I'll have a look at measuring blocks tomorrow.
Airbox fitted -
Intercooler pipe from clocked turbo runs a nice tidy route now
Dropped back onto the wheels just to recover my axle stands for another job, so took a pic for mr sausage
There's probably about 20 mm on the torsion bar yet so dont panic too much about your reverse raking you gurt fanny.
Fitted up the big brake brembo conversion

Got vag com plugged in again.
Not really sure what it means
However, whilst messing about with the chip loose in my fingers - it started and ran fine. Clean as you like, nice steady idle
With no coolant I shut it down again after a few seconds - except now it wouldn't turn off.
pulled battery leads, still running
pulled the big round plug off and it cut out.
Could I get it to start again - could I heck, tried and tried and tried with the chip in similar position - nothing, just fires and dies on the immo.
I've ripped the loom out.

I've been checking through my loom this morning, familiarising myself with what's what, before feeding it all in.
Fingers crossed for you Reg! 🤞👍

It wasn't really a case of starting again from scratch.
I know the loom works, I know I've got enough bits plugged in for it to run so I stuck masking tape on all the disconnected plugs then removed the loom.
Well I say it 'works', there's still the issue that it doesn't turn off on the key, the TPS (throttle position sensor) does nothing apart from read 14.3% all the time and there's an air intake temp sender disconnected somewhere (yet nothing on the air intake pipework to plug anything in?)
So - taking most of the insulation off the remainder of the loom, I pick out all the air con related stuff by following wires around the loom and if they go nowhere near the ECU then they are history.
Then turn to the unknown plugs, tracing them back to the ECU, using an ECU pin out guide to work out what their purpose might be and delete if required.
Somewhere during this stage I realise that the TPS and the MAF have the same plugs, one would sit inside the car and the other outside, one is dirty and the other is clean, because of the way the loom has run in the T4 I've had them swapped over all the time. doh!
I also found the air intake sensor plug which is down near the front of the engine - perhaps it's some kind of ambient sensor??
Bit more slim-fast for the loom
waste wire is in the pile top right.Last edited by regcheeseman; 9 July 2017, 01:16 AM.

Air intake sensor plug? Two wires, one goes to G1 other goes to G2? I've been puzzling over this very plug today - from what I can tell it was never connected to anything engine related in my golf donor. Was it just outside air temperature for the MFA?

It still flags up a fault so should have been connected to something once?
Finished the loom tonight
Relocatd the maf wiring and then wrapped it all up - don't look like much but took a good few hours.Last edited by regcheeseman; 9 July 2017, 01:17 AM.
