2021 4xe Rubicon
I know there are a lot of FORM threads but those are about getting out of the mode. I’m here to ask is there a way to force this on?

One thing I’m not a fan of is how the 4xe almost operates as two separate engines. It’ll start off in electric then if I floor it the gas will kick on. But it’s hard to find that sweet spot where both are running at the same time and giving full torque while maximizing fuel efficiency.

I just recently went into FORM mode as I hadn’t filled up in over three months. Been in FORM for about three days and let me tell you, the 4xe was the funnest to drive during this time. Both the gas and electric work at the same time. On the hybrid page it was generally around a 3:1 ratio of engine to electric and sometimes 50/50. But my mpg was always around 25-35 and the power from the pedal was amazing. It was a blast. Almost felt like a 392.

I’ve tried in the past to get that right mix and there was a thread on here about using M8 mode to get the best mix. However M8 is at its nature manual so whenever I use M8 my mpg is always single digits.

But in FORM it was always above 25 because the system would shift at optimal times. So in a way FORM is like an automatic M8 mode if that makes sense.

Absolutely loved the torque and power in FORM mode and now that it cleared I’m back to being electric most of the time. Would love to just have an option to FORM on those days I just want to haul ass.

Again, apologies to those stuck in FORM and trying to get out of it but it is truly a joy to drive while in FORM and I wish I could get back to that.

Haha, I wonder if your terrain is a lot flatter than mine and the ECM is learning differently.
On 37s mine will fire up ICE about half the time in hybrid without heavy throttle.

Maybe playing with a pedal commander?

I also have 37s. I just drive street so even terrain.
Haven’t thought about a pedal commander. Is there one compatible with 4xe? And would I be able to turn it on and off?

I havent personally used one, but I believe they are adjustible live. They just intercept the accelerator position and modify, so I would assume it’d work on ours, but it’d be good to check with them.

Have been stuck in FORM for about a week and totally agree with OP. The 4XE is a beast in this mode. It would be interesting to see Jeep roll out a "Sport mode" or something that has the car behave like this on demand.

Seriously that would be awesome.
Between tazer and pedal commander I have to believe we can force this mode on command

Yeah you bought a hybrid....

There isn't that spot. Maximum fuel efficiency is on battery only

So now you know but the way to get what you want is this. Drive around in 4auto so your not torque limited in 2H. Also drive around with ESC off for those sweet tire chirping launches at red lights. When driving normally just let hybrid do its thing but if you want to pass or launch at the light hit your E save button to turn on the ICE and mash the throttle for more seamless power delivery (FOR THE LOVE OF GOD LET YOUR MOTOR WARM UP BEFORE REVVING IT TO THE MOON, actually I don't care you do you.) Then back to cruising hit the hybrid button again.

Yes on a vehicle with 375 lbs of horsepower and 470 ft lbs of torque. So I was expecting a little more power than driving a 5,000 lbs prius

So I did what you said and while it is an improvement, it's no where near what the power I had in FORM. I even had esave setting at hold save instead of charge, so any extra power would be available as well.

If driving in FORM was 10/10 brute power, I'd say your settings was around 7/10 so its something, but not quite there.

Have to imagine there is a way to unlock this setting since it's hidden in the programming anyway.

You were complaining about the transition from the battery to the ICE.... Yes, a hybrid, power isn't in your scenario here.

um ok. Did you ask Jeep for the 2.0L turbo badge? It adds 5hp. Butt dyno feels more like 22.7hp.

If you didn't catch my sarcasm there, there is no extra power in FORM. It's in your head. But if you don't know how to launch the Jeep off the line this will make you giggle a little (yes I'm serious this time)

  1. 4 auto
  2. Traction/ESC off (hold the trac off button for 5-8 seconds)
  3. Press firmly on the brake with your left foot.
  4. Slowly lean into the accelerator to bring the RPMS to 2,000 and hold those rpms for ~5 seconds (called brake boosting)
  5. At the same time release the brake and mash the accelerator
  6. Giggle

Are you sure it's more power you're experiencing and not just less throttle lag since everything is already up and running?

