Those of you that have turned off AFM , are you still glad you did and are you still saying that gas mileage has not really changed? Are there still some people out there that wish it was turned off. I am still on the fence about it, but I hate that 8 to 4 and 4 to 8 chug/surge while cruising. I am thinking either AFM has to go or I will have to go back to stock modules where AFM is smooth but everything else sucks.

I have mine turned off now and it feels a lot smoother now...As for mileage, still on the first tank after the tune and I'm having trouble staying out of WOT haha...

I plan on having Justin turn mine off when he comes back to my place in Sept. If I had a different type of driving environment I may keep it. But there is soooo much stop and go stuff around here that the benefits I get from it are about Zero. Most of my long highway trips are with a trailer when I don't want the AFM anyway.

 

I don't dislike AFM, but I don't get a lot of benefit from it daily and I don't want it on while towing. Plus, I plan on eventually putting exhaust on my truck and I don't want to worry about the resonance during 4 cylinder mode.

 

It has helped me on a few long highway trips. I in all honesty have got 21mpg on a 150 mile trip driving 65-70mph. That is not the norm and I'm sure the stars were aligned just right, but I did. My AFM was on a lot during that trip. So it can help, but for me it really doesn't do much for 95% of my driving.

When does he return? is it for another tune session?

Yep, another tune session. He will be back Sept 4-6th.

It's been off since I first got my Black Bear tune, I don't miss it at all.

 

 

+1

 

And I have seen exactly ZERO drop in MPGs.

I did a mileage check on/off and didn't see any difference, so it's been off for more than a year now. No issues and glad it's off.

Thanks for the input guys. I am in the process of discusing all my options with Justin now. He has done a great job on the tune and his customer service is second to none. I just hate that AFM transition. He has told me he can smooth that out but I would have to sacrafice some of the benefits of the tune. So I'm thinking, why not just turn it off, especially since there seems to be almost no loss in MPGs. Was looking for opinions here and got some. Thanks Again.

I REALLY wish we had the option within DIC to just turn if off ourselves.

J man67- on a related topic- I'm sure I missed it on another thread, but what ever happened with your ticking lifter situation? Went away or got replaced?

Get rid of the AFM....You won't regret it!

Its just useless on these trucks.

      I have thought an EV might have some practical value in extending the life of the ICE members of ones fleet. Now....I'm convinced of it. I've been letting my better half access Raven (Mitsubishi Mirage) for her needs while Dizzy has been in the shop. Being the fuel freak I am and given the fact Raven is capable of over 60 mpg in clean air on a warm day I was taken back by the wife's ability to take a car that had used a half a tank of gas that to that point had returned a value of 57 mpg and return in with a decimating 51 mpg for that same tank in that same day in a 15 mile round trip of short hop errands and a stop in the drive through at Micky D's.  😱   Trust me on this. It would take the remainder of that tank driven on the highway to return that tank to just 54 mpg. This is not a Mitsubishi issue. This is an ICE issue that is magnified in vehicles capable of such high fuel economy values. On a percentage basis your 1500 does the same thing. Short hopping an ICE consumes a good deal more fuel and in doing so provides zero additional useable outputs. That entire volume of fuel is wasted in diluting the cylinder walls oil films, creating crankcase moisture and acid content and the resultant wear.    Enter the SLATE. All of that is avoided and the ICE's advantage in range and made useful at reduced wear for your ICE!   Kind'a cool.

      Back in the day people would buy cars based on performance. The charger posted does 0-60 in 3.3 seconds. And it’s fully loaded.  It has a decent warranty and will fit most anyone’s needs. Remember the original Hemi? 90 day warranty. 25K mini truck or that car? I’d go with the car. It wouldn’t fit my perimeter. If I could just talk my wife out of her Genesis. It would be perfect for her.

      Let's pivot this back. Someone said they wanted pictures.   Even better, there's already video. Pre-prod prototypes are already on the road and they're letting the press drive them.   JerryRigEverything did a good review. I really enjoy his content and EV adventures, so I was thrilled when he had the chance to review a Slate:

      The Charger EV was stillborn. Wrong car at the wrong price for Dodge's intended audience. Now at a good price with fire-sale discounts, and still not selling, it's still very much the wrong car. Again, Dodge's intended audience. I believe a lot of Stellantis' EV blunders were all under Tavares' regime at Stellantis...the board convinced him to move on. Neat car, just wasn't received on the level that would sustain mass production.   Dodge is headed in a better direction for its core business. I didn't think there was anything left to get excited about re: the Durango after its 15 year run, but they're just now releasing a 392 version that should price out in the low 40's. Nicely done. I'm not sure I would touch anything Stellantis makes with a 10' pole these days, but the Durango is still mostly parts designed like 3 parent companies ago so maybe it's still OK?
