going with Ruben from Dynocenter. Hope to have him back soon (according to him he'll be back on 13 of january) in the island after his shop got torn apart by Hurricane Maria. I'll post back with number once all of it is said and done.

I have successfully installed my Ace header and front pipe, and flashed my car with the CSG Delicious tune, and it's amazing. There's so much power up top. There's no immediate acceleration from a stop, but up top, holy cow.

The pedal range is so much wider on the tune than from stock, so initially, what I thought would be WOT was actually just 30% throttle or something. I initially thought the tune was way wrong, or something was off, because I wasn't pressing the pedal far enough to give any significant amount of gas to the car. Haha, a little embarrassing, but I'm glad I learned, because the car just goes now.

There's a club dyno day coming up, so I'll post results after that happens.

Hi, can you explain what you meant by the pedal range change? Does the delicious tune change the throttle pedal response/scaling? Also does it have an impact on the throttle delay (increased/decreased, or no impact)?
Thanks

With Ecutek when you flash the vehicle the gas pedal has to relearn positioning basically but usually after the first 15 minutes you should be good to go. So right after you flash you will notice that you're having to use more gas to get the same effect before the tune, it's not permanent and it goes away.

Thanks, usefull to know.
Do you know if the same thing happens when you unplug the battery?

[Trueweltall]

I'm not too sure about that, I have yet to unplug mine.

Just an FYI - you can recalibrate the drive-by-wire accelerator pedal sensor by putting the ignition switch in the on position without the car running and slowing cycling the accelerator pedal through its full range of motion 20 times. This essentially forces the ECU to go through a re-learn throttle sequence.

Any time ecu is flashedwith new tune, with any tune system ecutek tactrix oft kess it will reset all the ecu learned parameters in RAM memory, same thing happens if the power is completly removed from ecu ie battery terminal removed. Their is a whole bunch of stuff learned like fuel trims knock control, throttle calibration cam calibration.

Its important to let the car idle for a least a minute after reflash\reset to let ecu do its thing, the ecu continuously learnes and adjysts these parameters, you just notice it more during the initial phase as everyting was set to default

The pedal position has nothing to do with the time after flashing the tune in the case I'm talking about. The tune has the pedal position set up to be at WOT at 80.4% pedal position. The stock tune is WOT something around 40%. Having a wide pedal range makes it easier to be more precise with the gas. I'm actually liking it more and more every time I drive the car.

Throttle delay would only be caused by the driver not slamming the pedal to the floor fast enough. After getting used to the full range of the pedal, this is no longer a problem. I can give it precisely as much gas as I want, when I want.

This is how our cars should be. You need to have a motive to rev this engine.

Maybe with the 2017 the pedal scaling is different, because I verified that with the Torque app, and for the electronic throttle body to be 100% open, the pedal need to be physically around 90%. The 90% is an approximation of pedal travel before hitting the stopper, because when the pedal is on the stopper, there is still a lot of travel left (I saw that when I removed the pedal to installed a spacer).

Hmmm, interesting. I don't know about the '17s. I have a '15, and the info I shared was the info Delicious shared with me. If you're pedal needs to be at 90% to be WOT, then I imagine the pedal scaling on the tune will feel right at home.

Oh, I have a motive now, and it's addicting.

It varies with RPM. However 40% is an exaggeration, actual WOT won't be achieved until ~85% pedal. That's me just looking up the pedal mapping. However it's definitely not linear and at lower RPM you get more throttle angle per pedal degree.
