Just did this to a friends car. He's running an EDM P28 chipped by me, running a xenocron basemap, with a xenocron OBD2B-OBD1 conversion harness. This is on a 99 coupe with a B16 (whats known as an EM1 over here).

The car is throwing codes 22 vtec pressure switch and 36 which seems to relate to traction control?

I'm a bit stumped as to why, the car is known good and the chipping job was top notch. No oil pressure problems etc.

He seems to be struggling to find the wiring in his loom that goes to the pressure switch and i haven't a sodding clue what the traction control CEL is about!

Any help would be most appreciated.

 

the 22 can be disabled by connecting pin A4 to D6

the 36 is odd but might go away after getting rid of that code...maybe using a different base code (i use 203) would eliminate the 36 in that particular ECU.
