Hi (any experts out there),


I was directed here for expert help.... I'm looking to solve my Oddy 97 swap problem.
To summurize, I've replace the original engine with a JDM F22b (accord OBD1, non-vtec, automatic) engine. The way it's been done is I used an OBD1 dizzy and ran the wires from the dizzy to the (red, green, blue, white wires) on the crank since the Harness and ECU are still Original (obd2).

this is how it's connected:

THis is how I soldered the OBD2 connector to the OBD1 dizzy:

connector------------ dizzy
green-----------------green
yellow/green---------yellow/green
black------------------white
yellow-----------------orange


then there's gonna be 4 more wires comin off the OBD1 dizzy, which get extended down to the TDC and CKP on the oil pump (again, i cut the bottom connector off and soldered them):

OBD1 dizzy------- OBD2 TDC & CKP:
blue/green----------blue
blue/yellow --------white
orange/blue--------green
white/blue----------red



Problem is the car idles horribly and also does not start right away (chugs a few secs before starting). Sometimes it stalls when stopped at a red light. Even worse, I'm getting random misfires on all cylinders and ECU light flashes when above 120km per hour. Other then that the car runs fine on highway and gives 12km per liter on highway.

I've checked every other problem that could be, so please don't waste your time asking me about the other parts (I've changed most of them). My mechanic who did the swap says that the problem is my ECU. So i replaced with a similar Accord EX Auto non-vtec 2.2liter ECU and nothing changed (proving that he was wrong to say that my ECU was bad).

Then I purchased an Accord 95 (xxx-POB-xx) non-VTEC Auto ECU connected it with a conversion harness but car won't start. Probably because it's automatic and these harnesses are only for manual cars.

So now I'm thinking that the only way is to convert the engine to OBD2 by replacing all these from a USDM post 96 Accord OBD2 engine:

*Oil pump
*Crankshaft Position Sensor
*Crankshaft Timing Gear (OBD2 one has 12 pins on it)
*Crankshaft Pulley (harmonic balancer pulleY)

Is this my only way around the problem? Or do I still have an easier way around this problem like by chipping the ECU as explained in this article?

I'm not sure the above article applies to me but if it does, can you please explain to me what I would need to do this. I've already got
a red conversion harness (that's often sold as for manual cars only).

Your help would be greatly appreciated.

Thank you!

 

i belive you could have just swapped your obd2 injectors and obd2 dizzy to the new motor and just used a obd2-obd1 jump harness with a obd1 ecu.

 

Best option I found was the first one.... Bro I did the same thing and its taken exactly one year o figure this out...
