Quick Question between OFT and Ecutek
 

Hello Guys, I'm kinda new to the forums so there might be a threat on this already im not sure. I'm currently running OFT Stage 2+ E85 and Sometimes Gas and I was wondering if its worth going with Ecutek and getting a custom tune from CSG with Zach Tucker(I know he's known for doing an amazing job). Goal is just to have car feel more lively like it should of from stock but at the same time keep it as reliable as possible. I'm not sure how reliable the OFT OTS tunes in comparison to a custom tune as well. Just curious on your guys take if its worth the money going custom tune instead of OFT. Thank you so much for your time. Appreciate it!

Why not get a custom tune for the openflash tablet? To be honest, you won't area whole lot of difference if you're staying naturally aspirated so I'd stick with Openflash

you really need a flex sensor kit compatible with OFT amd then also openflash becomes a very good alternative staying NA

On a 2015 car you can do flex on oft or even with tactrix. Ecutek is good but will cost you a lot more

How are you going to get an etune from Zach? The CSG website? I might do this since tuner im going to seems to be ripping me off.

Thanks for all your responses and Yes I have thought about going with OFT flex fuel kit. Although im not sure if they offer OTS tunes for flex fuel kits anymore. Also I've been told and seen that if i try to get a etune through OFT the process isnt the best as they take forever according to people(not sure how accurate that is though). Thats what leaned me going with CSG with Zach as I only hear good things and mayb i can take my car to their in house dyno if possible. So you guys don't think theres a big difference between OFT and Custom tune form CSG in terms of performance and reliability?

I think you're missing something. You can get custom tunes on the openflash tablet from someone in person or on the dyno

The difference between an OFT canned tune (that you can download from their website for free) and a Custom Ecutek tune is not too far apart performance and reliability wise. Obviously the "Custom tune" will be a little more nicely tailored to your car and eke out some more performance. OFT canned tune tunes tend to be a little more conservative because they have to be safe across a lot of different conditions and configurations. Roughly speaking, you could say an OFT canned tune can net you 90-95% of maximum potential, while Ecutek "custom tune" might more reliably offer closer to 94-95% potential.


Note, there is a major difference between what you might call a "Custom tune" and a "dyno tune."

• "Custom tune" - I usually refer to these as customized remote tunes. The tuner will work with you digitally over a few sessions to hone the tune a little bit, but it is not nearly as expansive as a dyno tune. As mentioned above, these can get you maybe 95% of max horsepower.
• "Dyno tune" - This is where you actually show up to a shop, get on a dyno, and really dial in a tune. These tend to cost 2-3x as much as a "custom tune" because of the labor and time commitment. This is where you shoot for the last 5% and possibly reach max horsepower for how your car is set-up.

That isn't to say that you couldn't also find a shop that will work with you to, say, make a "custom tune" using the OFT platform.



However, by that point, you're paying for the OFT unit and a new tune. Then the price competitiveness of OFT is reduced because the value factor of open-source tunes is taken away. This is especially true if you decide you want to go Flex Fuel (not to be confused with an e85 map) : I am not aware of any free Flex Fuel OFT tunes. Then there's the consideration of finding people/shops that will work with the tuning platform of your choosing.
