Will do!

Going STG1 EcuTek or COBB is the way to go *cough* *cough* EcuTek ;)

I think he is!

No I dont see any benefit in that mostly because the car doesn't make anymore power with leaner air fuels on a hot or cold day. Even if you were able to squeeze a few more hp by leaning the car out it wouldn't be worth the risk of riding closer to the threshold of knock for 2-3whp

Let first off by say John has been great the whole time and a pleasure to work with!!
OK on to the review so far :)

Ok guys , Been a week of driving on my ECUtek Vs UPREV and can say that it “feels” about the same, The ECUtek shifting is still something that’s lacking IMO, it will only shift firmly at WOT and high RPM’s ( An I still feel UPREV shifted better) . An having a 7 spd auto and the stock shifting logic is terrible it was something I REALLY like on my UPREV. Pretty much anything past 1/3 throttle UPREV would shift firm, and being I drive exclusively in manual mode this is important to me, and the LAZY shift is not for me. The throttle responsiveness is close but still feel UPREV has a bit of an edge here also. I finally got a 1-3 WOT pull in this morning and 1-2 felt about the same as UPREV but hitting 3rd it felt like a flat spot ? Car didn’t pull hard right away,( The shift was EH) but the RPM’s did rise up again fast kinda took a second just felt slower. I was told the tune was just about spot on 99% . John said to make it more aggressive wouldn’t do that much and the tune is safe so that’s fine with me as I want a safe tune only.

I have one more flash to load but haven’t had time. Been busy with the wife( Wedding anniversary this week, MRI for my back today) so lot of things going on. I will load this up before the dyno tomorrow just so we have an apples to apples compare. I will be surprised if I make any more power tomorrow when on dyno but we’ll see. Depending on what the numbers are I’ll might sell the Ecutek but not sure. The gain if any has to justify to me to have spent $300 extra dollars for Ecutek. An the fact that I have a auto and AWD the racerom features and updates are of no use to me. Was looking to strictly make more power and enhance the cars drivability. Maybe I am expecting too much and there really is zero difference in them I don’t know, but going into the dyno tomorrow I’m not feeling too good about the $$ I spent.

Thanks for the review.

It sounds like there is a lot of room to tweak yet. Keep us posted! Thanks for the review so far.

BTW, I have a 7AT so I am very interested in how that gets worked out.

i think the stuff you're looking for you already had since you're awd. i would want someone to test this out on a manual 370z.

The only difference in the manual would be the flat foot shifting and launch control, Theres no really power difference, Ran manual cars before :)

Next update will be about 930am tomorrow ! :)

i think the launch control could be worth it alone in the switch :D

in for the update tomorrow

Launch control is awesome I had it on my Stage 2 STI via Cobb. It's perfect for 1/4 mile track runs. Also Flat foot shifting was cool too. I miss my STI.

My 12xs coupe with no tune and Stillen Gen3 intake I got consistant 13.7's last Nov with traps just over 101mph. I'm anxious to take it this year now that I'm tuned but from reading this thread I may sell ECUTek and go Uprev then go to track.

Agree with you guys for the flat foot shifting and the launch control is a reason to switch just one its own. I'm at the Dyno now cars being strapped in :)

...... We'll see!

Results are !' ..,,

ECUTEK 302 WHP and 240 WTRQ. I made more WHP 15 and 9 more WTRQ. I guess John and ECUTEK WIN!! THamx John this week aha been AWSOME ! Numbers prove it guys ;)
Thanks for following

Graphs will be up when I get home

Very nice. In your case at least, there appears to be a measurable and not-insignificant gain with EcuTek versus UpRev.

I'm glad you're happy. And thank you for doing this comparison. I'm looking forward to seeing the dyno charts.

I want flat foot shifts and launch control lol

I need this.

That's awesome. Avery370Z made 13 whp/10wtrq over the Uprev tune. Your gains are very similar to his.

OK guys finally got home and have a few minutes before we start working. The sheet will show that not only did I gain an overall 15+WHP and 9 WTRQ but I made it all sooner and throughout the entire band ;O. I was shocked to that. I thought I would just see it all up to from 2500-7500! The gains across the board and I am SUPER happy. Thank again John.

