JMB Posted November 7, 2011 Share Posted November 7, 2011 Hi all, I received my specific ssqv III and in the manual it is say That it can create rich conditions with some engines. How about with the 2jzgte (vvti) ? Thanks, Quote Link to comment Share on other sites More sharing options...
Scott Posted November 7, 2011 Share Posted November 7, 2011 The rich conditions are caused by MAF sensors. I could be wrong but I think the VVTi does in fact have a MAF so you will most likely get rich spots when lifting off etc, basically any time the BOV is vented to atmosphere, as the air that would be going through the engine (that the ECU has calculated the fuel for) will now be vented to atmosphere leaving too much fuel for too little air. I don't think it's much to worry about in the Supra though. It might get a little grumpy when changing gear at low RPM but I don't think it would be highly noticeable.

Nic Posted November 8, 2011 Share Posted November 8, 2011 HKS do a recirculation kit for the SSQV, recirculating the air would ensure you do not get any fueling issues but it'd make the BOV virtually silent. Quote Link to comment Share on other sites More sharing options...
Westy Posted November 8, 2011 Share Posted November 8, 2011 Stick with the stock item in the VVTi mate. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted November 8, 2011 Share Posted November 8, 2011 Yup as above, recirc valves for MAF equipped cars. Quote Link to comment Share on other sites More sharing options...
JMB Posted November 8, 2011 Author Share Posted November 8, 2011 That s too bad... Wich to have the famous "pchhhhit" of the bov I ll wait to have my AFR gauge installed before installing the bov so i ll control if the rich condition is That important ...

Scott Posted November 8, 2011 Share Posted November 8, 2011 The UKs don't have any issues running BOVs so I doubt the VVTi's will. You may get a little hunt dropping to idle and stuff like that but nothing to worry about IMO. My MR2 ran like a bag of spanners with one, that was a different kettle of hamsters though. If you get the full kit for the MKIV they come with the recirc fitting anyway so if you got it, and decided you didn't like it, you could always fit the recirc valve.

Guigsy Posted November 8, 2011 Share Posted November 8, 2011 My uk ran fine with a vented one which has the same sensor Quote Link to comment Share on other sites More sharing options...

I agree with ScottM, go for it and enjoy the 'pchsssssssssstttt' I have the SSQV with a MAF (Netherlands) on my Supra for about 3 years and the cars runs great. I would say the bigger IC + higher boost (1.3bar) and the stock ECU trying to compensate for these conditions make the Supra the run very rich at WOT, more then a BOV could "accomplish". my 2 eurocents Edited November 9, 2011 by boomstick (see edit history) Quote Link to comment Share on other sites More sharing options...
