Flashing pcm with stock bin

[Nu 2ner]

TunerPro RT $EE XDF definition for bin adjustments and ADX for data logging. Only thing it won't do is flash, so you need TunerCat WInFlash, it's only $20. You do need an ALDL cable.

So I only need WinFlash and not TunerCAt? Or do I need the whole TunerCat Program and the $EE twenty dollar definition file? Basically just curious of if I have to purchase their $EE file or not. It's not much but if I don't need it in conjunction with using TunerPro RT, I don't want to buy it. If I do need it I will buy it. Sorry for my confusion, I am simply trying to flash my pcm at this point without having to wait until Mon. or Tues to get a file from TunerCat!

Just WinFlash.

Ok I have WinFlash from TunerCat, I'm sure you have to go through this a lot so I'm sorry in advance for my ignorance! Can you please walk me through what I need to do to flash my pcm? I have the TunerPro opened, loaded my stock bin file, and also have loaded the xdf file and adx file I got from this site. I'm not ready to try to change anything as far as tuning, just want to flash stock program for 94 z28 on 95 caprice pcm. Thank you for helping me, sorry for the bother.

I might have figured it out, I can just load my stock bin file onto winflash and program directly from there, correct? I loaded the bin file and hit program and it popped up the screen about shutting off screen saver, blah blah blah. So I'm ready to go now?

Right!

TunerPro will do the adjustments to bin and data log. TunerCat Winflash will do the read and flash.

There are precations. Full charge battery on car, full charge on laptop. Battery chargers on either can cause issues. Make sure everything on car is off, screen saver or ? Does not become active during flash.

About the hardest part of Winflash is setting up com port. Have to look in your device manager to see what Com port USB went to? Get that Com Port and enter it in WInFlash.

I used the bin file I had once, car wouldn't start. Used the bin file I got off of this old site for a BKNF pcm, car wouldn't start. Both times the program had no trouble running through programming, said was complete, turned off ign. unhooked cable, no start? Do I need to program my VIN into it for it to work correctly? If so how do I determine the model number, I have to have that in order to changethe VIN in Winflash.

No I've run the wrong VIN... maybe the PCM you put in was bad? I've put VIN from Chevy truck that LT1 was in and worked... but you have a 94 Z28 so put the correct VIN in.

You have the stock bin right?

Batt in car and laptop charged?

Turn key on, no start, does CEL come on, blink and stay on? If so flash was good!

Why did you need a new PCM? Now you still have issues? Is it a VATS issue? Turn off VATS in TunerPro, save bin, always save bin after changes with new name, TP recalculates Checksum, and reflash and try to start.
