106 injection rate

Recommended Posts

Hi iv fitted storm ecu to boosted 106 gti.

I'm sure it runs batch fire and group injection.

It only has crank sensor.  Base timing set to 270 offset and 0 ref.  Injector 1 and 4 are wired together and so are 2 and 3 from standard.

Iv wired no 1 and 4 = inj drive 1 and 2 and 3 = inj drive 2. 

I'm using multi point group but iv also got it running on single point today. Injection rate is set to 540 but I don't think this is correct. Can someone please help. I know it injects out of faze but how far after?

Wiring wise that will be fine and the injection rate should be 1/engine cycle. That will fire all injectors once in 720 crank degs

You want multi-point.  The injection timing is irrelevant since you dont have a cam sensor - the ecu doesnt even know whether you are on exhaust stroke or compression stroke.

Ok guys iv spent all morning on multi point. 760 injection rate 1 cycle. It starts now and again but something just isn't rite!! Please help. Iv bypassed the efi relay and supplied voltage direct to items fuel pump/injectors/coils.pump on constant?

Maybe my trigger settings are wrong. I have a reference of 0 tdc and 267deg in my offset. The two teeth missing are bottom dead when engine cilynder 1 and 4 tdc. The sensor is approximately 90 degree atdc. So basically when my cells have 0 in it should be tdc 20 should be 20btdc someone please clear this up

Can you take a trigger capture with the ECU and post this will let us check arming voltages and a copy of your map so we can check the trigger settings to match.

Hello Adam , on your wiring which is your cylinder "1" ? 

the PSA engine have for cylinder "1" the 1st piston near Gearbox. 

Also the OEM crank sensor is a bit "slow" you need to change the arming voltage as well to make it "sync" faster .

i can send over a wiring for such engines done lot of them ;) 

 

cheers
