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 .

      RB25DE NEO with Haltech ECU

      By feartherb26 · Posted

      If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.

      This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).

      I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.

      You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?

      Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
