EK K24 studders just before VTEC

Post by aaron2003rose »

OK I not one to post questions but i can't find anything with my issues. So that car runs great and i am currently in the tuning stage my only issue is VTEC every time while drive the car will kinda studder/bog just before VTEC if i floor it it will kinda hit the wall and not rev past the point of before VTEC. Now if unplug the Solenoid I can drive no problem just no VTEC and the Solenoid is new with the pressure switch blocked off along with it in Kmanager.

The motor is stock internally, 550 injectors, Skunk2 Pro manifold and 70mm throttle body.
I have done a flush and changed the oil filter a few times and changed the TPS I don't know if I'm missing a ground or something also after one oil change it worked great then it sat over night and started doing the same thing.

You will need to post the calibration and a datalog showing the issue.
