Osiris as Launch Control or two step rev limiter!
I went to the local 1/8 mile track last night and tonight to practice. The thing is, I was wondering if I could use the multi-map feature of Osiris as a two step rev limiter or some kind of launch control aid. Guess what? It works!
I'm able to hold the gas pedal down to the floor with the RPMs at a preset 3500rpm, and the only thing you have to worry about is let go of the cruise control set/coast button as soon as you let go of the clutch and the ECU will switch to the performance map or whatever map you selected before in a split second and off you go. This is good for consistent launches.
I don't know if Uprev had this in mind when they designed the multi-map feature, but this is an awesome feature I discovered by mistake. I'm into drag racing, so I find good use to this. I hope that those that bought Osiris, like this as much as I did.

I didn't think you could swap maps above a set RPM range... I thought it was 1600 RPM.
Why not just rev the motor to 3500 and let the clutch out?

I agree with your last statement. I've never had an issue controlling my revs. I just aim and fire

I can switch maps at any RPM, load or speed. It's not a problem. Plus I like the sound of a two step limiter.

If using valet mode to launch your G works for you... do it!

Launch control does sound cool tho...

Cipher is a great tool and comes free with Osiris. A lot of people seem to forget about Cipher, but it's a great tool in its own right.
