any help? the car was supercharged. just got everything together and trailered it to the dyno and vtec doesnt work. everyting seems fine. the car runs great. oil pressure is great. things just dont add up.

 

Need more info, what turbo kit, how are you tuning, etc etc

 

basic custom kit. p-fabrications log style manifold, turbonetics t-70, aem ems

 

Is your tuner competent with an AEM EMS?


I ask this because it seems atleast 75%+ of turbo problems arise from tuners.

 

yeah hes done plenty of them

 

Couple things... How do you know its not going into Vtec? Is your tuner monitoring it thru the ems? What does he have the crossover point set at?
You had a comptech supercharger before, did something happen to the vtec solenoid when it was uninstalled and then reinstalled?

When my car doesn't go into vtec it hits a wall at 7k, can you run the car to redline?

 

In a turbo s2k (unlike s/c), vtec is not very pronounced. I don't even notice mine.

 

I can't tell when it turns on at all.

 

tried switching out the solenoid on the dyno still no luck. we put a jumper striaght to power and it would engage but only briefly. at the normal vtec point in rpms it just kinda falls on its face, and its obvious by the power numbers that vtec is not engaging

 

+2 cant even tell, once i hit 3.5K it just slaps the redline
