If you are still under warranty, it is free. If not, expect to pay hourly rates. They may just charge you an hour labor for that, which at my dealer is around $125 an hour.

Dealers may even charge for more than an hour, so be prepared to pay exorbitant fees. The new ecu flash is not worth it.

 

Did you get it? Tell me about it.

 

I personally did not get it because of all the other members on here saying that it makes the throttle less sensitive and will smooth out the acceleration. However, this will make your car slower when accelerating from stop. I do not want my car accelerate slower. Plus it may be very difficult to revert back to original flash once you apply this new one. Unless you absolutely hate that your car accelerates too quickly from stop, then I would advise not to do it.

You will experience less jerkiness from accelerating, because it won't accelerate as fast from stop. You can search on google and this forum about the ecu flash. Some people hate it, some people love it. It all depends on what you like.

 

Sounds great then. Cause it's my mom and Dad's car and they f'n hate that part about the car. I didn't care for it either, too abrupt, never felt that in any car I've driven. And I currently have a 370Z.

 

LOL

It doesn't make your car slower.

It just keeps the throttle from being too sensitive. Makes your acceleration EASIER to control.

However after done, it's still quite sensitive. People still chirp the tires on accident the first time they drive it.

The difference is how far you have to push the pedal down. It just gives you more control.

I'd also imagine a side effect would be slightly better fuel economy since it'll be easier to control the throttle while part throttle accelerating and while cruising.

Trust me, I'm a horsepower junkie (last car was a 450hp trans am than ran low 12's in the 1/4 as a daily driver). I did this like 6 years ago and never regretted it once.

 

Ok my dad just got it done for $152 at dealer. He's finally satisfied. He always said there was a dead spot initially, then all of a sudden boom you're gone. I felt it too, not a smooth gradual pull. But he says now the idle is like 600RPM.

 

With the ecu reset, your computer is relearning everything (including idle).

 

Exactly. It will make your car slower if you push down the pedal as much as you did before the update.

You will have to push down differently to achieve the same effect.

 

Who drives like that?

How far you push the gas pedal is based on how the car responds, not some "push the pedal this far" foot muscle memory whatever.

The issue with the overly sensitive throttle before the reflash is that the throttle input and throttle response are NOT linear.

These aren't the real numbers, but more like how it felt.

before flash: push pedal 10% down and you get 25% throttle
after flash: push pedal 10% down and you get 20% throttle, push 15% and get 25%


The difference is SLIGHT but it keeps you from accidentally chirping the tires, etc. If you want 25% throttle, it's not exactly hard to push the pedal slightly farther. You will not end up feeling the car is any slower or any less responsive.

I think the only way you'd understand is driving a car before and after the flash.
