I bought my Flashpaq from watching Jpops thread written a while back. He definitely did the home work and it was the right call for me. I paid $315 and had I known the difference it would make prior to purchase would have paid $415. I'm going to go play with my SC now...

 

shit - i knew my sc tattoo was probably taking it too far.

sc here and am very happy, but in the interest of full disclosure, i've never owned any other programmer/tuner, so i have no basis for comparison.

i understand the desire to see something on paper. but it's similar to seeing something on a website, or seeing a posting on this forum - it's nice to know, but i can't really feel comfortable until i experience the device for myself. so... buy both or all and test them. experience them for yourself and return the ones you don't like or meet your standards. if a manufacturer doesn't accept a return you have to wonder why.

bottom line - if you have two programmers and one has better dyno reports on paper but the other feels better to you, which would you stick with?

 

I'm reminded of one of the classic lines from Tommy Boy.

I can get a good look at a T-bone by sticking my head up a bull's ass, but I'd rather take a butcher's word for it.

 

Pop, it has already exceeded my expectations by a considerable amount, especially given the mods I've done to it. I was pretty familiar with the "minivan" motor and I would have to say it is definitely over-performing for me. My primary concern with an offroad engine is reliability, the track record for this motor, often in a totally unmaintained state, has been exceptional for co-workers in the Chrystler minivans.
Add a bit of power with the RIPP blower, and it'll be perfect. It just doesn't seem intake/exhaust/headers/gears are enough to do the job on a lifted heavy little 2 door running the heaviest of the 35 MTs & beadlocks. It's more of an aerodynamic thing, because the Jeep is terrific under about 55-60mph.

My primary question on the Superchip programmer concerns low rpm (below 2.2K) driveability/torque, it is superb, excellent, fantastic, on the Hypertech.
This is a tremedous improvement over stock on, as well as off road. In town it really reduces the need to shift, and makes the gears very long legged. Offroad, it's very easy to manipulate the throttle to get just the amount of power you want.

 

I've been running the tow setting on the SC as it suits the way I drive and greatly improves where I thought the vehicle was a pig. I'll probably switch things up for a long trip I have coming up where I'm sure to be spinning the motor a little more and not as concerned about rolling away from a stop light or sign.

 

I'm only going to post one more time about this, the SC vs the hypertech are night and day difference in power, I NEVER FELT A DIFFERENCE IN POWER WITH HYPERTECH SPECIALLY ON THE LOW RPM RANGE AND OFF THE LINE. WITH THE SUPERCHIPS I IMMEDIATELY FELT THE DIFFERENCE JUST PULLING OUT OF MY PARKING LOT, LOW END OFF THE LINE IS HUGELY IMPROVED AND THATS NOT WITH FLOORING THE SKINNY PEDAL AT ALL, NO WHERE NEAR IT, I DONT DRIVE MY JEEP LIKE THAT WHEN I'M NOT HITTING A PUDDLE HAHA.

Its pretty damn funny hearing some people doubting it, but yet EVERYONE thats had both say there is a BIG difference, people who drove in someones jeep that has one say they want one now, but we are just lying

You know what keep on driving around with the Hypertech its wonderful

 

GOOD GRIEF! Please don't bother yourself to post again!

Just asking about the low end driveability.

Others on this forum with the Superchip have commented "slow speed drivability like cruising a parking lot in first or second gear is much worse. The throttle open right off idle is very abrupt, same when you lift off the gas and the throttle closes. You get a jerk city ride with the 6 speed."

 

Those comments were from a person who had a single day with their newly installed programmer. Although I haven't experienced the same, I've seen some very limited similar comments posted here and seemingly up against the PCM relearn process. In the one or two cases I saw posted the remedy was a few miles logged and perhaps a days worth of driving.

There are certainly lots of causes to this. Remapping of the A/F mixture, manifold pressure, throttle position, knock sensors and backing out some of the timing advance. That's a lot of items to be straightened out with the itty bitty brain of the PCM and it's not surprising that a few people have had to run a bit of fuel through to resolve.

My prescription for success has always been when changing tunes to start it off with a couple freeway onramp blasts. A trickfnck of the PCM if you will that leaves the PCM scratching it's head and pretty much speeding up the relearn process.

In my experience, I don't believe you can realize the full benefit of a specific tune until you have ran at minimum a half tank of fuel. Of course differences can be felt out of the gate, but it's time and miles that heals any hiccups.

 

I certainly appreciate you guys posting your experiences here, I'm ordering one and will be looking forward to the extra features as well.
Does anyone know if the "crawl" tune will be a feature that can be automatically activated when you shift the transfer case to 4-LO.
And do we have a timeline on the TPMS and 4-HI locker functions?

Many thanks

 

interesting idea on the automatic change to crawl when shifting into 4wd - i'd like to see that in a future update. this is the first i've heard of that - has superchips mentioned that as a future feature?

i've watched most of the threads on the superchips device and haven't seen a timeline. not having tpms or lockers it's hard for me to get excited about it, but i hope it's soon. i think a lot of people are waiting for that before purchasing. i would like as many people on this device so that superchips continues to make it a priority for updates.
