Who uses E85 in their V8 commodore?

[macca_779]

Dual tune PCM from doubledip I think that's his username, I'm still yet to get one but when I get a bit more spare cash I will for sure. 2 tunes, run it low and fill up or drain the tank. Easy.

A flash tuner like an autocal is another alternative. That way you can have a few different tunes with varying % of ethanol content.

So what controller will you be using? As soon as I fix my cold dynamics tables, I'm going to try flex fueling mine using calculations as I don't have the sensor.

[Brett240]

I can guarantee that I and many others have experienced no ill effects from running high % ethanol fuels.

You hardly need a lab to test accurately for ethanol content either.

I fail to see how you see it as having hardly any benefit. More power, cleaner engine, cheaper/km and better for the greenies.

Only real con's to the fuel is increased consumption. But that's mitigated against the price so its a mute point.

Hi Macca, what method are you using to test for Ethanol content? just out of curiosity, no further points intended.

A test beaker and a bottle of water

I have one of these, an overpriced tube lol. at least it has lines on it

as said before, eflex ~75% but united I did a test and it was well over 85, closer to 90! Rocket fuel!

Ive ordered 2 of these kits a while back (Havnt used them yet).

Look pretty good for the price though

[bush_basha]

can a series one VE run the ethanol sensor like a standard series 2 and your right to go with mixing fuels E85 and ULP? or is it a little more involved

[swingtan]

The settings are in the tune, it's just a case of tapping the sensor into the fuel line and running the wires. I "think" the pins are still in the ECM sockets, but may not be in the existing look plug. So you might need to get that pin added as well.

On another note, I turned on the fuel trims last night (first time in 4 months) and averaged wel withing +/- 5% so I think I'll turn on the flex fuel tables tonight. It'll be a "calculated" ethanol percentage, as I don't have the sensor, so we'll see how it goes. I need to rest a number of fueling and spark tables to do this so will need to do it when the engine is hot and the O2 sensors ready to start correcting.

Simon are you using the std fuel pump & injectors with your setup? When I inquired @ my local shop was told it would be mandatory to upgrade for more power.
Not sure if this is really necessary & doubt an L77 engine would use a larger pump or injectors compared to an L76.

I'm not 100% sure, but I think it has an upgraded pump. Don't take that as gospel.

The L77 cars do run a much larger capacity fuel pump

Great thread guys, mine is a VZ/E38 car if I were to consider this I'd have to add a Sensor due to the nearest e-85 being a 150km round trip.

The Tables are all there so is it still just a case of wiring the Sensor to the PCM?

[swingtan]

Running stock fuel system on a cammed L76. I did max the injectors out very early on with E85, but I was running too rich up top. Once I pulled back some fuel it's running fine.

[Micks]

Thanks Simon in an L76 std injectors, std pump what's the est pwr figure without an upgrade?

[dogsballs]

mine was 276rwkw with exhaust and mafless tune on e-flex.

i run a bit of comp and a ls2 cam, then changed to e85, maxed fuel pump then injectors, so swapped to Ls9 52lb and an aeromotive 340 intank (which recently died so replaced with walbro), making ~300rwkw thru big stall.
