2014+ Engine & Transmission Tuning

[dbannerz71]

I assume that you must have increased the shift rpms because the normal tune for the transmission at least, does not have any shift going above 5600 rpm. The 4 to 5 shift and the 5 to 6 shift are both set at 5200 rpm. That's default for the firm and hard shift tune in the TCM.

The hyperteck tune lets you raise the RPMs and shift points by 500, turn off the AFM and turn off the TM if you wish. There are more adjustments as well, and that just a hand held tune. I just turned off the AFM, raised shift points, and top speed. Their engine tune only gave you 7 HP on 93 grade gas, I run E85 95 percent of the time anyway so left it at stock tune. My truck runs great.

Yep, can do the same in Diablo sport. I was really close to going with the same hypertech that you got. Went Diablo only due to the supposed ability to hid it from the dealer (tested by jaws52).

I got my diablo intune the other day and was frustrated when it couldn't read my PCM, but after emailing support they were able to fix that. However, I installed the tune and it doesn't give me any adjustable parameters at all. After it installs the ECM tune the Intune just reboots. I emailed Diablo and they said thats normal. I'm kind of pissed about that as the main reason I bought it was for the throttle booster and AFM disable.

 

Anyone else with a 6.2 able to adjust parameters other then just load a tune?

 

BTW drove the truck and it felt exactly the same after the tune..

When I installed the 93 tune and it rebooted I went into tuning and adjustable perameters and it gave me the options you are looking for. I raised the throttle response by 10% if I remember and turned off AFM. When I put it back to stock to bring it to the dealer I noticed a big difference, really realized how much just a canned tune helps these trucks. After I had the latest updates done at the dealer it doesn't recognize my truck anymore. I emailed them my pcm file copy and am now waiting for a response.

Wonder why that is? Seems if you set it back to stock, then dealer updates, when you go through the process again, I would have thought it would be as if you were installing for the first time. Apparently not.

That was my issue initially. My truck had the update done already. I've tried again and it still won't let me adjust any parameters, just install the "Diablo Tune." Not happy about it.

I bought mine before the claim was made by Diablo, I've used them before on my trailblazer ss and was pleased with them.

Mine does the same thing. Posted over on their forum but haven't gotten a response yet

Posted over on Diablosprt forums too. Mike just sent an update to try. I'm not sure if its vehicle specific or not but will post an update when i download it tonite.

I'm sure this has been covered before but I'm lazy to read through all 42 pages lol!!

 

Question for anyone that has put a wideband on their stock 5.3, what AFR are you getting stock?

 

I was looking on AFE's website at their provided dyno graph and it's showing a mid-high 14 AFR in stock form, I thought that seemed really lean for stock

I'm not exactly sure what you are taking about in regards to wideband lol but maybe this screenshot will help. I'm Diablo tuned so maybe a little different stock but AFR always seems to read 9.76:1 at idle or any other rpm/speed.

[nando87]

A wide band shows you the exact AFR, its a sensor that plugs into your exhaust.

 

Not sure how much I trust that reading of 9.76, seems crazy rich!

Any luck? Diablosport has left me just waiting..

Stoich is 14.7 and your target value, i.e. ideal fuel/air ratio. How do you get that it's really lean?

 

I can't imagine why anyone would put a wideband on a totally stock truck. Adding a wideband allows for precise custom tuning and there's little point in that without mods.

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.
