Just leave early. Drive it while the sun is up and the weather is good.

Are you saying that the OFT only comes preloaded with 91 or E85 maps? No 93?

The gasoline maps are intended for 91 to 93oct. There is no need to have different maps for 91 and 93 because that is the function of the Subaru knock controls system. Most of the mapping we do here is on 93oct. But once I'm done with that, I transition over to 91 and confirm that it's not too aggressive.

Awesome. So it sounds like we will benefit from using 93 octane gas with the 91 map.

Thank you for the explanation!

It's because when I was in 2.0TFSI tuning scene, there was a bit of power difference between 91 and 93 octane tune. Anyways, I'm all good now, just need to find a header for the stage 2 tune..

With your 2.0T, the extra 2 octane points definitely help because the engine is turbocharged. So each additional deg of advance you can get in there can be work as much as 10hp. In the case of the FA20, unfortunately, that does not hold true

Yes indeed. Running 93oct will ensure less knock correction and a very stable advance multiplier.

No wonder running 100oct tune felt awesome haha

Updated second post with e85 mpg. Lower than expected, but I was driving like a hooligan thanks to my car's balls finally dropping.

Weather has cleared up and I went out to burn off my quarter tank of 93. First time running the stage 1 and it was fantastic. Love when the change over happens, for me it got rid of a huge section of my torque dip!

Come on E85

16 mpg is pretty hard to swallow. E85 is more expensive in your area than 91?!
How is mileage with tune on 91?.... Going back to read again in case you stated.

You can always try it... Free with the OFT.

I'll post more mileage updates coming up. This week I should be driving a little more "economically" and I should have some 91 oct. mpg testing coming up as well. I wouldn't imagine it'd be worse/much worse than stock though, my tank lasted a *while* on the 91 oct tune.

Since this is a review thread I thought I would add my review in here. Moderators or OP, if you want my review out of this thread just let me know and I can start my own, I assumed the moderators would just merge threads if I started my own. It's also in my build thread…

I recently ordered the OFT. I ordered it on 2/17 and received it on 2/22 so shipping was relatively quick.

When I first received it I tried to interface it to my laptop. It indicated with map manager software that I needed to interface to car. So I stopped playing with it at that point on the laptop and then went outside to interface to vehicle. Interfacing with vehicle worked through the read phase and save phase, but then for some reason the write icon was grayed out and it would not initiate the write phase of the synch process. At that point I emailed Vishnu about how it would not begin write synch portion of process. That was last night at about 9PM cst. After emailing Vishnu, I tried to interface it with map manager on the laptop again since the read and save portion of synch worked. This time, it interfaced with laptop fine. I looked at the map list screen on map manager and it only had my OEM tune saved on it. So my assumption is possibly my OFT was sent with no tunes loaded on it?? I tried again prior to interfacing with laptop. When I did and was messing with car I noticed checking CELs I had a P0700. I never have had a CEL fire on my car. Not sure what that one is for. I cleared it at that point when checking… After giving up on the write process last night, at that point I downloaded the v1.42 maps (didn't want to mess with the 1.5x beta maps yet since they are labeled as "beta). I unzipped the maps. I loaded the maps into map manager and uploaded to the OFT. This list of maps was the appropriate list for my ROM type (I assume that is mandatory or it won't synch to your car, but I didn't try to synch maps for a different ROM type). At that point I assumed the write problem during synch process was simply because there were no maps on my OFT when it got to write portion of synch process. This morning before work at around 7AM cst I tried to finish synching and the write portion started after I selected the stage one map (current mods are Invidia Q300 catback, P&L overpipe, Invidia catless resonated front pipe, I always use 93 octane fuel). So then write portion did complete and the stage 1 map is now on my ECU as of this morning.

After synch completion of stage 1, I let the car idle for about 5 minutes (you are supposed to let it idle for at least a minute after initial flash). After that I checked CELs again. No CELs. I watched AFRs and they looked fine (mid-14s) while I started normal, non-spirited driving to work. Car felt very sluggish for the first 5-7 minutes for the first country road I drove. At stop sigh, I turned and tipped in throttle to about mid-point. Car sputtered a little. I looked at advance multiplier and it was still 1.00 so I assumed at that point something strange had happened with fueling and that was not a knock event. Unfortunately I was not data logging at the time. Continued to drive for an additional 15 minutes or so and got in town to my work area. There I started to tip in throttle a little more aggressively after a couple stop lights and stop signs. Around one routine 15-20 mph corner I tipped in throttle like I normally do. Tail go out a little on barely wet pavement, definitely more lively than normal as I've been around that corner in all conditions, ice, snow, rain, dry, and the car felt a lot more tail happy than normal – I attribute that to more torque at that point of the ECU tune getting accustomed to my car after the 20 minute or so drive into town. After that, I did two more semi-aggressive starts of about 65-70% throttle. Both times I had switched from snow (we got about a tiny dusting of snow last night) to sport mode on the AT and it felt AGGRESSIVE. I think this tune has made a serious difference even only on a stage 1 level car. I'm using 93 octane fuel. And it felt pretty damn good on those two slightly more spirited take offs from full stop.

I must say that the car definitely feels more powerful than it ever has on those last three slightly aggressive take-offs before work this morning after the car felt a little limp on the way in. I attribute that initial weak sauce to the tune's adjustment period to the car after the initial flash. The car felt really good after that.

Overall, I'm excited. I think this stage 1 tune, if it feels like right before I got to work this morning, feels pretty damn good. VERY noticeable. Not impressed with the email response time yet as I originally emailed about where I am in line with the OFH (I have that on order). That was on Friday. Have not heard back for that email. Emailed last night about the synch process problem (now solved), but I have not heard back on that one either. So customer service is 50/50 at this point (quick shipment and receive, slow response on emails so far). On a positive note for customer service Shiv did respond to one of my PMs right before ordering very quickly. The product itself seems to be pretty kick ass so far considering the cost point ($499 for OFT).

More to come….
