Good to know, I will order one up (although I'm hoping to find the cd/dvd version).
Found some interesting info over on automotiveforums.com, there was an explanation regarding VTEC's operation, now it wasn't about the R18A which is a reversal of the typical VTEC concept. It says...
"To make VTEC happen, the ECU has to realize the following parameters from the sensors on the motor:
1 Your MAP (Manifold Absolute Pressure) sensor must read 0hg (aka 0 inches of vacuum). When it reads this it will send a 3volt signal to the ECU.
2. Your throttle has to be open at least 50% because your TPS sensor has to send a 4.5-volt signal to the ECU.
3. Your coolant temp has to be at running temp.
4. Vehicle speed has to be above 20mph.
5. You have to have 65-80 oil psi.
6. The engine must be running at a minimum of 4500 RPM."
This is EXACTLY the kind of info I'm hoping to find for the R18A. So far, a few things that may be on the R18A's VTEC activation list may be...
- must be between 1000-3500RPM
- must not be accelerating or idle (i'm inferring this from the article about iVTEC on the R18A -->
Technical Overview of Honda's new R18 i-VTEC Implementation)
- maybe a positive MAP reading?? (just guessing almost randomly)
- throttle % would need to be extremely low as well
- engine warmed up
Any chance the service manual has such an explanation?
