Picture an Accord with an H22 swap. Would the car run at all with a F22 ECU? What do you think would happen?

 

also depending on the type of motor and F22 ecu? many variants will respond differently,but most of them will run the motor .

don't expect performance

 

Both the ECU and motor are VTEC. So a ECU for aSOHC car with an external coil can be used on a DOHC motor with an internal coil? I won't mess my engine up?

 

I had to temporarily use the F22 ecu on my H22a Accord while i was waiting for a P13 to be replaced...
My original F22B was a non vtec, running it on the H22A was fine, i wouldnt recommend thrashing your car around until you get a P13 or another ecu that has the correct fuel maps for your DOHC engine... But then again you should be safe as your rev limiter is set at a meezly 6500

 

How long did u use the ECU? What were the noticeable differences?

 

I had it in my car for about 3 weeks, after i got the P13 it was a hell of a lot different!

With a F22 your car feels real sluggish, your revs take ages to build up and overall it just feels like all that $$ you spent on the conversion did jack all cause it feels like a SOHC engine

 

I used my 91 Accord ECU for like 6 months without any problems. Matter of fact the car pulled like a monster and I was whiping Stock LS b-series cars all day. However not having Vtec can leave a withdrawl symptoms..

No problems with idle or sluggishness either..

 

Did you have to do some wiring since the OBD I H22s are internal coils and the F22s are external coil? How did u get the F22 ECU hooked up?

 

Just plug in the ECU and go. Assuming your car is already ODB I.
