Pros and cons of AEM, Holley and MS3pro

[cjsgarage]

We've had lots of silly issues with the newer FAST stuff and some issues with the other brands, too. Have you looked into BigStuff3? He's the author behind the early ACCEL units and the SpeedPro units/early FAST boxes.

i'm also really happy with the tunability of the factory GM units using the HPTuners platform, but they don't have auxilary inputs for extra data aquisition obviously.
I should add that the HPTuners platform has custom Operating Systems available which allow Boost Enrichment, and tunability for other power adders (while still using an OEM ECU). But this is obviously a solution for the factory EFI GM engines 97 and newer.

I'm very early in on running my car but I have the Holley Dominator. Went with Dominator over HP as I am using a DBW TB. Really like all the input/output options I have. Seems endless to what I can run.

I do have dual O2's, has boost control, manages the fan with PWM C6 controller (like the thread on this forum clearly explains).

It's just a nice piece. Setting it up and starting the car up was simple. Configured it for my setup and had the car started after wiring it in minutes. GUI is pretty good also.

X2 on the BS3 reference.

Big Stuff 3 efi is used by many of the top drag racers in the country. BS3 has been around a while and is also one of the first aftermarket efi systems that has been able to control late model GM electronic transmissions. For any of you who want to read a little bit about John Meaney of Big Stuff 3, check the following article.

Sorry, but BS3 is so 2001. That box is seriously outdated.

The software was just updated this year for BS3 users and, again, BS3 has been able to control late model GM transmissions many years. It wasn't until about 5 years ago, that you could get a Holley Dominator which is able to do that. 2001 puts BS3 a good 10 years ahead of what Holley Dominator systems have just been able to match.

Megasquirt just released MS3-Pro Ultimate at PRI a few weeks ago. Holley efi must be outdated and so 2011 now

But none of those have the processor that the AEM does.
And BS3's claim to fame has been with the drag racing community largely because of it's datalogging capacity. Drivability however isn't as good as some of the others.

The Holley EFI systems have amazing data logging capabilities and drive awesome.

Bs3 seems to work pretty well for the world's fastest street car. I'm not saying there isn't a lot of great stuff available on the market today, but I would definitely say a used bs3 or fast xfi system can be a very good value.
If purchasing new I personally would take a good look at the haltech elite 2500 or the fueltech systems myself.
