Phillyc2003 Posted January 26, 2020 Report Share Posted January 26, 2020 I am fitting a rn setup into my 850 t5 (already 4.4 ECU) , the motor I am fitting has vvt on inlet and exhaust. I no Vast can do off narrow band lambda , but I am looking into other possible too. My question is: can I use the signal wire off my aem methanol controller? As it is setup to activate off min boost to max and is a voltage variable to a methanol pump (can I safely tap into that wiring or would circuit over load). I could well be way off on this but thought I would ask and see if anybody has done it or something different to get vvt working on a 4.4 setup. Has anyone used the 555timer options with any succes? I am looking at not being bound to the wideband mod to be able to run a usable vvt Also I have read only one cam is used for performance exhaust, and inlet is just for emissions ? Is that correct.

Tightmopedman9 Posted January 27, 2020 Report Share Posted January 27, 2020 You can just trigger the VVT on the intake side. Controlling the exhaust side VVT doesn't give much performance benefit. With dal independent VVT control you can increase overlap during spoolup which can help decrease spool time a bit Link to comment Share on other sites More sharing options...
