thought id add, after 3 weeks waiting for an update from them, i got fed up and went and collected my car this mornig, when i got there i was told by richard that he tested another r34 auto ecu ((from the guys next door!!!)) and the same error came up, he then inspected the coil packs to discover voltage errors, so he made a new earth for them and bam says im not sure if problem is fixed but take it and let me knwo if it happens..
anyway i took it away and my dad and i went and did 212 kms of driving up to glass house mountains giving it a bit of flog , and no warning lights, car is fine.
im so glad that i didnt buy a haltech under the impression from them that my ecu was f**ked, BUT IM ANNOYED I WAITED 3 WEEKS FOR A EARTH WIRE.....(considering they told me they extensivly tested the car to make sure it was def the ecu... and guarenteed me that it was..
I wont be going back there,
