Osiris Tuner now available!
Basically yes. People keep asking for a base tune to build from and it's not a great idea. Start from the stock ROM and go from there.
The reason Tuners use a base tune on aftermarket stand alone ECUs is because they need to be able to make the car start, etc. The stock ROM already has that stuff in it, so theres no need for that with our system.

its gonna be really nice and easy to Retard timing correct on a FI car.
allso, engine respond gonna be much much faster and smoother.
By the way is timing VS KPA or MAF
i used to tune some LS1 engines using HP tune and i like the way it is
wow..... im dieing to see the stock timing map !!!

great product guys.
i am still operating on the beta version, i recently have been reading over my old info and have noticed there is a users guide.
i am not seeing this anywhere. i have run the installer a few times to see if i missed it, but i do not see it. there is no users guide in my uprev folder
do i need to "upgrade" my beta version to the regular version or am i just that blind?

MAF only reads to 5v per spec. Thats why the Modified MAF needs recalibration.
We provide a basic curve to start from when using the stock tube and Modified MAF with Osiris Tuner. You can adjust from there if you need to, or you can use an alternative MAF/tube and use our software to recalibrate it.
We just wanted an easy solution for our customers, something that works well, is reliable, and simple to duplicate.

psi does not equal hp, psi does not equal air flow, so it depends on the vehicle and application as to when the MAF runs out.
Which is why we have them available, if you need them, they have been made.
Yeah my MAF also get maxed out past 4800rpm.. STS has a small turbo at it's just rated 50lbs/min which is the smallest out there for our car and my MAF also get maxed out after 4800rpm.
Look at this first gear pull and my MAF is already maxed out at 4psi and 5500rpm.
Now look at higher loading gear like 5th gear and I max out even sooner... 5psi and 3300rpm..
