Hey!
Got an 2002 Audi A4 1.8T with an ME7.5 ECU.
I've got it tuned by some guy over Facebook who really seems to know his stuff with the ME7 ECU's.
But we're having this weird problem, if i do a WOT run in 2nd gear it boosts up to 20PSI (ish) then drops down again to 15PSI as the revs increase.
The N75 DC is set as 95% fixed because i want to run as much boost as possible with my turbo (GTX28).
If i datalog the usual parameters i can see that at 4500RPM the ThrottlePlateAngel and the ThrottlePlateAngel Requesed drops from 100% to only 32% while the AccelPedalPosition is still at 100%!
Also i've got a intermittent starting problem when the car is semi-cold (couple of hours after its been driven). Where it dosent fire at all. If i reflash the ECU it fires straight up!
Any ideas?
Here's all the files i've got.

Don't have any link to him on here sorry.
The MAF should be scaled to 3 inch.
IAT was broken when I did the datalog. Replaced it but still not boosting properly.
I can post the. Bin file with the Kp. If you could take a look at it?

A link to his FB page would be fine. Post the files, we'll take a look. |

Turned out to be Boost By Gear that was the issue. The only reason he set DC to 95 was because I asked him to. Since the previous files didn't go as planned he didn't want to do fixed DC anymore.
I'm not sure if he wants me to post his name here..
At least I think he's an great guy that has put many hours into my file, so it's his first A4 so I don't blame him

70% cut in second. OP doesn't want to do pulls in 3rd due to speed limits, etc.
Now have request I'm asking for and all is well. AIT is fixed too. MAF is scaled.
