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 )

      Enjoy the new truck, it’s a beauty. I’m glad you’re keeping the OBS, I love those old trucks.

      With large equipment or deep mud it is more of a use the higher gear to avoid spinning tires, getting stuck because of spinning tires and doing damage to your machine. The idea is if you run out of torque before you spin tires you can still downshift for more torque. If you are just spinning your tires in the lowest available gear you are stuck and things break.   Automatic transmissions, traction control and electronic transfer cases change the calculation a little as you the driver have less control over each piece.

      My First Project and GMC has me stumped

      By davester · Posted

      are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.
