Thread: EFI Options

Tweet

Long time lurker here, and since I've recently waded into the EFI pool for the first time I thought I'd weigh in here (if that's ok)-

There are many good EFI systems out there (FAST, MOTEC ($$$), Big Stuff and Holley come to mind)-

I was originally going to go w/FAST, but I have a BBC (540) that I wanted an induction system that would make a statement and give me good driveability, so, I went with the Hilborn and the Holley Dominator EFI-why?

The Dominator offers the ability to control an electronically shifted automatic-I have a 4L80E in my Car (if Jake's Performance ever finishes it), and, it has the fastest processor out there right now.

I would tend to agree that sequential is better (which most all of them can do), but for most a batch fire would work very well also. I think it really depends on how much control you want with your engine-do you want to control Spark? DIS? Trans? Nitrous? Do you want drive-by-wire? Data aquisition? Are you running a Turbo? Water injection? Would you like to be able to store more than one tune?

All of this and more are available now-I went with the DIS option (distributorless Ignition System and sequential injection, which necessitated running a Cam Synch on top of a Crank Sensor)-

When you open the Box and see everything that comes with it, it's a bit overwhelming, but as you go through it's pretty cool too-it's kind of like when this Internet thing came out-I was intimidated at first, but then my inner 5 Year old came out and it got better-

Go ahead, wade in there with me (we can drown together)-just think-one day you could walk out to your Car without getting in, reach in and turn the key only to hear that sweet music, and stand there revelling in the fact that you did it yourself-if someone had told me you could do this 20 Years ago, I would tell them that they were nuts-here is a picture of my engine fresh off of the Dyno-

Oh man, now you're going to have Severson drooling all over his keyboard If that engine had the distributor on the other end I bet he'd be heading your way wanting to carry it back to South Dakota EDIT - SEE?? He was already typing!! Must have put Saran Wrap over the keys Dave??

Seriously, I'm very glad you waded in and gave us your experience. I've never talked to anyone running the Holley EFI, so your comments are very much welcome on this and any other subject. I've found that a lot of the companies are using Fast's processor, and then putting their spin on it with peripherals. Does Holley have their own?

My understanding is that Holley originally purchased the Software from another Company , although the processor is rumored to be theirs-what I like about the Holley is the self tuning feature-you simply install a program that is close for your engine, start 'er up, hit the self tune function, and you can watch the Tables change as the rpms
go up-watch this:
