( Back in November 2010, amid apparent fuel delivery issues, I limped home after this:

At last a chance to get in some runs

Upgraded injectors, made an attempt at tuning, experimented a little....
But DAMN, it was good to be out there again.

Beech Bend Raceway Park, Bowling Green, KY, 09/17/2011, 72 degrees F.

M&H Racemaster 8.5 x 24.5 slicks, 36 lb. injectors, base fuel pressure set at 44. Full exhaust, air filter bypassed. Gas tank full, to eliminate possibility of fuel canister running dry.

Notes: Launching botchalism continues... Added 2 more degrees of timing, but the PC's battery died after the burnout, so could not analyze data.

Had some strange stuff on the cruising scans lately, but made it the 90 miles back home no problem. Except the exhaust seems louder now, may have shook something loose on the launches.
