Just drove around town died a few times and didn't wanna start
Cruised on the hwy, Come to a stop push the clutch in goes dead
Not seeing the lean issue anymore
hunt is from 900 to 1500
Just popped a p0341 camshaft sensor performance and p0172 system too rich

while we're on the tuning subject, on my old tvs tune for the idc 1000s car idled like butter right at 950rpms. did some tuning with joe and found out his tuner cable and interface took a **** while tuning a car on the race track that hit the wall with his stuff in it doing some data logs. Now my car is idling about 1350rpms, when everything in the tune looks to be spot on. Also my car isnt commanding PE until 7500 rpms and even when it does its staying around 1.05 lambda. Has anyone that has tuned a turbo setup seen an issue where the scip sensor which is a one bar sensor is now seeing boost in my hahn manifold? and the pcm is possibly getting freaked out by that? I know some guys throw a voltage code related to the scip sensor but im pretty stumped right now. My lambda error % was like 27% lol. Need to work the MAF as well

timing was going negative a bit at idle, didn't really have much of a chance to get that straightened out as the car would barely run after a shut and cool down cycle.
MAf was rescaled
as for idle trims it was -12.5 which of course was not the finished product persay, but we got stuck on the other issue before I got to clean that up more.
I"ve run into a similar issue before as state with infe's car, but his was more random, and it would go back to normal if you blipped the throttle. Still waiting for his motor to come back to the machine shop to clear that up

kpa, rpm, etc. what does it show as commanded afr when wot? and as for the scip I've run with and without it and never noticed an issue, just turned the codes off for it so it wouldn't through a cel

Pe delays are all correct. That's to know about the scip sensor was just curious if it tied into everything. Commanded lambda didn't change to .81 until 7500 rpms and sometimes doesn't change at all. And by the time it does, the actual doesn't change because I only have till 8200 to see it change. Gonna try some advice and 0 out tps and rpm, an lower the kpa settings to see if it engages where it should. Because the car is also idling at 1350 with spot on trims and no vacuum leaks anywhere. Wondering if the throttle body is starting to fail who knows.
