AFM disabler

[wsteele]

Those were my goals too, and a Stage 1 cam would still serve those goals. What sent me over the edge toward the stage 2 was the videos I found of that cam idling, and the conversation I had with the guy from Brian Tooley on the phone after discussing how I use the truck and my priorities. The stage 2 is beastly, but still has decent daily driver manners and is a set/forget package that should live a long, reliable life. The stage 1 is a little less beastly and has OEM-like manners.

I believe the pressure relief valve opens at 55 psi.

Thanks for the info. I just sent BB an email with some questions. My thoughts are maybe I do the AFM delete tune first and then do the lifter/cam delete with a follow up tune to dial everything a little. My main concern at this point would be making sure I will pass an Idaho emissions test after all is said and done.

I know I am probably being overly optimistic, but a straight lifter/cam swap doesn’t sound too daunting. On the other hand, having to spend a lot of time on that cold garage floor (if I dropped the oil pan) might have me looking for a shop for all this stuff.

The problem with this "can of worms" is that none of it is technically difficult or requires a lot of skill. It is the domino effect of everything.

To remove the timing chain, you need to remove the oil pump. To remove the oil pump, you need to drop the oil pan so you can get to the bolt holding the pickup tube to the pump. To drop the oil pan on a AWD Denali, you have to drop your front Differential. To drop your differential, you need to loosen your steering rack. I think somewhere in there, the brace that goes between the control arm mounts comes out as well. Kind of a leg bone connected to the hip bone thing. None of it is complex stuff, just a pain to do whether you're on jack stands like I was or have a lift.

Yep, I wonder what is in me to be so optimistic, when I know the truth. I mean decades of experience and I still am expecting push, pull, click, click, that was easy. Maybe I will just wait...

Just an update, I got a response from BB and they can't opine on the ability for me to pass Idaho emissions after any software AFM delete and tune using their setup (regardless on whether I have done the mechanical AFM delete or just the software delete). Probably just a legal exposure thing. They firmly stated, it is for "off road use" only.

Maybe I will spring for one of those clone Tech 2's and do the SW AFM delete myself. It wouldn't be bad to have one around for the long term. I have to say, looking at the video training for the Tech 2, seems pretty primitive compared to what is available today, even just the $25 dongle gadget I got for my iPhone. Of course, I can't do any of the ECM changes with the dongle gadget...

I'm pretty sure a Tech2 (or clone) can't disable/enable AFM. I know I haven't seen any menu options for it when using the Tech2

I have been going through some of the training videos and so far no joy as well. Seems kind of strange as it might be something you wanted to do during a diagnostic exercise at least.

I got another Range device today, so now each of the Hoes has one.

I have had mine in for a few days, pretty seamless. So seamless, I will probably forget it is there when I go for my next emissions test...

I am looking at the Diablo products, to see if they can do the diagnostic telemetry stuff I would like (real time parameter monitoring, etc.), as well as turning AFM off. If so, I may spring for that and sell my Range gadget.

I have just about made up my mind I am not going to do a mechanical delete as the only way it makes sense financially is for me to do it myself and right now I just don’t have the energy to tackle it. If I do get something like the Diablo Predator to turn the AFM off, I think that will be it until my hand is forced with a reman.

At least one of the usual suspects in the reman world is offering AFM deleted remans (either Jasper or Fraser, can’t remember), but that would be a good option if and when a new engine becomes the cost effective choice.

I’ve had the range device for almost a year now. It gives me a little peace knowing I shouldn’t have issues since I’m doing regular oil changes as well. I’m thinking of getting a Diablo tuner though.

I just sold my Range device. I got a Diablo Predator and will turn my AFM off as soon as my testing on the effects of the Disabler on drive cycle monitors are done. I am at 350 miles and about 11 cold starts, still have one monitor in "not Passed" status. It is the evap monitor, so I think I would pass emissions in any case.
