Also the car is going to be using E85.
i have asked the seller from ebay these questions and this was his reply to me was.
Daniel,
The P2000 can control your engine also, but it will either have to be wired up to the engine or use one of our patch loom kits , here are your options:
1.P2000 flying lead kit , this kit has to be wired up into your engine (price with dash $2965 ) item # 120616364449
2.P2000 R32 patch loom kit,this kit plugs into your current factory harness(price with dash $2965)item #120615981060,(advertised for 300zx however it is the same kit)
3.Pro Platinum R32 Plug and Play ECU , this ECU plugs straight into your factory harness also (price with dash $2717) item # 110591763827
Regarding the MAP sensor , I'll suggest the Haltech 3 BAR map that can be added to your order , item # 110659176040
If your current engine harness is in good condition , then I'll suggest going with option #3 , the PRO Platinum is just as powerful as the P2000 , the reason why is slightly cheaper is because it does not require a wiring loom since it plugs direct to the factory wiring harness .
