2012年10月24日 · But I can tell you.. The ECU will engage VTEC at that set RPM, regardless of the density of the air. That is irrelevant. VTEC takes: Oil Pressure, Throttle Position, and RPM into consideration, nothing else. A stock, GSR ECU will engage VTEC at 4,400 RPMs.

2003年4月30日 · Read this about VTEC and this about dyno tuning. Quote: MD's Dyno Tuning Basics Article 1. Find the Best VTEC Switchover Point First (if you have VTEC): Set the VTEC controller such that the VTEC switch is at 7000 rpm. The dyno pull will be done almost entirely on the non-VTEC lobes. Locate the highest rpm at which the hp dies on the non-VTEC lobe.

2010年3月14日 · VTEC - Variable valve Timing and lift Electronic Control. At low RPM, a VTEC engine uses a normal cam profile to retain a smooth idle, good fuel economy, and good low-end power delivery. The VTEC mechanism engages a high-lift, long-duration “race” cam profile at a set RPM value (i.e., ~5500RPM on the B16A) to increase high-end power delivery.

2009年11月11日 · No, that's not going to solve anything. The fuel and ignition maps (yes, multiple maps, high and low) have very specific values, which if aren't correct, can leave you sitting in a big pile of "you know what".
