justin sue Posted December 21, 2010 Report Share Posted December 21, 2010 is it possible to have quad vvt control and electronic throttle control via a e-throttle module with a xtreme? i got one of the later xtreme ecu's (red) with out the e-throttle control built in and a quad vvt engine. the 4 vvt oil control valves need to be wired into aux 1-4 but signal 1 for the e-throttle module needs to be wired into either aux1,2,3 or 4. can signal 1 for the e-throttle module be wired into a different aux channel?

Jurgen Biggelaar Posted December 21, 2010 Report Share Posted December 21, 2010 This is a limitation. You can either have one or the other at this time, you're not going nuts... Your investigation is dead on. Jurgen Quote Link to comment Share on other sites More sharing options...
lemmy01 Posted December 28, 2010 Report Share Posted December 28, 2010 Hi, i think this is for a v6 2grfe toyota engine? why 4 aux? it should be possible to only use two aux. It is not neccesary to have different settings for each bank. So it could be a option to put two valves on one aux. (left-inlet/right inlet and left-outlet/right-outlet) Ralf Quote Link to comment Share on other sites More sharing options...
justin sue Posted December 28, 2010 Author Report Share Posted December 28, 2010 yea its for a 2grfe. it should be possible to double up on the control valve aux channels but any differences between the banks like oil pressure or wear on the parts would produce a slightly different offset in the cam angle. would be best to let each cam dial itself into the target angle itself i would think.

lemmy01 Posted December 28, 2010 Report Share Posted December 28, 2010 Look here. (must scroll down a little bit) There is a article that thor-racing(link dealer) have done a 2grfe with linkg4 extreme (vvti and dbw). So it should be possible without some bad tricks.

lemmy01 Posted December 28, 2010 Report Share Posted December 28, 2010 sorry bad link. here is the right one Quote Link to comment Share on other sites More sharing options...
justin sue Posted December 29, 2010 Author Report Share Posted December 29, 2010 yea thats running the older version of the link xtreme with the inbuilt dbw capabilities, I have the later version and a E-throttle module add on. Quote Link to comment Share on other sites More sharing options...
lemmy01 Posted January 3, 2011 Report Share Posted January 3, 2011 Thats very bad news. I don't understand the reason why the new version of the g4 extreme have that limitation. It make no sense to me to convert a DBW Engine back to mechanical-throttleblade. So it could not control the 2grfe and i have to look for a other ecu for my 2grfe project. Thank you for the info.

Jurgen Biggelaar Posted January 13, 2011 Report Share Posted January 13, 2011 Hi Ralf. After some market research, we discovered that roughly only 1% of the sales made on the original Xtreme were using E-Throttle function, this allowed us to remove these functions (which are quite costly) and offer them in an external module for those that needed it, and make the unit a lot cheaper for everyone else.
