HP Tuners for 2005-2015

Here's my N/A 2015 6spd truck with a Volant intake scoop plumped to the stock airbox, and a URD Spec-U exhaust.

Not maxing out the MAF, but thought you folks might like to see.

 

This is my buddies trailblazer ss

 

I like how the table tip at the bottom says if you screw it up you can brick your ECU.

 

Wow. That's quite similar to the SAAB.....

 

Because, same chit? I call them Saablazers.

 

Yep, my brother was hoping to grab an Aero so he’d have the 6.0 but he couldn’t find one locally.

 

GM owned Saab at the time so makes sense. However the weird Saab during that period was one based off Subarus.

 

@Roostfactor or @loginfailed , what is the MAF multiplier, for engine HP?

 

Here is the simple and beautifully executed line graph for modifying the APP to TB, on the Haltech Elite. This was taken before adjustment.

 

I was *only* in 3rd gear at 5000, Let me see what it'll pull at full song.

 

Supposed to be MAF x 1.18 = Flywheel

 

Inquiring minds want to know.

 

anybody know if you can adjust the shift time and shift pressure on the HP tuner, similarly to what can be done with the 4L60 GM transmissions?

191g/s x 1.18 = 225.38 considering there may be a little left on the table the formula seems pretty accurate.

 

So I got my MPVI2 yesterday and tried to hook it up today. Got it registered, added to my account on HPT, updated drivers, and headed to the truck to get some freaking data!!!
Well I quickly found out what I thought I remembered when I first installed the UCON. The connections that go from the UCON to the ecu are via a type of ribbon cable and are not long enough to remove unless the UCON/ECU combo is removed from the vehicle and separated.
So I tried using some Top Secret instructions to disable the UCON's CAN1 communication and don't know how to input what I need to in the UCON to turn it off. I have sent an email to Scott to see if he will provide me the instructions. I know he wants to keep them secret so I will not post publicly the procedure if he gives it to me.

When I have more time I will go the UCON removal route but it will get old real fast having to remove everything just to make a quick change.

 

Any way you could PM me if he gives you instructions? I wont post anywhere and i likely wont even use it, but its got me curious.. the more you know right

Doesnt seem like theres a whole lot of folks on here running the UCon

 

Just put your spare ECU in and read that one.

 

KISS

 

I uploaded a rather aggressive throttle map (nearly 1:1) with some lag on the lower end of the spectrum for drivability at low speed/throttle input.

It certainly wakes the truck up and it's EAGER to get going. It's amazing.. I'd wager a $1.00 that adjusting the throttle mapping alone and leaving the rest of the tune stock would make more difference in seat of the pants feel than $2,000 worth of bolt-ons.

I'm going to return my throttle mapping back to a less aggressive version as this would be WAY too much for off-road use, and my truck does get used in that capacity so it's not all "race truck" for me.. (boo, I know..) But I do have a very workable aggressive throttle mapping strategy.

Today I'm working on dealing with some open loop fueling issues. I've got things pretty well figured out, but I'm dealing with some of the "nanny-features" ruining the fun.
