I just got my z6 swapped into my ef and converted from dpfi to mpfi and obd0 to obd1. Turned the key and the car started right up, but it wont rev well and when it gets at about half throttle it acts as if it's hitting the fuel cut. Any ideas what would cause this? It's not throwing any codes.
thanks

 

did u swap the TPS wires ... part of the DPFI -> MPFI conversion...

 

I cut the tps plug off of a mpfi harness and used that...so I shouldn't have had to switch the wires right?

 

Swap the two outside wires and see what it does with the tps. I think it has more to do with how it's pinned at the ecu than the actual plug.

 

swapped the two wires at the tps and my ecu is good, but the car still runs the same

 

what ecu r u running
