I know it is being stated that this unit is a reflash, and I know it's from Mines so it's going to be expensive. But to me the unit sounds like a tunable ECU much like Hondata (Which is $1,000). I could see the price being justified if that's the case.

yes this is better than any dyno tune out there right now because mines has taken the time to figure out the vvel.

go here for the right page What's New? so whats included:
Specifications are as follows.

・The speed limiter has been removed.
・The rev limit has been changed.
・The injection and ignition map has been changed
to increase the response and fuel economy.

So yeah expensive as hell for 3 hp but id like un speed limit and rev limit to 8000rpm!

HIGHLY doubtful it will reach 185. MAYBE it might get to 170-175. My stock Trans Am put a LOT more power and torque down, weighed a hair over 3500 and was pretty aerodynamic for a muscle car. It'd get to about 180 before drag stopped it from pulling. We're talking at least 40HP and 90Lbs of torque more than the stock 370. Once the car got better gears and stuff, I was putting down about 15% more torque. Still limited to about 183. If I'd gotten the long-tubes, full exhaust, better intake and a tune, I may have gotten it to 190.

your car also had a V8 which makes it easier to reach higher speeds ;)

the current 911 base model carrera reaches 180mph with 345hp.
so with a less restrictive exhaust on the 370z it should be able to reach that speed. not to mention it has more aggressive gearing and a higher redline with the mines VX ROM. i doubt it will be 3hp. it will most likely be a 10-20hp peak gain with much larger gains throughout the power band.

^^^ My point exactly... With headers, better intake, and a good tune, the Z should be able to reach 180.

BTW, my car had 3.73's. The motor didn't work as hard to get me to higher speeds, but I have to admit, around 150MPH I was doing 4000RPM! Not much more room since it red-lined at 6400. I assume I was doing about 5800 when I hit 180... Couldn't tell EXACTLY how fast I was going since my speedo only went to 155.

now do you have a 300zx twin turbo?
it's much easier to reach those speeds with bolt on's on a turbo Z hhehe.

400whp is still accessible from our little T25/T2 hybrid turbos haha.
im hoping for 450whp from my stockers, im also going to be running the stock compression from the NA (10.5:1) ;):driving:

I didn't see this mentioned in the thread yet, but remember, in Japan the standard octane in gas is much higher than even the most premium North American gas.

This was discussed on a GTR forum, namely the JDM R32-R34 GTR's that were being brought over to Canada and the US in droves. JDM ECU tunes will be operating on the basis that you're running Japanese fuel, not North American fuel. You'd have to re-tune the tune to adjust for the Octane deficiency!

JDM Tunes are not only dangerous to use on USDM-bound but Japanese-made vehicles, but they are entirely ridiculous given the access to reasonably priced ECU tunes on our shores.

My advice, take it or not, is that a Mine's or any other companies ECU tune, be it piggyback or reflash will eventually ruin your car, even if you're running 94 octane. Seriously look into ROM Octane conversion charts before buying a JDM Ecu Tune!!!

No. My 90 Z is NA. I bought it when turbos were too expensive for me. I was later going to put in a JDM turbo motor. ($1600 with trans)

But then I saw the 370z and decided to hold off.

lol, this engine is very complicated? Coming from Direct injection, tuning this thing will be cake.

Are they nuts?!

UPREV $400 (I think or a hair more). They already have a 370z ECU and will probably release it in the next few weeks.

I just did the conversion, 184,800 yen = $2,015.50

This is nuts. way overpriced.

dude swap, then get an interior from tunerD, then get a full exhaust from Specialtyz, doolz intake from ash, upgraded intercoolers, MSP manifolds and GT2860'rs the same turbos that the R34 N1 has, and some wheels and suspension and you'll be happy as a lark.;)

and much faster than a 370Z, look better, older people will respect your Z because they know it's fast. and your resale value if you keep it in good condition will be about 15k or more for years to come with all those mods.

which is more than i can say for older 350z's, or when the 370z gets a few years older.

Actually, my goal is to buy a 370z as my daily and convert my 300z to an electric car. It'd still be faster than it is (A LOT FASTER), and it's a great platform to do electric car conversions on. I wish it wasn't so heavy, but I'll end up doing some weight reduction on it.

Honestly, I want a new car, and now that I can afford it (I couldn't afford a new car when I bought my 300z) I can afford to keep both, and have 1 totally reliable daily driver and a project car too. :) Pretty much how I'd always want it.

Is it work with 370z nismo? How it's works? Is speed limit cancel?
