I have a 99'ek w/98'ls in it. my problem is that my ls ecu is having problems running with it. so i have my p2E cx ecu running my ls,and its running real rich and im spending way too much on gas! so when i put my ls ecu in it used to crank right over but would turn off with any sudden move to the ecu,now it would crank and maybe run for a min. and bog down than shut off. any ideas..would greatly appreciate it. thanks

The P2E is a DX ECU, which is a D16Y7, a relatively small, very fuel efficient engine.

If it's running rich there, there's a problem, if anything it should run lean there. It has about the same redline as an LS, but the LS def. requires more fuel.

Do you have the OEM fuel components, or are you running a different FPR or fuel pump or something?
