Any Engine Electronics Experts?

[FABRICATOR]

Are there any electronic engine management experts here??? Need to know about building a powerful and reliable system. (P.S. not for smog or rice grinder)

there's more companies but i cant think of them right now. I dont think that these ones are for rice only, they should handle any type of engine.

My buddies dad had an acell DFI in his 383 s/c trans am and it worked good, but i think that systems kinda old.

Eric,
In simple terms, I would like to control fuel injection and ignition timing on a mildly tuned but large displacement V-8. Reliability is paramount along with instant throttle response, and a flat torque curve. One idea is to graft an LS1 management system onto a standard V8. The other is to use the LS1 coils with an MEFI 4 ECU (made by GM for Marine use. MEFI 3 comes on current 350 and 502 Chevy Ramjet engines). Fuel management would be by the same ECU and work with a twin 58 MM throttle body and a long, tuned runner manifold. The LS1 ECU is sort of a complicated animal and requires a ton of inputs, including mass air flow, O2, etc. Can it work without some of the inputs?? Or work with dummy inputs??

IMHO some OEM systems are more reliable than aftermarket. A simple crank trigger MSD ignition system is reliable and is OK for drag racing but has no timing advance. This has to be done with a second "magic" box. Same thing with EFI. A Holley or Accel EFI does'nt control ignition. More boxes. MSD has a new coil-per-cylinder system, and I suspect others will follow. This system is very expensive and does not provide for EFI. IMHO at this point, most of the aftermarket is years behind what the OEMs are doing in performance applications. Engineers at Delphi claim a 100% increase in power at the spark plugs just by putting the coils there, and with less power consumed. The system will run on as little as 8 volts and timing is very precise. I'm sure it can be done to work in an off-road racing environment, but I have not found anyone who has ventured into this stuff yet. There are some LS1s out there now in some Class 1 cars and they're not missing a beat.

Electro Motive = less expensive and very reliable.
Mo-Tec = very expensive but very high end system.

For your use Electromotive will work great!

Steve Dose at Lethal Does injection is the man. He wire wire it up in house. He also uses a chassis dyno to map in the system.

I have had the Electromotive system going on 3 years and not 1 problem. The new Tec 3 system does some amazing things.

Try Steve Dose of "Lethal Dose" fuel injection in El Cajon. I'll post the # tomorrow (it's at work)

Chuck, We dyno'd one of those 502 RamJet's @ Ken's Automotive. That ECU is only just sophisticated enough to make the engine run. Wasn't too impressed with it.
Another aftermarket ECU to check out is: http://www.ronmorrisperformance.com, I think) has put them on all kinds of stuff.

I have the SDS set-up on the barge. It is easy to tune and extremly reliable. For the price, it was the best mod I've done to the (soon to be retired) hunk'o crap......
