Going out on a limb here....... It is no secret the number 1 limitation of getting our Jeeps tuned is the ECU unlock process. The busier HP Tuners gets, the longer the turnaround is for this service, and it sucks frankly. I have been doing A LOT of research into the software and hardware...

I lock them just to keep people from fat fingering something but can unlock on request no problem. I’ve got nothing to hide lol customer paid for the tune I’ve got no issue unlocking it.

It is all inferred through oxygen sensor readings and the toggle for flex being actually turned on. The e85 mapping is already there in the tuning software it just has to be toggled on. Can’t just fill up and it changes itself unfortunately. I don’t really plan on supporting it at this time...

I don’t have any stock 0-60 videos but I do have a tuned one here, although this was made pre dyno and my latest stuff is a bit better. Also a Wrangler and not a JT, but you get the point

In part throttle driving, under 4000 RPM I routinely see increases of 20 TQ or more with 87 octane and 30-40 with premium fuel. I can command higher torque demand, more spark timing, and more VVT intake advance in those lower areas with premium fuel than I can with 87 in the tank, but both are...

There was also no correction factor applied to my results. It was raw and real and in a 100 degree room with up to 145 degree intake temps. I’m just hard on myself lol but I’m glad I had extreme conditions because that’s what these jeeps go through.

At part throttle under 4000 with 87 octane you can expect 20-25 TQ extra available over stock. With 93 octane I’ve seen 40 TQ available extra under 4000.

Today was the long awaited trip to the dyno. This was with my JL, but JT will be the same, exact same tuning between the two. Overall goals were: -10 HP/10 TQ on 87 Octane -30 HP/30 TQ on 93 Octane -Smoothing the torque curve and getting a more flat powerband under 3500 RPM -Optimizing WOT...

You talking about this thread? If so I’m not sure what tire/gear has to do with it, but I’m 3.45 with 31.5s. Bone stock currently.

OP, I am one of the only people tuning this platform who is also active on the forums, and potentially the only one who is truly custom and requires datalogs to make sure the tune works for your Jeep. Check out my big thread on the JL site for all the details, I have one here too but JL side is...

I understand where your coming from, and not trying to make this an infomercial. Definitely don't feel threatened lol I'm as easy going as they come and I'm sorry if you misinterpreted my tone. But you said "it's not simply changing a throttle input of 20% to 30%, or whatever, it's commanding...

In an effort to back up what I mentioned, here is a breakdown of the pedal tables, and a demonstration of what pedal manipulators do to your Jeep, for those who like good data.....again, there is no substitute for good tuning.....a few of my Gladiator customers (@zuki_dan @DronePilot) had a...

The PM and PC and similar devices are not commanding more torque. The commanded torque table on the GPEC2A and GPEC5 ECU can't be modified without tuning or else you'll go into limp mode immediately. See my below post for more detail as I decided to put some visual help in. Throttle controllers...

That lag/hesitation has everything to do with the variable cam system and nothing to do with the trans, tune is the only fix

It is usually to stabilize air conditioning high and low side pressures. If your HVAC is turned on, this is why. It probably won’t do it if your HVAC is off.

I'll play devils advocate..... I'm a 5W30 full synthetic every 4000 miles kind of guy. Its been around 100 degrees F lately and I just feel better knowing it's in there. Mopar or Purolator Plus filters only. Purolator Plus has great statistics and are affordable. This all said, I'm VERY...

Nice! The formula I use to get EQ commanded to display properly is: -Stoich FA value from the tune itself (usually .0720) divided by FA Desired + FA Enrichment. Seems to be the most reliable for tuning by lambda. The cool thing is that FA stoich value from the tune can varry based on ethanol...

I haven’t played with e85 yet but these appear to have full e85 capability out of the box just a single button needs to be clicked to make it that way. All the spark tables and o2 sensor monitors are defined and in place. I plan on testing the E85 side soon.

Ahhh I see. Yeah commanded AFR. Old school. If it’s anything like the EQ commanded it actually requires a Mopar math formula using FA Desired and FA enrichment as multipliers to get the true value. I don’t have the math handy as I’m riding rides at Busch Gardens with the family on vacation at...

If you are logging your vehicle with some kind of generic PID that references lambda or commanded EQ with a value of 1.0, your device could be converting that to 14.7 on your logger. Which would make more sense.
