ECU question - 1992 Mazda B2200 Sport (fuel injected)

Though I have read on a few forums that people have replaced their ECU... I have not read that anyone suggests performing specific tests BEFORE installing the ECU.

The reason I am concerned is that I received back an ECU that stated that the solenoids/relays must have a resistance value of no less than 20 ohms or it could damage the ECU.

I called Mazda about this and they seemed clueless, but... they said that they do perform tests on the connector to see if there are any shorts, etc. prior to installing the ECU (so I assume this is probably what it is).

Mazda also said that they MUST reprogram the ECU after it is reinstalled for it to function properly.

No where have I read that this is necessary.

Mazda said that they charge $99 to 'reprogram' the ECU and if they have to diagnose it after that it would be an additional $99.

Does this seem correct or are they doing things that are unnecessary?

Any advice would be greatly appreciated.

Ron

I wanna know how in the world they can reprogram it once its back installed in the truck?!?!

maybe they gave up installing rebuilt units and want to put a mega squirt or similar standalone in there... then tune it to the vehicle? lol if thats the case, $100 is a decent price! lol

Thanks for posting.

After posting I called Av-Pro in Florida (they repaired the ECU) and he also said that Mazda didn't know what they were talking about. That this ECU can not have its firmware flashed (or whatever they thought they had to do to it).

Nick said just to reinstall it.

Again... thanks for taking the time to post.
