ems question

[Mazda_DohC]

i have the mazda f2 2litre engine from a 626 i cant get the pwm frequency for the idler valve any ideas???


also i have a rev limit problem even though i set rev limit on ems to 8000rpm the engine still cuts out at 7000 i have checked everything

the engine running optical ignition could it be inbuilt in the dizzy by mazda or could it be stock pressure regulator im stuffed on this one

check your sync res and trig res settings in the set up menu,if they are on turn one off and vice versa,some engines need them switched around so that they can rev right!

thanks for the replyv syn.13b unfortunately my ems blew up last nite after i started it up the engine cut out and there was a burnt smell coming from the ems ,

now im left without a car because the ems guys are closed on weekends.

i checked all wiring for shorts but all ok seems internal fault
