No X code. But it does say "Writer Verify: Failed"

I thought I took a picture of the screen, but must not have. I?ll check when I get back home this evening.

I am trying to delete the VATS in a 2005 LLY and am having trouble writing the file back to the ECM. I did not have any issues with downloading the file. Made my changes and went to write the file...

So, cutting to the chase, what are my options? I am also sending the current files to the original tuner, he says they have used this combination successfully in the past. Is there any OS I can...

To switch OS, it?s just as easy as finding one that I want on the repository, and programming it into my TCM, correct?

I cannot see it asking for TCC apply. It says OFF all the time. If the OS is for an ?11 Silverado, can an OS change possibly fix the issue? The stop light wire is hooked up correctly. Engine is...

The ISS has been disabled, and the TCC does not work properly. There are no transmission codes stored.

The brake circuit has two wires, one to the ECM and one to the TCM. The schematics I have found show both of them to be normally open. If I were running a BCM, the switch to it would be normally...

Ok, thanks. It has the ISS as a selectable parameter, even with that it is not compatible?

It has 13 pins. I?m pretty sure he said it was out of a 99-01 Silverado

I am working on a 67 Firebird that has had an LS3 and 4L60e swapped in to it. It came to me for some transmission shift point tuning. Upon first test drive, shift points were all very early and no...

Figured it out, the problem is mechanical. The overrun clutches rob 3-4 apply oil, not letting the 3-4 clutches apply. When I shifted it manually, the trans shifted fine. Sonnax makes a heavy duty...

I removed the wire from red 16 for the 4lo input and added a wire to blue 71 and a momentary switch to activate performance shifting. Tried lowering shift points and speeds, still no success in 4lo....

OK, tried the 4lo input, the speed sensor is located in the adapter between the t/case and transmission. The transmission shifted very quickly and was in 4th by 5 MPH. Tried hooking up a "tow/haul"...

Probably not, I am using the Jeep transfer case, so I will have to figure out what input it needs. Thanks, I'll look into that.

I have a 6.0 truck engine with cam and a 4L60e trans, shift kit and 2800 stall in a Jeep TJ. The trans shifts fine in 2wd, but in 4LO the trans will sometimes not upshift 1-2 and will never shift 2-3...

Hello everyone, I have a newbie question for you. I have a neighbor who has a 2001 6.0L with a 4L60e in a jeep wrangler. He had it programmed by another guy and is having some concerns when going...

Hello everyone, here is a beginner question because I don't know any better. I have a neighbor with a 2001 6.0L and a 4L60e in a Jeep, another tuner has been working on this and now I have the...
