Had a car tuned over the internet after some modifications and it has an erratic idle once it enters closed loop. Here is the mod list:
1300cc ID injectors
speed density conversion with visconti kit 'A'
process west intake manifold
TGV delete
perrin intercooler
blouch 3.0 turbo
perrin 3" turbo inlet
killer b header
invidia up pipe
cobb flex fuel kit
omni 4 bar map sensor
Take a look at the datalog included and I am curious if anyone has any ideas on what to try. Ive tried replacing both O2s, done a vacuum leak check, tried switching to a hybrid maf/map setup, I even tried a different throttle body since I happened to have a spare one. Curious what ideas people have.
The car runs great in open loop and if you unplug the front o2 sensor it continues to run great.
