400 SBC converted to TBI

Post by wtjoker »

I am running a 400 SBC using a 1227747 ECM. The engine has full headers, a high rise intake, and a TBI from a 350. I originally had the ecm programmed thinking I was going to use a 454 TBI on it (knock sensor is disabled due to false readings on 400sbc), but I was unable to find one. It's running pretty smooth, but I was wondering what adjustments I may make for the 350 TBI (ie. IAC)? Transmission is a 3 speed 350btw. I have attached a link to the bin file I read from my chip if this helps. Thanks! Any other tweaks suggestions would be appreciated. http://www.markscoolsite.com/backup400.bin

Not sure I can be much help, but you should post the xdf with the bin file.
