Lol. Get a new tuner.

just take 6 - 8 x 20L fuel tanks with you and do a fill up every 2 - 3 weeks

I was going through 20L in 7 minute sessions at Sandown. lol.

No, they all vary slightly... But it makes very little difference to your tune.

If you tune on the leaner fuel (United) it will run fine on any e85. (Caltex, Powerplus, Drum e85.)

I have been running various e85 fuels over the last 4-5 years with 20 or more tunes, some very lean, some rich. I had quite a few issues during that time that should have blown my engine, like wastegate lines popping off (running over 50psi) and fuel reg/map sensor hoses leaking vac, leaning the tune out to 20:1 on cruise. It still ran fine, no melted pistons or det.

It really is the ultimate fuel for turbo cars, no matter what pump it comes from.

Thanks for the reply. The reason I ask your opinion is that out of the three tuners I have spoken with, two of them have been adament about using either an eflex sensor as Caltex and United's ethanol content can wildly vary, or sourcing from a racing supplier to ensure the ethanol content remains consistent.

So basically what your saying is that regardless of variations of ethanol content, one tune on United e85 is enough to cover the variation in ethanol based pump fuel, and the variation in ethanol content won't damage my engine regardless?

EDIT: This is for a track car only if that makes any difference. Also don't plan to be running huge amount of boost either.

Its true that the ethanol content can vary a fair bit but if the tune is safe on the highest content of ethanol eg united stuff can go up to e90 anything thats got more petrol in it eg e70 etc your car will only run richer which wont hurt your engine anyways. Mate speak to Yavuz at unigroup engineering give him your car and never worry about ethanol content or any of the other rubbish these other "tuners" have been feeding you ;)

Hes tuned both my cars both drive amazing have great fuel economy and have NEVER died :)

Had my car tuned on united over 4 years ago and I have never had a drama with it.

My tuner has tuned literally hundreds of cars on e85, a lot of cars making 1000+hp and united is always the fuel of choice.

Exactly. The only reason you would need an ethanol content sensor is if you plan to run petrol one day and e85 the next, without draining the tank.

A 10% ethanol variation is only a 2% fuel variation, and perhaps 1/2 an AFR point. As long as it goes richer not leaner there will be no issue at the track or on the road. Sourcing race fuel in drums will only help lighten your wallet.

Why won't you be running much boost? My stock VQ loves track days at 30psi... :)

Who in sydney is famous for tuning on E85? I'd like to hear some feedback from the people. How does Nistune go for E85?

I have to upgrade my fuel system before I get tuned regardless which fuel I run so E85 is looking good. Also the United at Dee Why sells it and I have an empty 200L drum in the garage

Most of the tuners do it now, jem have a good reputation on it or if you happy to go north a little dvsjez has some great results and will go the extra mile to make sure it's right

Why would you stick another ethanol pump right near the other stations? The map shows they are all stacked into the same area of Sydney...

Save on transport costs maybe.... Lol. Clowns!

I mentioned to SK when the new "Yagoona" United servo got E85 and he reckoned that a while back when the price of all fuels was really high in Sydney the dough was going into new tanks that are ethanol compatible .

I agree it's easy enough to tune for E70-E85 and the only disadvantage is you'd use more fuel with the higher petrol contend mix . If you were tuned to run exclusively E70 and the light load and cruise mixtures were set for economical running it's real easy to bump E85 up to E70 . Assuming they are 15% different that's a whole 8.25 litres of petrol in a 55L tank so if you were dry adding that then filling with E85 is no drama . Close enough to 2L per 1/4 tank .

I was reading recently that late flex fuel cars don't use these sensors and if that's the case they must have really sophisticated oxygen sensing and knock sensor systems and the ability to self learn really fast .

      R32 GTS (RB20DE) Injectors Replacement

      My bad, I unplugged the one underlined in red instead of yellow before. With the car started, after unplugging the IACV (the one underlined in yellow), it idled at around 400/500 for 3 seconds before stalling. Attempting to start the car without the IACV will not start the car.   It does stutter and sputter for around 5 seconds before dying. However, immediately after starting it, you can already hear some slight sputters from the exhaust.   It won't start with the AFM unplugged. If it is when the car has already started, it stalls in a few seconds.   Yesterday, I did take some logs using Nistune of 3 scenarios. Car idling till it stalls Car idling and unplugging the IACV Car idling and removing the AFM I also have some previous logs of when the Car is idling till it stalls and when driving and it cuts. I am not really knowledgeable enough to understand what to look for. After every test, car idles rougher and rougher, until I have to stop. It will be fine the day after.

      There is no difference between a 17x8 and an 18x8. The total diameter of the tyre needs to remain +/- the same (so you don't mess up the gearing, speedo reading, and clearance when turning front wheels..... so you just need to use a lower profile tyre on th 18 than you do on the 17. /rocket surgery.

      I thought the same to start with. But then I thought it was one of those LCAs where the end of the ARB goes through a bushing in the LCA itself, instead of having an end link.

      Duncan's V37.......race car?

      To re-cap, I bought: https://www.alibaba.com/product-detail/Lsailt-8G-Infiniti-Q50-Q60-2014_1601171829627.html?spm=a2756.trade-list-buyer.0.0.2cd476e9FTIlKE As you can see, if I bought 20 it was $653, but I bought 1 so it was $1,170. I was very tempted to buy 2 and resell 1 at 25% cheaper. @MBS206, I am not sure if they do a Kluger one, here is their list but it might be there under a global model name: http://www.lsailt.com/product/android-interface?page=1 Keep in mind these full android replacements have basically all the bits a phone does (cpu, ram, storage, wifi, bluetooth, usb interfaces) other than a screen (it uses a host), thus the $800+ cost. Android Auto screen mirroring is MUCH cheaper as it's just a cut down shell, input mirroring and output mirroring BTW I also need that "screen off" feature, it is much harder to see wildlife even if a dash is reasonably dark. Both the Fuga and V37 have display off buttons for night use, they just come back on for a second or 3 if you interact with it, eg skip a song.
