Hello evryone.
We have put an emu ecu on Subaru WRX,we have connect ignition and injection on full sequential way but we have problem with crank trigger.
The engine doesnt startup easy and most of the times we have try to start it up doesnt work.
Can you help us with a start up file basic on crank trigger,ignition and injection mode?
Thank you in advance

If You need our help, We need more information, ... year of the car. Old cars use different crank pattern then new one.
Also it would be nice to have Your calibration file, log from starting attempts and scope from cranking.

Try to set ignition output offset to 1 in ignition output table

Injector Phase is set incorrectly, FYI.
should be set:
injector 1: phase 1
injector 2: phase 3
injector 3: phase 2
injector 4: phase 4
providing you have cylinder 1's injector connected to injector output 1, and so on.
From the factory the 97-98 impreza uses a single coil pack, with 2 coils - it fires in batch fire, yet you have your ignition set to be fully sequential.
if you are using the factory coil pack, with HT leads ignition output should be set thus:
Ignition event 1: Ignition output 1
ignition event 2: Ignition output 2
ignition event 3: Ignition output 1
ignition event 4: Ignition output 2
If, however, you are using individual coils attached to all four ignition outputs (maybe from the later 01+ car) then you have it set correctly.
*However*
If you are using the newer individual coils, your dwell time is off, you want it to be around 3ms at running temp & voltage.
*WARNING*
You have "coil type" set to "coils without amplifier" - this is probably incorrect.
If you are running the standard 97-98 coilpack, this is driven by an ignition amplifier, so your output type is wrong.
If you are running the 01+ individual coils these are also driven by an internal amplifier, so your output type, again, is wrong.
In both the above situations you need to set the "coil type" to "coils with built in amplifier".
