did you use a file taken off of the current pcm to apply the 2 bar?
It doesn't have to be perfect, it just needs to be done in two weeks...

yes, then i did a full rewrite and then the car wont crank and i get that error when i try to flash it?Originally Posted by foff667
did the full rewrite fail or something?

no it took the full rewrite, but before i did that i accidently did a normal write with the 2 bar os. Then i did the full rewrite cause i realized what i had done. Now it wont let me do anything? Is the computer fried?
normal write with the 2 bar os killed the pcm. Thats your answer
98's don't hav ethe checks that the 99+ computers do...you need to do the full write FIRST otherwise you'll fry the computer.

Thanks foff. I guess i screwed up. Didnt know it would hurt it. Damn 98s! Can i get another computer and flash the 2 bar with that vin to the new computer?
98's are fine...my last LS1 fbody was a 98 and I probably flashed it 100x without incident...the problem here is that the 98's dont do as many checks operating system wise as the 99+ cars do so if you do a partial write of any OTHER os other then something based off of that vehicles you can easily fry your pcm. Once the 2 bar is in its in & you just do partials after that initial write...his mistake was trying to do a partial write of a 2 bar OS to the stock 1 bar OS...the 98 pcm thinks everything is fine plops it in but by then the pcm is fried. Theres a difference between being scared & being CAREFUL.Originally Posted by gold98Z28

being scared to fry it is not the reason for not wanting to start with it. i know the lack of RAM will not allow RTT and several tables are missing that later ones have from what i read here. plus i can opt for the year model since my dad has a 02 35th car. i think it will be better in the long run not to use credits on the 98 till i repin and replace with a newer pcm

personally I would just do a vin locked license on it & be done with it in your case rather then going through the trouble of repinning but thats just me.

can i use the OS with the two bar applied of the computer i fried and write the new 98 computer with it? Or have i lost the 2 credits for the 2 bar upgrade? Thanks
