crank position sender

ok i am attempting to fit an aftermarket ecu to my abf engined golf but i just cannot get a spark. now the ecu supplier insists it is my crank position sender or wheel at fault. i can see the wheel through the hole and it looks ok and it spins over with the engine. i have bought a new [pattern ] sender unit but to no avail. anyone any thoughts or anything as im stuck.

 

Is the ECU set up to the type of trigger wheel on your car?

Not 100% sure but I think the ABF is a 60-1 wheel where as most aftermarket ECUs require a 36-1.

I maybe wrong, but it's something worth looking into.

 

think it may actually be 60/2 but im not sure . i did ask for ecu to be set up for this engine but yes something for me to look at and type of suggestion i was hoping for cheers.

 

what ems are you running does the rev counter do anything when cranking the car over if it does then i doubt the vr sensor is naff more likely to be settings

and yes 60-2 trigger wheel is what you have are the triggers set in the ecu ??

 

the trigger should be set in the ecu as i specified this engine when i ordered it but perhaps not. the rev counter dosnt move as i havent connected it yet as i havent sorted where to connect it on the car.

 

what coil dizzy you using

 

abf coil and dizzy although going distributorless once ive got it going.

 

have you got the dizzy wired up ok ? to the ecu ect

 

as far as i can tell it is all wired up correctly. the dizzy does nothing but distributes the spark.

 

What ECU is this? Recheck wiring on 3 pin terminal of VR sender. 1 is - ve 2 (middle) is the signal and 3 is +ve. You may find you need to set up the trigger settings to run on wasted spark. Crank wheel is a 60-2 type.

 

What way are you looking at the sensor when numbering the pins, my sensor pins aren't numbered.

 

5 year old thread bumped?

 

Hey man, its in the section index, thats what its there for

 

Of course. What i'm saying is that half the members that replied to this thread have been away for a while. Your question is simple though and i'm sure someone will help you. I can't because i'm using another sensor

 

No bother, it'll have to wait anyway, going away working for the next 4 weeks so surely I'll have an answer by then

 

Hehe patience is the one sure thing that is needed in the job

 

Too right man, nearly lost the plot with it today, just need more time at it without interruption!

 

I'm sure you will get there

 

ABF has hall effect sensor and most standalone ecu's need a vr sensor.

 

i had the same problem mine was set for vr not hall no cranking pulse no spark need seting for hall
