Chiptune prius

possibly, but at what cost to mpg's, can they tell you?

 

why wouldn't toyota factory install it?

 

but the lexus is smaller and doesn't get 49mpg.

 

here's a thought, have them install it, and tell them if it works, you'll pay for it. make sure you have your phone ready to capture their facial expression.

 

my money says it doesn't work.

 

I am not sure you can do much to a CVT engine (can see what the Honda guys try to do to their CVT Civics since Civics have a huge aftermarket for performance upgrades. Even the HX's have little performance mods for it besides the good old I/H/E). I did look at the air intake and it may be better for the engine if you route it toward the bottom or buy a cold air intake if they sell one. Usually people change the exhaust, headers, and intake to get about 10-20 hp increase. At least this is a physical change to the configuration but a chip....maybe for this car...Honda S2000 is a different story (2006-2007). You will probably gain more by changing the seats to lighter seats and gutting as much as you can without compromising safety. Changing to lighter wheels, install sway bars, maybe upgrade the suspension to coilovers. That might be a better $1000 to spend.

The US Ct200 and Prius have the exact 0-60 that's why I didnt buy the Lexus. It feels sportier and more premium but they are both as fast. So, I don't see how you can chip it to be faster. The Lexus 400H hybrid is faster than the 350 even though it's a hybrid. If Lexus could make the US CT200 faster by programming alone, they probably would have done it. With them both accelerating the same, I chose the cheaper car instead. Although if the cargo was the same, I wouldve bought the CT.

 

Chip/ software remapping , force induction is nearly impossible for hybrid without really messing something up! Jetta hybrid 0-60 7-8 sec. Turbo charged, with GLI tune suspension, 7 speed dual clutch transmission that completely disengages then rolling down a long hill at hwy speed. Around 42-46 hwy mpg

 

There is another tuner from EU that claims they can tune up Prius:
Tuning Datenbank – CHIPFACTORY

From 100 PS to 117 PS
From 142 Nm to 160 Nm

There is a easy way to test any performance gain you just need cheap OBDII adapter and a phone, transaxle has build in torque sensor and you can always check it real time under driving conditions.

 

Freedom to modify your vehicle in any safe way you wish.
But whenever I read about anyone wanting to do any modification to a Prius to change it from a power/acceleration standpoint my first feeling is to ask why did you buy a Prius?

In my opinion, you're buying HSD. Hybrid Synergy Drive, and it's priority is fuel efficiency and emissions standards. If you purchase it, and then want to try to change the nature of the beast?

Well you can try to change the spots...but that isn't the cat you bought.

 

Like I said, Freedom to modify any way you want...BUT..
I find it interesting that with further revelation this isn't even a vehicle you chose to purchase for yourself.
Which kind of backs up my premise.
Most (Not All) but most Prius purchasers and owners, buy and operate them because of their efficiency, not to obtain more speed or power.
Also I would argue, that it's very difficult to increase power without affecting efficiency. There is no magic that allows for more power without cost, and that cost is usually on the fuel efficiency side.

Go ahead if you wish and tune it any way you want. But I would say my opinion is for most Prius owners, they would rather have 2 mpg, better efficiency than lose 2 mpg for any performance gain.
I never said it was stupid to try to modify your Prius.

But I did say I always wonder why someone wanting to change the Prius into something faster or more powerful ever bought a Prius in the first place.
Since you now admit this was a Birthday Gift, I guess the answer is...you never did buy a Prius in the first place.

And with all the "Lexus" badging you are attaching to a Prius?
I do have to wonder if you didn't get the wrong Birthday Present.

PS.
I don't mean to sound snarky....you really do have the freedom to "play with" your Prius any way you wish.
And I will admit for me personally?
Well....efficiency is a much higher priority to me, than power or speed. If you could care less about a 2mpg loss....I would say I could care less about a 2 horsepower gain.
I'm suspecting this might have a lot to do with a demographic age gap.

 

Good Luck with your Prius.-Kid.

 

Prius has very nice power train. That's pretty close to electric propulsion what goes to how it feels - that's extremely cool. So I could imagine why non-green people could want it too.
Another aspect is that the increased output does not _have_to_ affect every day performance, even it usually does. I'd like to have more power in power mode even with increased fuel consumption, and could even drop some power in eco mode (assuming it saves something) - by default neither is possible.
And third chip tune option would be to optimise for certain fuel, e.g. different octane ratings, RE85 or CNG (this requires some extra modifications). That could be ecological thing to do..
