I'm just learning how to tune my own obdI 94 z28. I recently did a t56 conversion and need what to tune out out the file. Also I recently did a cam swap so my BLMs were a bit off and I smoothed them out with VEmaster...anyone use that?? To be honest I don't know too much about what I am doing but would like to learn...(don't worry I like to do background research). I wanted to make sure that using VEmaster was fine since I'm running E85. Any other info is appreciated. thanks guys, Erik

 

could you just start with a manual tune? I did that to a friend's LT1 when he swapped (and had issues 'cos the RPM's kept dropping really fast during shifts), and it worked out fine. I basically copied all the important tables from the auto tune to the manual tune and flashed it in. It's been a LONG time since I messed with TunerCat and I did remember working with VEmaster and some other programs and did get my fueling corrected after a cam swap until I got a real tuner to readjust them on the dyno.

 

I did this back in 02'. At the time I didn't know how to tune so I bought a T56 computer from Madz28. They are the same thing as far as the physical computer itself but I ended up having to tap into one of the pins on the back of the computer to get the reverse lockout to work properly since the auto harness doesn't have a wire connected to that pin.

You could start by getting a copy of a stock manual bin 94 or 95 and going from there or maybe someone has a tune already with your cam specs. You might want to check on camaroz28.com also.

 

well I would start with a t56 tune and change it, however this one already has an extensive amount of changes done to it already as it had a dyno tune for E85 originally with a smaller cam and now some changes with the newer cam. Is there anyway to "turn" it into a manual tune. I'm not having too many issues just a SES light here and there and sometimes some minor rpm issues

 

was it dyno tuned with the auto or manual?

 

auto 4L60E with increased shift points, firmness, and TCC calibration

 

you are aware that your timing requirements are going to be different with the manual right?

 

nope sure didn't...I'd like to know more about that. lol
