Thread: BG 6 Shooter vs Edelbrock Dual Quad?

In theory you can get any progammable EFI system to do exacty what it needs to from cold start on up. If I was that PO'ed at my EFI and my car would pass inspection without it then maybe I would dump the EFI and run a Speed Demon from BG. Not likely though, I would probably fix the EFI.

I do have a serious question here casue i have been thinking about EFI.
What do u mean u had chips burnt did u not program this yourself or get a programable ecm. cause my question is if u had a chip burnt that makes me assume that u never brought the vehicle down to a chassis dyno where they will for some coin tune your ecm for you. and you had it burnt also makes me assume that u called some one with your engine specs and then they mail the chip to you. which my question is how can someone do something when they are not tuning it for all situations full/part throttle and cruising speeds. just wondering cause i'd like to EFI someday but i read stuff like this and i get shy'd away cause i dont wanna spend money on something that i am not gonna like


hope this all makes sense

pre burnt chips if done right for your setup will work close to right, and depending on the system, you'll have active fuel trim, which will run off the tables in open loop til she warms up and then try and base the fuel trim close to the table but also run 14.7:1 AF ratio.... the problem is on the systems that are burnt to run stricktly off the table in open loop, they dont accomadate the fact that engines built 500 times with the same parts aren't going to run exactly the same, plus the weather and altitude can change effects too..... i reccomend if you want to do EFI make sure your system is going to allow closed loop with fuel trim capabilities..... and reprogrammable fuel tables... and its even better if you can use a fully electronic ignition so the computer can control advance as well.... maybe even a distributorless ignition.... thats why i'm thinking of building my own coil on plug system.... i'd reccomend maybe taking an ASE engine performance levels 1 and 2 classes at a local college so you can really get the theory
