try tunercat's winflash tool to see if that works instead. it's not free but he has a 30 day demo available
I tried. Its the pcm i have to change. It does connect but when it has to erase the old bin on the pcm to upload the new one it gives error both with winflash and eehack
Can you read the PCM. How is your voltage. If it is tool low you can`t erase the chip.
Its a 1994 z28. When i went to flash it i had another car started with boosters cable hooked to the battery, while i had my car on ON i did not measure the voltage but the in car gauge was showing around 12. I may have to measure it with my volt meter but i think its enough to be a le to erase the old bin and upload the new one
PS i have a OTC 4000 scanner but i would have to hook it up, read the voltage then remove it, and put the aldk cable for the laptop

Scanner showed 12,2 V with fans off and a booster car hooked to my z28 to ensure good battery voltage. Used both eehack and winflash, could read the pcm with both. Stability test okk 15 out of 15. But when i go to flash the ocm at the oart it has to erase the file to upload the new one it gives me error. Cable is red devil
