Hello all. Thought I'd pose this question regarding LT1 edit since the people at LT1 edit didn't know how to address this.

When I use LT1 edit on my 1996 Lingenfelter LT1 car to correct the speedo, it never calibrates it correctly. I enter the gear ration and all and upload the new program. Starts up and runs and everything, but for some reason...when I run it on the smog dyno it's a good 5 to 10 MPH off depending on the speed (15mph to around 70 mph).

What gives? Is it some sort of programming glitch in LT1 edit?

Any help would be appreciated.

Thanks.

It's a problem with Tunercat software too.
I made a spreadsheet to maually calculate the values.

It's accurate to 1mph at 100 mph. I verify my settings via GPS so my numbers are corect every time.

PM me and I can email it to you.
