Y33 guys - check something out for me please

[RobertsnewQ]

I've started doing a little research on the Y33 ECU. I need a couple of things:

1. A ECCS wiring diagram for each year. 2. Someone to check if the car has BOTH a grey Consult connector and a OBD-II connector. PM me for pics of either if you don't know.

Robert... heres a link to all the Y33 FSM

Also attached is the wiring diagram from i think a 98...

Robert, my car has an OBDII and a grey Consult connectors. Hope this helps.

[RobertsnewQ]

That does. From the wiring diagrams I've seen, it looks like 97-99 Y33s have BOTH connectors and will be easier to modify.

Later cars have only OBD-II and I'm not clear on the protocol.

This is goood news. I can't wait to hear the results!

[RobertsnewQ]

Well, don't get too excited yet - this is all kind of theoretical.

I need to get an ECU connector from a Y33. I'll call around some junkyards tomorrow.

Then I need to design a custom board to replace the processor in the ECU.

Then I need to desolder the processor and install it on the custom board.

Then I have to rewrite some of the ECU's internal code to access the memory I place on the board.

THEN I have to find someone with a Y33 who will let me tune it.

THEN I have to find enough people to pay enough $ for it to make the whole thing worth while.

I still haven't gotten to step 1...

This may end up being just plain too expensive, but I will certainly keep people posted.

The Y33 stuff does come after the late G50, and after the TCU reprogramming.

Well I'd be happy to meet up and let you tinker with mine! But it does sound like a major pain in the butt.

glad to see your at least working on it, after you told meabout i probably would have given up.....
