I'm hoping someone with the Honda engine can tell me if (and where) their vehicle has an OBD plug? If it matters, the car in question has the Hondata K-pro ecu.
Any help would be greatly appreciated.
Thanks

It's probably not wired in if you can't see it under your dash panel. The ecu is behind the seats and you need to run through 3 wires I think to run up to wherever you want it to do to. If you can't source the plugs and connectors locally let me know and I'll knock up some obd cables

Kpro does not use the OBDII connector, if your ECU has Hondata KPro it will have an funny USB port (looks like something a printer would use) on the side of the ECU, along with a sticker on the box with some nonsense binary. "0101100111000"
The software is free from www.hondata.com.
Be carful though, make sure you have the right engine selected weather it's the K20 or K24 they may differ in Valve timing quite a bit, and some variations in head's do not have VVT or Vtec altogether.
You can Modify everything on a 3D scale per RPM/Load just to name a few:
- A/F ratio.
- A/F ratio adjustment per temperature Change.
- +/- Fuel per cylinder to balance power or clear hotspots.
- ignition timing.
- cam timing *if equipped with VVT, usually only intake* per low Cam and/or High Cam phases.
- Stage 1,2,3 Nitrous setup for retarding timing.
- Launch control.
- Boost S/C or T/C... or Both?
- Boost Per Gear (requires gear input).
- Reduced turbo lag on launch control.
- 8 Analog and 8 Digital additional input's *requires custom wiring*
- You can setup a light to flash when detecting a knock, or retard the timing immediately when a knock is detected.
- Ability to view DTC's without using a portable scanner.
- Can record Street/Track Data for later review.
Also don't forget to click the lightning bolt to connect to the car, I don't know how many people complain their KPro does not work because they do not click the button to read the car.

I have an Atom 3 with the K20 Honda. I had to change the ECU to a K-Pro to pass the emissions test in Nevada. The emissions testing is done through the OBDII port, which on my car is next to the ECU on the drivers-side (left) firewall (in the engine compartment).
