Proof that 87 Octane fuel is limiting your 3.6

[bmpcamry09]

Yeah.....another octane thread, but this one is different. This one has proof as to why these 3.6 engines run best on anything other than 87 octane. If you want to safely run 87 octane and still have factory power, you need to be tuned for it. I have no problems tuning for 87 octane for those that want it. But if your stock, your losing out on potentially 40 horsepower and 40 foot pounds of torque when the weather is hot, and the data to prove it is right here. Check out my video. This video is featuring JL Wranglers, but they tune and operate the exact same way on the Gladiator, there are no differences in the ECU tune between the two.

So if you don’t let the timing retard to avoid knocking, are you letting it knock? Or is there a fix for that? Where do we go for more info? My Google machine isn’t helping.

It's not that we aren't letting it retard with the tuning. All factory knock retard strategy is left in place in my tuning for safety.

With tuning, we are optimizing WOT fueling, intake and exhaust variable cam scheduling, and spark table mapping to allow that hot gas to get out of the engine faster and help prevent knock from ever happening in the first place.

Attached below is my tuning guide. Walks through everything to get started.

Thanks. This is out of my wheelhouse.

All good!! I’m a nerd. Lol

This is out of my wheelhouse too. I will say that my jeep feels noticeably less spunky when it settles into true summer around here.

Yep, these ECUs have a table that aggressively pulls timing when intake air temperature goes up, as it does with ambient air temperature increase.

for people that modify their jeep, but might not want to fork over the money for a custom tune, heat management will go along way. Think of ventilated hoods and that sort of thing.

will higher octane help till it gets programmed?? and when you do said program if you forgo hp/tq will it increase fuel milage..
