^^^^^^Larger Throttle body/Different Cams/ Re-worked headers/ etch......... The version in the RCF just breathes a lot better stock. There was a list somewhere that listed everything that they did to the motor and what I put was just a small fraction of what they did to obtain the increase in power for the RCF/GSF
Good to know. Thanks for clarifying that. I'm going to rip apart my ISF over the summer and put some modified parts in my engine to beat those numbers. Then the Greddy supercharger goes on.
This really is probably the most important development for the F family since 2008! Hopefully this will stop others from leaving their F's in the quest for more power elsewhere. I for one will be getting the remap done at some point, followed by the supercharger kit when it's finished.
Thank you for your hard work and perceiverance where others failed. Your contributions to the forum and the F have been amazing in such a relatively short time. We are incredibly lucky to have you guys pushing the boundaries for us.
Look forward to seeing more results in due course guys.
This is such great news! How fortunate we are to have you guys taking the time and dedicating the resources to solving this puzzle for the community. I can't wait to see how the gains net out with I/H/E cars, but I'm sold either way! Congratulations on the success for your hard work!
Can I still pass smog with the tune? Would anyone know?
If you still have cats - you'll pass smog.
For those who do not have cats, and also do not have simulators - the CELs for catalyst efficiency are disabled. The version currently on Rafi's ISF has these disabled for testing of the readiness monitors.
Is there (or will there) be a tune available for a fully stock vehicle? I am assuming the maf scale may be different for an intake equipped car like yours?
Awesome news & kudos for the commitment & dedication.
Now to the point, would you be able to tune an AUDM (Australian spec ECU) &/or a JDM ECU?
Will you be able to factor for various mods? I have a PPE headers, Borla cat-back (high flow cats), Injen intake & a ported intake manifold/throttle body.
I hope you respond back with a yes.....
Secondly, I assume you'll raise the rev limit? To what limit will you be comfortable considering stock internals?
Thirdly, would this pave the way to you developing & introducing a camshaft upgrade for those who don't wish to go down the SC/turbo route?
I'm not a tuner by any means and absolutely not an expert or even have the slightest understanding on how much work and the difficulty that when into this. Please correct me if I'm wrong but from what I see, there is a huge sacrifice in power at the low end to achieve 40 horse at the high end. I can see a drop of about 150 HP for several RPM. Am I seeing this correctly?

You're crossing the torque and hp lines - this picked up HP and TQ at every RPM. Pic shows - same mph and rpm...

Reason: adding pic
I'll second this. Given the easy availabilty of 97 and 99 ron fuel here in the UK will there be a big difference in results if using either? What octane was your test car running?
Cheers
98 ROM in Europe is equivalent to 93 R+M US-spec gas. I've tuned many cars on euro premioum gas, its the same thing.

I know I asked this before.... any plans on doing a E85 tune?
Here is a 5.2L GT350 stock, tuned, and tuned on e85
The stock GT350 fuel system is big enough for e85.
Hey Juan.... its very tempting to try. Downsides here are that we cannot add flex-fuel sensor capability, so you would absolutely be locked into using e85 or not drive the car.
We will be back on the dyno tomorrow with some Torco Accelerator race gas additive. I think this would be a practical alternative, and should yield some gains given that our ignition maps have more headroom than stock for additional power gains... we shall see!
