So no matter what I tried, i just couldn't get the 6L pcm to control the alternator. I installed the original pcm from the truck and now it's working fine. For whatever reason, the pcm that used to...

The LQ4 pcm is a 2004 model. My pickup is an 05

I've played with both those alternator settings and neither of them seem to make a difference. In fact if I mirror the settings that the 4.8L pcm used, I get a "battery not charging" indication on...

My alternator isnt charging very well. battery and alternator are new, im only getting about 2 volt signal from the PCM to the two pin connector (on both the grey and brown wires) I cant find any...

Or maybe it is reading correct and you have a steam pocket in the system? Try burping the rad

I used a sensor for a 98 camaro on my L33 swap. It's a 3 wire sensor so I could run to the stock gauge in my dash. Your sensor may be faulty, or wired backwards maybe

Well, maybe this thread will help some other poor bastard out in the future when they look at my log files with swapped banks 😂.

wayyyy better now that the wiring is swapped! This is just idling up to temp in my driveway. Thanks everyone for the assistance !

Thankyou. Wish I could test it out on the road now but they sanded and salted everything now and the truck has fresh paint. She will have to hibernate till may now

I did contact them, but I was in a rush to tune my truck so I purchased more credits right away and got it to work the second time. support ticket number was 155941.

very strange..but i'll go with it. Thank you very much!

Right on! I'll fix that up. So one sensor measures how rich and the other measures how lean, is that correct ? And then adjusts accordingly?
I would have thought they both had the same job. I'm...

Quick question if anyone is still checking in on me....i found that I had my bank 1 sensor 1 pinned to the bank 2 sensor 1 spot on the pcm, and vice versa....would this have been my culprit?

Yeah they are disabled in those logs. Only way I could get the truck back home yesterday was to keep resetting the LTFT in the scanner, so I just stopped and programmed them out instead.

I got burned like this last weekend to. was plugged into my truck with mpvi2, used 2 credits on it, then went to write to it and it said unlicenced vehicle. bought two more and did it again and it...

I threw some new o2 sensors in it, made two logs right when i fire it up. didnt seem to help my situation lol. sprayed brake clean all over the intake while it was running to try find a...

Thank you all for the helpful tips.

what other data would be helpful to log? sorry im very new to this stuff.

Thanks. I do have a wideband in it. its reading through the ac pressure sensor. Ive never messed with tunes before..all I can go on is that the truck ran fantastic on a stock tune, then poorly on...

Good to know hes a memeber here. Last time I drove the truck was 2 years ago with just a stock tune with vats turned off, and it ran excellent

Good morning, I had sent this PCM away for a mail order tune a couple years ago and finally tried to drive the truck today. It is NOT happy. Can hardly even get it out of my driveway. It was done...

70362 is my ticket number

Thanks for the reply. I will have a look in the junk mail

Good day, I purchased a used MPVI Pro tuner and I have been trying to contact HP tuners all week via their support email to get set up with an account. Is there any other way to go about setting...
