    Windbooster review

    Hiyall! This is my review of the EVC iDrive Windbooster in my 2015 JKU 3.6 Auto. I chose it because at $299, it looked to be more adjustable than the similarly priced Cammus Wind Booster and the more expensive Sprint Booster (which does have a good reputation).

    For those who are wondering what it does, it modifies the signal from throttle pedal to make it seem like you are pressing the accelerator more or less than you actually are. It can't make the engine or gearbox faster or react quicker but it can make a car feel faster and feel more responsive. You can achieve the same by changing your driving style but if you can have electronic assistance to make it easier, why not?

    Firstly, I reckon the name is stupid because it makes me think of a can of beans.

    It was easy to install (plug and play) with decently lengthy wiring but mine is hidden next to the steering wheel - its white background and blue LED display irritates me because it doesn't fit in with the rest of the interior and back-lighting.

    The controller is easy to use with a button to select program and another to select the level. There are 4 programs: Normal (stock), Economy 0 to 9, Ultimate 0 to 9 and Automatic.

    Economy 3 is really nice for beach driving and Economy 0 makes low-range off-road crawling easier. While it doesn't replace crawling by loading up the throttle using the brake, it makes that easier too. On-road, Economy feels the same as towing something and can be frustrating because you have to really mash the pedal to get big throttle changes (i.e. for overtaking).

    Ultimate 2 is my normal driving program. Ultimate 0 and 1 are OK too but 3+ makes the car feel too jumpy and the auto gearbox constantly shift gears at the lightest touch or release of the throttle, even when cruising at highway speeds. Ultimate 9 is a blast though and really highlights how nice the Pentastar's power delivery is.

    Automatic is OK and actually feels progressive but it is way too aggressive for my liking. I am not scared of full throttle but I got tired of the looks I got when the rear tyres chirped at take-off and very tired of cat-footing around turns, especially in the wet. It makes it difficult to predict how the gearbox will react to throttle changes, which doesn't fit in with my driving style.

    Overall I would give it a 6 out 10, with one point lost for aesthetics (it's important to me).

      That was one of the most acurate and seemingly non biased reviews I have ever read on a product like this. Normally there is some garb about 15%+ increase in economy and power which always gets my goat up.

      That was honest and straightforward with factual recounts of exactly what it was designed to do and how it does it (and you are a local Sunny Coaster too!)

      Nice work.

        It is my understanding that the gearbox "learns" driver behaviour. How does such a device interfere with this?

        Yeah I agree this is probably the first review of these types of products that doesn't promote a power increase.

          I have mine on U7 for onroad (U9 kept making my muddies screech at the lights lol) and drop it down to U2-3 for offroad

          Bloody awesome bit of kit, makes the accelerator much more responsive - I'm not after more power, etc - just wanted faster response from the inbuilt electronics in the Jeep

            I have a similar module called a 'Torque Tuner', which transformed my 3.8 manual with 3.21's to 'drivable'.
            Pickup is more linear, and smoothes out throttle. Even in mud.

              alot of the response issues seem to be with the pedal angle. does this and an adjusted pedal angle make too much difference??

                I've gotta say that if the reviewer likes the result with Windbooster, he'd be ecstatic with a Sprint Booster.

                I've used Sprint Booster in both 2014 KL Trailhawk and now more recently 2015 WK2 Limited - and it's been fantastic in both - tho much more so in the KL than the WK2 because the KL's throttle / trans behaviour was much more flawed than the WK2 to begin with.

                In the KL IMO the Sprint Booster became essential to the car being driveable by any reasonable standard and anywhere near decently safe - but in the WK2 it's just a nice bit of enhancement to already very nice driveability.

                The Sprint Booster has never made me feel like this reviewer describes in terms of needing to be careful with it tho!! - maybe it's because SprintBooster has basically 20 steps of "sensitivity" or the description that Windbooster makes the throttle move more than the accelerator pedal input is NOT the way Sprint Booster works - which is always a direct proportional equivalency between pedal and throttle - ie. zero pedal is zero throttle, 50% pedal is 50% throttle and 100% pedal is 100% throttle - the different settings relate to how quickly the throttle responds to the pedal.

                Something the KL used to do that I'm not sure whether the WK2 does is that in factory form there was a RATE response as well as just reaction to pedal position - ie. not only was it horribly laggy, but if you shoved it a bit to quickly it would then suddenly respond way TOO quickly which could be pretty terrifying and bloody dangerous (I had a Subaru Forrester do same thing to me as well tho, so some form of rate response is probably a std part of fly by wire). Once I put the Sprint Booster into the KL tho, all that was gone and it behaved like any normal car - very good and direct response with no sogginess OR sudden unintentional viciousness.

                The WK2 is nothing like the KL for those nasty behaviours in original factory form- but it has a kind of gentle initial input - tho if you want it to go then yeah just keep pushing the pedal down and she'll go - but with the Sprint Booster it feels much more direct and responsive straight up from zero pedal onward - BUT without being scary in any way like the reviewer of WindBooster mentions. In both the KL and now in the WK2 we run the SprintBooster on Green 7 (there's "normal" green 1-10 and "sport" red 1-10).

                And I'll say again that Sprint Booster does NOT make more input of throttle than the pedal is set to. It really shits me when people WHO HAVEN'T USED IT claim that's all it does...
