Hey,
Just picked up a Chipped/Socketed P61 ECU from the user " gsrhb7" on HT. When he sent me a picture he didn't take a picture of the harness that was tucked underneath one of the boards. Also theres a 4-pin thats just open...and the harness thats grounded in the picture is a 3-pin.

Can someone please tell me what the hell that stuff is used for cause the seller didnt mention anything about it...

 

anyone?

 

the 4-pin plug is CN2, used for datalogging.

the three pin plug I'm not sure, it looks a little like a MCU memory dump harness.

post the pic and question on pgmfi.

 

That plug thats grounded with the yellow wire....

What does that do exactly?

Can i run the ECU with that not grounded or what?

I posted this on PGMFI but that forum is kinda slow.

 

the lose plug(3 cables) is for PGMFI RTP.
it's connected to MCU

(I didn't recognize it at first)
the jumper is in place to bypass the modification made to the ECU. It needs to be there so the ECU can operate like normal.
If you'd like to be able to pull that plug out, solder in a jumper to connect the two locations.
But it will work fine with it in there.

 

Thanks guys...this is all a new language to me..so bear with me..

Whats all this RTP, MCU stuff used for?

 

RTP - real time programming. (think updatable on the fly chip) Moates Ostrich is basically the same thing, the PGMFI unit was open source.

MCU - Microcontroller, the main processor of the ECU.
