If it doesn't improve I'll try that when the OTS v2.0 maps roll out. I'll be away from my car for a week and a half anyway.

Hmm, takes up to a week... Ok, I'm just impatient. I see no reason for the ECU to take that long to learn the throttle pedal calibration, but I'm assuming it's a safety thing.

I do the procedure I outlined above as well as allow the car to idle until the revs drop after the first start and I don't get any throttle pedal delay. I did this when I had Ecutek and now with OFT and it works. It's been outlined in other threads as well.

wont take a week :-)

see post below for some tips, the ecu needs to find the throttle zero position after a reset or reflash, if you mess with throttle before its sorted itself out it can take a few drive cycles to sort itself out, same thing can happen with cam actuators, after reflash basicly turn ignition on leave for 20 sec start let idle for a minute at least, see post for details

I've tried all the tricks and I find it still takes over 3 weeks for mine to sort itself out. The biggest improvement is in the first 4 days/100km or so I find, where it goes from 1/3" of deadband to 1/8". Then it just takes time for that last few mm to sort out. I wonder if my TPS is more out of tolerance than most which is why it takes longer to learn.

Might be worth having a look at your ltft long term fuel trim arount idle and low rpm and see if it high, if si you might benifit from scaling maf or check for exhaust or intake leaks

I have this same issue, I am at about 2 weeks after a reset and I still have that slight amount of dead zone. what should LTFT be at idle? I just ran a log yesterday and mine is -7.81.

Thats pretty normal for unscaled maf, if it was over 10 you would be looking for leaks or scaling maf.
Does tend to vary at idle due wide variation in iat temps.

Also have a look at your IAM if its way below 1 the reduction in advance can make the car feel sluggish

Does seem strange thet some guys get the throttle dead spot for so long, never been a problem for me since letting car idle after imediatly after flash .

out of ideas now

[Target70]

thanks for the help

If IAM is the same thing as ADV multiplier(I haven't been able to figure that out) then It is a solid 1.

The dead zone isn't much of a problem, It just keeps me from wanting to change tunes very often. I have the OFH coming hopefully end of the month, so I am going to wait on v1.6 until I can flash to stg 2 v1.6.

I found the dead throttle dissapeared quicker after my first attempt at MAF scaling. I suspect the throttle pedal takes a little time to learn but the fuel trims being out also account for some of the doughyness we feel after a flash.

yes IAM is ignition advance multiplier

I'm the same way, I don't want to flash and try new things because of this. It is a royal bitch to drive for a week before the car feels ok, especially in the winter when traction is limited.

I'll look into the LTFT, but I know that looking at the Throttle Pedal position vs. Throttle position in realtime on the tablet, the pedal position stays at 0% for several millimeters of pedal movement. As soon as it goes to 1%, the throttle position increments and the rpms increase.

Then you need to do the accelerator pedal calibration:
- Car on, but not started
- Fully depress and release the pedal 10 times
- Start car


You can do that at any time, not just after a flash. So if you feel like you're still experiencing "lag" then just give that a go. There is, however, always a small area of the pedal that doesn't register and that is normal. It is also true that trims can have a decent impact on feel too.

just got mine so I'm joining the conversation...flashed my basically stock (TRD cat-back) car and within 10 minutes I was like
wooooooo


I like this thing...