I tried every scenario. Nothing comes close to when it was in FORM

Positive. You watch those 392 YouTube videos where they get thrown back when they accelerate? It was similar to that.

I drove in M8 so the engine was on and the lift off was not the same.
Even when in hybrid and I account for the throttle lag, it's not the same.

I'm guessing most people when in FORM are more upset at being FORM and are not actively driving it around. Next time you guys are in FORM, punch it and see how it feels, and compare that to when you are out of FORM.

LOL OK whatever man.

I'm also not the first person to experience this

1,000x yes on the sport mode!

I posted this elsewhere but I had gone quite a while between fill ups and the Jeep went into a "fuel and oil refresh mode" where the engine ran along with the electric while in "D" and did not shut off until the vehicle shut off (I assume this forced engine mode burns off contaminants in the oil when the vehicle thinks the ICE has not been run enough) . The all Electric mode was not available during this.

Absolutely the MOST fun I've had diving it in the 4+ months I've had it. Certainly not the most economical but the software did a fantastic job of blending the 2 power sources. Electric torque to launch the Jeep then a tapering off of electric while gas took over. Instant power without the ruckus that ensues when you floor it when the engine has been off. Easily doubled the battery life when blending the two.

You can sort off get this mode by throwing it in manual mode but it sucks in traffic. I am a manual guy at heart but the Jeep is NOT a vehicle that begs to have it's automatic driven manually. It's so tedious.

I would for sure pay for this mode if Tazer did this. I would think they could figure out a way to trick the car into this mode. And eSave is not the same at all. With that you're back to ICE only and don't have any of the benefit of the electric torque/hp.

https://www.jlwranglerforums.com/fo...in-progress-engine-running-stuck.82985/page-3
As someone else mentioned, it actually drives pretty well in FORM mode and gradually uses the battery to enhance power and efficiency
In fact there's a whole thread about people wishing there was a Sport mode on the 4xe
https://www.jlwranglerforums.com/forum/threads/love-my-4xe-needs-a-sport-mode.80077/

So all I'm saying is that yes there is a more noticeable power/torque increase when in FORM mode. I also tracked the engine/electrical output on the hybrid page and it used both efficiently, and my MPG was always between 25-35.

I felt the increased power in FORM and am trying to see how I can get that back again because no matter what other settings I use (4H, ESC off, e-save, M8, etc) does not come close to how great it was running in FORM

2021 Wrangler Unlimited Rubicon 4xe
New here... have had my 4xe for about 3 weeks and experienced what I think is FORM this morning. Loved how both engines were working in tandem. At least, that is how it seemed. I had been driving in all three basic modes (Hybrid, Electric & E-save). I like the electric as I believe that is where the true "power" off-the-line comes from (correct me if I'm wrong). It just seems like better acceleration initially. When I was in E-save or when electric was depleted and using only ICE, the response time and acceleration to highway-speed suffered.

I know we cannot use the screen as an accurate gauge of fuel efficiency but the FORM "felt" better (*performance). Also, it balanced the amount of electric power used with gas so that I was not low or "empty" when I reached work. That means I do not have to pay the premium kWh prices at a charging station and can wait for the ride home where I can charge the battery for 1/2 the price (at least).

When this FORM kicks off, I am going to try the M8 and see how that does. If it works that way, I'll be able to better manage the type of energy used so that I have better performance*. I'll also be able to maximize cost savings by not having to pay premium electric rates. But, as many say, I didn't buy the 4xe for the fuel efficiency (nice benefit) but for the increased hp and torque.


*Performance to me means a better quality drive, Not efficiency. Performance has multiple meanings~
  1. the capabilities of a machine, vehicle, or product, especially when observed under particular conditions.

  2. the extent to which an investment is profitable, especially in relation to other investments.
