Any video proof of this working?

Video proof of the tune with 4.08 gears working with SRM?

I'm just playing devil's advocate here, but if you don't trust his statement that he has done it, are you really going to trust that the car in the video has 4.08 gears installed?

Well after a B A D experience with my preferred shop and this latest announcement by EcuTek I'm jumping ship from the shop and uprev. Heading over to M&S Performance on Long Island this Saturday, having the ART pipes installed and a Visconti tune, looking for 93 / 93 aggressive / 93 w/75 shot nitrous / valet. May do the flat foot shift and launch control, we'll see not really sure but I'm super excited. I'll be taking video's of the runs especially when we spray for the first time. I'll post up the results.

Buy a tune and I'll let you make a video to post up ;)

I will keep you in mind sir, def has my interest.

I don't have 4.08 gears and I already have a tune ;)

Joe did a drive tune for me and offered me some cheap dyno time in the future (2 years ago) but TBH I haven't had good communication with him - I even left him a voicemail recently reminding him I owed him money and wanted to pay and got no response lol

Do you happen to know the master tuner in Austin? I'm not even sure of his name, but I spoke to them a few months ago before the features were fully released (you had them but not many other tuners did). I am interested in the new features for sure, but really only for multiple maps at this time. While I prefer to keep my tune local, I am considering purchasing a cable and upgraded features (and possibly a look at my current tune with some data logging). I'd be happy for you to PM me your thoughts and possibly a quote for your services :tiphat:

Thanks, let me know if you have any questions

No I dont know who they are.. never heard of them

I'll send you a PM

I just like to have my ducks in a row, what are your cost for tuning and traveling cost to Florida?

Im interested if your traveling to FL.

Doesn't make sense to travel that kind of distance for only one car.. but if we got a group of cars together it would be worth it to everyone

What setups do you guys have now?

Curious... any new and exciting features for the 7AT?

For example, adjusting allowable minimum revs/road speed range in gear to cancel the automatic downshifts in manual mode (with an anti-stall feature, I suppose?) would be pretty awesome.

No, EcuTek isn't doing any TCM flashing at this time.. all that stuff is done via the TCM

I feel you. By the end of the year I'll have FI exhaust, stillen G3 intakes, FI LTH,FI oil cooler, CJ Motorsports billet oil pump gears and steel backing plate, and CJ Motorsports intake manifold (CJ motorsports parts pending on production).

John check your email please

Uprev doesn't have a fuel pump duty cycle...did I miss it that ecutek doesn't also? Could anyone guess what our pumps at with every bolt on besides heads and cams, you know the normal stuff.

You mean injector Duty %?

EcuTek has that!

No fuel pump, like the pic. Need to know what it can flow at 7800rpm at the moment.

The Nissan 370 doesn't have a fuel pump controller like the Subaru or like the GTR... so there's no duty to log or change.

The pump is ON or OFF.. that's done with a relay that's controlled by the ecu.

Even if you have a car with a pump controller like subaru or gtr, logging fuel pump duty isn't very useful using OEM hardware. It's really only used to make sure the fuel pump isn't overrunning the fuel pressure regulator at idle.

We found this out when we started wiring fuel pressure sensors to the ecu to monitor fuel pressure on bigger powered setups.. we found hardwire 485s was causing major fuel pressure creep at idle! I ended up making a plug and play hardwire kit that allow you to keep variable ecu control pump speed with all the advantages of going direct to battery power

On brush-less fuel pumps we can make the speed of the pump very variable using certain pump controllers + custom ecutek code.



John

Well that makes sense then! :tup:

Now do a need a bigger one :icon14:

I haven't done that test myself.

I know a full bolt-on car does tend to use all the of injector

Adding a DW300 fuel pump should bring the injector duty down a little..

Swapping the pump would be the best option for everyone.

On the Flex Fuel 370z I did, I kept the stock pump and installed GTR Injectors.. works pretty well

John

That's all I want to do. GTR injectors with the stock pump on E85. If I get 10hp and get some for $100-$200 you can't beat that power to dollar ratio!

Yes, but like I've explained in my other thread you won't see any power gains going from 93oct to ethanol on these cars.

Not a single hp.

If someone shows gains going from pump to ethanol they should probably spend more time on their pumpgas map.


Now 91octane is a different story, they're gains to be had !

John

I wonder if seasons play into it too. Like a 93 tune in January might not show same results as July. Like e85 I believe all gas changes throughout the year. Thats a way to show a gain between the two. This is one test I can't do a back to back on as I'll need the tank empty to fill with e85 while at home, swap injectors and flash there to comp for the bigger ones.

visconti or scott what model GTR injectors R35?

Any new model. They're 545-575cc?? Blue, drop in. I'm on a GTR forum and just asked today. I got like 7 replies at once. They're a dime a dozen in that world. Some with 1000 miles.

wow thats a cheap upgrade hey

r35

That's quite a bold statement. We regularly have even 2.0L 4 bangers pick up a whopping 5hp on E85, even being at MBT on pump gas. Does the "fuel is naturally oxygenated" mean anything to you?

have you had any 370z's?

Jon at Z1 has had quite a few in the 10hp range. Guess he needs to learn to tune :stirthepot:

that's what i hear is common too (7-10). like you said it would be a good $ to hp ratio, but if there isn't any hp to be made, it's a waste of money.

It resists detonation, and runs cooler. I wouldn't say a wast of money.

what do you mean by it resists detonation? and by going e85 the car runs cooler?

You want me to take a picture of me hugging my 2015 I just tuned on E85?

LOL clearly.

E85 burns much cooler, thus helping to keep Oil (And other) temps down. and due to that property, it also gives you the ability to play with the timing more without the risk of detonation.

So are the fuel lines rated for e85? i reading through this thread backwards, so i hope i didn't miss anything, but it looks like we are just swapping injectors. I am concerned long term breakdown of the fuel system.

e85 is something i have used before ( on different cars ) and would like to use on the Z if there is a benefit

thanks!

We run E85 on vehicles with fuel lines from the 1990's and they're fine, why would you be worried about the lines in the Z? It's not a boat... lol

[QUOTE=VitViper;3294131]You want me to take a picture of me hugging my 2015 I just tuned on E85?

Lol, well put sir.

Is there any development going on for the z33 ?

never knew that... i always thought e85 was a weaker than 87. learn something new every day :D

thanks for the crash course.
