Hondata

Anything ever come of this? K24A2 swapped into a 91 MR2, Krpo V4. Car's been a summer time DD for two years now, same tune, nothing's been changed on the car. Regapped the plugs to .25 since some were around .20. Voltages are fine. I can slowly accelerate in 1st or 2nd and around 4k it starts buckin...

So all this time and I just figured out I've been trying to splice into the wrong harness!! I was going for connector A not E, but I'm still having no luck with E either. I found this website after continual Google searches for RSX auto ECU's, but of the few pins in my E connector, non match colorwi...

I'm having an issue where I wired in an OBDII port, I can connect the OBDII dongle but Hondata says "Ignition Not On"...any advice?

Are pins 23 and 29 still relative when to my ECU? I just don't wanna hookup to the wrong pins and fry something if some pins changed around between ECU's. My pubs and colors match the picture below.

SOMEONE PLEASE HELP!!!!!!!

I finally found the correct matching colors pinout for my ECU which is an automatic for some reason. I just need to know which wires from this harness are used to make an OBDII port.

Nothing's been physically changed in the car, tuned by Kenny from SFR but he's an hour away and he didn't wire the car so he says he can't help. I bought the car already K swapped, they worked for a while but at some point they stopped reading correctly on my tablet. My AEM wideband gauge still read...

I didn't think I'd literally be asking the hardest question ever, hence the lack of replies...

Bumpski for ANYONE reading this with a Hondata OBDII port wired in like the pics I posted above. Wiring colors aren't consistent based on Google searches so pin location within the harness would be super helpful, please.

Bump, please...I never thought 4 wires would give me this much headache :-)

You need to check all your wiring as it sounds like something is not wired in the vehicle correctly. I would suggest you use the factory service manual for the RSX. Car runs and drives perfectly fine though, even connects via Bluetooth to my phone or a tablet without issue. Problem is my JOYING bra...

Bumping this post since it's been over a year, I've made multiple attempts and still no luck. A friend with a K swapped Civic hatch has a KPro V4 in his car as well, but his ECU looks different in that it doesn't have pins going from the circuit board to the middle two connectors (I'm guessing my EC...

So, LONG story short but I've got a Joying stereo installed on my K swapped 91 MR2. The stereo sees the KPro but refuses to connect (Joying is of no help), so I'm trying to connect from the KPro serial to the Joying USB but I don't see ANY options within KPro to connect via USB instead of Bluetooth....

Sorry, I missed this reply. It'll give me that Ignition Not On warning with the engine running, so does power need to be applied somewhere within the KPro to change that?
