Fuel Injection
Fuel TechThe good news about EFI:
It is amazing; Flexible, Powerful, Reliable, and can produce bullet proof Torque and Hp and add built in engine protection only modern electronics offer.
***We now have the ability to reprogram some stock ecu's. This is by far the best dollar to performance ratio as the stock control units are as good and as flexible as the high end units below. The newer stock ecu's have outstanding engine protection stock. Smart.
Stand alone Ecu Companies we Love :
If you have zero experience with EFI mapping I strongly suggest taking a class or at least buy a book from my good friend Ben Strader (EFI 101). I cannot stress that mapping is a lot tougher than some people and companies lead us to believe. Mapping injection can be very fun and rewarding but can also break your heart and bank account.
The benefits from properly mapped EFI are amazing and some of today’s ECU’s have built in safety or engine protection that help keep your expensive hot rod alive. It is important to get your air fuel ratio in the ballpark but absolutely a must to dial in an ignition curve for peak performance. We commonly see an ignition swing of more than 10 degrees depending on the build from bottom to top end.
The bad news about fuel injection:
This is again where Mercury Marine shines. They know their stuff and have a good understanding of mapping using both real world conditions and employ state of the art dyno testing procedures.
At DBR we have tested, raced and optimized Motec, Fuel Tech, EFI Technology, Link, Haltech, Aem, Vipec, Autronic, Mercury, Brucato, SDS and Finally Emtron and Maxx.
After 25 years of testing ecu's on outboards..........I would never use anything but Maxx or Emtron , period. Period.

The bad news about fuel injection:
- It is hard to do without educating yourself or good help from someone who has experience.
- It can be expensive.
- You get what you pay for.
- You can blow up a bunch of stuff learning.
