You have to love the double negatives in the quoted manual pages.

The “may” from the quoted manual pages sounds just like the “may” on ranges web site.

Question for Antonm, are you using Carbyte and if so what do you think?

No, I still have the Range unit, because Holley (parent company of Range Tech) has intentionally made it difficult (if not impossible) to return the units they lied about.

To return the Range Tech unit, it must be in the original packaging and you send to to them for an “ inspection “ , and only after the inspection, that you have no say in, they determine if you can get a refund, minus a restocking fee. Sounds like the business practices of an honest company that stands behind their products doesn’t it. To say I’m disappointed in Holley is an understatement. But I can tell you how much of my money any of their group companies will get going forward.

Apparently Holley does not care about bad reviews either.

Just a bit of emission info, I have a 21 Escalade with the range unit installed and it passed emissions in Massachusetts.

Idk why you’re so bent out of shape about the return policy. Their site outlines returns pretty clearly. It’s a pretty standard return policy too, IMHO.

But if your that insistent, start a charge back with your credit card. That will get someone’s attention at Holley.

Or try to sell it on here. Someone will buy it at a slight discount.

The reason I'm bent out shape is because they changed their tune when it came time to actually return the thing.
It's not "new and unopened" because I opened it, installed it , then figured out it doesn't work as advertised. And they also don't consider it defective (which it is by design).

Here is the actual RMA email I got from them. Read it and tell if you think its from a reputable company, or from a company that's trying their level best to make it hard for a customer to return a product that they lied to them about.

So, they want it back, in the original packaging , they'll inspect and if they determine they lied to you, then and only then will they will issue a refund. But if "they" determine nothing is wrong (i.e. not defective, which they state and is highlighted above) , then they may charge you an inspection fee and sent it back to you, with you paying shipping again.

Lots of "they" do, "they" say, "they" determine stuff that "you" have no recourse in, because obviously "they" don't want to refund a product that "they lied about its function. So yeah, I'm a little bent out of shape of lying Holley's product and their effective "no return" policy.

Obviously "they" are not going to consider it defective because it is working as "they" designed it to (complete with 0% throttle DFM still functioning).

That’s SOP for returns. For all they know you could have let the smoke out or bent all the pins or destroyed it in some way. Some electronic companies won’t even consider returns—you open it, you own it.

 

[PPV_2018]

I don’t see anything out the norm here. Yeah, a lot of companies have the return policy tailored to the company benefit to prevent customers from abusing that policy.. which happens every day from a certain type of scumbag clientele.

Lesson learned: read return policy before purchase. Moving on now …

Reviews??? Where is there a place to leave a review?

Sounds great, lets make an SOP that makes it impossible for customers to return a product that they were lied to about. Now lets make a device we claim will cure cancer that plugs into the OBD2 port, and when it doesn't, sorry, our SOP for returns doesn't allow you to get your money back from the product we blatantly and knowingly lied about.

I should start referring to Holley as "Sentinel Capital Partners" , the investment firm that owns Holley and all of its brands (like the Holley brand Range Technology).

[Scarey]

I’m pissed too. All the cylinders all the time. It’s a lie.

You, sir, are out of line. I was merely stating many companies have the same, or much worse, return policies. Do you live under a rock?

Further, you choose to make it personal. I have had cancer in the past. I have relatives die of cancer. With your comment, you have shown you are a bitter person who only cares about yourself and how you were “wronged” and wants to make sure all of us know it.

Do you have anything useful to contribute?

Pointing out flaws in logic makes me out of line. And mentioning the word cancer makes it personal to you huh. You'll probably never guess just how much your opinion matters to me. Go cry in your safe place snowflake.

How about some facts to contribute:

Fact: Holley/ Range tech blatantly and knowingly lied about what their device does.

Fact: They make it so once the customer figures out they've been lied to, they can't return the device.
...

 

[PPV_2018]

The only person crying here is you. Did you read the return policy before purchase?

 

[Antonm]

Honesty no, because I don't return stuff very often.

I did however read the description of what they said it does and it said "all cylinders, all the time". Which I later found out to be a lie (and they knew it was lie before sending out the very first device).

Having been a long time gear head I mistakenly assumed Holley was still a reputable company (I've used their products for literally decades). Apparently since they're now owned by Sentinel Capital partners (a private equity firm, because private equity firms do great things in the automotive aftermarket industry,,, just look at what private equity did for Wheel Pros and all their brands like Hoonigan and 4 wheel parts) they are now Holley in name only, and are just another company selling stuff based off brand recognition, from a brand they purchased.

