Intune DCX and Hemifever Tunin'
Thread for my review and progress using the Intune DCX and Hemifever tunes.
First, a review of the equipment:
When looking at the pictures and imagining what this device would feel like I expected a much more substantial device. Something a bit more solid feeling like a smartphone. For close to $500, why shouldn't it feel solid? Well, it doesn't and it feels like a toy. I am worried it will explode if I look at it the wrong way.
Pretty simple device, a simple touchscreen interface, plug at the bottom for the OBDII cord, plug at the top for the USB cable. Easy to use as long as you take a minute or two to look at the quick start guide and user manual that shows up in your disc drive when you plug it in to your computer. What it does lack is information advising you'll need to do multiple off/on cycles which is difficult to do with the button start in. After my first attempt, I had to pop the button out to make the process easier.
The Diablo tunes:
87 Octane is all i've used so far. It's advertised to improve driveability, HP and Tq without the need for premium fuel. It claims 18hp and 20tq. I don't think I feel any of that HP and Tq improvement but driveability is much improved. Auto now feels much more like Sport and I haven't particularly felt the urge to spin it in to sport like I normally do every time I start the car. I've yet to determine if this improvement in driveability has any impact on the other selec-terrain modes and haven't found any conclusive evidence either way. The transmission definitely holds gears a bit longer and is far less excited to move up to the next gear prematurely. It doesn't however really solve for the obnoxious lag in down shifts if you need to pass someone.
I haven't run any of the other tunes yet but do plan to run the 91 tune at some point. There isn't 93 octane readily available here so I doubt i'll every load the "Diablo Tune".
I haven't had the chance to load these yet as I have a full tank of 87 but plan to fill up with 91 once I get to half a tank, then load the Hemifever 89 tune. I do have to say that the customer service from Sean at Hemifever has been excellent. I placed my order late Friday night, he shipped it early Saturday and I had it on Monday! After loading the 87 tune I sent him my "last tune written" and had the the 89 and 91 tunes in my inbox the very next morning (sent it to him late in the evening the night before). More reviews of Hemifever to come as I get a chance to play with the tunes...
My background with cars and tuning:
I've owned two BMWs prior to the jeep, a 1997 BMW 328i then a 2003 M3. Just basic bolt ons for both...intake, exhaust, rear diff in the 328i. I never ventured in to any software tuning with these as they generally would do absolutely nothing for performance besides improve throttle response and maybe get you a horsepower here or there. FI was really the only way to get any extra power out of those inline 6s, so I didn't bother. So this is new ground for me and i'm pretty excited that tuning can actually net some gains with the Hemi. Currently I just have a Volant intake on the Jeep.
