Hey man, how’s your Z doing? Anyways, I pretty much have the same setup as you it seems. 2016 Nismo with G3 CAI and Motordyne CBE. I was wondering if you got the MD LTH and if you dyno’ed your Z yet? I hope to make mid 330whp at the very least, 340whp would be wonderful and just wanted to see where you’re at if you did install those LTH?

Flex fuel. 91 octane and e85. Zeitronix ECA-2 and ethanol contect gauge that came with the ECA-2.

My G37 is flex fuel tuned with ECUtek. You just need the sensor of choice and wire it in by bypassing your EVAP sensor. I'm also NA and got about 15 more WHP when at or above 75% ethanol; but I have...

The very function of the FlexFuel feature is to detect the ethanol content and adjust the calibration around it. The 2 absolutely necessary components of FlexFuel is the sensor and engine control...

I was under the impression you needed slightly larger injectors and a fuel pump since E85 needs a lot more fuel volume to be delivered.

FWIW the Motordyne headers paired with a single exit exhaust make these engines SCREAM. If this car wasn't my DD I would 100 percent run this set up. Also between these options you're sweating...

It'll rev up faster, but it'll be a little trickier to launch. It definitely makes the engine feel more responsive. If you're already in there doing a clutch, spring for the flywheel. Expect more...

I got the inspiration to test E85 on the Z and see what kind of quantifiable gains can be had. Not hearsay -- but actual scientific data collection. Thank goodness for these things we call dynos! ...

600cc would just barely be enough. I see no reason to not go larger since the pricing on injectors under 1000cc is mostly the same or very close. You would not need to upgrade/replace anything in...

you will NOT save money changing to E85. It will cost you around $1000 for quality injectors, pump, and retune. You will never see that money back. Fuel mileage drops CONSIDERABLY after you switch....

Right, doesn't e85 usually result in a pretty substantial drop in mileage? It's about 30% less energy by volume than pump gas and that's why you need more volume than pump, right?

If you're interested I have a set of GTR injectors laying around. I just finished 3 G37s that I had tuned on E85. I've done both Flex fuel or just map switching between 93 and E85 and honestly...

I just bought used GTR injectors off eBay for $100. Then had a E85 tune and two gas tunes created using EcuTek. If I get low on E85, I just pull into a station and switch to a gas map using the...

if you are staying N/A and want to go E85, the only thing you need are injectors, most popular being GTR injectors. If going boost you'll need a bigger pump. Uprev will allow you to switch...

Is anyone running E85 with a full OE fuel system and basic intake/exhaust mods? I read in another forum +20 hp increase just from fueling with E85 and tuning it but never got a response as to...

New pump and injectors. Then tuning to advance the timing to the four winds and lean it out to take advantage of the extra octane boost and cooler fuel. Just don't expect crazy power gains.
