Your 2.8L Duramax MAP Sensor Needs An Upgrade
HTML-код
- Опубликовано: 8 сен 2020
- The MAP sensor that comes with the 2.8L baby Duramax is not capable of reading boost numbers needed when adding an aftermarket turbo. Well, Nick has the fix for you in this Diesel Insights!
Yes, our Stealth Turbo for the 2.8L is in R&D while we perfect it, keep an eye out!

This is why I like working with duramax tuner! They have solutions for problems that you may run into on performance building. Keep up the good work!
Stealth turbo in R&D now? I’m on the edge of my seat!
Oh, what a tease. :) Can't wait to see what these 2.8s can do. Next will be transmission upgrades.
Yeah!
I need one of those ladders with the body support.
I have a cax file and would like to do this with my LMM if it fits. I tried with a Honeywell 100psi but the result wasn’t great and resolution wasn’t either.
I cant find the part you showed in the video, on ebay or the internet, it shows me a different part for the L5P, can i please have an exact part number or link to the MAP upgrade?
Sweet! Now got to wait till they get cheap enough to afford one! LoL my 2006 cobalt L61 coupe F23(I'm first owner) is getting a little long in the tooth(need head gasket, chain guide and timing chain, rough times, rough times). Is anybody giving a crew cab regular bed(6') away? My daughter would love to have more rear seat room. LoL she's getting to big for my little coupe and 4wd would be great in the Alaskan winters!
Any updates? I’m currently looking for a runner from my 2018 2.8 zr2. Any help would be appreciated. Thank you!
So I can use the l5p sensor? Do I need a tune?
Interesting video. Speaking of MAP sensors, the sensor in a stock truck with no catch can and running EGR quickly gets "goo'd over". I can't imagine a MAP sensor covered in a thick layer of black tar is relaying good information to the ECM.
What are you using for turbo hoses with all that boost? The flimsy made in China OEM hoses worry me at stock boost levels. A kit to adapt the "clip" type mounts on the intercooler with better silicone hoses in pretty colors would sell like hotcakes! Gimme gimme...
if only there was a company that made high quality powder coated piping.....hmmmm
Nice video. Please correct me if I am misunderstanding your info. I down graded to the 2.8L Canyon. I do not pull any longer, but after driving the Canyon I noticed the stall when accelerating. I am not after more power/torque, but to eliminate the stall and improve engine performance. The GM part change and the Stealth, when available, can solve my issue? Thank you.
In your case a Pedal Commander would be a huge help.
How much boost can the heads hold?
The stock sensor has 5 wires and the L5p has 8 wires... what wires get connected?
05 LLY 72mm turbo from LDS. Pretty sure I need to upgrade the map, any suggestions as to which map I should get? Future plans are to go compound over stock. Stock fuel system but I only see 25lbs. Seems low to me for that turbo.

