Little update, car now has an MoT.
Still have a TPS related problem that I can't get to the bottom of. Tried everything and now my wiring loom looks like a rats nest.
Starting to loose faith in the car.
Any ideas anyone? To cut a long story short,
What happens is at Wot on boost the Tps trace will drop to around 80% or at its worst 0%, this happens for approx 100ms which makes the injector signal drop a bit but boost remains constant, which makes the mixture lean and I then hit a lean protection.
I can't carry on with the build until this is fixed, I've re wired the Tps, new TPS, re scaled the Tps 1000 times, ecu wiring, relocated the battery to the engine bay to rule out any earthing faults, new alternator new battery the list goes on.
Just at my wits end with it guys so any input would be appreciated.
