So I posted this in a different thread I had started that began as a No start first start thread. It has progressed to a run ability Issue now that I have got it running. So I started this thread as it is now a new problem.
A quick 411 about what I'm working with:
2003 S10 w/p59 4.3l ECU
2012 5.3l Block with 12k miles
Lingenfelter converter box
98 5.7 heads with yellow springs
2004 Z06 Cam and new lifters
2004 Z06 MAF
4"CAI
LS1 Intake and injectors
All new Corvette accessories drive (including alternator and PS pump)
CPW Wiring harness
92mm TB
Stainless Works Longtube headers
I have swapped all 2004 Z06 Vette parameters over to ecm and selected Platform Type Y which is what the corvette uses. I got it started by choosing the Y platform. It seemed to be missing. I got a P0300 code.I did a crank relearn once I got it running. The code went away. I shut it off for 30 sec. and restarted and after a min the code came back. It still felt like it wasn't running on all cylinders. I did a individual injector cut out in VCM Scanner and #1-7 have a definite rpm drop. #8 has no change at all. not even a hiccup. So before I pulled the injector and put it in a different hole to eliminate the injector itself, I warmed up the motor again and IF temp gunned the header tubes. I also did the carb cleaner squirt test. (fool proof)LOL and I show all are firing except #1!! WTF?!?! So I pulled the injector harness plug on #1 and performed the cut out test again. Guess what? #1 cuts out! (remember its unplugged) #8 still does nothing. So I checked the schematics for the injectors thinking maybe CPW made an honest mistake and wired it wrong. NOPE all is wired as the schematics show it should be. Now what? Why is my #1 acting like its #8? Is there a setting in HPT that I may have missed to get the ECU to know what Injector is which? I believe if I can figure this out that will fix my P0300 code as well as smooth out the idle. Obviously its running on 7 not 8 holes.
Here is my current tune file.
Thanx in advance for any education you may offer.
