Just wondering. I'm not the best with ecu flashing understanding. Do you know what effect on mpg this has??

 

Yeah, if you have a heavy foot then your MPG will go down. If you have a light one then it will probably go up a little bit. Thats the simplest answer that can be given.

 

My 2007 really seems to hang onto revs way too long when you let off the gas, is that something that can be gotten rid of? And is this just for emissions or what? I've actually seen the tach jump slightly *up* when letting off the gas quickly.

 

I've got an '08 G35 6MT sedan, but I'm not sure if I will have 2 weeks I can be w/o my ECU.

I sent an email here yesterday: 'contact@technosquareinc.com'

I also have a 'before' dyno with A/F bone stock.

 

So am I to understand that new ECU flashes aren't available yet? I'm in Canada so I don't know whether it is available to me. The only thing I would want changed is the electronic top speed limiter. Is there a simple flash for that? Don't really understand the process either, but it seems similar to flashing a BIOS on the computer in principle.

 

waiting for the 2007 6mt enthusiast!!

 

still awaiting the test mule 07+ g35 sedan 5at ! cant wait!

 

I have a 2007 VQ35HR Auto. Once I make one more visit to the dealer in a week or so let me know what you need me to do pm me.

 

Hi, I am a french 350Z owner and I would like to know if the ECU reflash can work for my european car.

I think I will add a HFC converters (AAM or Berk), an Injen catback and a Injen intake (as soon as available). We have 95 octane gas here (and 98 octane in France).

Is it possible to use a cipher programmer to install the reflash by myself ?

 

Update:

2008 G37Coupe S 6MT ecu is sent out to Japan, will be back soon,

for Overseas owners, yes, the ECU should work for your European car, if we dont have the program, we may ask you to send your ecu to us so we can download the program (such as we are doing for the 07 prototypers). Cipher is a different company's product, and is not supported by Technosquare.

the Enthusiast ECU was sent back to its owner, and the code is being finalized,

we should have something worthy of posting within the next two weeks.

thank you for your patience.

the Reflash is the reprogramming of the factory program by over-writing on the flash memory thats onboard the computer. similar to updating a firmware for a hardware unit.

 

So is there a way to do this, keeping things the way they are now, but just removing the speed limit? How much does something like this cost? How would someone like me in Canada do this? Is there a simple explanation of the process? Something I remove and send to you and then reinstall when you send it back?
Sorry for the novice questions.

 

I cannot speak for technosquare directly, but yes, that is something they should be able to do and you would have to mail your ECU to them to get it done as there isn't any easy way to do it yourself. The process to remove the ECU it pretty simple. The first time I did mine it took me about 30 minutes. I could pull it out a lot faster now. There are write-ups on how to do it. Just search for it. It might take some time to find it, but probably not as long as it would take someone to type up a new one.

 

Is a reflash tailored to the mods you have or are planning to do, or is this a stand alone upgrade? For example, I am stock now and eventually might bolt up some mods: can I reflash while stock or is it advisable to wait until after you complete the mods?

 

Good question, if your not stock and want the reflash to be tailored to the mods you have what do you guys need from us to do an effective reflash? Just a mods list or a dyno graph with A/F?

 

You choose the reflash program based on the modifications you have to your car at that point.

most important for an effective reflash would be your modification list that has to deal with Air and Fuel, (i.e. we dont care if you have an LSD or strutbar or coilovers. we care if u have HFC or plenum)

best is an AF measured Dyno from behind the cats, a tail pipe sniffer would suffice as well.

adding or changing your engines modification after you get an ECU reflash may require another reprogramming, but in most cases not really.

the two mods that change AFR the most on the VQ Zs are HFCs and plenum spacers/total plenum swaps. everything else (test pipes, intakes, echaust, etc) will change it slightly but not as much/bad as those two.

reflash optimizes your mods.. there's alot of good threads on this subject. feel free to search in the engine / mod forum for "ECU reflash". or goto www.technosquareinc.com and read about the Z ones here:

Cheston, just a minor clarification...should test pipes be in the category of items that change AFR the most?

 

Remove the speed limiter? I assume your FI or planning it lol, our cars dont make it to 160 that fast, and not much more than that I would assume.

 

Any idea when the 2007 reflashes will be ready?

 

It would be nice to dyno in 5th though 1:1 w/o the limiter becoming an issue.

 

There is vid of some stock Z's hitting 172 on youtube, at least that is what the digital speedometer is showing. Sure they have the ECU done.
