It seems many of us have trouble with the throttle being very touchy after tuning with the superchips flashpaq

I have a theory about whats wrong but who knows if I'm correct. I would like to get some info from other people on here who have a superchip flash paq.

I am curious if it is mainly people with a manual JK who notice the issue, or if auto's are having the same problem. Here are my thoughts about whats going on, copied from my post on the superchips board.


Quoted from my Superchip post

I spent a lot of time tuning my Subaru I had before this, now granted I'm not an expert but here is where I think the problem might be.

A lot of people are driving automatic Jeeps now. The pre-loaded tune I don't think destinguishes between Auto and Manual jeeps. It would make sense to me when the tune was created it had a heavy influence of correcting the dumb things automatic transmissions do. This being said a lot of people's issues I would assume would be getting going in an auto. So if you give it more power with a slight touch of the throttle in an auto that'd work great to over come the torque converter and get everything moving. Conversely this would not work as well on a manual. So if the tune is setup to give a good quick powerful burst with minimal throttle input for an automatic which would work great for an auto, would make a manual surge and lurch with minimal throttle input, because there is no torque converter or anything it has to over come.

It seems as if the throttle either opens to wide or is throwing to much fuel all at once with a manual. Also when you let off the throttle it completely closes. The stock map doesn't seem to do this. It seems to progressively close so you can let off when desending a hill and use the transmission to hold you back. The new tune does not do this.

Is there a way to get a tune that uses the new timing and such you guys have used to create more power but leave the throttle response the same as the stock tune for us manual JK's?



I am just hoping to gather this info so we can hopefully get superchips to help make the tune even better for all of us!!

I am in no way assosciated with superchips. I'm just curious and want answers and solutions haha


Please post whether or not you've noticed your throttle repsonse being very touchy after updating with superchips, whether you are auto or manual, and what gears you're running.

Also if you have any ideas or input I'd like to hear them, hopefully superchips will too

Thanks!!

 

I would almost like mine to be a bit more touchy. I drive a manual and have the superchips and still have the throttle lag that everyone complains about.

 

I beleive the lag has todo because everything is electronic. This is unfortunately a characteristic of drive by wire.

I think the lag is pretty much gone in mine, more of the issue is when you step on the throttle just a little to crawl or when going slow in a parking lot you can't ease into it.

There is no fine adjustment, fine control.

 

I'm confused, couldn't the "lurching" be modulated with a bit more finess with the clutch or am I missing some thing?

 

It could and does. By why eat up the clutch? I didn't need to ride the clutch in a parking lot before the tune.

Mostly I would like this fixed for off-roading or driving in snow and ice, which my road/house is still frozen, hasn't been above 30 degrees in over a week.

The reason, is now when you let off the gas or just slightly touch it, it jumps. This doesn't allow for much control when desending a large slick muddy hill, or icy roads.

 

One of the great benefits of the Flashpaq is that it *eliminates* or at least greatly reduces the throttle lag programmed into the stock PCM profile.

The only time I would ever want less throttle sensitivity is if I was inching along like in rock crawling.

If you think your throttle is too sensitive then just scrub your foot along the edge of the firewall for more resistance or maybe you just need to drive it that way for a while to get used to it.

 

I completely understand your point.

It is way way way to touchy. It takes pressure to get it to even give it gas. There is a dead area in the pedle. once you over come that area it is a quick lurch/surging movement. I haven't spent the last several days trying to get used to it.

It was almost impossible to creep in 4lo when I was out on some icy trails yesterday.

The problem is mostly in first and second gear below 2200 or so RPM

 

I can completely second this problem. Just flashed to the 91 octane tune yesterday from stock and first time in a parking lot noticed this issue, came home to search and found this thread.

I can understand people having a hard time relating unless they experience it. It's honestly probably even too subtle to take video of but it IS there, IS annoying and was NOT there before the tune.

I don't feel like the problem HAS to be there to fix the throttle lag issue either, in a way it feel like an exaggerated lag. No matter how slowly you press the throttle it feels like it goes from 0% throttle to about 10-15% throttle at the snap of your fingers. The best description is like JonP said, there is a 1/2 inch of "dead zone" at the top of the pedal where nothing happens then BOOM power on and jump forward, then when you let off the throttle a bit, not completely, it's as if you took the pedal from 10-15% to lifting completely, power dies and you lunge forward. Rinse and repeat the whole time through the parking lot, crawling or any other slow speed finesse situation.

Something I haven't tried yet is the "crawl" tune. It states better low speed throttle response. I just don't want to loose the power that the 91 tune gave. It really is a big difference over stock. I love everything else about the tuner, except this glaring bug... I'll post back after I try the crawl tune.

I'd like to hear from anyone else that has the superchips that either has or has not experienced this issue after tuning.

 

I have the same issue on my 6speed. i do alot of driving in downtown pdx and that is where it shines. inching along at 10mph or so it lurches alot, kind of annoying.

 

I have had the same problem using the fuel saver mode and the 87 tune. It is way more pronounced on the fuel saver tune than the 87. The low thottle surging has been an issue in parking lots, gas stations, and off-road. On-road it's not an issue as I just throttle though the surging.
