ECU question, please help!!

[MA70_452]

I have got a mkIII UK spec non-turbo supra, I would like to know what type of ECU do i have, is it an OBD0 or something else?

Also I have found a software called ECU Control v5 which they are compatible with OBD0 and OBD1, it could do a datalogging, so i wonder is it possible to connect it to my supra?

if i wrong i apologize but last time i checked it was OBD0 because OBD1 has the special hook up port as does OBD2 our cars don't have either we have to jumper.

So our ECU is not even an OBD0? Is that what you are saying Boss302??

It is technically OBDI. OBD0 is a quote unquote Honda thing.

OBDI didn't even become OBDI until the introduction of OBDII. Pryer to OBDII, all systems were just called OBD

OBDII is the only system that has a universial diagnostics plug. Pryer systems were manufacture specific as to how to run diagnostics whether it be plug or jumper and most only need jumper and some dont even need a jumper like chrysler/jeep/eagle products which is just a matter of cycling the key 3 times and then leaving it on and the ECU goes to diag. mod.

What cj said. I wish they were OBD-II though. It'd make life a lot easier. Nothing beats a good scan tool and there have been times I'd have killed for freeze frame on a 7M.
