Throttle delay after OpenFlash
Hey Guys....quick question.
I recently pulled the trigger and finally went with the OpenFlash tablet for my tuning choice. First off, I love the way the car feels now, truly a great job and worth every penny. The flashing process was simple and I didn't run into any issues. With that said, I'm having one small issue with the throttle delay not really going away as it normally should. I flashed my car last Friday (4/4) to the stage 1 tune. I know that the throttle delay is to be expected any time the ECU gets flashed, however from what I've read about other people's experiences it seems to go away fairly quickly. Each time before I start the car I've been putting it into accessory mode and pressing the pedal fully down and fully releasing about 10 times then turning it back off before starting the actual engine. Additionally I've taken it on a few country back roads and let it briefly hit redline to see if that helps. Despite this the delay is still there, not better or worse, just not going away. Did anyone else ever experience it taking a longer time than this? Just FYI, it's my daily. |

Accessory mode does nothing. You need to have the key set to ON without the engine running. If you have keyless start, that's 2 presses of the Start button without stepping on the clutch.

Don't worry it will go away after a week or so of daily driving. I've noticed this too, even after doing the "pedal thing" with key set to ON. In my case, I've noticed that for some reason after flashing a new map, the gas pedal has a very slight dead spot where you could depress it the first few millimeters and get no revs. But apart from that everything else works as normal. More of a minor annoyance than anything

It will go away in a few drive cycles. Give it a day or two for the ECU to learn the new min and max throttle voltages. This will need to be done after every flash or ECU reset (battery disconnect). |

There's the dead pedal curable by the pedal stuff. If you've done that then the trims being set at low RPM and idle will settle after a short period and get rid of that.

Dang. I flashed mine on Tuesday and was hoping it would go away in a couple days like some people said. Guess I'll give it a week also. I think the pedal thing only works RIGHT after you flash it?

The "pedal thing" helps, but it isn't a complete solution. I'm a process engineer and one of the things I do is tune control loops. What it feels like to me is that the control loop between pedal and throttle isn't tuned correctly after the flash, leading to a lot of herky-jerky shit. This goes away over about a half dozen drive cycles for me (average drive is about 30 miles). It's annoying, yes, especially to someone like me to likes to make a lot of small tweaks.

Personally, I just flashed and let the car idle for a 3 or 4 min, then took it out for a spin. Did a few runs from minimal throttle + rpm to max throttle and rpm through the gears and was fine/unnoticeable to me

My experience has been the same, but in some cases much longer than one week. I may have noticed some correlation to ambient temperature, but I have not confirmed this. Keep in mind that I may be finding correlation where there isn't any.
First flash (November 2013)->almost four weeks of daily driving and several hour long drives and the pedal still had some deadband at the end of that Second flash (December 2013) -> the usual deadband which tightened up after a few drives but was instantly gone within a day when the temperatures exceeded 0C. Third flash (January 2014)-> the deadband remained for two weeks until the temperature exceeded 0C for two days Fourth flash (March 2014)-> flashed on a day with >0C temperatures, but the following two weeks were colder, the deadband did not disappear completely until the temperatures rose well above 0C In all cases I drove to work daily and often did lots of other driving, certainly more than a dozen drive cycles a week. Has anybody else noticed a bit more time to learn pedal scaling during winter vs. summer? Could this be a scaling routine not yet found in the ROM? |

Same issue here and nothing seems to work, other than actually driving her around for a few days. Yes I did pump the throttle with the dashboard lit up.

Right now I'm running just the stage 1 tune for premium fuel, E85 isn't easy to get here where I'm at right now. However I've got nothing but good things to say about the stage1 tune. The whole car feels much butter and pulls harder...really changes the whole character of the car. Plus, I believe Shiv said that soon the tunes will be differentiated between 91 and 93 octane for the folks who still just use stage 1 but can get better than 91 in their area. |

Just to clarify, there is no such thing as an E85 Ecutek OFT. Ecutek is another tuning company that sells another tuning option which requires a laptop, software license, security dongle and cable. The OFT (OpenFlash Tablet) is something else entirely. If you haven't already, visit www.openflashtablet.com for more information or please email sales@vishnutunining.com if you have any questions in particular. Although I'm sure you can get answers on the forum since there are several hundred helpful OFT users who actively post in this forum. Of course, I'll try to help as well