@Duramaxtuner can I also call you regarding my chevy express 2.8 duramax diesel upgrades? Thank you
I've been using hp tuners, and it seems the ecu has a hard limit of 300kpa. How do you get around that? Scaling? 400kpa in the manifold but the ecu thinks it's 300? How did you scale the other tables?
DOes HPT allow editing of the MAP linearization table? Have you rescaled it to the sensor?
@@Duramaxtuner HPT does allow you to modify the MAP Sensor linear and offset values. I have installed a Bosch 4 bar tmap sensor and scaled it accordingly, but the scanner still flat lines at anything above 300kpa. I understand there is much to be desired with HPT on this platform. I'm beginning to believe that the software is my issue.
I’m in Australia
And have a Colorado with a 2.8 duramax
What turbo upgrade do you do and do you supply map sensor and piggy tail
Hope you can help
@chrisdeegenaars1168 We manufacture the DT44 for the 2.8L Duramax. It can be purchased with the MAP sensor here on our website: duramaxtuner.com/turbo-chargers/lwn_stealth_2_8l_dt44_turbo.html
Do I need to upgrade from the stock turbo charger to see any benefit to the map sensor change?
Yes as the stock turbo only has a certain level of boost.
Does this apply to turbo diesel engines only or gas as well? By that I meam MAP sensor maxing out.
@Silent_Shadow your map sensor has the possibility to reach its limit when you start adding modifications to increase airflow. i.e. aftermarket turbochargers. However, simply upgrading the flow characteristic of your stock intake system will not typically be enough to overload a factory MAP sensor. If you are just adding an aftermarket intake system you should have no need to upgrade.
Are you guys still working on the turbo upgrade for the 2.8L
Yes, we’re only a few yards from the finish line.
How do you re-scale the MAP sensor?
there's a pressure value assigned to a particular voltage
Does the upgraded MAP sensor do anything to a stock build? Or is it only effective when other upgrades are present.
If you have an all-stock truck, start with tuning before you get into upgrading your MAP sensor.
@@Duramaxtuner Thanks for the info. I have been hesitant to upgrade my 2.8. i want a bit more but i dont want to do too much. I will look into a tuner

Anymore details on the stealth turbo you're working on?
Another round of testing is underway.
@@Duramaxtuner god speed!
@@HunterSkiff how’s yours working out now? Waiting for that video. I have my DT44 on the way along with this MaP sensor and Motorops working on tweaking my diet tune.
Any instructionals for this process?
hopefully they just sell it, or bundle it with the turbo, as a drop in ready to go unit
i have a 2.8L duramax diesel colorado..why my truck stall on 2nd gear when acceleration pedel is pressed but completely fine when you run it on just clutch pedal?
Hey duramax tuner is there recommended things to make a LLY 2005 duramax bulletproof I have a EFI live tuner on it at the moment. Any advice would be great.

@@Duramaxtuner ?
Does this do anything for a stock diesel, here in commiefornia they don’t allow a tune etc. trying to make improvements but it’s tough.
Our 2.8 tuning is CARB certified.
Will it work for the 2021 3.0 L
No support for those yet.
Who makes after market turbos or the 2.8L
Ask us in 2 months
@@Duramaxtuner can't wait
is there benefit for stock turbo?
No. You likely won't be making enough boost to need it.
MAP: Manifold absolute pressure, which measures from 28" vacuum to positive pressure
It pains me to see the use of butt connectors (and possibly the incorrect size ones; yellow is typically used on 10-12 gauge wire) on sensor wiring. In my many years at GM dealerships I am aware that GM approves of this use but my experience has proven butt connectors to have issues with long term reliability, especially on sensor wiring. The practice of soldering wire connections followed by 2 layers of shrink tubing (per GM exterior wiring repair standards) has shown to have more longevity and a cleaner look compared to 4 non staggered butt connectors.
If we, as professional automotive repair technicians, are going to ever get past the stereotype of "grease monkey" or "mechanic" we need to show our level of expertise to the general public every chance we get.
Soldered joints are more likely to break than a properly crimped joint with self-sealing heat-shrink. Any movement and a solder joint will split right at the edge of the solder. A crimped and sealed joint, on the other hand, will tolerate harness movement. There's a reason solder is not a common sight in motorsport or aviation.
ridiculous
Pro trick : watch series at Flixzone. Me and my gf have been using it for watching loads of movies recently.
@Ahmad Sebastian Yup, have been using Flixzone} for months myself =)
Booooost....
so not quite clear on this he makes it seem as if just the GMC trucks with the engine has this issue or is it every truck that his this issue.
This is specifically about the 2.8L LWN Duramax.
do you want to explain how the turbo can run away when the cal has vane angles and calculated turbo speeds limiters to prevent that EXACT situation?? Your vid comes over like the turb can run itself into a massive over speed in OEM form IF over the MAP sensor max is commanded. GM prevent that!! There are better upgrade MAPs available that don't require rewiring- straight drop in and play.
