Turn ignition to on (not start) for 60 seconds then off for 5 seconds then back on for 15 seconds - if you have the engine lid open you can hear the throttle readjusting. I do this about every quarter. Do this if you feel your throttle is sluggish or not as responsive as it maybe once was.

 

What does this procedure actually do?

 

resets throttle-by-wire mapping so throttle response becomes sharper as this can become sluggish at times

Do we have to press anything or do anything else apart from leave the ignition on and off?

I tried your mentioned procedure but couldn't hear nothing in the engine bay and can't seem to notice the difference unless am doing something wrong?

thanks

 

Sorry for the late response...nothing else is needed. When I do this I can hear the throttle body adjusting (motor sound) when the engine lid is up.

 

I did this right after installing the IPD plenum and throttle body. It calibrates the throttle so it's properly mapped regarding, fully closed to wide open and every point in between.

With the engine bay open I definitely heard what sounded like an electronic whine as the throttle was calibrating itself.

 

I have the opposite problem..mine is simply too responsive, even on non-sport mode. Any fix for this?

 

Unfortunately the only thing you can do is get rid of the car. I'd be willing to help you with this, I have extra space in my garage.

 

All jokes aside, I do have that issue though. My car is extremely stiff with the motons, sways, cage, springs, all the urathene, solid metal and aftermarket mounts...any little bump it is very hard to adjust the throttle and sometimes I feel like I don't know how to drive the car...probably look like a beginner, especially around town on bumpy roads and when starting on 1st gear.

Sport-mode is almost undriveable...

 

I tried this several times tonight but didn't hear anything from the engine. Once the final 15 seconds passes when the ignition is on, are you supposed to turn it off or continue leaving it in the on position? Or are you supposed to turn the engine on fully? Sorry I'm sure when you typed it, it made sense to you but some of us need a little extra help

Thx

 

Turn ignition to on (switch position 1) for 60 seconds then off (switch position 3) for 5 seconds then back to switch position 1 (ignition on) for 15 seconds - during process you do not turn the switch to position 2 (start engine). After the last 15 second step key is returned to position 3. Here are the starter switch position steps: 1-3-1-3.

 

Thank you! That's exactly what I did but didn't hear anything. Maybe my throttle is already perfect . Thanks for the reply.

 

any idea if a car w/ tune would benefit from this?

 

It may be the way it's tuned. Check with EVOMS. When I first put on the Proto flash I thought the throttle response was a little twitchy, especially in sport mode. However, the same flash was perfect for the upgraded vtgs, and I can even drive in town in sport mode without lurching.

 

sounds to me like that car should be on the track, trying to get from a to b as fast as you can, so throttle will always be either full on or full off, any feathering will be on pit lane...
