Done any eflex testing on your dyno gauge Mick?

[ratter]

none

Just throw a bit of moonshine in the mix.... it'll run sweet and get everyone around you, including yourself (if you have a surge) tipsy

Rednose, caltex are telling you fibs. It's common knowledge that caltex change their ethanol content in winter and in summer. In winter they take ethanol out to aid cold starts. It's much more than a 1% difference year round. For them to tell you it's only ever changed 1% is a blatant lie.

United e85 is very consistent. No it's not e85. It's actually closer to e90. But consistent.

From my testing they seem to be very close, why would they tell fibs?

What do they have to hide?

In regards to United being 90% from what Mick has seen on his dyno its more like 83-85, BCL's Zeitronix shows United to be 85-87.

The only time I have heard of people saying United is 90% is when its tested with the test tube.

Once the Zeitronix goes in I will then keep you posted on my findings.

Good way to compare and gather data with a quality unit like the zeitronix gauge

If enough people install them it will be quite clear which brand of e85 will win the consistency award sooner or later

Caltex don't want to scare customers into thinking their fuel is constantly changing. People then fear damage. Considering eflex is aimed at cars with ethanol detectors in the tank, law of averages says 99% of cars won't be affected by ethanol changes as their PCM automatically adjusts to compensate. However, in our case, our PCM does not do this.

In regards to testing united e85. It's all relevant. If you always use a test tube, it's relevant. If you always use the same electronic means, it's relevant. Both systems prove it's consistentancy. As long as you always use that system.

Why would they scare customers, this fuel was never targeted for guys like us it was meant to be used in flex fuel cars, so it doesn't matter what the percentage is as the cars ecu will make the necessary changes.

In regards to the test tube, if you use the same test tube it should be the same but how can you guarantee the same amount of fuel and water are put in every time?

This is why an electronic gauge that takes the ethanol content live would be best.

Agreed Jet, and I am not saying either is better, I just like the fact that I have been running the eflex for almost 2 years with no issue.

Maybe its the tune, but I have not experienced any fluctuations in AFR's, have not had any cold start issues and have not had any change in the way the car drives since it was tuned almost 2 years ago.

Everytime the car hits the strip it runs consistent times and MPH, everytime the car is on a dyno (DD or Mainline) it is always around the 390 - 410rwkw mark and AFR's spot on.

May try a United tune but I'm just not sure how much more power can be made on the stock turbo.

Hypothetically speaking, would it worth someone's while to run an aftermarket ECU that can support a flex fuel sensor ?

Wouldn't you then be able to go from Eflex to E85 from a barrel without changing the tune ?

EDIT: Something like this
