I had an STI in 2005 and had a very good experience w/ COBB, so I didn’t hesitate to jump in again with my GTR. COBB’s spent so much time/money on the AP for the GTR (not only engine management…also does transmision adjustment from custom launch control settings to clutch touch-points). The functionality for my application makes makes it a no-brainer. ---

Splices into the fuel return line, it has a 3/8" and 5/16" nipple for inlets and outlets. Other than that it’s just ground and a positive that’s switched with ignition. ---

McMaster sells the coupling reducers and many places sell the weld on AN fittings. LMK if you need help. ---

Travis, how many times have you tested the e85 off of 23? I live less than a mile from that station. I might get some big injectors and get a tune for that this weekend, then pick up the sensor down the road. ---

I live less than a mile from that station. I might get some big injectors and get a tune for that this weekend, then pick up the sensor down the road. A few times now. In mid April it was about 68 percent, and as of a couple weeks ago it was sitting at 74 percent. Keep in mind that what’s important is keeping your content consistent while tuning, and not the overall content. From what I’ve seen so far, a good tune on E77 will run anything from 70-85 fine. I’ve personally witnessed NO change in AFR when going from E81 to E76 (logged multiple pulls, not just glancing at the wideband). Eventually I’ll test from 70 to 85, etc, and record any changes. ---

TurboTravis, I didn’t measure my ethanol content % before getting my tune in March, but now after reading some of your measurements, I’m thinking I am wrong to assume it was E70 in March. I was under the impression that this region dispensed E70 in the winter, E85 in the summer…and the times in between were somewhere between the two (in other words, there was only a 15% range). From what you’ve analyzed, it sounds like you’ve seen a seasonal range of more like 30%…which makes me wonder if I was pumping ethanol in the 60’s. I did a few datalogs now and see that my fuel trims are adding some fuel to avoid going lean, so I’m working with my tuner to get things back in line. Make sense I might be seeing the trim situation I have if my original tune was on E65 and I’m pumping E80 now @ RT 7 Mobil? ---

Make sense I might be seeing the trim situation I have if my original tune was on E65 and I’m pumping E80 now @ RT 7 Mobil? Well, as of right now, I’ve seen a swing of about 12-13 percent (E68ish at exit 23 in Mid April, and E81ish at the Airport Mobil last week). I’d venture to guess that your tune in March was on E70(ish). But if you’re car is truly in closed loop all the time, it should be making corrections for ethanol content ‘on the fly’. Regardless, from what I’ve seen so far, I don’t think your car would be dangerously lean on E80 if it was tuned on E68-70…given the fact that I saw NO change in AFR’s when going from E81 to E76. If there is NO change with a 5 percent swing, how much will there be with 10? You gotta realize how LITTLE gasoline it takes to change ethanol percentage. For example, to turn 10 gallons of E80 into E70, you’d only have to add 1.25 gallons of pump gas (to the 10 gallons of E80). BTW, I really want to check out your car sometime. PM me with what it made at the wheels… ---
