Also needs more discussion about BBKs for track use

It's a rare occasion for you. I gloss over so much, it's sad.

And then go to Facebook to ask the same question that has been answered dozens of times.

I logged my canyon and track drives and could tweak and edit tunes easily on romraider to make as many adjustments as I wanted until I had each tune running exactly how I wanted. I created a tune for canyons at elevation. Had another more conservative tune for track days. Another for 91 and for 93. I could switch freely between tunes depending on what fuel I was using and where I planned to drive. I also could tell based on my logs the effect of each part I added (Mishimoto inlet tube, 2017 header, various catless and catted headers) and how my tune was compensating and adjusting to those parts.

Not really sure how this all compare with Ecutek but I think $450 (or w/e it is now) for OFT is a bargain for everything that you’re getting (ots e85/91/93 stage 1 and 2 tunes, plus all the other tunes and maps available open source) plus the loading and logging and real time monitoring functionality.

Probably the only downside was the customer service was very slow at OFT but you don’t really need them for much.

I actually wish OFT would hurry up and release a product for the 2nd gens. Seeing how cheap e85 is right now compared to 91 is killing me lol.

But see, your reason is far different from most. You actually know what you're doing and do much of your own tuning. That's completely understandable because you only need the basic goodies for you to do exactly the same thing. So for you, agreed, OFT is the way to go. Just by the way, Ecutek does everything you mentioned if not more.

So are you REALLY trying to act like you don't understand why people would want to pick up a used OFT for $350 ($500 new) vs $1350 for an Ecutek tune and fuel kit?

I never had any issues with my BRZ running E85 on the OTS OFT tune. Watched the parameters and saw no need to datalog to try to get another 4-5 whp out of it. Started fine in the cold and pulled strong with no knock and good fuel trims.

But that's besides the point. I didn't have to go flex-fuel. If I just went straight E85 like OFT folks do, then I wouldn't need the additional kit, and we're only talking $750. But I guess it's just me when it comes to the peace of mind. I hate straight E85 tune because you're never actually getting E85 at the pump. So, even though your parameters are within margin, they can still be off a good little bit IMO. Just the thought of that would bother me on a daily basis. Having to watch trims every time I fill up, etc. I don't have to do any of that with Ecutek. I did early on, to get the idea, and that's that. I know that 100% of the time, no matter how much E85 or 93 I stick in my fuel tank, i'm getting a perfect adjustment in tune to accommodate my fuel.

The cool thing about OFT is it is great and simple way to get an improved tune. For DIY'ers it's also a lot of fun to play with. I spent a lot of time playing with the OTS tune and making changes to get my car running and make changes to it as I go. When I went flex fuel I had steve99 do a tune for my car buy I enjoyed playing around with it up until that point. It's not perfect but it does work pretty well.

As I responded to DarkSunrise above, I do agree with this logic for DIY'ers and can totally see the benefit of saving money if you know exactly what you're doing. I am no DIYer when it comes to tuning and definitely prefer someone who has been tuning for decades to give me the optimal tune.

I only skimmed the first 7 pages of this thread, but Blitz Japan has a nearly identical intake... lol.

I am trying to understand the $750 number. Cord, dongle and license (new) is $625. Where are you getting an ECUTek tune for $125?

Xero-Limit (used to go by Moto-East) does the full package for $800. I snagged it up during a sale, so that's how I got it down to $750.

That's a pretty good deal. But that is an off-the-shelf tune, right? And is that a single tune?

I understand with a FlexFuel Kit, you really have no need to switch tunes like you would using an OFT with no FlexFuel, but that gets back to needing to buy and install a FlexFuel kit in order to be able to live with a single tune.

And then you are still talking about a stock tune that is not optimized for your car (just like OFT). If you want to optimize using a dyno/tuner, I think you are talking an extra $750 - $1000, right?

Conversely, you had guys getting optimized tunes for OFT (obviously, not nearly as specialized as tuner/dyno tunes) for $50 - $100.

Don't get me wrong, I like options. And if I was going FI on a Gen 1 (or a Gen 2 or that matter), I could see spending the time/money for a very customized tune using ECUTek.

Mine (and others) only point is that it was hard to beat the bang-for-the-buck you got out of OFT on Gen1 and that any complaints about customer service (at least for those of us late, late adopters) falls on deaf ears because all we want expect is the hardware product/stock tunes. I was always intending to pay Steve or Wayno to optimize and given the wealth of information on this forum, I never expected to ever even correspond with Shiv (and I didn't).

I’m not sure how EVERYONE does it and I understand the pump states “up to 55-85%” which leaves a lot to argue. At least where I live (Wisconsin) I know firsthand that the blend does do 85% ethanol and finishes off with 15% unleaded. Give or take 1-3 gallons margin of error (over a total of 500+ gal)
