how much will your ecu advance the timing on an h22 when you engage vtec. from the factory. i know that you set the normal timing at 16 degrees but i want to know how many degrees it will advance it when you hit vtec.

 

Should ask the tuning forum regarding general base map specs. Your ignition timing lead will vary with the throttle posistion and load, reguarding WOT/full load timing I would think 98Vtec should know.
