Id love a tune that can change, at the very least the shifting. Ive read enough about those throttle controllers to know that I'm probably not interested one. I would just love to change how slow my car downshifts. I was trying to make a light and floored it and it felt like forever before it downshifted.....Like 10 minutes

Ah I see. Thanks for the link

That dyno graph is focusing on peak power and torque only and honestly... it's a 6whp shame.

Otherwise, that graph is identical. You're better off saving your hard earned money

Yea I will save my money . Another deal breaker is the fact that I have to mail my ecu to them and wait for them to tune it and mail back.

from my correspondence with them, their tune is geared more towards maintaining the "updated" calibration when you do mods, i.e. headers and intake. Apparently the ECUs in these cars will adapt and scale back timing/fuel advance/etc when you add power adders, so you'll get 6HP from the chip alone, but it will prevent the car from retarding timing et al when you start moding. I hope to be able to save enough for Novel headers, a CF intake and then install this chip. That should be good for about 25-30 whp based on what some videos have shown.
Plus that orgasmic novel sound...

That's funny
Basically , they're saying that all the 1000s of dollars of mods on your cars will reduce performance... and we will.... for a modest 500 bucks ... stop that from happening and give u 6hp bonus

lol

That dyno graph contradicts everything they suggest

texaslexii

I think what they mean is that when you put full exhaust and intake, the car will retard/detune itself. This chip allows you to retain the 20 or whatever gains you get from those mods, plus an additional 6 from them.

That's not what their dyno graph is showing.

And the hidden truth is.... they have not yet cracked the GSF ECU.
RCF yes, but not the GSF yet.

The GSF tune improves mid range torque... That is what i have been told...

DONT except any HP gain with the tune...

texaslexii

I agree with you on their sheets, doesnt make a whole lot of sense. However, supposedly they dont mess around with a lot of parameters for fear of running into bad fuel and causing detonation/preignition et al. I just wonder if the whole "we keep the ECU from reverting to stock if you mod" thing is true or just marketing.

Truth be told I am finding it less and less convincing and difficult to justify its purchase.

Let me chime in here to clear up some mis-information.

(1) We can tune 2016 GSF ECU.... no one can tune the 17+ ECU yet.
(2) The tune provides a noticeable improvement in mid range torque, we have many satisfied RCF customers who can attest to this. If you are guided only buy peak power gains, then you are out of luck.
(3) The tune ensures you don't get a check engine light if you install catless race headers (not applicable to street vehicles, race vehicles only).
(4) The tune removes the speed limiter.
(5) When customers send us the ECU for programming, we return ship the ECU ***SAME DAY*** so the wait is minimal.


FYI, the Takeda RCF/GSF intake makes ZERO power and is a complete waste of money... we have tested it extensively and I can make this statement with absolute confidence. We don't sell an intake for this very reason, they don't make any power. HOWEVER, in the next month or so, we will be introducing a very nice intake related product that actually does make your car faster... coming soon

That is what everyone is waiting for!

Are you expecting to release a handheld?
