Daymo's Back! - R32 RB25DET NEO

[DaymoR32]

Here’s how it is in the ECU

and the wiring in the plug is like this

think it is plain white, yellow, green, blue.

You might need to trace it back, or at the very least work out which is 12V (to not use), which one is GND and which goes back to B1 and B2 (to not use).

[DaymoR32]

If it’s been wired to 12v will that have f**ked the sensor?

as I’ve tried changing the wiring to suit as per above, so wired black to yellow and white to green. 
or have I messed that up (I’m terrible with wiring it’s my number one hate 🤣)

Hmmmm not sure, but an assumption is maybe.

A reluctor creates its own voltage so you don't feed it one.

Aye probably dead then 🤣 will probably just pop the stock CAS back on.

i do have the paper wiring diagram with notes on it somewhere so I’ll cross reference that first

Maybe find the spec sheet and see what the resistance of the coil is, possibly it's not fried? Especially if you didn't short it

maybe another thing for me to try? timestamped (i know its the nz wiring kit, but this is on the haltech software side)

You can just swap the pins at the CAS connector side.

You could go old school and use a test light to see which pin is going back to B1 on your ECU

I ended up trying every pin combination. got the car to start once, then rev'd it and it died. then couldnt get it started again.

Threw my toys out the pram and put the stock CAS on and it fired first turn of the key (with backup map reapplied)

I'll re-visit it another day when i get the motivation again.

sounds like you are super close, either the air gap is out OR the trigger arming voltage is too high.

In NSP, just plot the trigger voltage vs. RPM vs. time and when you crank it you'll see what it reaching, adjust the trigger arming to suit

next time i have a full weekend i'll have another play, currently one month away from wedding so have no free time...

Thanks for the pointers though,

Congratulations in advance  

wen baby?

I'm from the UK, everyone knows you buy a Seat or a Skoda as they generally run better than their VW / Audi Brothers 😆

Lololol... Funny between brands reliability changes, yet it's technically the same parts.
