OFT and innovate supercharger

[kylem1853]

Does anyone know of or have any base maps for a innovate supercharger on the open flash tablet?

[SilverFoxBRZ]

Guess not. I've been sniffing around for a starting point too. If I can't get something lined up that I am comfortable with I may ditch the OFT and go with Innovate's supplied tune. My knowledge isn't as strong as I'd want it to be for starting cold on a tune like that.

I love OFT, but if I go with a kit turbo/SC that isn't either the electric SC or Vortech, it looks like I'll have to ditch it

You will want Ecutek anyway for the additional features and safety functions it has with boosted applications.

The only safety feature currently missing in the OFT is over boost fuel cut which only applies to turbo (not SC) applications. But I think this may no longer be the case soon. If also argue that having digital realtime gauges and alerts is useful too

Shiv, my loyalty remains as I have said before in some other threads. I'm looking forward to seeing what you guys do with Jackson's SC, Innovate SC, and maybe even a turbo kit...

No info to give at this time. But I am actively working on overboost protection in some form. I don't think it's going to be a very daunting task but it will take some time to get it implemented.

Please educate me on this (no sarcasm intended, I'm serious).
Fuel cut as overboost protection just seems wrong to me. You have a turbo pumping massive volumes of air into an engine and abruptly reduce the fuel. Isn't this a recipe for a horrifically lean condition? Wouldn't it make more sense to protect the engine by backing off timing and/or closing the throttle a little until the boost comes back in line?
I'm sure there's a piece of the puzzle I'm missing or don't understand. Can someone explain?

If there is zero fuel there is zero boom. Takes one revolution of the engine to evacuate the fuel so if the threshold is set low enough it's a very safe and immediate kill switch. At least that is how I picture it working.

I had a vision of it cutting off in mid spray. All it takes is one revolution to kiss a rod goodbye. I suppose properly executed fuel cut on a modern car would be done by simply not firing the injector on the next cycle, which would work the way you describe. I was thinking too old fashioned and envisioning literally stopping the supply somehow instead of simply disabling the injector between cycles.

I could be wrong . I'm just assuming that's how it would/ could be done. They may cut spark first or something too. I'm old school as well so was just kinda reasoning it out. I'm curious to know how exactly it's done too. I've never personally tuned anything more complicated than obd0 and carbs so I'm right there with ya . Just seems the simplest, safest explanation I can think of.

My understanding is that it stops injector pulses which does mean no fuel for the boom. Then you are just pumping air into the engine and even if you somehow manage to cram 200psi into the cylinders (say 50psi compressed via stroke to 200), it is still low enough for the engine to handle. Note, my pressure numbers were pulled from my ass and could be horrifically low... but it still isn't a problem.

Sorry to revive an old thread. However, I'm looking to pick up this kit from a member on here and currently have an oft. I would like to keep the OFT and run the kit with a OTS/Base tune until i can drive it down to a tuner. Just looking for any updated info on this combo.
