Crower Stg 2 at Vtec 4900-5500 cross over problem

Post by Hoggy »

Hi all,

Just got the Crower stg 2 cams installed and fired up with Hondata supplied map. My is a JDM with DCRH and V2. I lowered the ignition timing slightly due to high comp. Fuel map, vtec point 4900 - 5500 as per supplied.

When I hit vtec, the car jerked like got choked for 1-2 seconds and then high cam kicked in. Then it's ok from there but same problem in every gear at vtec points. Btw, the AF is kind of rich avg 11.5

I adjust vtec point to 5800 above... the car runs smoothly. Why it can't run with lower vtec, is it due to the cams or tuning?

Please advise.

Thanks!
