Went to junk yard today searching for whatever. I found this in a 94 ex. Its a p28 ecu, I know what the green box is, a socket, but what is the red circle??? I want to throw this on the bay or something, but i need to know what the heck this plug is used for? Tuning???

 

You found a non-virgin ECU. It's socketed for a chip and the ???? is a 4-pin header for data logging.

 

Ya thats the samething in mine same chip and same jumper wire for the manual. Mines a bit dirty lol...how should i clean the board up. its not dusty, just dont look the one you showed me. Also is it worth much??

 

A real good buddy of mine used to put his computer part in his dishwasher, just make sure you dry it out completely. Either that, or he showered with parts too, weird.

Since your ECU was an auto and was converted and that it's no a virgin anymore, it's worth (to me at least) 40 bucks or so. If it was a virgin manual 100-110, virgin auto 80-90 bucks, and converted auto to manual 70-80.

 

Thanks for that info. I might try the dishwasher idea. One more question. What is the data logged used for? Im not to kene one the obd1 stuff. Also did he use dish washer soap?

 

In the shower I don't know what he used[:'(]. But he threw all his boards in an EMPTY dishwasher, no dirty dishes lol, and used regular dishwashing liquids.

Data logging is, well, for logging data. You can hook it up to a laptop and with the right software, you can tune your car live. It also allows you to see what's going on.

 

Ok got ya no dirty pots and pans...lol..maybe if this works ill convert my car to obd1 to use it. would i use hondata and such?

 

you can use any 28 pin chip (eprom). So, yeah, Hondata, Phearable, Crome.... ....they all have there ups and downs. I'm running a phearable chip simply because I don't have a turbo, so the advantages to getting Hondata aren't that great for me.
