Efi computer help !!!
 

We have a 1990 Camaro 350 TPI Stocker, I/SA. We are upgrading our computer, etc. from an Accel Gen. 7 unit to a Holley unit. Is the Holley
550-601 the unit we should buy. Thanks, J.R. Haddad.

If I were buying an EFI set up for a stocker, it would be a FAST unit from Comp.

What these guys said ^

Re: Efi computer help !!!
 

Can't go wrong with FAST!

Re: Efi computer help !!!
 

Listen to these guys!

Re: Efi computer help !!!
 

The Holley is by far the best system I have ever worked with. It is very user friendly and comes with excellent customer support.

I have worked with the new Holley system in a couple of COPO cars. I much prefer FAST.

Re: Efi computer help !!!
 

Ed, as you know from our previous conversations, I have a very high
regard of your opinion. What do you prefer about the FAST system?
Thanks, J.R.

Re: Efi computer help !!!
 

Unless something changed since I helped Patterson and a couple other guys with their COPOs, I could not set the VE table break points. I can set my FAST rows & collumns to what I want. I have mine set to the MAP values I see mine running at, at the different elevations/Baro numbers I see mine running on the track, at the tracks around here. I use Speed Density, not Alpha N. Like, at Great Bend,KS (higher elevation) it runs on a row in the VE table (aka "fuel map") it never uses anywhere else. Don't have to change "tunes" for different tracks. I use an IAT sensor, and that correction table to correct for hot or cold days at the same Baro/manifold vacuum. Last Holley car I worked with had set values for fuel & spark table rows.

I also use different spark advance/timing in each gear. Never looked into how to do that with Holley. May be possible, I didn't think enough of that system to look into it.

Only upside I see, is it appears to support the LS coil on plug ignition system with no added control box. Single ignition coil, I would use FAST.

Ed, which FAST unit would you buy?
Thanks, J.R.

J.R.
Which Division do you run in? As a FAST customer myself, we're very fortunate to have the guys with FAST at various races throughout the year providing support and assistance to us.

Re: Efi computer help !!!
 

Nick, we run Division 5. Support in some areas can be hard to come by,
so we try to buy the right stuff the first time. I'd love to tell you we always
have, but that wouldn't be true. Thanks, J.R.

Re: Efi computer help !!!
 

All of the major systems currently available will get the job done. If you have any questions about the FAST XFI system, I would be glad to help.

I did have the winners of both Stock and Superstock, as well as the #1 qualifier in SS plus 14 class winners all running FAST XFI at the US Nationals last year.

As far as support, we have a team that specializes in NHRA Sportsman racing. I can connect you with one of our team members who can offer support via phone, email, and even remote connection to your vehicle if needed.

Re: Efi computer help !!!
 

Ed in the quote below you are using a different spark advance for each gear with a FAST system? You can do that.This must be an advance maneuver i don't know about yet, I am still learning a lot on my FAST system. How do you do that? Will have to call David. I meant to ask this question months ago when i first read it.

Re: Efi computer help !!!
 

Absolutely!!

Re: Efi computer help !!!
 

I did back in 2009... I haven't used any other unit.. But if it's any help. I would buy the FAST again... The guys are more than salespeople. I had David Page at my house one Saturday morning for over 4 hours.. He was between races in Florida but could have been playing golf, fishing or playing on a beach somewhere... But no, he was at my garage fixing my mistakes... You can't beat their service after the sale... I don't know what else to say...

What is wrong with the stock computer?

My 96 mercury cougar, P/SA, ran .2 over the index, runs well with the
stock computer and a SCT hand held unit.

For what you are doing, nothing.