To be clear, all I want is the product to do what they said it would do, nothing more, nothing special, just turn off the DFM. And YES i am 100% going to tell everyone I can, every chance I get, what a rip off, lying, and under-handed company that Holley (or more correctly Sentinel Capital Partners) is now.

They ripped me off, and yes that pisses me off. Best I can do is hope that I can help to prevent them from ripping off the next guy.

At least you were honest about that, which i respect. So fair enough, but if you did not read the policy, it’s hard to criticize it after. If the policy seems sleazy from the start, there may be something amiss. It’s different if the policy says something else and they refuse to honor it.

May i suggest selling the range unit to someone else, with the disclaimer that it does not actually disable DFM of course, and put the proceeds towards your next mod:

(If you can’t laugh about life you cry)

 

[Antonm]

I have a friend (well, more of a friend-of-a-friend type acquaintance really) that's in the electronic billboard business. Wonder if I could use our mutual friend as a go between to get a discount on a months rent on one of those big roadside electronic billboards,,,now that would be funny.

[RG23RST]

'The conditions below MAY be reasons for inhibiting deactivation'
'Decel Fuel Cut Off is active'
As in, MAY, or may NOT.
Any English teacher or proofreader will understand that DFCO might allow cylinder deactivation,
or that some DFCO events might also coincide with some cylinder deactivations.

DFCO and cylinder deactivation are two separate different UNRELATED things.
However, they are NOT mutually exclusive.
(I.E.: I MAY achieve turgidity even when NOT distracted by the thought of Milana Vayntrub in a bikini.)

Antonm, DFCO does not cause cylinder deactivation either.
Their occurrences can overlap without one causing the other, however.

Since Antonm is not going to win any money by RG23RST being wrong,
and RG23RST is not going to win any money by Antonm being wrong,
ultimately, Range has already admitted that they did NOT deactivate 0-cylinder mode,
RANGE IS WRONG, and Milana Vayntrub is gorgeous.

I'm really not sure what to say. Either some of y'all are being purposely dense or have ulterior motives. Again let me be clear: There are no lifters deactivated during coast-down. None. GM documentation states that and scan tool data confirms it.

You are misunderstanding the text in attempting to be right instead of taking the L and moving on. DFM or if you want to go back to the OG "skip fire" doesn't work like AFM. You're starting from all 8 cylinders firing and working backwards. DFM operates from a firing fraction (or firing density) of 0 and goes up from there to 1 which means all cylinders firing. The engine controller is constantly calculating how many cylinders it needs to fire to meet torque demand, not how many to disable to "save fuel." "May be reasons for inhibiting deactivation" in the context of the technical data is essentially a re-hash of the enabling conditions with some additions. An "enabling condition" of DFM is that the engine not be in DFCO......

In theory of the 29 firing fractions in the engine controller there is a firing fraction of "0." HOWEVER this is where the logic de-couples. In the interest of NVH, emissions and so on GM does not actually use DFM in a 0 firing fraction mode. The minimum they have in the logic is a FF of 1. In addition, no one cylinder is deactivated for more than 20 cycles continuously for longevity and emissions purposes. This is directly at odds with the concept of deactivation all 8 cylinders on a long coast down. To help recover the pumping losses that would be gained from using that mode you'll notice throttle valve actuation when coasting. Opening the throttle valve during DFCO greatly reduces the pumping loss of pulling vacuum by a closed throttle.

See below for graphing of a minimum FF of 1.

I don't have anything to do with Range or Carbyte so I don't know why they included the marketing information talking about "0 cylinder mode." It only serves to confuse people. If you want that coast down behavior gone you can run in manual mode and enjoy your engine braking. Might save 1mm on the brake pads over 50k miles, idk. Probably waste a whole lot more fuel.

 

[Scarey]

I have no idea what you just said. Your anger is interesting. Why don’t you enlighten us with your engineering credentials?

This whole talk about return policy is immaterial. Range misrepresented its product. In other words they lied.

 

[Antonm]

Again let me be clear: There are no lifters deactivated during coast-down. None. GM documentation states that and scan tool data confirms it.

If this is true, then that is fantastic news .

The reason I say "if its true" is I've spend way more time that I wanted to reading about this in every corner of the internet I could find (mostly because I didn't want to believe that Holley lied to me and ripped me off, you know,,, the whole denial phase thing) and you are the first ,and only, person that thinks this.

If you could enlightened me on want scan tool you used to verify this I'd appreciate it as I've been eyeing a new Topdon scan tool (the topdon artiDiag pro bidirectional to be exact, seems like a heck of scan tool for under $500) but if there is another one that could read this I might switch and buy that one instead.
