonight after resetting the ecu after having the stage 2 update. Settings set at B6 T7 on the sps3.

Looks to me as though its hitting the requested boost and the turbo is no longer having to work flat out. The maf readings still seem a tad low though. What do you guys think?

Maybe i should wack the settings up a bit also as there is no timing pull?

Thanks Ollie.

 

[acidstrato]

maf figures look average for a k03 turbo

nah dont think you'd make that mistake. could be maf, all you can do now is unplug it and see if things improve or get hold of another to test

 

[acidstrato]

what dv do you have?

peak boost is still lower than my car with a k03, and higher up the range comparing yours against an old log of mine, yours is still lower at points

Hi mate, ive got a forge 007 with a yellow spring which i recently serviced. Ive also tried the leak back test and the piston stopped up when i kept my finger over the nipple. Maybe the maf is the kulprit but wouldnt it read a bit lower than that if it was faulty? It was reading around 147g/s's before having the ko3s fitted a couple of weeks ago.

 

[Martyn]

MAF is a suspect item, i'd replace the MAF then tweak the boost up a notch or too and see how she drives.

 

[-pseudonymous-]

Ive been concerned about the low maf readings for a while to be honest but they havent been excesively low so wasnt sure wheter it was worth changing. Is it likely the filter may be at fault, maybe a bit restrictive? Ive got a ram-air with the cold air feed mounted down in the bumper. I think i might just replace the maf anyway just to eliminate it from the list of possible kulprits lol

What do you think to the logs other than the low maf reading? I know the peak boost is still low but it seems to be better than before. Also will the car take time to adapt after the stage 2 remap?

Cheers

 

[Daz_gibbo]

Dont bother replacing the MAF, I did this when looking at 150g/s max on KO3s. And result = no increase, still 150 max. I am still baffled as to why, I had low figures on KO3 and it's transferred to KO3s. Still goes ok on the road so im not really bothered.

What map are you running? Requested still seems very low?

Ive always had lowish maf readings, with 3 different maf's. The trouble is its down on power according to the roalling road figures yesterday. And like you said the boost levels do seem low...

Im running the latest version of revo stage 2 on boost 6 timing 7. Maybe i should wack the boost settings up a notch or two as martyn suggested? Strange thing is i was seeing a higher requested on the ko3 with stage 1 revo on the same settings.

Seems as though the ecu is pulling back the boost for some reason. That couldnt be down to a dodgy turbo or actuator could it? Are there any other blocks on Vag-Com i can try logging?

Thanks Ollie.
