Any luck? Diablosport has left me just waiting..

Did you email or post on their forum? I just posted on the General Intune forum with the copy of my PCM file and Mike sent me a new file to try within 24 hours. I loaded it in the Intune and just installed in my truck. Everything went smooth except for it won't let me adjust any parameters. I just posted my last tune written file and will see what Mike has to say.

I have always had no troubles when posting on their forum getting replies and help

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

Just been emailing support. All they said about the adjustable parameters is " we'll have an update soon." It wouldn't be a big deal if they didn't claim that their product could do all these things for my specific vehicle, then not follow through. I got an exhaust for my truck and the whole reason I really spent the money for the tuner was to turn AFM off. Just frustrating.

I'm not talking about stoich, I'm talking wot afr.. And anyone who is tuning I'm sure took a baseline afr reading, that's what I'm asking for. I know what the truck needs to run but curious to know what it's running stock.

 

If I remember correctly, Mine was running around 11.6-11.8 at shift point running 10% but they run lean as hell till 5k rpms due to factory WOT fuel table delay parameters. They also run pretty close to commanded AFRs so MAF seems to be dialed in pretty well from the factory.

 

I doubt I still have stock log from 2years ago but I can pull up a tune and tell you what the ECU is commanding if you like? I just don't hang onto all my scans after I complete a tune. I'll keep a few to record issues that I can reference back to if needed and a few completed tune scans to show customer what the vehicle is doing if he asks any questions.

Thanks for the offer, I won't need to know what the ECU is commanding I'll see that when we scan it.

 

I was really wondering how close does the truck run to the Commanded AFR, you answered my question. Just out of curiosity how much fuel did you add to eliminate the lean spot up to 5k?

 

I take it as these are not nearly as pig rich as the older trucks from factory.

Just goy my Diablew custom tune done. I got to say Lew is the man and turns these around quick and responds lightning fast. I only have 15 miles on it but will be towing a good 600 miles over the 4th so that will be a good shakedown. I can already tell the shift points are better and it holds gear far better then stock. Power is good as well.

They are not as rich, no.

I didn't add any fuel to overcome this, I simply adjusted values that lock out the WOT tables till the engine reaches 5k RPM and moved it down to down to 2K, then changed the multipliers in the WOT table to give me a 12.8-13.0 AFR when mashing the skinny pedal.

Awesome, thanks! Appreciate the info.

What are you using to make adjustments?

Using HPTuners.

 

Truck has AFE Momentum Intake, AFE TB Spacer, Magnaflow muffler swap.

Nice... if this is your first DI motor PM me your email and I'll send you a couple street tuned vehicle Calibrations to stick in your compare window so you can see what I did vs your stock calibration and if yours is E85 there are minor mods to those tables as well that made modest improvements to the power.

My apologies. Based on the follow up conversation, I misunderstood what you were asking.

Big is right about adding a wide band to a stock truck, definitely not popular but I'm one of those guys that likes to know how well the factory calibration dialed in. Needless to say, I was very impressed with these new DI motors, it's all the nannies that make me want to burn my face off.

Try to post on their forum, they seem to reply a little faster. I already got a reply on not having adjustable parameters and have sent them another file they asked for. I have worked with Mike Litsch (sp?) and he's been great.

      Tire psi

      By jgaudet99 · Posted

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page

      Some Assembly is Required

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.
