111R 2nd Cam Question

[aussiebeano]

when I bought my 111R 6 weeks ago, the salesman said that once on 2nd cam, change up a gear and the 2nd cam will stay on for 2 seconds to give a chance of getting the next gear engaged without risk of dropping off the 2nd cam. Reading the forum and driving experience are telling me otherwise - I still get the 2nd cam surge on the newly selected gear. Am I being told porkies?

Before anyone asks, yes - I do plan to remap and lower the 6200 to 5500 rpm for 2nd cam kick in. Will do that after the HID lights, hurricane induction, 2bular exhaust, etc....

I've never heard of a "2 second timer" before. It's all revs dependant. There are mechanical restrictions as to why the 2nd cam isn't engaged at lower revs AFAIK.

On stock ECU:
2nd cam turns ON at ~6000-6200rpm
2nd cam turns OFF at ~5700rpm

On motorsport ECU
2nd cam turns ON at ~5700rpm
2nd cam turns OFF at ~5700rpm

That's my understanding anyway.

I like to use the second cam as much as possible, and in my experience, unless you pretty much reach the rev limiter in each gear (remember that it's a different value depending on the gear selected), you'll have a difficult job keeping in 'the zone' after each change up. It can be done, of course, but I don't think you've got anywhere near two seconds to change gear - the revs would drop by a significent amount in that time.

Total cobblers as far as I'm aware. Personally I'd go for the remap before all that other stuff.

AFAIK, it's 2 seconds that the ECU lets you rev up over 8000 rpm (but max 8500rpm) before cutting in the rev limiter. That's why you'll get to about 8500 rpm in 1st and 2nd gear and less in higher gears.
