No Vtec engagement.

Post by NL_22 »

07 6spMT Acura TSX
JDM k24 3 lobe swap
Flashpro current 3.5.3.0
Short ram intake, header, exhaust

Tune the low cam and everything is working fine. VTC operation is also working fine as well. When commanding 0,10,20, it showed each degree on the data display. Set upper and lower to 3000rpm and vtec pressure window at .118bar across to start tuning the high cam. Drove vehicle up to 3500rpm but notice that the VTS is not turning on. Tried re-uploading map but still the same. Checked connections at the vtec solenoid all are good. Checked oil level and that is fine as well. Calibration is attached.
