"REDUCED ENGINE POWER" w/ hypertech???


Recommended Posts

Posted

Hey everyone! I've been reading along and enjoying everyone's posts here for the last few weeks so I decided to join in on the fun! :bs: I'm hoping maybe someone will have some insight on this topic. I just got a new Hypertech power programmer III #30022 for my 2005 Sierra 5.3 2wd. After installing the hypertech program AND also when reprogramming it back to stock I get this message popping up for maybe 3 - 5 seconds, just before the programmer begins the "writing" process. The message reads: "REDUCED ENGINE POWER". This was kind of shocking since I was hoping to INCREASE engine power through the programmer :ughdance: After I programmed it the first time I took it for a spin and I can notice better acceleration and shifting, but the message still worries me. Anyone heard of anything like this or had the same thing happen to them when reprogramming the ecu? I am using 87 octane and the only mod I have so far is a Volant intake. Thanks in advance.

EM.............I also am running the Hypertech3.

Sounds like a software glitch in the programmer itself..............

 

I would try disconnecting the battery cable and see if it

clears the REP message.............. If not call the Hypertech

800 problem # in your instructions for assistance.............geo

i also have the programer and recently had a service 4wd message come accross the dic and took it to my dealership and set the truck back to stock so they could fix the service 4wd message, afterwords i put the hypertech back into the truck and noticed the reduced power, service 4wd and a couple other messages, i called hypertech and told them the story they said that it is a defalt the programmer does pulling all the possible codes from the dic and displays them so they say its normal. i put mine on 93 octane and have shift improvement, along with the top speed limmiter bumped to 110mph honesly havent had any issues with it.

Thanks for the replies sonjaab and sablowme! I'm wondering if other programmers are causing the same message to display. Anyone use a diablo or superchips programmer?

Emit I have used that programmer and on my 03 Tahoe it would show all those messages but they would go away after the truck was programmed. I was worried the first time but it does go away after the programming is done. I don't think I'd worry about it unless it was displaying after the truck is programmed.

I have the Predator, and mine did the same thing. It is just a programming cycle it goes through. Nothing to worry about.

Mine displays the same message, it mentioned something about this in the manual so I wasn't surprised when I saw it. You read the manual right?  :thumbs:

 

 

 

 

I read the manual at least a few times over and didn't see anything about this message, but I guess if everyone seems to agree that this is normal then I won't need to worry about it anymore. Just glad I'm not the only one and that no one's reported any horror stories of ecu failures or any other problems. Thanks for all the input! :lol::thumbs:

    • So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.
    • I haven't seen diesel for less than $5.30 anywhere in my area
    • The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".  
    • $3.69 for 87 octane.   $4.24 for Diesel in town.
    • On the subject of OLM, Gm's OLM tool may be more "informed" than others brands. I recall OLM's in mid-2000's Chrysler products literally counting down a set number of miles. That's all the OLM appeared to be.    I would actually expect GM to be able to explain the parameters that their OLM takes into account from a high level. No, I would not expect them to disclose their software coding or data analysis around their parameters.   So we're talking about two different topics, so to continue the subject on the other one, I'd be curious to know how much "standard particulate matter" in fresh oil is able to be filtered at first start by a fresh oil filter. How much particulate matter is enough to "matter"?   I.e. how much of a "lever" do we think this equates to (variability in particulate content, in fresh oils, between different makes/brands, some which filter less, and some that filter more).   We can say that more particles = more wear = shorter engine life as a logical statement and use that data with a little marketing to scare people into selecting a more refined/filtered oil. Using a similie, is this like deciding to forego two alcoholic drinks in a lifetime because we're worried about the potential impact on lifespan? Are there numbers which translate the ISO test results into a quantifiable increase in wear for a given engine/use case?
