I built this weird obd0 obd1 hybrid car. 1991 civic dx with a jdm 1992-1995 d15b swap. I kept the dpfi for fuel economy, but since the dist wouldn't work from the 91 onto the 92 head I wired the 92 dist up to the ecu. The car started, but flashes 4 on the ecu, the crank pos sens. I'm not sure if the ecu doesn't understand the dist or the crank pos sens is really bad. So, what you think?

 

convert to obd1 mpfi. dpfi is inefficient and is only costing you gas mileage.

 

yea man convert to obd1. dpfi doesnt save you gas. mpfi is more gas friendly
