How do you change the revlimiter using Tunercat??? Thanks

Look under "Constants", there are two "Fuel Cut-Off RPM", and two "Fuel Restore RPM". Those are the rev limiters. Top speed limiters (If your car did not come with speed rated tires originally, they will be like 118 MPH) should be right there also. Called "Fuel Cut-Off MPH, and "Fuel Restore MPH".

Good luck, Ed

Do you mean the DFCO options? I can't get the rpm past 6375I haven't got my cable yet and I am trying to figure a few things out first. Thanks Ed.

Nope. Unless he has changed it since, ver 2.07 (which I have) you pull up, or open, your file, then at the top you click on "Tables", when that box drops down click on "Constants". The things I told you to look for should be right there in that list.

Good luck, Ed

It might be because I just have the file that came with the program. I have a ECM Constant table, but I can't find that option in it. Thanks.

Tunercat comes with the definition file and binary file, as an example, for a 90 model, or so, throttle body truck. They have no rev limiter. You will have to buy an "EE" definition file to open a '94/'95 LT1 calibration. Then read your PCM, to have the file to open. Lots more stuff in an LT1 calibration than a throttle body truck cal.

I bought the $EE file, my AKM cable should be here in the morning, hopefully I won't screw this up. Thanks again Ed.
