Hi guys i need backup with this problem. I bought a ems2 30-6040(ob1), epm, cop and twin fire. I re-check the wirings (i follow the ems 30-1000 epm wiring), tried many ign phasing configuration and cant get the engine start. Coils got spark and fuel. I could only got engine start roghly with a lot of detonation (like on 2 cylinders).

Spec:
civic 97
b20z
stock injectors
turbo


Regards

 

go on the aem forum and follow the wireing directions on their the ones they send in the kit are usually wrong make sure u wire the twinfire red wires to switched constant 12volt go into the ignition switch thats usually where peoplke mess up does it back fire when the ignition switch is turning into the off position ??

 

What exactly is a switched constant 12V? LOL. The Twin Fire needs a Constant 12V (10AWG Red Lead directly from the box) and there are (2) 18AWG Red Leads off the deutsch subharness that need switched 12V.

What ign phasing configurations are you using?

What do you have the switches set to on the Twin Fire?

Did you sync timing?

 

Sync timing.I had the same problem until we sync the timing.

 

twin fire switch? u mean the 3 little switches that enable multispark, wasted spark, etc?
I got the engine start! but sounds like it is out of timing or has a dead cylinder. Engine is runing roughly.

I followed this wiring, beau from aem technical support is helping me

configuration phasing is the same as the like told me to set. I noticed that when i active the 4 fuel injector on coil-inj, the engine rpm weaken slighly but it doesnt shut off. When i disactived it the engine ilde better.

Any suggestion guys??

 

timing sync, i dont remember well. I think i did, but i will try again.

Thanks for the ideas!

 

guys!! I still cant get the engine idle fine. Its start but it has a dead cylinder on number 2. I checked the signals from the aem tunner and the number 2 fuel injector is not delivering fuel into the cylinder chamber. I switch the number 2 fuel injector plug and it spray, the problem is the number 2 fuel injector cable i guess.
I pulled out all the cops with spark plug pluged and start them to see the spark, all got spark but coil 1,2 were stroger than 3 and 4.
I read on evoluntion.net an evo that has the same problem.


Hoping someone can help
