Hello all. I have a similar problem and was going to start my own thread, but found this one.

A family member has a 1937 Chevy with a 2005 Envoy/Trailblazer 5.3 V8 and 4L60 trans combo for the...

My tuning knowledge is limited and I don't know how to even tell which channel or RPM it is logging. I do know, using the compare function, that the tach output currently is set to Crank type and a...

VSS status: Yes, it was only a concern as a possible cause of cruise control operation. The VSS is a stock sensor and giving speed to the TCM. The ECM and TCM are talking. I know this because the ECM...

I got it working!

blindsquirrel, thank you so much for your time and responses!

My friend, I think you're right. And we came to that conclusion at roughly the same time. Two parts to this post. One, I shot a video of my issue:

Two, while doing...

I isolated it. It was literally down to a wire only coming out of C1 pin 32 and was still seeing voltage anytime the ignition was on (+10v pedal rest, +12v from pedal switch when pedal depressed). No...

OK, I've done a lot of digging and have one issue left. But first, to clear some previous questions up:
The VSS is a stock sensor. It has a yellow wire and a purple wire leading to pins 16 and 41 of...

Thanks again for your time replying. I'm going to try and do more digging on Thursday.

Thanks again. You know your stuff. I'll take what you have said and do some digging in the system. One last question (assumption? haha): The transmission shifts perfectly. Wouldn't the TCM (T42) need...

blindsquirrel,

Thank you for your reply.
1) Yes, the vehicle speed sensor works. I say that because it has a dakota digital VHX control box that is taking a single wire input (I assume pulse)...

Hello all. A family member has a 1937 Chevy with a engine and transmission from a 2005 GMC Envoy 5.3 swapped in (E40 ECM). The car is 2 wheel drive. We want the ECM to see the vehicle?s speed. When I...

Bill,

I expected that response from you.

What exactly did I license then?
Under License Information -> Details -> it says: 86YMRKM0520728E6
Under VCM Info Log file I see: 86YKUCM0428919GL...

Apology accepted.

Let's get down to it here. I've lost my credits? I've definitely licensed something I won't/can't use.

5FDP,

Thanks for chiming in. Sounds like I should've acquired an E40 ECU from a GXP (the V8 5.3 model) instead of the V6. Dang.

Bill,

I don't like your tone with the "I'll just leave this here". I'm the customer, you're the service provider. Don't be condescending. Be polite. Be professional.

It only asked to use 2 credits? There is a video (like an advertisement) that you guys send in your package (on the USB drive) that shows a guy downloading from the repository and flashing onto the...

Hi Bill.

I downloaded it from the HP Tuners website (Tune Repository). https://www.hptuners.com/my-account/tunerepository/?

All,

New guy here.

I ordered the MPVI2 with two credits (~$400) the other week. Yesterday I got around to using it and have ran into an issue.

I?m swapping a 2006 Pontiac Grand Prix GXP 5.3...
