The new C8 Corvette uses the same ECM and the aftermarket will have it unlocked within weeks of launch. It was only on the ZR1 for the C7 generation, so there was little incentive to crack it for the dozen guys who would want a custom tune.  Now that it is on the Corvette, trucks, and Blazer, it will get a lot more eyes and keyboards on it.  

 

I'm not too worried. Just a waiting game. This guy wants a big cam and eventually a blower.

It will not be as expensive as the ZR1 but likely similar to the L5P trucks. If you want to add boost it will be worth it but more expensive then the 14-18 trucks. For the casual bolt on guy it will b

I’ll wait it out. I got all the street racing out of my system with my duramax. I’m just enjoying the smooth ride of a half ton for now.

Actually I’m well aware of how the process works. I just got rid of my duramax. Aside from the ECM it’s a 10 credit unlock. I don’t think I had any false information in my post. You can send yours t

That is an interesting thought. I would have to disagree since the 19 ZR1 and 19 DFM trucks do not use Global B architecture and the 20 C8 and some new Cadillacs are debuting that which is a major change in hardware and electrical systems.

They will eventually get there but it will take time and be expensive. The C8 will not be “unlocked” within weeks of launch but I do like your optimism.

HP Tuners now has a modified ECU to purchase that will allow for tuning, but at $1,400 I’m not sure how many takers they will have. Unless you are going forced induction or cams, I don’t see how you could justify that price to pick up 10-15 hp. https://www.hptuners.com/product/e90-modified-ecm-purchase-ecm-exchange-service/


$1400 to unlock the ECM you send in from your truck.

Then $500 in credits to license it.

So $1900 if you know how to tune it yourself and have an mpvi2. If you don’t then expect to spend closer to $3000.

Jet Performance 21410 Jet Power Control Module Stage. Amazon says it will work, I even contacted JET and they said it will work, I even made sure to distinguish between 8sp and 6sp trans. Said works with 8sp trans vehicles with 5.3L ecotec3, bit dosent change tranny info. Summit racing says it will work with the 2019 Silverado LT Trail Boss. I don't know tho. Kinda hard to believe this will be plug and play and noone else can't brake GM's code.

I find that very hard to believe, plus you couldn't pay me to run their stuff.

so still no tunes available? ugh


Diablew has something in the works. No telling what the final cost will be though.

What about inline tuners?  Like a Power Commander that bikes use, but for trucks?  Box that intercepts the signal from the ECM to the injectors, same with the coils...  Takes whatever the stock signal is, and changes the pulse to the injectors to add or remove fuel...  It is transparent to the ECU so long as it also interrupts the lambda sensor...

ECU tuning us usually preferable, but when ECM's can't be tampered with, having an inline tuner and tossing the vehicle on the dyno and just mapping the entire rev range at each throttle input...

Is there such an option?

I think this a definite possibility. Because in the past the ecu could be cracked fairly easy the need was not there for gm gas vehicles. But now because it is much more complex I think we will see piggy back types of tuning devices.

In some ways, piggy back systems are better in that they don't touch the ECU and so diagnostically there isn't anything written that would show up as "tampered with" on a dealer scan...

now, you might want to remove it prior to a trip to the dealer, but I have never had a motorcycle dealer give me a hard time with having one installed.  Now, if my tune did something, like I ran it so lean or I stupidly gave it 40 degrees of ignition advance and blew up the motor, yeah, I would see that claim denied...

Dodge went over a decade with no one able to break their programming coding on their ECM's. I dont know why people think GM or any other manufacture cant keep people out. If they really wanted to make it unbreakable GM would do it. The only reason GM allows people into their ECM/TCM is because of the racing teams who need access to the systems. I am sure people will get into the systems, but it might be with the help of GM and or some sort of license fee that GM will charge those tuners for the info they need to be able to get passed the encryption protocol.

You can thank the EPA and the outcome from the Bullydog diesel tuning that was resolved last year. The EPA forced some of this issue along with the Corp Atty types who are worried someone will hack into and take control over a vehicle while it is driving since dang near every system on the vehicle is electronically controlled now. With the steering, ECM and TCM being electronically controlled and on the CANBUS system the fear is a hacker could hack into the system thru the Onstar data link and take control over the vehicle. If that did happen the occupants would be held hostage and at the mercy of the hackers.

Racing teams even at the lowest level are not using the factory ECM. They are all on Motec systems.

GM just increased security due to over the air hacking potential and increased emissions scrutiny.

These decisions are not driven in any way by the aftermarket.

HP Tuners is offering unlocked ECM or you can send yours in. It’s already broke but no tunes have been written yet.

      OCI, not when but why?

      By Chuck FB · Posted

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      Tranmission stays in Low

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      OCI, not when but why?

      By asilverblazer · Posted

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.

      Stabilitrak conversion to Z71

      By asilverblazer · Posted

      Stabilitrack was a stability control, traction control system, that functioned independently from the transfer case.   Z-71 has nothing to do with the transfer case or differential.   If it does have an AWD system, my memory recalls this being specific to the Denali trim, converting won't be as simple as swapping out mechanical parts like differentials and transfer cases. It will require reprogramming at a minimum. Long story short, not likely worth it.   Pulling a fuse, may disable the AWD system, it might also prevent any other transfer case functions.   However, the AWD case was generally based on the same transfer case you refer to in the 2006 Suburban. If it still has a 4-High and 4-Low where the transfer case locks and splits power 50-50 front to rear, what are you gaining by changing anything? A true-rear wheel drive only, what good will that serve? Not enough to go through the trouble of changing out all the parts.    Generally, all the factory systems will handle a 33" tire and re-gearing. Probably a 35" tire too, if you aren't driving like a caveman. If 35" tires are in the plan...   If you do plan on driving like a caveman or are fully committed to 35" tires, an entire re-think of the build is probably in order. Starting with square one, an IFS front end isn't going to be the best starting point for 35's and caveman driving.

      Oil Consumption

      By PunchT37 · Posted

      1/2 qt over full ain`t gonna hurt $h!t. Most times, a whole qt won`t either. Most have windage trays now. As long as the crank isn`t slapping itself in the oil, it`s not the end of the world.   We used to overfill 1 qt at the track, at race time. Better to have it over full than having the pan sucked dry at 6500 rpm`s.
