Openflash Tablet v1.31 beta maps (including Stage 2!) now available for download

Agreed.. Flashed 1.33 and felt the typical squishy pedal and awful shift timing.. All will pass after 50 miles

It is a strong possibility that perhaps my car has not had time to read the ecu but I drove about 20 miles total.. to and from work. I tried to open her up a few times just so the car could experience it and learn.

I dont know what is going on between 1k to 2k but it is not a smooth rev and almost bucks slightly.

If the newest beta tune 1.33 is safer than the prior then I will accept that.. did they reduce the timing or something? if its not safer at all and the prior beta is just as safe then I may flash back.

thoughts? ill give it another commute to work.

You can so a file comparison between the two map versions. I think you will see nothing that explains what you are feeling as the mapping is not very different. Perhaps you just need to let your car adapt after the flash?

Considering Shiv has the car, I would say the latest and greatest will usually have most the intended changes wanted to be made. I can't feel a huge difference between the two files yet, however that doesn't mean the file itself isn't better mapped/tuned for future improvements.

We are lucky that we get new candy each week while everything gets sorted out and perfected. Imagine the grins on our faces when E85 and the electric supercharger are tuned together with OFT..

After a flash, you NEED to let the car idle for a 45-60 seconds. If you drive away immediately, VVT will be disabled and the engine will feel laggy and unresponsive. Exactly how garful described. It will eventually wake up after some driving but during that time it will suck. It's pretty obvious when this happens. Best to just let it idle for a bit after for flash. Do not press the throttle at all during this process.

I take everything I said back. I am loving 1.33b! My car has woken up. I am not sure why there is such a drastic increase in performance between 1.31b and 1.33b but i am not complaining lol. I think more has changed from A00C to A01C than we realize...

Knock sensors are notoriously inefficient at high RPM, so there's not much point.

Why don't you get rid of the dead pedal before you drive it away!?

What map does your car take? A00, A01, etc?

What is the exact procedure for this? Ive tried a couple key on, gas mash, key off routines that were posted without success..

Turn on car, don't start engine. Depress and release gas pedal 10-20 times. Turn off car. Start car as usual.

^^^ This. My original magic figure I was given was, for some reason, 7. I always do 10. Must be depressed and released fully. That's why it takes a while when you drive, think about how often you fully take your foot off the pedal AND floor it in any one given drive cycle

How does pressing and releasing the gas pedal when the car is off help the ecu to learn? I was under the impression the car uses an analysis of exhaust fumes to determine calibration. What am i overlooking?

When the key is ON, the ecu is ON.

What is the time sequence of all these steps? I know some cars have time requirements with throttle relearn procedures.. The steps above didnt work for me this go around when I flashed (my throttle already corrected so this would be good to test for the next flash)..
