shark Posted May 20, 2016 Report Share Posted May 20, 2016 Hi everyone, need some advise. I'm currently installing 2x 3uzfe vvti engine to my boat. The standard ecu have immobilizer system which hard to crack. So my next choice is to run stand alone ecu.Beside i can keep the wiring to the minimum. I'm not going to use drive by wire so is it ok to use atom or storm for it?. i dont mind to use 1 ignition output to drive 2 coil but can i transfer the vvti map for the extreme ecu to either atom or storm?. I need the vvti base map cause i can't dyno the boat but i can tune the afr and ignition but not the vvti. I need to keep the cost low cause i have to buy two ecu to run both engine for my fishing boat. Thank you in advance for all your help.

Scott Posted May 23, 2016 Report Share Posted May 23, 2016 Hi Shark,If you are not going to run the VVT or e-throttle and are happy to run wasted spark and group fuel then the Atom will do the job for you. Be sure that the Atom also has sufficient inputs and outputs for things like fuel pump, engine fans, idle solenoid, TPS, MAP, ECT, IAT, etc. If you need more inputs and outputs then the G4+ Storm black is the better ECU to use.If you have an existing base-map for the 3UZFE with VVT, you can turn the VVT off in the base-map and retune the fuel and ignition to suit.Scott Quote Link to comment Share on other sites More sharing options...
Simon Posted May 24, 2016 Report Share Posted May 24, 2016 I would suggest the G4+ Storm as the best pick and it is the cheapest option to retain the VVTi.It will also do full sequential fuel and ignition. Quote Link to comment Share on other sites More sharing options...
