pectel t2 ecu is £650 and a custom wiring harness is gonna be around £450 , then you ve got the mapping at around the £200/300 mark and i would personally choose ahmed bajoo . pectel is a great product with many high powered cars 650+bhp cossie from norway running the t2. speak to ian howell at tech@fiestafrenzy.co.uk as he is still selling of the shelf parts and also i am sure hes the only one to run this set up as we had to resolve the flybywire throttle and coil and some other parts as the owner wanted to keep the orginal dash etc. we made a custom wrc style overbriaded wiring harness which simple just clipped in without cutting any of the orginal wiring out so it was like a bolt on kit
hope this helps mate
cheers paul
