Just some information- I tried the ROMs mentioned earlier in this thread (S203 and JDM 05 STi) which have the 400 g/sec limit. My v7 wouldn't start with them. I didn't really debug much, I just put the original af481 ROM back and it was fine.

yep, it won't work this way

in fact, any 05+ JDM ROM won't work properly on pre 05 cars because the neutral switch is inverted, and your AVCS won't work (there is a fix for this however)


I have 05 JDM RAC (A4TJ111C-RT) and I couldn't upgrade to 06 JDM rom either...


so is my understanding correct, that for JDM ROMS which are predefined for 400 g/s (like the case with mine) you can simply paste (recalbirate) this table into the air flow sensor scaling table and be done?

Bump to see how this was coming along. IS it still being developed, or are ppl who hit the 300g/s limit using other work arounds?

No, it is not being further developed right now - too time consuming considering everything else that is going. Do a search for halving airflow method (there's a post about it on Nasioc by MRF582 and others on here).

Hey guys,

sorry for bumping an nearly 8 year old thread. I guess due to the known reasons nobody has ever developed this any further?
