Questions about ECM
Help! I need you all to give me some advice.
Mechanic says I need to replace the ECM. I would like to know if I REALLY need to replace the ECM, or can I just chip it?
If I do need to replace the ECM, does anyone have any suggestions as to where I can find one? I feel like I've been all over town and all over the internet and I still can't locate this part.
I appreciate any suggestions/tips, etc.
Thanks all!

You didn't really explain why the mechanic said this.
Your words seem to indicate you think a "chip" will fix something, did you make changes to the engine or something?

Thanks for your reply.
By the term "chip" I meant replace the computer chip inside the ECM with an aftermarket computer chip. Turned out I needed the entire ECM.
Finally found the part and replaced it. Received a suggestion from a guy in a race shop that recommenced the Hypertech chips w/Thermomaster system. I might also replace the fan blade itself.
Obviously, I'm new to restoring cars, and I'd hoped that I could get some advice that could take my learning curve from here (_______________) to here (______).
Thanks,

Don't spend a lot of money on one of those generic "one size fits all" Hypertech chips. You can get the stuff to burn your own custom chips for like $65..

Get a PROM programmer, download the software, and learn to build your own programs with a little help from your friends at the DIY PROM board. It's so easy, even I can do it.
