I have been running the ProEFI for 5 months now.. Local tuner helped make my decision. A few things I would change, but so far I have been very happy with it. 246mph and improving with every pass.

It took me a while to get used to the interface compared to EfiLive, but now that I am used to it its not bad. Online changes at the track are easy, offline changes take a while to build the file and download.

Now if I could only get 8 egts into it.

Have you helped any with a c6? The more I research Holley the more I want it

No. Just a couple older vehicles with LS motors.

I will say its very adaptable because you can program anything and everything. I use the factory 4l80 output shaft sensor as a speedo and driveshaft speed. This lets me setup traction control in the holley software. Also, the data logging is awesome. I use outputs for: pwm fan, progressive nitrous, shift solenoid, second fuel pump, and a/c cut off. The possibilties are endless. Once I go to turbo, it'll be the boost controller also.

If you haven't already, read up on yellowbullet.com (electrical section). Great Holley tech and info there.

I had the basic unit, it was going into an lsx fox I was building with a friend but he parted ways with the build before I had a chance to mess with it. I've read up a lot on them, just haven't found anyone besides franz that used them on a c6. Was hoping to get some more info on installing it on the c6 and how everything else was setup(ignition, ac, etc)

Actually, you don't need the box. The Davis system pulls timing, based off wheel speed and driveshaft speed. Two local friends(actual friends) have dominators, and have the system pulling timing when it senses wheelspin, based off the two inputs(wheel speed and driveshaft speed). So you do not NEED another add on, just gotta know how to tune it and set it up.

As for the Davis Technologies HOLLEY compatible box, it RETAILS for $999.00(self learning optional unit) Which is more than affordable for a functional system.

Installing a PROEFI on a customers car very soon, ordering a dominator for my car probably tomorrow. We'll see how they both stack up.

Is your car a c6? If so, it would be greatly appreciated if you posted up how you do it.

Smoove

Negative. Holley car is C5(not CAN obviously), ProEfi car is C6.

Dude_man

Meh! You guys keep getting me excited then shattering my dreams

Smoove

Preparing you for life my friend.

:cheer s:

Lol I'm used to being the Guinea pig.

Smoove

lol likewise

Ran a Holley in a turbo 408 vega drag car. Easy to tune, easy to setup, ran awesome. That car didn't have any other systems to talk to, and no fancy features. Its a great setup for a race car, just not sure about street application in a c6.

Franz said he liked it, he had it working with the factory cluster etc. Which I don't really care about since I'd rather go with a racepak anyways. I just want to retain my ac features. Which I believe is through the bcm?

We just started wiring in the pro efi in this 05. Do people use the factory ecm with this? Doesn't look like we need to based on schematics. Ours isn't plug and play since we have the douchy 05 we're working with.

Dude_man

Mine is an 05 too

Smoove

uggh.
