Oh, and one more question, should the trans revolutions per mile be the number of pulses per mile divided by the pulses per trans revolution? i.e.

114,105/40=2852.625 ??

Seems like this should...

I've done the math a couple of times now, and think these figures should generally be pretty good. Tires are 35" in diameter and using some tire calc sheets out there, the VSS pulses per mile comes...

I have an LS1/4L65e from a 2000 vette in my Jeep. I have been running a tune based on a 2002 Yukon for a while but have long thought it is not right. This weekend I opted to create a tune based on a...

I've been working on an issue and hope I might have it resovled. Basicallly, I have a spare PCM and had it programmed to stock with the base for my setup. I am running a LS1 from a 2000 vette and...

I confirmed that the seed is FFFF and not a something they entered. The only thing that is different is the PCM serial number. What I need know is some help on how to get HPTUners to read my...

Update on this issue. It looks like EFILive change the VCM serial number after it was flashed with the Tec2. The seed and key have not been changed, but the Serial Number of the VCM does not match...

Can you briefly explain what happens when you say "tuner locked"? I need to communicate to the tuner and/or EFILive what is happening so I can "undo" what they did. My problem is that I don't know...

I have a bit of an issue. I swapped out transmissions and needed to write a new calibration to my ECM. No initial problem. Had a local tuner guy help me out and was directed to load the ECM with a...

I have a 2000 PCM that I've loaded a couple of times and everything has worked great. I recently did a transmission swap and am having someone help me tune the new setup. He has started with a new...

I am close, but missing something with the speed calculation. I have a 40 tooth VSS on the back of the transmission (before the transfer case for a 4WD). I have 34x12.5x15 tires with a 4.10 gearing....

Sorry for this dumb question, figured it out. Used a 2000 Vette with auto stock tune as my starting point, now everything is working fine.

I have a LS1 from a 2000 Vette that had a manual transmission. I am switching to an automatic (4l65e) and pretty much have everything running now. The problem I am having is that I don't get any...

I am new to the tuning world and looking for a little help with the performance mode transmission tune. I have a 2000 LS1 from a Vette and am replacing the manual with a 4L65E. I have the...

I retract this post, sorry I did not read far enough in the FAQ. I found the stock tune sections and figure I can compare this to my current setup and note the differences. On a related note since I...

New to the forum and the software.

I have a LS1 from a 2000 Corvette in my Jeep. Right now, i have a manual transmission but am going to a 4L65E. I just got the HPTuners software and have a read...
