I tried this with the MB100 fitted with an MPGuino, and it didn't work.

Today I tried it with UFI and SGII and got simular results to those posted. Unfortunately, the technique only works when rolling. Although UFI has stop-start, the engine off means no A/C. It would have been awesome if I could sit stationary and keep the A/C on with a 70% fuel saving.

Either way, it's a very distracting way to drive, paying attention to SG and the revs at the same time while trying to blip the throttle the correct amount. For DBW throttles it could easily be automated though.

I will point out that UFI doesn't have a hot wire AFM (or a throttle plate) so SG doesn't exactly produce very meaningful results. This really needs to be verified via MPGuino, then automated via Arduino
