[Rotary_Rocket_87]

I have been researching alot because I also plan to run a T04 (but it's a B). The only advice I can give you is on engine management. Having read quite a bit on this subject I think the Microtech ECU is the most rotary freindly. They can provide you with harness that will be the simplest to install using the factory sensors ect. and they also have a very clear wiring diagram to show you which wires go where. The base maps that they provide are well done and need only a few tweaks here and there, so tuning should be easier. I hope I could help, and if I have said anything that isn't accurate I hope someone with better knowledge will correct me.
