Ie at 1bar of boost the ECU is recieving 5volts from the map and fuels accordingly. When you fit the jap spec 2JZ map it moves the whole scale back by 25-30%. ie at 1bar the ECU will only be seeing 3.7 volts or whatever.. hence you need 25% bigger injectors to replace the lost fuel and put everything back to stock. 440's are the perfect size and drop straight in. BUT this also means that when you run higher boost (up to 18psi) you are effectively still delivering the same amount of fuel as before.. so.. you need an extra bit of fuel to compensate, provided by the use of 550's. All this means that you keep a fuel cutoff at about 18 psi, something you cant do with just 440's and the stock map. Manny has done this, and its next on my list. Apparently the 550's are a bitch to fit and they need a resistor pack. Then its just a case of a fuel controller and a dyno. There is some discussion about the ignition timing at 18psi as well.. so something like an e-manage instead of a fuel controller may be a good idea. Oh.. and bigger turbos of course HAVING SAID ALL THIS - There is a guy in the UK who specialises in engine management. He is looking into a way of using the 2JZ map without any adverse effects on the ECU... meaning 440's are all thats needed to run 18psi. It will be a small simple unit that intercepts the map line as normal. [Updated on: Sat, 31 January 2004 12:44] [Report message to a moderator]
