OBD1, OBD2, which hondata to order?

**STiR** · 18-03-2009 02:37 PM

Hi guys,

My car is OBD1 (EG civic) currently running OBD2 ECU (power FC) as engine is B18CR.

I want to purchase a hondata s300 with a new ECU, however I'm not sure which one to order. Do I order an OBD1 ECU, or an OBD2 ECU?

I was looking at this from the States:

how are you running the powerfc on the current engine? is it straight from the harness to ecu or is there a conversion harness in between?

isnt power fc obd2

**damo46** · 18-03-2009 06:24 PM

power fc for a dc2r is obd2a... So You must be running a conversion harness unless you have the full dc2r wiring harness running the whole car..
You have obd2a im sure

Get a OBD1 Hondata S300. That way you can recoup some money back on covnersion harness.

OK Yonas told me my car is OBD1 and my ECU is OBD2. I like your suggestion fatboyz39 to get an OBD1 Hondata s300 which will plug straight in, and sell the powerFC and the conversion harness.

Looks like an OBD1 hondata will cost me around $1300 imported, and tuning will cost around 550. That's under 1900 all up. Alternatively, I could get a Motec m400 (or m4?) brand new fitted and tuned for 3200 all up. Hmmm...not sure

Thought of Vipec plug and play? Thats what we are using with some pleasing results.

Is there much support for those ECUs? I need something that will be able to tune with quads for a good street/track set up.

It's nice to sound technical huh. Too bad none of the info you've given above means anything to the OP. It doesn't mean anything what car the motor was taken from...

As stated earlier, the car is OBD1 with a jumper harness to run the PFC. So getting an OBD1 S300 is what you're after.

LOL barefoot that's harsh... although I was wondering why I was feeling like there were conflicting messages coming through!

Thanks for clearing that up. I'll either order an OBD1 s300 which is quite a cost effective solution, or a motec if i can get a good price. Thanks guys!

lol, it's a big problem on this forum. everyone just giving out information with knowing the facts, it confuses people.

Since you're in Melbourne, try Andy @ AK Motorsports in the traders section, and give Neptune (seems very similar to S300) a go. With the current exchange rates being so crazy, he might be able to offer you something for a lot less.
