To ad some data to back this up I uploaded 2 different tunes to this same combination and logged the throttle with both. They act very differently:
140271
The upper one is with OS 12593058.
The...
Sorry for starting a new post about this subject but the information within years seem to be spreaded across so many threads. And unfortunately those threads do not agree on this.
When using P59...
Thanks. I checked all my wiring twice and on the second time I finally cought the issue: "I had Cruise control ON" and "T/B 5V ref sensor 1" wires crossed. Now I have no trouble codes and the blade...

To my understanding this is the setup with these parts.
When all is connected, Throttle position (SAE) shows 16-19 %, throttle desired position shows 14 %. If I move the throttle blade by...
The battery charger has "supply"-mode which maintains 13.5V voltage. It works.
These DTC's are set:
P0120 Throttle pedal position sensor A circuit
P2135 Throttle pedal position sensor /switch...
EDIT/Update: I had two TAC wires crossed, so the problem was in my wiring. Now I have only 150% pedal problem...
I have a LS1 engine in engine stand and I have stripped original wiring harness and...
This is sorted for now: MAP sensor harness had +5V and MAP signal in wrong pins. I switched those and now MAP signal is available. The coasting problem (which I didn't mention earlier) got away by...
This leads me to think in my case at least the IAT side is wired correctly because I get reasonable readings. This MAP part number was given to Edelbrock when they sent the modified file for SCT...
The MAP sensor is Bosch 0 261 230 042. So it is a TMAP, right? I would like to make sure it's pinned correctly, can you guide me to the correct pinout?
Thanks. I will try to get info on this MAP sensor.
All MAP sensor related diagnostic codes are still functional and this doesn't throw a code. So the MAP must be functioning, I just cant get it to...
I'm having trouble with scanning. I can't get the correct MAP sensor to show on channels. I assume E-Force has 2 bar MAP but the only option I get when I add channels, is "intake manifold absolute...
Thanks, I copied the changes and I will test when I can.
The wideband was not attached to the HPtuners while I took the log file. There are cats, so the COT must stay.
I tried to find a way to modify cold idle AFR but realized the same cells are being used while cruising and there the AFR error is almost zero. After cold start in these same cells it is requiring a...
Some of the mystery got solved today. I put original injectors in and it started to behave as I wished. Now it responds to VE tuning by going richer where I want and leaner where I want.
So now I...
I changed MAP values to ones I looked from GM specs, I smoothed out the VE. I switched the MAF codes visibility.
Still exactly the same.
It starts well, runs well in open loop but as soon as it...
Thanks, my mistake with MAP and P0102/P0103, I copied them from an old tune (which was working fine though). However the mountain in the (not yet anyhow tuned) VE is not relevant since I'm on numbers...
Hi.
I made a 2 bar COS to this 12216125 -> 1252013 5.3 truck PCM and also enabled flexfuel.
Flexfuel sensor is showing the alcohol% and all seems to work fine if I command to open loop. Now...
Is anything going to be corrected in the EU site? I get to see the tune repository but no matter what I choose from there, there will be no matches. It's like the repository is empty.
This has been...
I already tuned myself to a mood that this car will have 4L70 transmission to communicate with the E67 and the T42 properly. I put in on side for few weeks and today I drove it to winter storage. To...
Yes, I tried with Envoy transmission settings and speedo settings. I disabled ISS sensors on transmission side and changed only final drive ratio in speedo settings. I checked today also that I have...
Thank you! Just to make sure: Am I on the right track with the VIN I have in the ECM since I dont have the ISS?
E67 + T42 4L60 seems to be quite rare combination.
And do I need to license the...
No, they are not programmed with same VIN. They are from two different cars. ECM is from 07 Envoy and I was under impression that TCM was from 07 Trailblazer SS. Unfortunately I havent got exact info...
Yes, this is 4L65 or 4L60 without input speed sensor.
I have wired the VSS to TCM as it was in Trailblazer wiring diagram. With GMPP setup it was wired to ECM.
I now have kind of 07 Envoy...
Now I have tested different variations of speedo calibration without success.
Trans output shaft speed shows zero all the time. But at the same time I can see the vehicle speed increasing when I...
