13. MAF to MAP Conversion Part 5
So now that I had a new fuel map I needed to change my wiring, I now disconnected the MAF input from both the DET & the ECU, leaving the sensor side of the light green wire with black stripe unplugged, I connected analog out (pin 17) to the ECU side of the light green wire with black stripe:
- MAF In = Nothing
- MAF Out = DET pin 17 - this goes to ECU pin 2L Light Green wire with Black stripe in connector 2
Now it was the moment of truth time to try to drive the car with no MAF input. In all honesty I was surprised that it worked as well as it did, the car starts, idles, and drives, however, it is a bit stumbly and feels down on power, there are also hesitant spots in the 3-4k rev range.
Obviously it will be difficult to know what is going on without wideband AFR's so that is the next job I need to get sorted so I can start logging the AFR's to help me understand where the fuel table needs cleaning up and getting the car running properly.
