hey guys, we just completed the reflash for the 07 VQHR base model Z done.. (well.. 99% done with the code..)

Torque gains throughout the entire torque band..GOOD low to midrange torque (~approx 14 ft-lb gains at around 3500-5k rpm), fairly nice high end torque increase (~9 ft-lb at. 6k+), and redline is now at 8k for lead foots..

VERY consitent power increase throughout the entire RPM bands, overall peak power are approx 9-10 rwhp, with gains up to 11+ at 5500.

good stable AFRs throughout.

interesting throttle body control on the VQHRs... very different than the non HRs. should be very interesting for those in racing applications. on a test at freeway speeds. if you floor it, the car 'launched forward'. the retail version will be more tame and controllable, but for those that want the on/off feeling. we can now do it. heheh.

as a side note. if you have 93+ octane, Tadashi created a special map that actually gained 17+ rwhp due to advancement in timing, but thanks to our crappy gas in CA, would ping sometimes.. we saved the settings, so maybe with a little bit of refinement on that code. those that have better gas can have even more power.

all these numbers i am quoting are from the prototype on an 07VQHR Base model..., actual gains may vary from case to case. but these are very promising.

we need 2007+ G35Sedan STICK SHIFT models to begin prototyping. we already have a volunteer for an AUTO, so now we need a stick shift car.


your car will be down for two weeks as we send the ECU to japan to download the code, and then when we get the ECU back, we can begin the development. the volunteer will get a free ECU reflash along with another reflash for free at a later point. we need relatively stock cars for this development. i.e. stock intake. stock exhaust.. (intakes are ok. but preferrably bone stock)
for those interested, please PM or email me.

thanks

Long time no speak friend!

I'm back, but the Z is gone.

You still on AIM? IM me sometime, maybe we can work something out.

 

aim, yea whenver i can. or email is best.

Damn too bad, I have intake and exhaust-

 

Aw damn... Why didn't I get a MT model... LOL

 

does it void the warranty?
this is a long shot.
u guys have loaner car available?
lol 2 weeks is a long time.

 

Will this eliminate the 2-3 inches I have to press on the pedel before the car reacts? Thats what Im interested in!

 

I could do it. I have a 6-mt, and no other mods except H&R springs. I also have other vehicles to drive while it's down. I have approx. 17k miles on the G so far. I already did a baseline Dyno too.

 

Those are nice numbers for a stock 6MT. Hope they'll develop the ECU soon. I am very interested on buying this mod if it proves to be worthwhile. 17whp with the hardcore software is very nice indeed.

 

Sorry to thread hijack, but I have some questions.

What would be the estimated pricing on this mod? We do have 93 gas here in PA. If I got the 93 mod and got stuck with 91 somewhere would it hurt my engine or shift to limp mode, or could it shift to a map for 91?

Also, if I got the dealer to do the ITB 28 and/or 45 reflash (which I had planned to do), would this simply overwrite those edits completely? It sounds like your code is based on the Rev A version; do you plan to do it based on the Rev B or C?

I'm pretty ignorant about this, as you can probably tell.

 

Oooh... this should be fun.

My guess is that it will be in the same range as the previous re-flashes... probably $500 and a 2-3 day downtime as the ECU is shipped back and forth.

 

Will this also eliminate the speed governor?

 

i'm not allowed to specify any pricing info right now.

it will:
raise rev limit,
remove speed limit
adjust timing
adjust AFR
adjust throttle response
adjust misc code here n there to allow for better driveability


we always try to work on the latest codes, however, we do not recommend you going into the dealer to reflash over an ecu that has already been reflashed by Technosquare..

if you have specifically asked for a higher-octane tune, that ecu will be reflashed to match customer requirements. However if you are unable to meet your own specified requirements for octane level, to a certain degree, the ECU will still have the ability to run on lower octane or poor gas, granted you don't induce a severe load (i.e. FLoor it up a hill, with 4 fat friends in the back seat). I would even suggest you carry a bottle of octane boost or find 5 gallons of 100+ race gas for mixing to prevent pinging in the event you find yourself out of state with mom-n-pop 91 gas station..

the "2-3inches" comment, yes. this the throttle response change from factory specs is basically allowing the TB to open faster/sooner. however, unskilled drivers will have a tendency to hit the rev limit before physical shifting. yes. we can make it almost instantaneous switch open. there is research underway for that 'sweet' spot..

 

As part of raising the rev limit, hopefully a bombproof rev limiter remains? i.e. if you raise it to 8k, it's a solid limit and the RPMs will bounce off the limiter as it does now?

 

Wish I lived in CA 'cause I'm your stock 6MT. Can't see how I could do it across the continent. Oh well. I can dream on.
