i thought i understood what i was getting myself into, but im at a loss of words of whats happening.
i replaced my 06 ls2 MAF meter with a 4" tube and ls7 sensor.
my problem is the car will not idle, ive gone as far as raising the idle to 1400 rpms just so it wont die,
idle surges from 400 - 2000 rpms. afr goes from 10.3 to 18.1. freakin insane and quite scary, the misfires are threw the roof.
ive tried doubling/tripling the maf table, tried using the powermaf, and tried scaling the stock ls7 table by % to my current ifr numbers around .86.
my tune is a basically a stock 06 tune scaled to 50%. but i kept the idle airflow numbers to stock. using the 60's with all the correct data. gregs dvd doesn't cover scaling. i just got in his new book. at a quick glance i didn't see any topic about scaling, but am gonna finish reading it tonight.
i think tommorow im gonna try a tune thats not 'scaled' , its late and the neighbors are pissed.
