I bought a fuel injected 2.0L with all the goodies. The ecu was found to not be sending power to the fuel pump so we put an ecu from a 1.7 in it and - bam - power to fuel pump. We then noticed a engine surging problem at idle and put in an mps from a 1.7 and surging problem went away. What problems can this set up cause??

It will be certainly running too lean all the way, maybe more in the top RPMs, even if you bump the fuel pressure I don't think it will compensate. Running lean is playing with fire I heard.
Edit: I think your best solution, timewise and money wise is to find a good used ECU which shouldn't be too bad since they usually don't break. And have the good MPS calibrated by Jeff or Bleyseng to the proper specs. |
