P0106, p0121, p0336 Im trying to tune a 02 Z28 A4 with unknown cam specs and just lid, LT's, duals, and stall. I put the car in OL SD and while driving it, the car sputters over 3k rpm. It threw some codes up...
P0106 - Manifold Absolute Pressure (MAP) System Performance
P0121 - TP Sensor Circuit Insufficient Activity
P0336 - Crankshaft Position (CKP) Sensor A Performance
Any help? I checked the "eng sen" fuse and it was good.
Thanks in advance

You've got some weird RPM spikes, and other little things like that, that just don't look quite right in the log. Are the sensors good? Does it throw those codes all the time?
It seems to be very rich for the most part, though that could likely be a spark issue. If you're saying that it sputters. However, there is a small group of cells in the AFR error histogram that are pretty close though. Is that something that you've already tuned? If you got it that close I would just continue doing that and it should work itself out.

the codes stay on and the rpm gauge jumps and then dies but the car is running. It idles fine but anything above 3k and it sputters and i saw some KR too. I need to smooth the table out some as well but i dont think thats it.
Edit: the group in the low rpm mid kpa is the idle and area that I already tuned somewhat.

I checked the sensor and wiring but it all looks good. I checked all grounds and battery cables. The + side battery cables are new and ground are good. I went ahead and put a washer on the mounting tab to see if that will help...gonna log right now.

I wouldn't worry about that little bit of KR at part throttle, just looks like a freak occurrence.
You're showing TCC lockup at 45mph in 4th in the tune, which might be a little bit low for a cammed car, but it doesn't seem to be happening all the time anyway? Probably from the crank sensor code.
