obd2 f22b1

[Jmells93]

i was wondering if neone culd help me i recently blew the motor in my 93 accord so i decided to buy a f22b1. i went and bought an obd2 instead of obd1 so now i am stuck with this swap for about 4 months now with no progress i am ready o fire it up soon but i have some wiring issues. FIrst im looking for a pinout for the ecu for a 96 or 97 accord which i believe to b a POH or POJ, which of course i cant find... I was also wondering if it wuld b bad to run the motor without hooking up the tdc sensor near the timing belt cover... i am using my obd1 dizzy n there is a way to wire it in but i havent found the write up for it i guess..... if anyone can help id be very very thankful

u should used the obd1 f22a harness to keep the motor obd1.but u have to use the black box on the firewall.alsso use a ecu for a 94-95 accord with the vtec..or not...(dont kno if the b1 is vtec).

I'm no expert in swapping or changing OBD-II to OBD-I, but I think since you have the VTEC F22B1 you will need to use the ECU from the 1994-95 Honda Accord in order to convert to OBD-I and control the VTEC system. You may be able to retain your distributor, but I am not sure.

Leaving the TDC senor disconnected will trigger the CEL for TDC if your F22Ax ECU is designed to look for that at start-up, if so, you may also trigger a random misfire code and have a rough start (you may have to shut off the motor and try again until the ECU gets the spark timing right, I think it has to make a guess when it looses the TDC sensor).

thank you... i switched the harness to the f22a haarness.. and to use the boxon the firewall how wuld i wire that up or is it pretty self explainitory

self explainitory..just put the 3-4 vacume lines anywere as long as there on the intake manifold.i dont think the plugs for the black box are on the motor harness there on there own harness.and ull have one extra map but u can leave it alone its ontop of the throttle body.
