Sequential injection? Reflashable ecm? For TPI? Check here!
www.weswoodperformance.com located in Florida, has recently begun R&D on their new Digispark system. It offers sequential injection, reprogrammable prom, increased hp/torque/mpg. Theyve tested the system on a few corvettes, and are ramped to begin testing on F-bodies. The kit is an LTX style ecm for quick reprograms, a modified engine harness, modified MAF, and modified distributor. Ive met the owner, Wes, and they are prepared to begin testing. Shoot them tons of emails and perhaps itll get them moving a bit faster =)

Looks nice but I would question why they developed it for a serial only connection, serial ports are not very common on modern laptops, USB would have been a better idea.

Incorporate wideband O2 capablity like an Innovative LC-1. Make it expandable to use distributorless multi coil ignition systems. Incorporate boost control solenoid acctuation. How are they determining the #1 cylinder intake stroke without a cam sensor? That's critical to getting SEFI to work correctly.
Sounds like a cool project, but in reality SEFI is only slightly more efficient than batch fire EFI. It uses less fuel, so better MPG & BSFC numbers. Peak power is the same. You can tune cylinder to cylinder fuel, which is cool, and offers a lot for race guys. For the street it's doubtful you'd notice the difference.
