If you don't care about check engine lights, you can jump the Vtec solenoid so it's on constantly. Only thing about that with OBD-2b is that it might throw the ECU into limp mode (not taking input from other sensors, running on basic maps.)

On OBD-1 models, you can just put a jumper in the Vtec solenoid to run it all the time, and as long as it's not throwing the voltage back to the ECU, it won't activate the CEL.

Further on, with OBD-0 Vtec setups (one-wire Vtec modding) you could leave it active as long as you want, b/c the ECU doesn't check for Vtec solenoid signal, so it won't throw the CEL.(except the OBD-0 B16 engine)

Probably just random loose knowledge that doesn't apply, but there it is.

Consequently, I kinda wish I had OBD-1, so I could use the ScanGauge... I have a non-OBD car, so it's out of my reach... at least w/o a jumper harness and a new ECU.
