a whole other motor..

I was excited over the new '16 motor getting a boost...but oh well.

It is the stock motor now and some act of god it is holding. Even at 10psi. Fuel is holding out also still haven't raised the base line fuel or even tps at wot is still at 83%. There is a fuel cut off just before shift that is causing the fail safe in the boost controller to cut boost. So it falls on its face with cutting 100% boost at shift and starting back again building in every gear. I can change any boost setting in LM programming but the concern is going lean at 5800rpm. 

And that is why I am working on getting the replacement engine going. That and even with more fuel the rods will never stay around over 600rwhp. I'm starting my drag car build in 60 days so need the truck done. That is a LSX single turbo 1500hp. It will be class car but thinking we may just grudge it.

Gonna be awesome one way or another.

 

I was quickly reading data values in my dads 2016.. found a 650 psi bouncing around.

I am guessing that is direct injection.

 

I have no clue, hardly learned anything yet.

I found divorced water pump, and a measure for humidity, that can alter AF and timing.

 

lots of variables.. I bet the 16+ gets an aftermarket guru in the future.

Yes like anything new it is more difficult and costly. I have called 6 performance shops in my area and all said hell no. they will not tune or dyno truck. I'm great at the old LS tuning but this new stuff is a curve. I real good and old friend has offered to teach me everything. So I will bit the bullet and learn for myself. Need it for the race car anyways. And he is the best there is so worth it anyways. 

UPDATE*** Learned how to data log boost so I need to log that and adjust the SCG-1. Nice boost controller but hell to program. 

Ordered (again) rear bumper with NO STEPS and new sensors. Body shop will repaint it soon.

Ordered a Vortech 3.5" cone insert. Will install it at the down tube at the fire wall. 

Recall on the SES system but dealer whats my truck to check it over and then order the part. Such BS. So I will just have the part mailed to me and F*ck the dealer. I can plug in the module myself. 

Side note tuning at 12.4psi  and holding......

As far as those values it is about right but I was speaking of the base line inlet pressure it is under 90 and I see people maxing it out at 118.4. Once I can afford (have new engine ready to go ) to MAX up this setup I will push it but for now I have to live at under 600rwhp.

****NO CORNER STEPS****New bumper is here. For the price I also ordered new sensors. The paint cost on the. Crimson tintcoat is so high I want all done now. Bill was around $2700.
Thinking about getting my extra tail gate handle painted...
Snowing here so exhaust mod needs to wait. c42f425ef20c1b780743dc94ecfe80c2.jpgfce3aea4e7609caffb44d7623fb75c79.jpge55a0f6ac062553d565c4ae1b62500b2.jpg

This step-less bumper is from what year/model/supplier?

Well the body shop had a listing through Rockwell. But I don't believe GM ever made one.

It is for 2014+ 

all in all it was $400 shipped. 

Body shop said like $1100-$1300 bumper, $220 plastic upper, + side steps, +sensor mounts,+$470 for paint, and the computer said install requires the bed to be lifted up to get to bolts.  

Believe it or not the company offers it for $414 shipped and free pro paint matched to you code color. Insane.

I read every post to only be disappointed with your truck not being done. Finish that thing up and post a good long video! Looks great

I believe it was some of the 14 sierras that has the stepless bumpers. Maybe the allterrain ones? I remember hearing it somewhere a while ago.

Yeah the issue is "done" it is tuned very well and even pulled a few 12.4psi days. However this new platform is insane. The newer truck allow for so many extra tuning options. And it is had to say it we are getting everything out of it. I believe I am NOT getting its all. I have some close friends and family that own the largest OEM company's and work on the board at GM . So last week I emailed them. And have a appointment to get it looked at. I'm told 600rwhp is fine. On stock block. So we will see.
Stainless vortex cone came in and I hammered it up the tip. Don't notice a sound difference but need to get it up to temp and see how it is. 282b714cf552e5fb3b7d0b1fee952126.jpg36479411643eef2eac13a0c9c438818f.jpgf931c524f9c9c4f037ef235bbd6ec6df.jpg

A bit late but yeah early 14 Allterrain had no step bumper. I like it better than the step ones. Hopefully I'll come across a no step bumper.

Didn't know that. But again at 414.00 painted your factory color band new shipped. Super cheap upgrade. More so that my insurance paid $2700. HA

You have a website or something for the company you got it from. For $414 I might buy one myself.

Not sure where he got it from, but I know you can get them on eBay, either primed or painted.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      By jake111 · Posted

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?

      Tire pressure for 37s

      By PBNB · Posted

      Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter
