Thread: VVL Activation via TunerCode (Stock DE ECU)

so if anyone wants big cam idle and the low end performance of the small cams, I have figured out how to wire up a couple of "normally closed" relays by using two ECU ground points from the NEMU powered ECU.. This will go from big cam at idle til 1750 RPM, then to small cams, then at 4750 RPM it will revert back to the big cams.



If you want to add in a switch that would revert back to a smoother idle for those days when you're not feeling like big-cam idle.. you can add a toggle switch.. this took me 5 minutes to come up with the idea.. another 45 minutes to put it in MS Paint..

I will have to put on my 9th Grade Electrical Engineer Thinking Cap again to pinpoint the best place to put a toggle switch to keep a smooth idle and still hit VVL at 4750 (or whatever point you want to switch to big cams)

sounds like a waste of time and gas, not tryin to diss.

try harder

Will this work the same with the Nismotronic SA version?

josh, its hella simple dude... either use your o2 heater wire, or one of the other ones.. then you just goto nismotronic outputs section an set it up..

12v key on power to one half the solenoids, then negative being one of your ecu outputs.. when everything you set in the program has been met, it gets grounded, BOOM VVL SON!

oh i reread the thread, that shits dumb like i said the first time.

if u want vvl activated an shit normally just follow what i already said.

Thanks Josh, Im trying to help someone find their EGR wire to use that and not the A/C wire.

what i like to do is take a test light or multimeter and hook the + to the + on the battery then the - into the wires im testing, you can set the vvl on point real low like 1500 on 1300 off so when u blip the throttle the light will turn on, or multimeter will show volts an stuff..

I was going through my program and its been updated since this thread has been made. I am not 100 percent sure I am doing this correct. I was trying to follow what was posted in the picture.

If you are using the NismoTronicSA software then you will want to go to OUTPUTS -> GENERAL OUTPUTS and then pick the output you want to use from the drop down an then select the parameters you want to use for activation (RPM, TPS, ECT).

Here is an example of using the nitrous section to control an output, it is the same idea on all of the general output programming.
