Re:having some trouble

From the pgmfi.com website:

Quote:

If you have a OBD0 ECU, chipping the ECU might not be such an easy option for you. Almost ALL 90-91 PM6, PM7, PR4 and PP5(with catalytic converter) ECUs had external EPROMs, and are easy to change the program on. Almost all 88-89 PG7, PM6, PM7 and 88-91 PM8 ECUs did not have an external EPROM. It is possible to chip these ECUs, but it requires considerably more work and is beyond the scope of this article. The following ECU is a PM7 that does not have an external ROM:

If you are luckier, the ECU you have will look more like this:

Unfortunately I don't know where to send you to get that info. However this paragraph does make it seem possible.

Re:having some trouble

Wait maybe I do, check out this website:

This guy seems to have done the same thing you're doing but the article doesn't really give details. I bet you can email him to see how he did it.