Nice gains. :tup:

Did they get a chance to look into the AT7 issues with the EcuTek tune you didn't have with the UpRev?

v7

You mean the 7spd auto shifting firmness, Yes John addressed it, It's good now

Very nice! this has helped move me towards ecutek rather than uprev, not to keen on tuning, but we only have one shop that does ecutek here, mainly on Subaru and Mazda and the GTR. They claim they do other tunes of vehicles not listed and exutek points me to them on the locator"

are these ecutek tunes just tunes run from the same map per say? or running custom tunes? or what i also assume can be both...just want to get a better idea of what im up against here.

this is there website FNP Tuned | Forced Induction Experts

shot them a email with a couple questions.

No you can have multiple maps , I have 4, there are all slightly deferent. I'm running the most aggressive map now. But is still super safe, We agreed to have the safest map that will make the most power. No need to tune the car to an inch of its life. LOL

So are you running standard maps? or a custom map as well? I assume the standard maps can be tweaked to run in certain climates or elevation. Just trying to get a better understanding. I know there are multiple maps, sorry I didnt make it clear. thanks

ANMVQ, that is great!

Just a quick question? I am about to trade in my car to either a 2013 G37x sedan with premium package vs 2013 G37xS sedan with navi package ( I believe the Navi package must have Premium package to get one)

The xS sedan advantage for me is the Navi , paddle shifter and sports seats, dont care too much on 18" duckfeet rims. Will the Xs heavier rhan the regular X? Price difference between the 2 is $3,500.

I might pick one up this coming Thursday.

Do you have AFR vs rpm available to post?

It's all custom mapping..

There is no standard mapping.

Over several months I've come up with my own "OFF THE SHELF" maps...they are written from scratch, I dont use anything EcuTek provides..NOTHING.

The N/A tunes aren't very complicated..

I send all my customers 4 different maps, Low --> High Octane.

Worst Cali Gas --> Best 93 Oct

I have you send me a log on Map 1 or 2 which are the lower octane maps and I review for knock correction , fueling adjustments and a few other things ;)

I normally ask you to stay on the less aggressive maps until fueling is sorted.

Once fueling is where I want it we can start logging on the more aggressive maps. The tune is adjusted until I find a happy place for the car.

All can be remotely.

John

Hey man !! :) No the XS IS not heavier , well maybe a little cause the base X has 17's but nothing not worth buying it, heck I made mine a X(S) lol I added paddles my winters and stock RWD sedan sport wheels , just no sport seats :/. But if you can get a Xs get it . We had an 08 G35 XS and I loved it :p

Now this would be worth it for a tune.

Thanks for clarifying! :tup: im not quite ready to get tuned, but I may end up contacting you when im ready. Thanks! :tiphat:

AMNVQ, thanks for the input.

I might sell my Uprev Tuner also and go ECUTek. So yours is all Etunes? How much did you spend for everything? I am planning a not so aggresive performance MAP.

I can save money if I stay with Uprev since I can tune this car on my own. First thing to do is to find a decently price G37Xs.

Does your ECUtek throttle a lot better now?

I wonder if Uprev or ECUtek supports a 2013 G's?

That is a decent run for a stock car. DS mode?

Ecutek supports 2008+ G37s

The 2008 which has only a 1MB flash doesn't have all the latest advanced features

Thanks for checking that! I might be getting either the 2018 G37xS or the G37X sedan soon!

I only want the G37xS for the seat. I find the G37x seat hurting my back. Does the Xs seat stiffer or just the same only wrap around? The paddle shifter that I test drove before seems lagging. I might save money for just getting the G37x and buy a lighter wheels, then Ecutek.

So how is the throttle response on the ECutek now?

The throttle response is very good !! He did a great job with that also . The XS seats if a remember right and lumbar support , something I thjnk I'm goig to need soon. ( back MRI on this past Friday) . But those seats have a seperate set of buttons for adjust for lumbar support. The seat sides hugging you are nice also :) .

Did you get the line pressure fixed?

Yes I did , got it all straitened out ! Thanx man

Time to update that signature!

All set ;)

WOW guess john knows his stuff for tuning..
guess it might be the route to go to see if can squeeze some more out of mine..
