Pros and cons of AEM, Holley and MS3pro

[funcars]

Since I'm not running DBW, using a manual trans and no boost for now I'm probably OK with the HP instead of the Dominator and it does save a bunch of money.

Thanks for the help

I haven't seen a car running the AEM ecu, tons of MS3 and Holley installations though. Holley seems like the way to go, tons of support and a proven product. HP or Dominator just depends on what your goals are.

Sounds like you got it. Where in norcal are you? If you need some help getting it running when the time comes, let me know.

And the good news is down the road if you change your mind on the ecu, it's a very easy swap between HP and Dominator. Simple check box on the tune and the two plugs connect the same way and just more expansion slots.

This is very good to know, as I just upgraded from the FAST 2.0 to Holley HP with crank trigger and MPI on my Shafiroff 540 Ultra Street. Should get dyno tuned in the next couple of weeks.

Imo the Gen 7 was one of the best "driving" systems for a very long time.

Check out the AEM, really cutting edge stuff. Super fast processor (400mips), loads of capability and easy setup and tuning. They'll be introducing the new lower priced 308 very shortly. It has virtually everything the 508 does except it's void of the DBW and VVC. Plus it'll accommodate dual channel O2's. Sounds like that would be better for your application anyway.
Their software and support is very good as well. I personally have had some issues with trying to get someone on the phone at Holley, and email requests have normally taken a couple of days.

But whatever you do, take your time to check them all out thoroughly. Download their respective software and check it out for yourself. That will tell you a lot about the system and it's capabilities.

Hope this helps.

Hi Mark,

Thanks for the info on AEM. I found the announcement on their website. I prefer having a built in wideband controller so the more expensive 508 would be the best option for me. I like that it can do on the fly map switching (I have an EFI motorcycle that could do that back in 2002) but with a harness it's a bit more than a Holley HP set-up. The map switching feature might be a reason to choose it as long as the hardware is robust.
I know AEM has been a big player in the import market and it looks like they are trying to get some volume from the V8 crowd now. I saw a few of the recent magazine articles (seems more like advertising though) and really wanted to get a more unbiased view but there is very little out there. Your idea to download the software from the various vendors and play with it is a great idea.

I agree that the Gen 7 EFI worked pretty well once you figured it out - it's just the documentation you could get as a non-installation center user was very weak. Accel seemed to be targeting the hotrodders that did not want to do work themselves and that was frustrating when I was helping a friend tune his. I don't think they helped themselves with their business approach.

Thanks

Accel supported their dealers first, not the privateer. The problem was too many of their "dealers" had no business selling EFI systems. That was, and still is an industry problem.
I know someone who recently put the Infinity 508 on his 8 stack 447 SBC. 8 stacks can be very finicky but this runs really really well. Let me know if you'd like to get in touch with him. He'd give you the honest scoop about the tuning and it's features and benefits.
