i have a strange *** ecu here and im trying to figure out what its from

it says P70
its OBD1
its like 3/4 the size of a standard honda ecu
it behaves similar to that of a p28 (redline, vtec etc)
it came socketed stock
also, it doesnt have the smaller blank chip in it.
there is no jumper wire, and if i remove the chip, i get a solid CEL.
i also noticed that it doesnt look for a vtec pressure switch.

any 1 have any clue as to what car this may be from?

 

Is it a JDM ecu, some of those are smaller.

ye, but ive never seen 1 chipped stock...

 

P70 : 92-95 OBD-1 Domani (sohc vtec zc - no oil pressure sensor reading)

 

some obd1 ecu's use an external rom like the obd0 ecu's, all you have to do is remove the stock eprom, and solder in a zif socket and you're good to go.

 

I had a problem with the auto po8's. Converting to 5 spd work but gettin it to run an external rom wasnt happen. Funky ecu alot of the jdm stuff is a little odd.

 

the process of converting a jdm auto ecu to manual is different than converting a usdm ecu. you don't just jump rp18, but actually have to change the value from 2.4 ohm to 1.4 ohm, that may be your problem there

 

actually from my experince rp17 just needs to be removed. I have done this to alot of ecu's of the years and never had any problems
