ok so i'm doing a bit of research on LH 2.4 ECU's to see what i can find out about them since many have a few varibles such as cold start and EGR. and then others will run BOV's and others won't and some have fuel cut higher than others.
so far this is what i've figured out
937 ECU - car came equipted w/o a EGR valve and w/o a cold start injector. can run a BOV w/o stalling. car will get check engine light but a BOV can and does work. has AMM fuel cut but not idea of voltage. anyone w/ this ECU can you measure the voltage u are getting @the AMM when you hit fuel cut??
939 ECU - car came equipted w/ a EGR valve and w/o a cold start injector. can not run a BOV as car stalls not matter how you shim the BOV. have yet to test for fuel cut and where it is
563 ECU- car came equipted w/o a EGR valve and w/ a cold start injector. do not know if can run a BOV as waiting to hear back from people. so far testing from a few have shown the stock AMM to be pulling over 5.4V's and NOT hit fuel cut yet. this is w/ the stock 13c @16psi.
560 ECU- car came equipted w/ a EGR valve and w/ a cold start injector. do not know yet if car can run a BOV, will test once i get the 91 running. from my previous driving i have run 16+psi w/ an open downpipe and not seen a fuel cut. i have had boost spikes to 22psi and not had any kind of cut because of to much air flowing past the AMM. once i get the car running w/ a 15g i will measure voltage and see where cut is
so far from the few guys i've talked to i've figured this much out
the 937 ECU was in a 93 940T
the 939 ECU was in a 92 940T
the 563 ECU was in a 90 760T
the 563 ECU was in a 90/91 740T
so far that's the little bit of info i've found ... i'd love for any more LH 2.4 guys to post here letting me know what thier ECU # is and what it came w/ be it EGR or cold start or not.. and if they can run a BOV and where thier fuel cut is if any. once we figure this little junk out we will see if we can swap ECU between these cars and see if LH can live w/ a wrong/different than stock ECU even tho it controlls the same things
thanks
