MarkR Posted November 19, 2009 Author Share Posted November 19, 2009 Ro has a Jspec head fitted so uses the Idle control valve. Before that i fitted a idle valve to the car to get more air when cold. Is fitting an idle valve an option on a vvti head? Quote Link to comment Share on other sites More sharing options...
Kopite Posted November 19, 2009 Share Posted November 19, 2009 Dimitri also fitted a stepper motor to my car when i was still VVTi but the idle was never right at that time so I can't say how helpful that was Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 19, 2009 Share Posted November 19, 2009 Motec M800 will work the stock VVTi seamlessly. I know, but am not really speaking to ( ) a VVti Supra owner with M800 working the DBW properly with all safety features still enabled. Ryan knows who it is If it were mine I'd fit a none VVti TB and adaptor, or early plenum, and get rid of all that *hit. I'd then run a normal, or a remote ICV. Job sorted.

Chris Wilson Posted November 19, 2009 Share Posted November 19, 2009 Is fitting an idle valve an option on a vvti head? Of course, it only has to bypass air around the main throttle plate. It can be remote mounted. Quote Link to comment Share on other sites More sharing options...

MarkR Posted November 22, 2009 Author Share Posted November 22, 2009 Does anyone know if there is a difference in the intake manifolds (airflow wise) from non-vvti to vvti. I'm thinking that if the DBW gives issues on Tuesday, I may just rip the intake side off and pop a non-vvti one on. Quote Link to comment Share on other sites More sharing options...
johnny g Posted November 22, 2009 Share Posted November 22, 2009 Interested to see how this progresses ... Quote Link to comment Share on other sites More sharing options...
MarkR Posted November 22, 2009 Author Share Posted November 22, 2009 Me too. I want to keep the VVTI but not too bothered about DBW. Hopefully the DBW works but if not I'll need to get my hands on an intake manifold with ICV and the TB from a non DBW version....

Chris Wilson Posted November 22, 2009 Share Posted November 22, 2009 I doubt there'll be any meaningful difference in air flow, and I'd definitely stick with an OE Toyota plenum. Quote Link to comment Share on other sites More sharing options...
michel lane Posted November 22, 2009 Share Posted November 22, 2009 The VVTi manifold is thinner then the stock TT, i would image the volume of air is less. As Kopite mentioned we just replaced the manifold with a stock unit and put a stock TB on it , wired up the ICV and its seems to work now after many hours of playing around with the AEMpro ecu.

sdistc Posted November 23, 2009 Share Posted November 23, 2009 Good thread. Mine has aftermarket intake manifold and throttlebody so the DBW was dumped, but it's good to know that it's possible to keep it. Quote Link to comment Share on other sites More sharing options...
johnny g Posted November 23, 2009 Share Posted November 23, 2009 I'm lining up a Solaris with Ryan for mine, but I fancy holding off to see if there's a 100% solution for this. Quote Link to comment Share on other sites More sharing options...

MarkR Posted November 27, 2009 Author Share Posted November 27, 2009 I don't really need it as my car is no more (see my build thread) but someone else may find it helpful. I also plan another vvti build so it would be great. Cheers bud. Quote Link to comment Share on other sites More sharing options...

Guest 98SZR Posted January 16, 2010 Share Posted January 16, 2010 (edited) Good thread. Mine has aftermarket intake manifold and throttlebody so the DBW was dumped, but it's good to know that it's possible to keep it. Andrew - I know you probably don't know as ESP done all the work but the vvti intake manifold has a different IAC (Idle air control) setup than the non-vvti (as it's electronic in the throttle body, as far as I'm aware) and I'm wondering what they used for idle control in your car with the aftermarket manifold. Back on topic - I know one solution is early model intake and TB but the Vipec V88 ECU allows the DBW system to work also, but you need to purchase an additional module. - Just another option - but not sure on support in UK. I'm going to ditch the vvti intake manifold as I have a hypertune manifold, only thing I need to do is figure out what to do with the IAC, might need to go aftermarket. Any suggestions?
