Anyone working on tuning??

[ChinoCharles]

Don't get offended by what I'm about to say if you disagree.

Saying there isn't any power potential in the 1NZ is bullshit. We have established this already. Someone is running around putting 180 to the ground in a Yaris on stock internals. Nobody will know how much the Yaris will or won't handle until ZPI's car blows up. PERIOD.

In the meantime, Ashley hit the nail on the head. If you want to see power our of your N/A Yaris (re: if you can't afford a turbo) you're going to want to start bolting on some less restrictive parts, then go out and give your car a good tune w/ a piggyback. From the graphs I'm looking at, 15-20% looks to be conservative. I think 115-120 on the ground from a Yaris with a relatively small investment is feasible, and a 20-25% increase in horsepower over stock isn't going to cut your engine life in half.

The power potential in this car lies in the restrictive intake/exhaust hardware and the gas-mileage-only stock tune.

I understand what you are saying, but the return on your investment just isn't there with this car.

If you want a fast hatch buy a MS3, a $1000 piggyback yields 70whp on an otherwise stock car, that's a nice return.

You'll never get that kind of power out of the Yaris for the same money even considering the higher MSRP.

(No doubt a 180whp Yaris is probably a blast to drive though)

anyone stop to think how the B16 gets 160hp? RPM's. rev that 1nz to 8500rpm and you'll make more power without doing a single mod, because power is just a function of torque and rpm.

(i am in no way suggesting that you should try 8500rpm on stock engine'd yaris, just putting the "power" thing in perspective)

also, remember the 1nz has an offset crank, very thin rods, and soft valve springs. all of these things lead up to catastrophic engine failure at high rpm's.

so, the money spent (wasted) to build a high-rpm NA 1nzfe should be better used either swapping or going forced induction. or hell, nitrous.

so, has anyone come up with an answer to the OP's question yet?

does anyone have a chip tuner or programmer out there yet? i'd invest 300 in a programmer well before i ported heads, turbo'd, 'charged, or any other power adder simply for the fact that i wanna run premium, and i wanna stay NA. so, tuning gets 25% for most cars, and 125 is a good amount of power for the size, weight, and stock brakes size of the car.

any way...back to the OP's topic and not wishful thinking or bickering about who's dong is bigger or what's gonna happen if you do a tune/program...i wanna know if there's a programmer out or coming out.
