Hi People !

I installed a Steeda CAI along with a Steeda tune for their CAI a while back and I'm extremely pleased with the results. The car performs so much better with it, not only power-wise but it also revs quicker and is easier to drive in stop 'n go trafic, etc... (me drooling... love that stang)

However, the car seems to lose a little bit of these characteristics in about 5 to 7 days. When this happens, I only reflash with the same tune and the car feels vitalized again. It happens to me both with the premium & regular fuel CAI tunes.

I know that the ECU will adapt after a while, but I always thought it was the other way around, i.e. the car would start weak, then become -and stay- strong.

Steeda told me that they are starting to see the effect of cold on some tunes as most owners started modding their cars only this spring / summer. ( I live in Canada and drive my car in the snow too).

I don't mind flasing the car this often, it is a piece of cake and requires only 2 minutes.., it's just that it seems strange and would like to know your thoughts on that, and find out if someone has seen this already.

Thanks all !

 

With a Flasher, "losing a tune" does not exist....I think you may have a case of the mod bug...time for another go fast addition :-). You might be getting used to the power. No joke, I tune/mail order about 15 of these a week and have never had an issue like this.

The adaptive fuel functions will not change anything enough that you will notice a deat of the pants change and these "corrections" happen faster than you would think.

If you have purchased the X2 from us, please swing by the shop and I am more than happy to take a look at the X2 and vehicle for you as well as go over the procedure to flashing the PCM.

If you have not and would like us to take a look at it, again, please swing by and I am more than happy to help.

I have the Steeda CAI with the 93 Octane tune but with the Predator tuner. My car seems the same since the day I installed it. (Power!!!) It's gotta be all in your head.

 

I also have the Steeda CAI and SCTII with a custom tune from Steeda....was running the 91 octane and just switched to the 94 tune. feels amazing with no loss of power whatsoever...i think you just need to keep adding power mods now to make you happy.

 

Hi Paul, yes I did buy it from you, and using tunes you personally worked on . I exchanged emails with Pat who said the same things. Like I said earlier this is not that bothersome since a flash is only 2 minutes away.

When this happens I make sure I flash the car and take it for a ride right after so that external conditions are the same, aka I come home, flash the car and go test it within 5 minutes.

I do feel a big difference in part-throttle behavior before and after a flash, not necessarily in the amount of power produced but the way the engine revs. Before the flash, the car acts exactly like the stock engine and does not rev as freely as with the tune. It also helps in shifting the car especially from 1st to 2nd.

It is a little weird and I'm not implying there is something wrong with the tune or the flash... I would like to drop by but it doesn't bother me that much (and since you're in Toronto... )

Since nobody seems to believe me is there something I can measure with data logging to find out if there is something wrong ?

Paul, you and Pat are the best, take care !

 

just bring the car by and I will take a look at it. Always here to help!!

I do all of the tuning, so feel free to ask me anything.

 

Took a while to find this old post but the fix seems to be the throttle-by-wire calibration. The car doesn't lose power or anything but throttle lag was becoming more and more noticeable until I reflashed the car again. ALl I need to do now is recalibrate the throttle by wire (ignition on, let the dash ligths go off, then slowly depress the gas pedal all the way and back on again). On my car I can hear a high-pitched electronic noise. VoilÃ*, instant throttle response restored ! Hope this helps someone !

 

It's seems like mine was reacting in the same way.. Anyway, how do you recalibrate for just the drive by wire ?? My X-cal II doesn't have any settings for the drive by wire, that I'm aware of..However, if any of you aren't aware of this yet..Steeda now has a high flow inlet elbow, as an upgrade for the CAI..if you get a chance to check out the website, it's located on the home page, right below their supercharger..

 

As I was explaining, just turn ignition on, let the lights go off, then slowly depress the gas pedal all the way and back. You should hear a high-pitch whine. Turn the ignition off, then start your car normally.

Thanks for the heads-up on the elbow !

 

I thought there was a setting with most tuners that let you manipulate the throttle sensitivity?

 

I hope this doesn't sound like a dumb question, but when you say turn the ignition on..Do you mean start the vehicle ? or just turn the ignition, to the on position ?? there are those who may interpret this, as either way..Also, after depressing and releasing the gas pedal, how often is it required to reflash ???

 

Just to on, not start.

 

Thanks Rondosa, I just wanted to be sure that I understood correctly..Guess it's always better to be safe, than sorry..

 

I forgot to ask, do you slowly depress the gas pedal and release it, every time before starting your vehicle ?? or is this only required, just once in resolving the drive by wire throttle lag issue ?? anyway, thanks once again..

 

i've only ever done it once. not sure about other people.

If all it takes, is just once ?? and you haven't noticed any throttle lag since..Then it must be working, which is more than good enough for me..Thanks, for coming through once again, Kristina
