Brazil Posted August 24, 2012 Share Posted August 24, 2012 (edited) Hi, Did the facelift VVTi model come in both FBW and DBW? I am asking because I believe I have the FBW set up as when I pull on the cable it accelerates.

EMPEROR Posted August 24, 2012 Share Posted August 24, 2012 Only DBW mate, but there is still a cable going to the throttle body, just not directly connected to the throttle butterfly (for the first 70-80%). Quote Link to comment Share on other sites More sharing options...

Do the guys change to FBW only so they can have a bigger throttle body & plenum? Quote Link to comment Share on other sites More sharing options...
Alex Posted August 24, 2012 Share Posted August 24, 2012 FBW? Fly-By-Wire vs DBW - Drive-By-Wire. It's the same thing!? The non VVT-i is cable operated throttle only with a separate idle control system VVT-i DBW has a cable to it to tell the electronics what you want by rotating a sensor, this is then relayed to the throttle control actuators via the ECU and in combination with the Knock, timing and cam position sensors to turn your command into reality or adjust it based on the data from the other sensors. It also controls the idle, thus eliminating Idle Control from the older models. DBW on the stock ECU is (like the MAF) limited to the OEM version only. If you require more that 600HP then you may want to change it to a larger throttle and lose these functions or try to retro fit another DBW system with a new ECU in both cases.

johnny g Posted August 25, 2012 Share Posted August 25, 2012 The DBW on the VVTi is the cable assisted. I chose to modify mine further by using a Corvette 90mm true DBW throttle body. Works flawlessy. Quote Link to comment Share on other sites More sharing options...

johnny g Posted August 25, 2012 Share Posted August 25, 2012 (edited) Yea. Well, it's what Steve bought. The car with DBW and the VVTi was very smooth, super light pedal. Very easy to drive. If I ever build another supra, that's what I'll do. All modern sports cars have DBW and VVTi. There must be a reason...

Brazil Posted October 25, 2012 Author Share Posted October 25, 2012 (edited) I bought a jun type plenum with a big throttle body 'from Parry', I intend in using a AEM V2 ecu what other components will I need to get this to work? On the throttle body there is a Toyota sensor I assume it's a none vvti fbw system sensor. My car is vvti.

tbourner Posted October 25, 2012 Share Posted October 25, 2012 Only DBW mate, I'm with Alex, what are you guys thinking DBW and FBW stand for? Quote Link to comment Share on other sites More sharing options...
