ya that would be a silly oversight if your param file wasnt setup right. Like I said, my car behaved the same way when I tried to take around the block before it was tuned. As soon as it got past 10% is bucked and tried to die. I could easy on the throttle and get it to rev just fine, but nothing over like 25% (tps transition in utec)
will it drive fine without the wastegate springs?

Pretty sure mine acted like that bc the AFR was way off. It would run just fine without the blower belt on (thats why i suggested try with no WG spring). JT at PF put it on the dyno and got it to run after 1 pull. But that was all before I knew anything about the UTEC, so I dont really know what the problem was. I was too scared to really touch any of the settings back then.
Any way to post screen shots of your param files.

hmm with a log you should be able to grab AFR.
Your 0% should be around -10 and your 10% column should start at about 60 at 250 rpms and go up to about 100 by redline. and then ~+10 for each column to the right. thats what you seem to have.
too bad you can buck when its too lean or too rich. without a good log, you are shooting blind
also, what is ckp?

we both know what the ckp does. if there is an erratic signal coming from the ckp then there will be an erratic action due to the erratic reading. just a thought. ive encountered it a few times where the ckp is fine during idle or during light load, but the minute you get into load, it freaks out. as stated, ive encountered it before and there was no code being thrown. last car that it happened on was our customer quang with the sc fx35. no code was thrown for the ckp but it bucked and acted all crazy when under load. drove fine, but under load it was bucking and bogging. just a thought as stated.

Great post and lots of nice details in here. Your projects are always facinating and innotvative!
If it helps any. I had an issue with my CKP after installing a new clutch and flywheel. Under some conditions (usually when i'm about to stall going in reverse) the flywheel would slightly hit the sensor and would throw my car into limp mode (I didn't hear or feel it hitting, just the car going into limp). It's not 100% reproducable but the tech pulled out the transmission and put it back with a new sensor and all is fine now. Something was not lined up correctly initially.
Prior to taking my car back to the tech I did have a few dyno runs and my car would stop making power at 5250rpm. This is after clearing the SES light. After the new CKP and reinstalled clutch everything was back to normal. HTH.

Great thread. O.P, hope you get your issue resolved quickly. I'd love to have you come down for a photoshoot with you and Phunk.
We (ChicagoZ) are supposed to do a cruise up to Madison next month. Hopefully you can have her running by then and come out. I'd love to see her in action
