Revo and Milltek

[gazbutmk5gti]

 Had the Revo installed by Prosport the other week, when Carl from Revo rang me to confirm the select switch, you buy them direct, he asked how the car had been set-up. I told him the settings had been set at values that Peter new would work, Carl said it should still have been set-up on the road using Vag-com, checking for timing pull etc. Now Peter at Prosport is a Subaru specialist so I think he is new to the VAG scene. Carl suggested paying a visit to Dave at ADS in Preston who is a bit more switched on to the VAG stuff so I did.

Peter had set the car as follows B6 F9 T5, and the car performed spot-on, really smooth, loads of grunt and pretty quick. 302bhp and 318ft/lbs I think.

So when I took the car to Dave I half expected him to increase the conservative settings, it turns out that there is an issue with 08 S3's, they are getting a mis-fire from cylinder 3 at the higher end of the rev-range that no-body is sure what is causing it. I hadn't experienced it but the logs showed it was there. Dave was out for around an hour trying different settings and settled on B4 T7 F9, the reduced boost settings didn't raise the fault. Dave had seen this issue before on 08 S3's, and when I spoke to Kev at Revo, they were aware of it and at a loss as to what is causing it. 07 cars don't suffer from it and all 8P S3's have the same ECU code, but Revo are working on it. . I was expecting a dramatic loss in performance levels, but to be honest I haven't really noticed any and the car feels crisper and more responsive, Dave puts this down to the timing being set as it should. It would be interesting to put in the rollers again and see if there is much difference in the top line figures as the car feels great on the road. Revo are working on the issue and have said they will let us know as soon as they sort it
Not sure if these issues affect 08 ED30's/Pirelli's, they think could be as simple as a different batch of knock sensors VAG are using, we'll see

Meanwhile back at the ranch , I got what I think is a bargain off e-bay, think somebody on here mentioned it, got a few month old cat-back Milltek for 249 quid, picked it up tonight and its like new. So I'm gonna pair it up with a new down-pipe and sports cat on Friday and have the settings tweaked to suit. We all know how well these secondhand Millteks peform don't we, hey Ben


Thanx for reading my ramble

What CFs did he see with T7 on VCDS as I would have thought it would be well over the revo suggested  -3 at these tempuratures even using 99 RON fuel.

My Ed30 threw a Cyl3 Misfire at WOT high revs, so they knocked the boost back a little and it no longer appears.
Does seem to be the same error.

Sounds the same issue, Kev at Revo suggested it has alot to do with how you drive, If you use WOT and rev the car up to redline all the time you will get the fault. I tend to use the stomping mid-range and not rev the car so much so this could be why I hadn't noticed the fault

CF's? correction factors?, not sure pal will ask, this side of things is all new to me. Not even had time to load the software for the selectplus switch I've bin so busy. Could you explain

[CocoPops]

Ah, see I came from a Honda S2k where you have to go to the redline
So hence my approach is to ensure she's warmed up and then "use the revs"

When adjusting the settings for best/optimal performance you should log the 020 block using VCDS.

This should tell you if your ecu is pulling back timing and how much. If you are you will see a negative angle delay aka correction factor(CF). Revo suggest you optimally try to keep the value under -3 for all cylinders.

Here is a graphic of such a logging from a guy using APR with problems.



For more detailed info you should read the pdf that came with your select plus.

Cheers for that, will have a read when I get chance.
 Dave tried lots of settings and B4 T7 F9 gave no faults and everything else was in tolerance as far as I know, will have another chat on Friday

Hmm, seems similar to what I was getting with mine. No3 cylinder was getting -4.5 at 1520 revs up to -9 between 1760 and 2720 and then -8.3 up to 5400 and then dropping back to -5.3 up to 6400 revs. Now I'm getting less than -3 throughout all cylinders and the engine purrs like a kitten.

Remember back to the Awesome RR day and the logs I did - CF's was what we looked at to make sure they were all running within their limits and no pulling back to much - your and bens were fine.

just always remember changing one value can have an effect on others, outside temperature always play a part - I have recently put my timing back upto 6 from 5 now its a little cooler, will let it settle and do some logs to check all is well

Good practive for anyone with a remapped car to do some logging every so often even if they dont have the option to alter settings.
