Very nice. Thank you. Hadn't thought of faking it out for other uses. Creative thinking.

You only need one tune, and it adjusts on its own.

Haha, thanks!



On the topic of integration in other ways with a signal generator... Here's an example of somebody who used it to add timing when the meth system pressurizes.

Shawn from Lethal used one to modify timing with a nitrous system.

Great writeup

thanks for the hook up!! noo injector needed?

Nice

To enable it in the ecu you don't need anything but what he posted. To run e85 you need whatever fuel system to support the power you want.

DSteck

You need fuel upgrades to support your power. This thread was only intended to explain what needs to happen to add the functionality.

Unfortunately HP Tuners doesn't support all of the E67 applications (ZR1).

Anybody that needs help getting the parts or getting it set up, feel free to PM me or email me at dsx.tuning@gmail.com. I've done it on a lot of stuff from GTOs, Camaros, Corvettes, and G8s, CTS-Vs... To swapped stuff like a 67 K20 truck with a turbo 408!

Awesome write up indeed props to you - I just wish there were more pumps available in Maryland

DSteck

That's the beauty of this. Even if there's only one pump, you can still fill up with it once in a while and not have to screw with the tune.

Excellent Point

I have a running/driving LSX Nova that I am looking to go to Flex Fuel....

Right now, I have a 2001 LS1 Camaro ECM with a 2003 5.3 and the camaro T56.

What should I do to get to a E38/E40 set-up?

Do I need to buy a new harness or can I change the connector ends on my current harness to hook up to the E38/E40???

Thank you

what do you feel are the direct benefits of flex-fuel?

DSteck

Here's my take on it. E85 is basically cheap race gas, and boosted cars loooooooove it. There's one glaring problem though... It varies WILDLY from station to station. Beyond that, it isn't always available.

Using a flex fuel sensor solves that issue. The sensor can accommodate the ethanol content variance so you don't have to use some backyard chemistry test tube kit to check the fuel you get. Ethanol not available? That's OK, fill up on gasoline and be on your way. There's no need to flash a different tune if you have to use gasoline. You can go on a long road trip and not worry about having to map out E85 stations.

Long story short, letting the computer seamlessly make adjustments for whatever you put in the tank beats the hell out of the alternative manual methods.

SteveDoten@ARH

Nice work.

J Christensen

thank you.

given that and the differences of performance off of a specific fuel, what would be the best way to do a custom tune on your car?

DSteck

Umm, just do it. I don't really know how else to answer your question.

It's easy to get it running but takes a savvy tuner to really optimize it.

Thank you for the Great post! I plan to do this in both my C6 and my escalade! when I throw forced induction on my rides this will be awesome!
