Given you're on a (half) decent aftermarket ecu and you've just made a new loom, why aren't you using individual coilpacks?

[quimbles]

At least we can plug it in now lol.

Zinc passivated mild steel.

Sorry don't know how to reply tapatalk

What material is the 36-1 made from? Just a thought.

Wheel is steel, so should work.

Ah great that's good to know

There's also a trigger sync test in the software, have you checked that?

Yeah, found that. Software is showing the trigger wheel syncing. The software has been a great help in helping diagnose and rule things out!!

If you need me to check any readings on the ECU just let me know

So..... It’s not the coil pack ☹️☹️☹️

Another look today and I have confirmed there is a spark (coilpack on top of engine when cranking and each plug sparking)

I can smell fuel, but how can I confirm I have it (plugs are wet which is what I expected)...

If I have fuel and spark, I guess the only thing it can be is timing?

TPS? Think that's the only other one left

TPS is ok on the software (it’s only 6 months old)

you can pull the fuel rail open on one of the clips to see if there's fuel........ its a bit messy mind!  just prising it open a little will do.  ive had a leak there before when its running.

 

there ant that many sensors it can be, totally baffled!

 

i feel your frustration.... my car has a misfire.  I left it out in the rain the other week tho, so im hoping its the obvious fix.

Another hour in the garage tonight playing with the crank position sensor. Software showed it syncing regardless of which way it is plugged in, and will also show syncing if a different trigger wheel is selected (as long as it’s not too dissimilar). Also tried a new sensor, but same outcome....

So, latest thinking is trigger wheel / timing...

You tried putting 90 and 270 in the offset. Although I don't think it'll except 270. Maybe turning the sensor round...unsure

Now this is probably total b0llocks.

Does the circumference of the trigger make any difference?

Also had a random problem at the start where the software didn't prompt for the ECU type and it didn't install the right firmware.

Anyways it has to be the trigger!

This. It's was my problem when installed ITBs first time. I installed trigger wheel with the wrong offset, signal was totally OK, but no the phase.

No start. Probably you can even configure offset in the ECU software.

Still wasn’t running, so put my old alpha ecu with stage 1 map on and it wouldn’t run either!! Then fitted gaffers old alpha ecu with stage 2 map and she ran fine!!

Looks like the stage 1 map was far enough off to not even start the engine!! Who would have thought there would be that much difference!!
