Alright I bought tuner cat been messing with it and reading alotta stuff about it I still can't quite figure out shift point adjustments ... I went to table " normal shift up/down " and adjusted some stuff but its still revving to 6100/6200 to shift I know its too high cause It feels like it stops pulling up there as I don't have cams or anything ... does anyone know how to get it to shift at lower rpms ? Or what table to go to on the software ? Thanks

 

When it is shifting at those RPMS is that manually or with the shifter left in "D" ???

 

Left in "D"

I have a built transmission with trans-go shift kit Corvette servo Corvette pressure plate and small 2800 stall it has been doing it since I got it built

 

6,100 rpm on the tach or off the computer? Stock tachs can be a few hundred rpms off, reading higher than actual.

You'll need to adjust the "kickdown mode" tables.

 

6100 off the computer ...6300 on tach in car and kickdown mode will lower the RPMS in which it shifts? i just wanna get it so it doesnt feel like its dieing up top

 

okay sooo i changed the "kickdown mode" and put the tune on the car and turned the car on and bow it comes on and dies out almost immediately ALSO the fan comes on when i turn the key forward and stays on ONLY thing i changed was "kickdown mode" ... so when i went to put the stock alternate tune i saved before and now it says "Error PCM not detected" so does this mean i blew my PCM?

 

you turning the key on?

also a good idea to disable any antivirus software you have running also..

i thought the shift points were mph based in the normal mode up/down shift points table

 

Yeah the key is on also the fan starts running when turning the key to the "on" poisition ((ENGINE NOT RUNNING)) and i changed some of the mph settings made no difference at all

 

do you have the correct com port selected?

 

Just double checked yes it matches comm 3

 

try pulling your pcm fuse for a few seconds to see if reseting it will help..

 

You're tranny takes several hundred RPM to complete a shift. Especially in older transmissions. In the Performance or Kickdown tables, or both, drop the shift points at WOT like 500 RPM and see what it does. Upload the tune and try it out. If it needs more adjusting, do so accordingly. I took me awhile to undestand the whole tuning thing also. Good Luck.

And you may want to keep a spare PCM. They can fried very easily.

Always turn off any program you don't need running on the PC. And turn off anything on the car that may draw a charge from the battery. Also its a good idea to plug the laptop into a power outlet.

 

Kk will try tom. In am

 

You fried rom chips in the pcm if the fans are running non stop..

Might be able to pull the batt cables / fuse and reset it but doubtful.

Yeah fan is running non stop when key is turned on or ignition is turned on .. where do i buy a pcm ?

 

You dont need to buy a PCM, you need to fix the one you have, or have it fixed.

If you'd rather buy a spare and have that one fixed in the mean time, you can do that too, but dont think the PCM is junk.

At any rate, Ion at madtuner or Vince at Trifecta can take care of you.

 

So i can send this one out and get it fixed ?

 

Yes..

 

did you try to reflash it? could be just a bad upload
