The throttle booster can't do anything about throttle-by-wire "lag". Any actual lag would be in the programming of the computer that decides how to translate physical pedal position/movement into changes in throttle plate position. The computer may be programmed to "soften" or "dampen" changes in throttle positions to make the vehicle more "driveable" to the average driver, or even to improve MPGs and emissions by reducing rapid changes in throttle.

The throttle boost simply exaggerates the position of the throttle pedal as seen by the computer. For example, with 20% boost, if you press the pedal to 10% of of it's physical travel, the computer will think that it's actually at 12% of its physical travel. At 83.333...% of physical travel, the computer will think you're actually at 100%, and everywhere from 83.333...% travel down to the floor will be "dead" travel which will all be interpreted by the computer as full throttle.

The throttle booster simply reduces the physical range of movement of the pedal needed to access the full range of throttle positions. It doesn't really affect throttle response itself, but just allows you to rapidly increase throttle more quickly with less physical movement of your foot. Psychologically, it "feels" more responsive and powerful, because it takes less physical action to get the jeep accelerating.

I'm used to sensitive throttle from powerful motorcycles, so +20% boost on the jeep just feels more "normal" to me. Especially with the manual transmission, the throttle boost makes getting started feel "right" to me. Without the boost, I always felt like I had to press the pedal excessively far to avoid stalling.

Conclusion: Just try different values and choose what feels good to you. You're not missing out on any hidden performance by using small amounts or zero throttle boost.

What kind of improvements have you seen on your 13? I need to get something to calibrate my new tires (285/70R17 Duratracs) and figure if this improves both power and MPG I am in.

What I can tell you is I have used programmers extensively on my previous sports cars, hemi trucks, and Duramax diesels. I believe in them, they have proven themselves to me and I am not afraid to use them.

Now the baseline...my Jeep is a 2012 Wrangler Sahara with the 3.6L (obviously) and the automatic tranny. It rides on a 3.5" lift with 35" KM2's and 4.88 gearing.

Note that I do not have a complete list of adjustable parameters in my hands. I was disappointed that I have not been able to get anything specific to the Jeep 3.6L to tell me what the programmer can/cannot do short of working my way thru the menus. One downside is the same programmer covers a gazillion vehicles so the documentation is very general. I have requested it from a Diablo Tech who committed to getting me something.

To start you can as suspected adjust for tire sizes, gearing,etc. as well as program the TPMS thresholds. You can also turn off traction control completely regardless of 2wd, 4hi, or 4lo. It also has throttle boost which adjusts the sensitivity of the throttle position sensors on the throttle by wire system to get rid of lag and make it more responsive.

First impression....WOW!

Given I was almost on empty I filled up with premium and loaded the performance tune (93 octane), and set the throttle boost to full (equates to 20% improvement). Note that I also have regularly used a simple bottle of quality octane booster with a fill up.

I can honestly say based on my "butt dyno" that it feels like a completely different Jeep. The throttle response is immensely different and very snappy and responsive. The trucks wants to get up and run now...From a dead stop on dry pavement this was the first time I was actually able to get my tires to slightly bark and the traction control light to come on. That I would not have thought doable. I drove it about 75 miles after setting it up and am VERY pleased and excited to get out and work with it some more, check the MPG, etc.

On the down side....really poor documentation comes with it...nothing specific to your vehicle and nothing at all unless you print the manual.

Secondly, unlike others I have used including the trinity for my Challenger, and other tuners for my late model trucks, this one does not YET (I assume it will with a future release) have different shift point options. It does I assume within the performance tunes adjust the shift points at some degree based on driving it however. Previously with the new gearing, etc. if I stomped on it from a slow roll it would actually bump into the rev limiter prior to shifting, and once power slightly dipped (made to do that to protect the engine), it would upshift and take off again. Not now, very smooth, crisp, and well timed.

Very impressed...more to come as I play with this further.

positrak No news, no updates. Bit bizarre. No further tests from me either, just in the process of trading in the '12 for a '13 10A. Remarkable how the end of the month spooks these dealers. So I'll be waiting on the '13 tune. Can't live without it.
05-23-2013 03:47 PM
Mopar2Ya Has there been any software updates?
04-13-2013 04:47 PM
positrak No updates so far. Seemed almost ripe a few weeks ago for picking but no luck. 2013 + all the other options that others have (lockers etc.).

Otherwise still plan a dyno and 0-60, so far for me all good moreso since its warmed up significantly massive difference in throttle response in sub zero vs above ordinarily, even worse when its super hot in summer. but so far warm weather the result is the same, same throttle response regardless, which is key.
04-11-2013 01:03 PM
GiantSchnauzer Ahh, slight correction, just saw the price, going for front lca first lol, a few HP can wait
04-11-2013 12:38 PM
GiantSchnauzer So if I get this I would have to reset my jeep to normal with my aev procal where I had the tips and tyre size changed for the automatic gear shift points, and this thing will do the same with shift points as well as "Tune " the performance?
04-11-2013 12:02 AM
Jkfletch7 Any updates?
03-30-2013 11:52 AM
Mopar2Ya I'm not sure if it's the tune, but my mpg is up from 14 to 15. However I've seen as high as 17.* last yr in warmer weather.

