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??

Lean? A 1.7 MPS would be used to seeing less suction than a 2.0 puts out, right? And in the highter RPMS when the TB is open the MP will increase towards atmiospheric which would be the same for both cars, I would suspect. Doesn't the MPS go to full rich when the hose is disconnected/ reading atmospheric? The FI brains for the cars are not an issue if you are using the 2.0 injectors on the 2.0 engine. I would actually suspect a slightly rich running condition, but YMMV. Am I thinking wrong?
Absoleutely monitor your plugs, though. Its easy and tells you a lot. Check Brad Ander's site for more info. http://members.rennlist.com/pbanders/ |
