Hey everybody this is only my second post so bare with me here, but I have a 96 accord ex f22b1 with an auto to manual swap, bien level 2 cam, and f23 intake manifold swap. I recently bought a chipped p28 ecu tuned to my build but when I plug it up it gives me a code 9 and code 22. Both of which do not appear to have any problems with stock ecu connected. Would just like to hear some opinions on this, or any possible tests I can preform to diagnose the problem, thanks.

 

Bisimoto cam sorry auto correct

 

Something wrong with the tune or the ecu.

The 96 is an OBD-II car - most tuned/chipped ECU's are for OBD-I cars. When the tuner was working on the car what did they say?

 

It has not yet been tuned in the car it was just pre tuned based on my mods. I want to fix these two problems before I take it to get it finely tuned

 

This. What's the stock ECU number? DTC 9 is the crankshaft position sensor (CYP) and DTC 22 is the VTEC oil pressure switch. Different years/engines/OBD versions have different specs for the CYP sensor. 5th Gen OBD2 cars don't have VTEC oil pressure switches but 5th Gen OBD1 cars do. The fact that you don't get the DTCs with the stock ECU but they pop up with the OBD1 ECU tells me that some additional work needs to be done to convert the car to OBD1.

 

I talked to my local tuner and I can get the code 22 disabled for cheap. And he told me that I need to get a obd1 distributor from the junkyard hook it up and wire my existing crank sensor into it to fix the code 9. Will this work if so how would I wire that? And if not what are some other options?

 

Wiring:
A little web searching may yield a DIY and/or pics.

BTW, a typo in my prior post: it's not crankshaft position sensor, it's cylinder position sensor.

 

Check/search for OBD-II to OBD-I swaps. You can run/change wires yourself or there are some places that will sell you the harness.