03-16-2013 06:36 PM
Mopar2Ya What few miles I've put on mine, I'd say the jk feels lighter. I found a local shop that is listed as a Diablo CMR tuner, I'm going to check on a custom tune & a regear. Elarson, has me thinking 5.13's. When new updates for the Trinity come out, let's list them here.
03-16-2013 05:01 PM
positrak phew..full and complete success took it down to near E, filled it to the top with 91, flashed the 91 tune and its full and complete awesomeness returned . Had me worried a bit. Without question, stick to the fuels the tune is designed for. Slightest deviation and its totally out of whack. Well not totally it works fine but once you experience the matching tune/fuel and deviate you know something is very off. Best way to describe it is, it's out of sync. gears don't know where they should be, bogs down on hard throttle, just simply out of sync. Matching tune/fuel, man it's like a race car. Same wow factor I got first time round. Not even sure why I wasted my time with the 93 tune in the first place, claimed output is the same. Thought the fuel itself might give it a boost but mine is 94 not matching the 93 tune. Definitely empty the tank and stick to matching fuel and tunes. Feels as good if not better with the 5% throttle boost now as when it was first done.
03-16-2013 09:56 AM
positrak I'm switching back to 91 tune and 91 octane, finally got through the 94 fuel. Have to say 94 never agreed with the vehicle eve from day 1 without any mods at all. Found it and still does burp on changing gears, not sure what the story is, but 91 is what I'm going to stick with as it matched and worked perfectly with the tune as well as with out it. I'm thinking that maybe the change over reset the transmission memory as that is what it feels like, like the transmission is still learning. I wonder if the switch over from 91 tune to 93 could have caused that or the throttle booster. I'll know once I switch back it gets corrected or feels the same. Still going to do a dyno once I get this settled down and back to how it felt best.
03-09-2013 06:37 PM
Mopar2Ya I know having a full tank of 93 would be better, but I just couldn't wait.
I hope it gets better w/miles & a tank full of 93, time will tell.
03-09-2013 05:32 PM
positrak also check on their forum there is a sticky about octane boosters, what is real and what is not or something. Only one brand/type considered correct. Something like that, details on the forum under one of the main forums.
03-09-2013 05:22 PM
positrak Interesting. I reduced the throttle boost from 10 to 5% much better for me, it seems to control the "spongey"ness of the accellerator pedal. Before at 10% it was like a plank either on or off, now back to 5% there is some play pressing the accelerator which makes it feel like I am using an accelerator. You can press it or release it before it gets to 2nd gear etc. As for changing fuels, I asked them and they suggested swapping fuel at 1/4 tank remaining or below. Tinker with all settings with what you have now, burn through the remaining fuel doing so, then do the 91 tune with 91 if you have it, that to me was a perfect match (now I got 94 fuel with the 93 tune -- not quite right yet). But do all testing with this batch of fuel, then when near empty fill properly and do corresponding tune in order to make your final determination.
03-09-2013 04:49 PM
Mopar2Ya I put a few miles on w/the 87 tune: it felt basically stock, w/maybe slightly better shift points.
I have sense switched to the 93 tune: (I had 2/3 tank of 89 + octane booster topped off w/93) it felt a little better, & a little better shifts than the 87 tune. I had the throttle boost set at 10, I'm going to try maxing it out at 20 next. I need to put some more miles on to really be able to give an opinion on the overall value of this mod, as it stands now I still feel that I need to regear to feel the changes.
03-08-2013 07:13 AM
positrak Think I figured this out. The throttle booster increases the throttle sensitivity, it is to get rid of throttle lag by telling the computer the accelerator has be depressed by "x". Problem is I never had any lag in the throttle to begin with, so as in the below pic, where regular stop and go driving I'm on the throttle in 1st as needed to move forward, back off brake, stop etc. Having increased the sensitivity, I'm now too close to 2nd and in the same scenario reach 2nd far too quickly and unnecessarily, so moving forward in stop and go goes into second, back off drops back to first, brake, stop etc. Quite annoying in traffic as the transmission is shifting back and forth like that.

I need to decrease it to 5% instead of 10 and see how that works out, otherwise remove it as I never had an issue in the first place.

Potency of it is pretty impressive if you need it not sure its needed on these jeeps or at least in my current setup.

Not quite sure yet. Before the tune the 91 felt just right, this plus throttle boost feels extreme

Going to see if it settles down by next week then make a plan for a dyno of it all.
Nice!

positrak From reading their forum they're right in the middle of the process of finalizing the 2013, like this week. From reading here and elsewhere, I'm guessing due to a programming change in the 2013 auto (apparently different to 2012's) is perhaps what the delay is e.g.

http://www.wranglerforum.com/f33/201...st-189926.html


keep an eye on their site I suspect the 2013 should soon appear.
03-06-2013 11:31 AM
Nesbittorange I loved the tuner on my SRT Challenger. I could have bought a 2012 Wrangler but opted for a 2013 only to learn the 2012 tuner won't work on a 2013. Anyone know what the difference/problem is?
Waiting for the 2013, throttle boost is worth the cost alone.
03-03-2013 10:56 AM
Mopar2Ya Elarson, how do you like the 4.88's? Too low, too high?

I just installed the Trinity in w/87 tune(need to go refuel w/93 before I switch to the 93 tune), but I may not drive the jk for a few days. I'll update once I put a few miles on. A few tips for those purchasing the tuner; the instructions maybe old/off a little, but it wasn't hard to figure out. I ignored the warning of draining the battery, do not do this, turn everything off & make sure you have a good charge. I got lucky, I got a "low voltage" & the tuner wouldn't continue, but it was before I got to the actual tuning. The jk gave no warning of low voltage, my guess is the Trinity is sensitive to actual voltage. I tried to update the unit before installing on the jk, don't bother the tuner won't tell you if you need an update until it's hooked up to the jk. My Trinity (date on package Feb 13) did need an update.

What I'll do is video it next time I'm in it if you want to see what's taking place. I'm not up on the technical gearing and shifting of these vehicles, so maybe you can determine from that.
That would be awesome!
