K2 Diablo Tune

I keep gettin a message saying "There's a problem with this drive. Scan the drive now and fix it" when I plug the tuner in to get any updates. Anyone else have this issue?

Never had that personally. I would definitely contact Diablo.

Please excuse my last post. Posting off a phone doesnt work sometimes. Ive noticed that people are deactivating the AFM. Any particular reason for doing this? Have you seen a drop in milage due to this? thanks.

I don't think AFM does much around town. I think on a long highway ride it would help mpg. I didn't notice a drop in mileage actually... I would imagine there would have to be but I didn't notice it. I can only speak for myself but the reason I shut it off initially was to see how it would respond and it really is smoother and more responsive with it off. I think the new AFM is too intrusive. My father has an 2011 and I feel like his only really comes in during coasting or really light pedal input. Maybe it doesn't do as much as ours but it's not as intrusive.

I can't recall exactly but when I updated my Trinity the last time I had to use an older Windows machine that hasn't been used in a while (I have two MacBooks but the trinity software isn't supported), I had an error message come up and I remember having to search around and make sure all the USB drivers for that computer were updated. Once I went through all that I had no issues. Might be worth a try.

Are you using a mac? If you are try windows. I tried my macbook first for my InTune and it wouldn't work at all... I had to use my laptop from work which is windows in order to get it to work.

Ha d a buddy of mine hook it up to his computer and was able to get it all updated. Hope to load it later this evening Thanks for all the help.

Does anyone know the nature of the update that came out on 12/4/2017?

I've updated my unit but haven't run it in the truck yet.

Haven't noticed a difference since the firmware update.

I've recently done the 93 Diablo tune on my 14 Sierra with AFM off, speed limiter off, firm shift. Haven't messed with the throttle values. I also could not update the unit on my Macbook, had to use a windows computer at work. Agree that the tune really livens up the truck significantly

math_10silverado · May 7, 2018

just tuned the truck today and only used the easy tune...

93 octane tune

hard shift (could shift harder i think im crazy)

speed limiter off...

ill try the advanced tune later im just wondering what advance tune to use if i run 93 octane gaz and what to change for shifting power... maybe higher rpm shift??

This is a great thread. I just leveled my truck and had bigger tires put on and I've been researching adjusting the speedometer. I've basically settled on the fact that I'm going to need a tuner. This Diablosport tuner seems to be getting the best reviews outside of BlackBear. I've also wanted to turn off AFM as well so this is an all in one solution. Now I just need to get the purchase past the Mrs. haha

After reading this thread though, I would caution everyone to be careful with the engine idle adjustment. If you recall, when these K2 trucks first came out, the very first recall for them was that the truck could catch fire while idling. The recall fix was a software update. Thinking logically about this, how does a software update prevent a fire? Likely, they adjusted the engine idle and possibly the cooling fan speed. Just be careful adjusting these settings and leaving your trucks to idle too long.

Just bought the Diablo i3 platinum, installed the the basic 87 octane with firm shift and changed tire size 285/60/20, made a huge difference with minimal settings, no more lag at take off no more trans trying to figure out what gear to be in, much better performance can definitely feel the extra horsepower. I have read that some people have installed their stock setting back then made their changes is this something you need to do or can you just update your current settings without reverting back to stock first.

Ordered it yesterday AM, delivered yesterday PM. Gotta love Amazon Prime.

No problem firing it up & updating. Installed the 93 tune with firm shifts. Easy peasy.

I think I'll try the hard shifts next.

I have never reverted back to stock to make updates. My understanding is the software on the Diablo goes through each setting regardless of what you changed so therefore I've never gone back to stock to make updates. I don't remember seeing that in the manual either.

I was worried about this when I tuned my Colorado. Originally went for the 89 then went and changed it to 93. I was sweating for a couple months that I deleted my factory tune by not restoring before going to the 93. Especially when the tuner says something along the lines of copying previous tune. Long story short tho, when it came time to get rid of the truck I restored it to factory with no issues.
