HO Engines
 
Hey Scott does the 3875 have dedicated tunes for the '02-'04 HO engines and if so what kinds of real world hp and torque gains should I expect? Thanks in advance!

Hey Dave,

Yes, HO support was included. Here are the specific performance numbers and available options for that model:

+48 HP and + 62 ft/lb TQ to the rear wheels when tuned with our 91 performance file.

+18 HP and + 26ft/lb TQ when tuned with our 87 Perf file.

Additional improvements include: positive throttle response improvements, refined transmission shift points and firmness, and improved air fuel ratios offering you the ability to actually get better mileage in the process.

Additionally the program includes additional tuning levels geared for specific tasks:

- Tow tune allowing you the benefit of increased performance while still offering a safe alternative when needing to tow.

- Save tune offering the user a specific mileage option geared towards improved drivability without major performance gains adding even more opportunity for mileage gains depending upon the users driving habits.

The user can also take advantage of the following options:

- Speedometer correction for the addition of larger tires.
- Speed limiter improvements
- a real time idle up feature for those off-road
- Read and clear trouble codes
- Internet updateable allowing updates to be done at your convenience with a personal PC.

Additional downloadable options include:

- Advanced data acquisition (free) allowing the user the ability to watch and record sensor data in real time and create a log of 0-60 and 1/4 mile runs for seeing the improvements the product makes over stock.

- Tire pressure monitoring (free) tuning allowing the user the ability to reduce or eliminate the TPMS sensor light and buzzer when upgrading rims and tires without the sensors or reducing tire pressure for off-road options.

- Advanced transmission tuning ($39.99) Allowing the user to customize each shift point to the setting best sited for the drivers interests from part throttle all the way up to wide open throttle.

So as you can see the product come equipped with a slew of options out of the box and enough downloadable options to keep you busy for quite a while.

Let me know if you have any additional questions.

Scott

Wow those are some impressive #'s! Would you be able to tell me if those are actual dyno #'s and if so, what other mod's were done to the vehicle? I just purchased an '02 Overland and am about to do a K&N FIPK and Kolak exhaust. I'm reading up on tuners for the Jeep to see if it's possible to squeeze a bit more power out of the 4.7 H.O. If the #'s you quoted are actually obtainable, I'll buy a programmer tonight :headbang:

Tests were completed at our in house dyno facility in Florida. Testing was completed using a stock vehicle with no additional mods aside from the tuning.

Additional mods such as a CAI and catback exhaust work well with our tuning and will enhance the tuning from there.

Hey Scott...
I'm currently using the 3875 flashpaq on my 2002 Jeep 4.7L HO. My only concern in using this device is for fuel mileage. Would it be possible to get a custom map, or better yet just the ability to advance timing another 3-5 degrees?

kapytan83 11-19-2013 01:42 PM

With the super chips tuner.. When will it be wise to move on from a canned superchips tune with mods, cai and exhaust are clearly supported and is where I'm at with my jeep (and use superchips flashpaq) but I'm wanting to get bigger tb, will I have to get more personalized tuner to get results from the bigger tb? Or is the flashpaq suffice?

Alex47er 12-10-2013 03:55 AM

Hey Scott after a new tb this would be my next and maybe final mod... Maybe.. I want more info and pricing anyway I could get a hold of any of that without picking your brain too much lol. Thanks
