Default Speedometer Problem after Conversion

Ever since I have done my A4 to M6 swap my 98 Camaro has been off pretty crazy. What can I do to fix the problem? By the way I still have my stock 98 A4 Harness on the car. I am tuned with Hp tuners is there anything on there that can fix this problem.

Your numbers are off in the speedo calibration. go down load a tune from a six speed car and look at the speedo setting and compare them to yours. I had the same issue in my 2004 GTO.

Yea the Reluctor Wheels are different between the Auto and the T56.. the 4L60E is a 40 pulse per revolution, the T56 is a 17 pulse per revolution..

I just got done converting mine and I haven't had it tuned yet so it's off like crazy..lol

What is the pulse per mile for the T56? All I know is that it's a 17 Pulse per Revolution..

If you get anyone with HPtuners have them load up a stock M6 tune and look at the speedo calibration there, copy it and make adjustment for your rear gears. Thats how I did mine for my A4->M6 swap.
