Those pictures are the exact same. You are just looking at one of them backwards and upside down. I'm not 100% sure JDM ecu will work but you can try. I heard they don't have OBD standards over there.Okay, so I am repinning a harness from Aristo, to US ODBII and the adapter I planned to use, is not gonna work. So I am going to connect directly to the bluetooth ODBII scanner. If I was to connect the four individual wires, this is how they'd go.... Right?
Will boost actually be accurate with that? I thought the purpose of a Boost Cut Controller was to fool the ecu into thinking the car is at a boost level below where boost cut would normally be. Am I wrong in this? I'd imagine you'd have to read boost pressure direct from a sensor and not from the ECU signal after BCC to get an accurate responseDirectly soldered the ECU wires to the terminals on the scanner and we have lift-off!!!
I've heard "backwards compatible," regarding CPS circuits and other pieces. I plan to double-check soon tho, since I have an OBDI ECU available as a spare/backup. I'll have to look, but don't remember changing any power wires/signal which would short anything out, so maybe I'll put the OBDI ECU on there and see what happens.For all you guys doing this swap. What about going from OBD2 to a OBD1? Anything needs to be done that I am unaware of for this?
Please, nobody to help me ?Hi,
I put an OBD2 ECU in my MKIV of 1996 (OBD1), but by making a check, I have a code error 1630p powertrain.
And I have the green light " TRC " which ignites when I start the engine.
And I also have the light "red triangle" which also ignites !
What are the solutions for these problems ?
Thanks for your help
Finally I have a concrete answer with my problem. Thanks very muchYou lose function of the traction control when you switch from OBD1 to OBD2. The systems are different. That's why you are getting the code P1630, and TRAC OFF lights up.
Yes, the diagnostic trouble code P1630 will trigger the /!\. I also get codes for my HKS 264 cams, and occasionally the rear O2.Finally I have a concrete answer with my problem. Thanks very much
For the master warning light /!\ in red square, it's also switched on because of that ?
Thanks for your help
