Hey guys, I've put a 5.0l in my xf falcon. I used a NF fairlane as the donor car.
It was obviously a auto with smart lock so I've got a T.I performance j3 chip with a manual bin and smart lock turned off. The engine I now in and runs but there is a few issues.
The main issue is that the thing wont rev over about 3500 to 3800 rpm.
sounds like a rev limmeter, It don't matter if you hold your foot flat to the floor in neutral the thin wont rev.
I've put a light on it and at this rev point the timing drops back to near TDC.
I've now tried every single V8 bin that is available on the T.I Web site and it's all the same.
I've tried 4 Different MAF sensors, Some make it idle and throttle response better but the rev limit style issue is still there on all of them.
I've also tried 4 different ECU's EL and EF and still the same thing.
I'm a bit stumped at this stage has any one got any ideas?.
