well piggaz has seen 77 up to about 87 at united servo at rozelle. I'm not a tuner, but suspect that if your car is tuned on e85 and your buying e77 fuel (or potentially worse) then you could run into some problems.

agreed...caltex consistent. More of an issue for united.

That's not how most tuners would tune, as that's not safe.

Safe tune, variation = no problem

We test daily UNITED is the only pump fuel we recommend (caltex is average). So much so that we dont use drum.

A tuner should tune any pump e85 car to be safe on any thing down to e70 (just in case you need to fill with caltex etc) as its a very minor change in tune.... and minimal loss in hp... very minimal

I love reading these threads and learning all this shit :) I wish I had the money for a flex tune and an ECU that could handle it.

At one stage I was even thinking just going ethanol but there is only like 2 servos that stock it here and none down the coast where I do a lot of travel

The GM sensor is available for under $100 delivered now, and with a Zietronics box should work on nearly any ecu, as long as you have a spare 0-5v input... Must speak to you about that soon Trent, I have an Emanage Ultimate to flex tune. ;)

Flex tuning will definitely be getting more common in the future. I need to fit a sensor to my Fcon but I am scared of the wiring nightmare in the dash. :unsure:

i think what people are forgetting is that if your car is tuned on e85 and your next batch of fuel you run is 70% your car will run slightly richer then normal, there is no "running lean" or "cracking pistons" situation.

I'm the opposite, was tuned on 70 and now E85 is available near home, compensation is in the ECU but going to check it properly on dyno to be safe

Yeah but Simon's point more revolves around the fact of someone not having a sensor and so on - which comes back to a lot of other posts in this thread that are quite clear

If the tune is done safely for a street car, the variation from E70 ro E85 has no bearing.

Whilst this thread is a good idea - as long as the tune is OK - It's a non-issue

Piggaz saw E68 at my local eflex pump few weeks ago in Richmond. Ive had my 33 and now my evo 9 tuned to run on that stuff with no dramas ever in the last 3 years.But im flexing the evo soon :)

Nathan what if you are going on a car trip like 3 hours away for a weekend?

Jerry cans?

Yep got 3 large red plastic ones, whether it's a trip to Winton, or going away. One day I will change from the power fc and get a ecu that can do eflex with a ethanol sensor. It's not a problem at the moment

      Meh. I "see" a typo above, that should have been "sell".

      Nismo copper mix twin “pull” pedal height engagement

      By joshuaho96 · Posted

      The clutch pedal has a procedure for adjustment. This can only be done after you are 100% sure the system is absolutely free of air bubbles. You must bleed the clutch master cylinder first, then the "separation pipe" which is the clutch damper line, then the operating cylinder as detailed in the service manual. Also, you must fully depress the clutch pedal between shifts. Just because you can't feel it grabbing does not mean the input shaft is truly decoupled from the crank. At high RPM clutch plates are vibrating and moving around, you need to give it the best possible chance of success. On the BCNR33 Nissan revises these adjustment procedures slightly but not by much: I would be careful with trying to play games with these adjustments. As for the Nismo operating cylinder they say a lot of things. In practice the twin plate clutch needs less movement on the clutch fork to disengage because the whole stackup of the flywheel + friction plates + pressure plate is much taller. Personally if you find that the clutch still disengages too high at the top of the travel I would try the Nismo operating cylinder. Make sure to follow the air bleed procedures.

      Thank you for the links. I’m going to go with the 6pin plug you used. next step is rust treating re painting dash support bar and steering column then the 6pin cradle plug when it arrives in the mail.

      I don't how much the car makes a difference or whether it is just a question of gearbox and clutch. On mine it's fine. Pull type Nismo coppermix twin (standard, not competition) on the 5 speed in my Stagea. OEM slave cylinder. Bite point is a few cm off the very bottom of the pedal. Clutch pedal all the way down to put in gear, and when heading off at the lights, there's a tiny bit of nothing and then it starts biting. And fully engaged before the pedal is all the way released. There's a bit of play at the top where the pedal does nothing anymore. Are you in Australia @ck_chino? If you are set on using a Nismo slave cylinder I have one new-in-box at home. Ordered it together with the clutch but didn't get it fitted. We can work something out if you want it

      I am using a pull nismo coppermix twin in an r34 getrag box, had both the standard slave and  then the nismo one. Adjusted pedal to get bite point how I wanted , it is on the higher side, but would fully disengage past half way down.  I also read that the nismo slave won't work but I had no issues with the stroke, might become one later as clutch wears but 2+ years of happy motoring so far.  Take the above as one input only, specially as my setup is a bit unique in that I am using an S15 clutch master , cefiro clutch pedal, custom braided clutch line. Lots of variables at play.
