Interesting way to prevent high speed driving...

Huh. I thought our cars had an antifreeze coolant cooler where the coolant from the engine is what cools the trans fluid. To add an additional trans cooler you tap into those lines.
#82
Not debating that, I just know that a previous member that probably knew the most of any about this car did a trans cooler and said that when he checked with the odbii scanner it showed an error code that didn't show up on the car that was due to tranny fluid pressure through the cooler. He did run his trans cooler for many miles without a problem but he also didn't seem to care about warranty so just make sure. If anything check the Lancer forums on the trans coolers they run because they use JATCO as well

ya the guy that told me about this told me to make sure u install a big trans cooler before turning it off because it will get hot. i already installed a huge cooler..its about a quarter of the size of the radiator lol..its rated at 29,000 btus..that should keep it cool :-)

There is a product I used on a right hand Japanese spec Skyline called the shadow e-drive. It cost like 10,000 yen ($100) but it skewed the ETC perfectly. I got a hold of my friend in Japan he told me they now have a newer model called the Shadow E-drive advance 2. The newer model is plug and play for newer vehicles with ETC. It won't give you a 100% throttle but it does increase the factory throttle signal by 15-30%. You have to order it with the harness for the VQ35DE.

By the way, just bought mine about 2 months ago, love this car!
#89
try resetting it while you're on the highway. when i do that the computer averages 30-33 mpg which probably isn't too far off from what you're getting

Researching this Throttle booster edrive and beginning to think it will do nothing.
The throttle control at the pedal will send a skewed signal to the PCM with this device. But it will only change the ramp up of the throttle opening.
I think the actual throttle governing is happening from the PCM not the throttle control unit at the pedal. The pedal assembly is just a simple scale of throttle opening. As we know the throttle governing that we want to get rid of happens at WOT so this device being plugged in between the pedal assembly and the car would be at WOT either way in turn the PCM is seeing WOT and adjusting accordingly.

I understand it isn't eliminating the cutout point but I'd rather have some throttle than just 40%. Manufactures are getting trickier these days with there programing hoodoo. I get limiting the general public but think they should give the option to buy a trim level up with a beefier trans-cooler and an aggressive program.

It is pretty sad we purchased a vehicle that only delivers the advertised horsepower some of the time. What is interesting is my '13 2.5 Altima did not have the same "pull back" sensation when under full throttle at high speed, I noticed it immediately on my Maxima.
#96
I will try this but with rush hour traffic daily and below 20 degrees almost daily it won't be for a while.
#97
I doubt it will work, I think the car looks at MPH when determining maximum throttle percentage. Just a guess.
#98
At this point I'm not certain at what the vehicle bases the cutback on. Usually the MAF, TPS, and O2 sensors are tied together in a loop. MPH is governed on the vehicle as well, but most say they are just accelerating when it cuts back.
Once I get back home from traveling I can try to set some time aside to datalog. Unless someone else finds out first.
