Thank you so much! Hasn't gotten any better. I'm still wiring up my wideband before I put some miles on it to break in, then an actual dyno tune. Thank you again.

thats understandable. i appreciate your helping me.
From what I'm reading if the pcm were truly locked I wouldnt br able to live view sensor readings via hpt correct?
Were you able to look at that tunercat profile I posted and see anything that...
I'm getting the error message "http response failure" when trying to connect to the pcm to edit parameters, however we can read all the sensors in real time. Since the pcm is tuned with tunercat and...
Thanks! I'll see if my hptuner friend can see it
I admittedly have no idea what im looking at when it comes to tuning. Jeff created this for me (and has been very helpful in trying to resolve this) and im just trying to get input on how a base tune...
Hi, I figured out my problem with my 0411 PCM swap and i am now required to pump the throttle during start up in order to get it to fire and have to feather the throttle for a few seconds in order...
It lives. I didnt di anything. I just fired it up to move it out of the garage and it lived. I have a feeling this is just a fluke though. Drove it around the block and wants to die at idle. But...
The MAF wire is in fact getting hot, so it is still receiving power and at least functioning.
Correct. It will run, and will pretty well with the MAF unplugged. The PCM was supposed to have been flashed accordingly by Jeff. So I dont know if the MAF is actually bad, bad tune parameters or...
Update: MAF connector gets 12v with key on. Connector also has a good ground. Connector is showing 5v reference. There is continuity between reference line at connector and C2 31. So....bad MAF?...
I can get it to fire up with the MAF unplugged. So I dont think CMP/CPK sensors are bad or mispinned. I'll check voltage later tonight when it cools off. I'll also visually inspect the maf to see if...
Update: Unplugging the MAF works. MAF reference pin is in the correct spot. However i get no response from the sensor with key on engine off. Bad MAF? it was just working that morning.
Hi Dave,
Thanks for those schematics. I went over them and have noticed a few discrepancies between what they say and what my pinout sheet says. This is for a 7.4 vortec, maybe there are...
Gentlemen, first time poster. I attempted to use the search function but couldnt find anything that really helped me. I have a PCM that was programmed by Jeff at Lextech, and i am getting the crank...
