The learning curve is long. I will be asking alot of questions. So, if i go with an 8 stack setup, speed density works best. Will it adjust to altitude ? I understand MAF will adjust to altitude. I remember megasquirt was all the rage and now its talked about very much. Why? Let the fight begin so to speak!

The only fueling strategy that compensates for altitude change is a Mass Air Flow (MAF) based strategy. No other strategy is capable of doing this.

When you use a MAF fueling strategy every molecule of air entering the engine must pass through the MAF sensor. Making this happen on an eight stack system is both difficult and ugly. If you intend to run an eight stack system the Speed Density system is by far the better approach to use.

The MegaSquirt drum roll is simply a lot of capability for a very reasonable price, and little niceties that others do not offer like a lifetime warranty — bang for your buck.
