I'm getting ready to convert my '91 CRX B16A running a PW0 to OBD1 so I can use Uberdata. I've read a lot on here and PGMFI and a few other places, but I want to make sure I'm right before spending money. I'm going to need:
Distributor from 92-92 DelSol vtec or GSR. (Can also use from non-B series, but have to cut off one mount?)
P28 ECU from 92-95 Civic SI or EX.
Pigtails to make the conversion harness.
Is this correct?
One thing I don't understand, why a P28 instead of a P30, since the P30 is for a B16A2? I've also read you can use a P06 from Civic DX?
Thanks.

 

dizzy from a B-series ONLY (as far as i know) non-VTEC's need a leg cut off. anything from 92-01 should work (GSR/ITR/all B16's)

ECU...most anythign can be used. most P05/P06/P28/P75/P72/P30... all can be socketed and most can be converted to VTEC if they dont already have VTEC (and i have a couple for sale )

you need a set of OBD1 ECU plugs from the car side and a set of ECU plugs off a ECU board (i suggest a PM5 cuz there ---- anyway...might be hookin these up soon too )

the P30/P72 and i think P71? well the ones from DOHC VTEC cars have knock boards in them...as far as i know the knock sensor in a Honda is useless so it doesnt really matter. in Uberdata you can turn off the KS so no worries...

 

oh and as for the P30 being "ment for a B16"... your replaceing the ROM on it anyway, so a modified P05 can work just the same (aside from the KS ----).

i have run a P05/P06/P28 all in my car with the same tune and no problems, they have all worked just the same...

 

Thanks for the info, that was the idea I was getting, but never saw it in black and white. I'm going to the junkyard but if I come up with nothing (very likely, junkyards around here are worthless) I may look into the ECUs you have.

 

i have an OBD1 B-series NON-VTEC dizzy too...

 

Dustin do you have any Obd-1 Vtec ECU's?
