EFI, Alpha-N vs Speed Density fueling Strategies

Take it easy. I am pretty sure that I don't have a learning disorder!

FYI. I am currently running two COPOs. One is running in Alpha-N. The other is running in speed density and closed loop. I believe that both tunes are pretty good. Both cars are extremely consistent. In the past I have had Stock computers, Accell Gen 6 and Gen 7, FAST, and Holley. I have always done my own tuning. I currently run the Holley HP system and find that it is far superior to anything that I have worked with in the past.

The reason for my previous comments was to make the point that Alpha-N with the corrections turned off is an extremely quick way to get a very consistent tune that will show good results.

The bottom line is that if you are going to run speed density, you need to know what you are doing. It takes much longer to define the cells to optimize the tune in all conditions. You corrections need to be spot on or the car will do dumb stuff. We are talking Stock Eliminator here. The MOV is normally very tight.

If it helps any, I drive Robin Lawrence at Holley nuts too!
