Do I have a CEL or what? Calling all CRX HF-Z1 swappers...
Premise: '89 CRX HF w/ D15Z1 swap, ECU conversion harness, 5-wire O2, stock down to the rusted exhaust tip, HF tranny, DIY grounding kit
I have to put this nagging question to rest. I've never owned any '88-up Honda before this btw, so go easy. I am 95% done on my '89 CRX HF+Z1 swap and besides a Rywire ECU conversion harness, I did all the wiring myself, with no prior soldering experience or help besides the Bible ( = Helms) and Matt T., Bunger, and SVOboy among others on this site who have greatly helped me out over the last two years on this endeavor. Anyway, the car starts/runs/drives, with slight hesitation sometimes and the occasional rev hang but otherwise awesome. I turn the car to RUN, the CEL blinks on (I guess to let me know the light works), then goes off and stays off. My question is, does this mean I have NO codes? When I ground the ECU Malfunction checker w/ a rocker switch, I get a steady CEL, no blinks. My '85 CRX Si has 4 LEDs on the ECU to let me know what's up. I've never dealt w/ OBD-0 or OBD-1 before this so it's all new to me. I also find it hard to believe I wired it all perfect the first time, although I did take a ridiculous amount of time to complete it last winter.
OK, question two, how perceivable is VTEC-E? With the P07 ECU, car in neutral, revving the car between 1.5-6k gives no distinct powerband changes. I've only driven the car 4 miles so I have yet to test it on-road. I didn't expect a kick in the pants just a variation from the norm. Supposedly VTEC kicks in at 2.2k on a Z1, IIRC. I had a spare P05 ECU ('92-95 CX) laying around and hooked it up, to my surprise the car run just the same (to me), maybe even a bit smooth on liftoff, but I would assume I had no VTEC engagment w/ this ECU. I won't know more until I assemble the rest of the car and get her street legal. More to come, surely. Thanks for listening to my ramble, Mak
'85 CRX Si Original EW3 @ 254k...suck it Detroit
'89 CRX HF-Z1 ~ When haste is needed
'97 Civic DX Hatch ~ Formerly 600hp, now 0hp, soon 115hp.
yup steady light means no cel! congrats first time and done right!! vtec-e i don't think would be too detectable as a regular vtec is. i think it would make a little grunt when vtec hits but nothing big?!
