Car: 2009 G37xS Sedan 7AT
Mods: Ark grip catback exhaust, Fast Intentions RHFC's, R2C SRI

Uprev tune: My first impression of the Uprev tune was that it a nice improvement over stock. I had my tune done immediately after installing my RHFC's and felt the difference in power immediately, especially in the mid-range. There was also noticeably less throttle lag. The Uprev tune came with 3 different maps. Tune, valet, and security. You have the ability to switch maps on the fly but be careful, there were a couple instances where I couldnt switch out of the valet map with out pulling over and restarting the car. During everyday driving the transmission felt noticeably harsher. In stop and go traffic traffic the downshifts were harsher and the car sometimes seemingly had a hard time choosing what gear to be in. Lastly there's there's A/F ratio and HP/Torque gains which will be shown in dyno sheets later.

EcuTek Tune: My first impression of the EcuTek tune was holy crap. During the first test drive I was in shock of how much more alive the car felt. The throttle response was great and the shifts with the paddles happen almost instantly. Huge improvement over Uprev in those departments. Like the uprev tune, you feel really feel the power in the mid range but it pulls right through the upper band too. During everyday driving the EcuTek tune feels just like stock. The shifts in stop and go traffic are smooth and I didnt experience and jerky downshifts like I did with the Uprev tune. The EcuTek tune only came with one map so I wont have that added piece of mind should I ever valet the car. New updates are expected in the next month or so hopefully something is in the works.

Now for the Dyno Results
All these pulls we're made on the same mustang dyno, on the same day.

EcuTek Vs Stock Vs UpRev


UpRev Pulls


EcuTek Pulls (The Tune currently on my car)


Hopes this helps anyone who was wondering about the benefits of one tune vs the other. I am by no means an expert this is just my personal, first hand unbiased experience with each of these tunes. The car simply drives better and is more responsive with the EcuTek tune.

 

Thank you so much for sharing this with the community! It's great to finally have actual data rather than comments based strictly off of presumption of what one software or the other might do. This is great to help people without an agenda or rooting interest one way or another make an intelligent FACT based decision. You are in the Hall of Myg37.com Heroes.

Please keep us updated.

 

Thank you OP!!! I have been debating between the 2 for the longest. "...downshifts were harsher and the car sometimes seemingly had a hard time choosing what gear to be in."...That would drive me crazy! Please keep us posted with the ecutek updates.

 

Did the same tuner do both tunes for you?

 

Right on! Thank you!

So im going in for a gear swap/quaife differential installation this coming week, going to be fully tuned afterwards with UpRev, this really has me thinking about my decision to use UpRev again. The fact you say you really felt an improvement in shiffting and throttle response has me very curious. I may just inquire with my shop about EcuTek... Thank you for sharing!

 

No Sam, that was the only other variable in this equation. When I got the uprev tune I had no intentions of getting EcuTek. The opportunity presented itself so I went for it. The same tuner would have been ideal for comparisons sake. To be fair I omitted the initial dyno sheet from the uprev tune bc it was on another dyno about a month ago.

 

If the weather permits, I'll shoot a quick video demonstrating the acceleration and shifting with the UpRev tune.

 

Ecu tek is made for real racing.
Ecu tek in UK is huge, & I can see why.

 

WOW! Thanks for the great post, you now have me reconsidering my Uprev choice for a tune in a week or two. You gave me some much needed info to make an unbiased decision.

 

I can't find any in Florida

 

The shop i work take my car to in Scottsdale (Dyno Comp) all the time already works with EcuTek on the EVO's they work on. Going to have a chat with them this coming week on their thoughts / experience..See if they have thrown this on any Z's or G's already.

 

HP-Logic in West Palm Beach for Uprev..... Dynamic Turbo in S. Miami for EcuTek

 

Do they offer e-tunes?(ecu-tek) assuming there are no tuners local? I am more concerned about improving throttle response and Shifting crisply with maybe a minor breather mod.

 

Thanks for the great info Jay, awesome resource for those getting ready for a tune, pretty dramatic difference between the two. Hoping to get this done later in the year so this thread is bookmarked!
