Port mod for flash II

Does anybody have instructions to Port modThe Flash 2 system. This was one of those things I never got around to until it was too late. If the information is lost, what would be the best way to try to find one? RIP BobR.

Re: Port mod for flash II

There was never any public port mod directions. It is a very involved process from the experience I just had trying to replace the ECM portion of my EBL Flash w/ Port Mod when I thought the ECM had failed. I was unable to successfully perform this process even with a ECM with the changes made right in front of me. There are several printed circuits that are terminated, soldered locations that are hard to reach, the actual little board that is needed in the first place also has to be properly soldered in with its jumpers. Which, if you don't have that board, you are dead in the water regardless.
