I was looking around doing research on parts, and I went to the Hondata site and read up on their standalone unit. Everything sounds great, but they don't support Non-Vtec ECU's. I'm running a B-18B, so if I wanted to go Hondata w/ boost how would I go about implementing that with my non-vtec ECU?

 

you need an OBD 1 ECU P74 or P75
AN OBD 2 to OBD 1 conversion wiring harness (if you have OBD2 now)
al least hondata 2b you could get 3b, or 4b, depending on what you want
RC 440 or 550 injectors, depending on how much you want to boost

 

oops..OBDwha?? I've got a B18A...sorry. Hondata 3b would be the most I would go..probably boosting 15 psi max after its all said and done.

 

 

If you are using a non-OBD ecu, check out the zdyne ecu conversions.

they got hondata applications for b18b's...better search ahrder on ther site...its got a lot of info

 

He said B18A (non-OBD). You'd have to do an OBDI conversion to use hondata.

 

So if I swapped a fresher LS head on my existing block, then I could run the P74/P75 ecu right? And if so, would the wiring match up or would I need a harness?

Thanks for all your help!

 

I would call hondata, their website says they are working on it, so if it is redy within a certain time period, it would probably be better for you to just wait. If you do do a conversion though might as well go LS/VTEC. Just a thought, keep your options open. If you did do that you would need a p28 ECU. Later,

 

No, the head is not going to make the difference. The difference is in the distributor, injector type, and plug type on a few sensors. It's a lengthly conversion.

However, what you could do is plug in a VTEC ECU from a JDM CRX SiR or Integra XSi, and disable the VTEC. We've done that before, and it works. We are still working on disabling the CEL for VTEC, however.

 

i always though that the 92-93 integras were obd1

 

On Point: 92-93 are OBD-1 the 90-91's are OBD-O............

Dustin: Word up on Zdyne they ROCK!

 

I looked at the Zdyne website briefly...which model ECU would work best with my situation? Based on VaporTrail's suggestions, I may just build the hell out of a fresh LS engine. It all comes down to wherever I get the best price.

I was thinking LS/Vtec..but I dont think LS/Vtec would be reliable and cost effective enough to run 12+ psi of boost.
