I'm pretty new to tuning and hex numbers exc. I've been experimenting with using Rom Editor to tune my Duaghter boarded SR20. I have quite a few bin files and I'm getting closer and closer to waht I want but cant seem to get my fuel and timing map right. I was wondering if anybody has any Bin files for 555cc injectors with a gt28rs and a maxima/RB20DET Maf? Or if anybody wants to post bin files for any other setup it might be helpful for everyone.this is my current tune, its running to rich and has trouble running when first started in the morning.
