Has anyone who has been running a diablew tune for a while now experienced that it loses some of the responsiveness after the truck relearns? It's still better than stock, but not as responsive and fun as it used to be.

I wondered that as well if the TCM would relearn and if it would change over time from the initial Diablo setup. A few days ago I just restored mine to stock then reinstalled it and only modified AFM from off to back on and throttle from 0 to +2, then same firm shift with no changes. I swear shifts seems better. These model trucks are just an oddball of well odd happenings lol.

 

I was just reading the thread on turning off grade braking that apparently helps shifting. Odd, just odd.

I have received numerous PMs asking about my tune, so many in different threads, I don't believe I could find them all, so I thought I would just initiate a seperate thread to address it. This may be

I just had Black Bear tune done and wow my truck at full throttle shifts into 4th at 100 mph. Transmission shifts so much better. Throttle response is fantastic. Best tune I have ever had done.

Ok, there seems to be a little confusion and a lot of misinformation passed around the internet that WILL eventually bite one of us in the butt when they go in for a warranty after they get their truc

Are you running just the regular diablo tune or diablew? I wonder if the grade braking would help lol

Just the canned Diablo 91/flex tune. Which I've been pretty happy with. I have not experience much odd shifting with it. Only a rare clunk during WOT shifts. Are you using a Lew tune? How is it over the canned one?

I liked it a lot better than the 87 canned tune! It still is probably, just doesn't seem as responsive as when I first installed the tune. I'm going to try reinstalling it tonight.

i think ive narrowed it down to black bear. I wish they would come to tampa for in person.

 

What made you decide on black bear? Just curious.

Future updates no charge really. Everyone seems to love blackbear and they can get future updates on the fly.

Yep this. I am leaving for an 1800 mile road trip tomorrow so I emailed them a few weeks back for an efficiency tune. I now have a tune for road trips and one for performance daily driving. Since my truck was tuned by Blackbear, I've been loving my truck more than ever.

How long have you been running the Lew tune?

Probably about a couple months now. I just installed a CAI and I'm gonna do my exhaust this week so I'm going to log data and send it to him again.

No problem, it is definitely a lot better than stock. Kinda wish I would have went to a local shop and actually had them do it in person, but I was really busy at the time. I've heard good things about Black Bear too.

The guys were just in Orlando. But if there is enough interest, they will go anywhere.

 

Hi Jenna. Question for ya. Are these new trucks capable of "relearning" after a tune is done so as to modify some of the performance enhancements that the tune was initially intended to change? (Am I making any sense lol )

There is some relearning.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?

      The use of absolutes like "always" to describe gear selection, and giving free advice at a boat ramp sounds like a recipe for disaster. It's a boat ramp, not a farm, for starters.   IMO gear selection should depend on the obstacle. If low range is working and this is a slower speed, controlled ordeal, I'd keep using that.

      I had a boat for many years, never had a problem even with a 2 wheel drive 93 Silvy for 20 years. Good tires, proper use of the gas pedal worked.
