I bought a 27C256 chip that was preprogrammed for the PK2 ECU.
I removed my ECU and soldered in an IC socket. Then, I inserted the chip. Unfortunately, I had earlier removed the sticker on the back of the chip, and erased it via exposing it to UV light (the sun).
The car didn't rev past about 3300 rpm.
I thought it was the soldering job, so I had it professionally redone. Didn't fix it.
I thought it was the chip, so I returned it and got another. Didn't solve the problem, still.
Now I don't know what the problem is.
I have a new "good" chip, and there's no opens or shorts in the soldering, but I still can't rev past 3300rpm.......
What else could have blown in the process? Is it the ECU itself? Is it a relay, or a fuse?
Thanks for all the help.
And thanks for understanding why I posted it here...
