I searched on this but I this subject but didn't find anything.

I just put a s4 motor in my s5 and have everything working correctly. But I get a CEL. When I step on the Gas a little under 1/4 of the way it goes out. Its not speed or rpm dependant. I tested it a bunch of times and its consistant. So, does the S5 have a CEL for TPS adjustment or is it something else?

Did you use the S5 MOP?

 

Oh sure

But the lines don't look like they have alot of oil in them. I went crazy with premix though for intial startup like 16oz to 5 gallons. The give the OMP time to prime.

 

OK, what else is a bit different between the cars/motors as far as the CEL is concerned?

The TPS assy, for sure, but you probably put the S5 TPS back on her too, eh?

I'm always getting boost sensor codes on mine, but it doesn't affect performance, could it be that?

 

S4 Intake With S5 TB. It seams like its directly proportional to the throttle input. The car idles at 1500 durring warmup and 750 after thermowax closes. My BAC is disconnected.

( I know the S5 is better but my LIM ports are seized on my s5 intake)

 

If it does it only when warming up, could be the O2 sensor...
