I've been working my way thru the EFI firmwares with my DBW 07 Exige S -- I have to agree the latest firmware is even more daily driver friendly and seems to have much improved Accel.

It's sad to see folks dropping DBW and going cable -- how often do you hear DBW folks complaining about a stuck throttle cable? Or an idle screw that backed out? I don't think DBW is about smog, it's just a better and more modern system. I think DBW got a bad rap because of other issues -- I know I strayed thinking the Lotus DBW system was bad but that appears not to be the case (it was 3rd party install/tuning issues, not the DBW unit).

Kris at DRS (aka is DRS) spent over 6 hours one day recently working thru daily driver issues with me (he was sitting in my Lotus while I drove) and explained to me what to look for and how to correct/adjust to meet my pretty high standards of driveability. I couldn't imagine anyone else doing that for a customer. So Kris is available, but you just have to arrange it and hope his schedule permits it (he has to earn a living so I'm pretty sure he doesn't sit around waiting for phone calls to answer questions).

The other benefits of DBW is that you really can control the throttle curve and make it work to one's driving style. You can change the throttle degree angles at various set points to meet track needs vs. street needs. Or for finer small throttle changes have more setpoints in a narrower throttle degree range say from 9.5 - 30 degree and make the setpoint wider for WOT operations -- or visa-versa.

Also, the Accel features seem to work a little better on DBW cars.

If you have a Turbo application and the car is a little too on/off with boost (mega boost or a weak wastegate), you can create finer resolutions (setpoints) around the throttle degree range where the turbo gets a little twitchy.

Lots of options with EFI and that's what I like. EFI might initially be a little pricey, but based on the frequency of my changes to the car, EFI is really the long term cost effective solution for me.
