0-60 in 4 Seconds - My 2.7 Bronco Performance Modification Thread

[MWILD]

Oh, and I installed a catch can because why not.

Also picked up some sweet ZFG merch. Gotta love the BetaTester decal.

Did you install an ethanol content reader or just going off a tune/mix ratio. Locally in my area E85 is hard to find close to it usually it’s only 50~78% max.

My current tune is full E85. No need to mix with 93. The local Sheetz is always around 70%. Not great, but better than nothing.

Quick update. Working with Adam at ZFG to get the E85 tune dialed in. We ran into some misfire issues, but hoping we can get them rectified soon. That said, a 12 second Bronco is more realistic than you think. There’s still more room in the E85 tune and she’s already scooting with up 21-22 PSI of consistent boost.



My best 0-60 and 1/4 mile thus far.

That is crazy for a 4x4!! I burned a tank of E85 mixed with 93 (guestimating obtaining E30), and there was a noticeable difference in power. I had loaned out my Dragy so I didn't get a chance to log it. Keep up the good work MWILD!!

I just got a Dragy. Waiting for it to arrive. Gonna buy the ZFG tune in few days to a week and give it a go. I'm on 37in wheels so we'll see how much slower I am ha.

Awesome! Looking forward to seeing your results! Love the ZFG Tune.

I mix 4 gallons of E85 with 11 or so gallons of 89 midgrade. My math says that's about 92 octane so it's a tank of premium for the price of regular. No aftermarket tune yet buy I might do a piggyback tune. I'm looking into 35's off a member on here so I might need the umph to make up for the weight an gearing loss.

@MWILD How are your rezeppa joints holding up with all the rippin hole shots I'm sure you are doing.

Haven’t toasted them yet, but don’t jinx me

Never thought a Bronco would be getting those numbers with just the mods you've done. Starting to really think I purchased the wrong version. Also as much fun at the 7mt is I know that is slowing me down a good bit too. Need to really learn to launch it and stop lifting on shifts.

These are awesome results. Do you lose any of the OEM functions with this? Keypad entry/over the air updates/ etc?

Do you still run the procal? or is ZFG handleing the transmission tuning and engine tuning as a single standalone option?

Super impressive results.

The 2.3L is super capable, so I wouldn't count it out. Open up the exhaust and wait for custom tuning and she'll fly.

I'm not sure what's done to this Bronco besides the exhaust, but it puts down some super impressive numbers.

Thanks!

No OEM functions to my knowledge are lost and you shouldn't have any issues with your keys and keypad. All of that is handled when ZFG uses FDRS to program PATS.

ZFG includes transmission and throttle response tuning as well. Normal mode shifts faster, but is not harsh. Throttle response is better, but not by much. Feels like a normal Bronco, but with better transmission shifting and when you get into it she moves.

Sport mode is an absolute animal. Throttle response is much improved and the up and down shifts are hard and fast. The trans take a little bit to relearn, so it's a little clunky for a bit. I've chirped 2nd gear a few times... and don't launch it in 2WD because you'll leave tire marks for 20+ feet.

Sand mode has been converted into Drag mode. The biggest change is raising the shift points a few hundred RPM. You'll get the best times in this mode, but since it's locked to 4H I would recommend it for only going straight line runs - I also just had the tuner lock sand mode to 2nd gear launches. 1st gear puts down great times, but it's very violent and I feel like I'm gonna break something if I keep launching like that. 2nd gear is just as fast and not as much drama if you leave around 2.2-2.5K RPM.

Anyway, I no longer run the ProCal tune, I just use the ProCal 4 device for the extra gauges. The ZFG tune replaces the need for anything else.

Keep in mind, the E85 tune I'm on now is awesome, but the gas mileage sucks. I'm averaging around 13 MPG around town with normal driving - No WOT runs. I personally don't care that much, because I don't have a long commute and don't drive much. I'm saving money at the pump going w/E85, but it isn't readily available everywhere. I have a station 2 miles from my house, so I plan to run it for awhile. ZFG thinks I should be around 400+ WHP with E85 when the tune is fully dialed in (Not there yet). I do plan to dyno it and take it to the track in the future.
