Flash stall is one of those terms that has different meanings depending on who you speak with. When looking at a converter on a log your flash stall is the point at which the rpm line on your log takes a right hand turnWhen you launch the rpm on the log will go upwards until it begins to bend over towards the right. This point should be near the same rpm as the converter drops back to on the gear change. This is what people should call flash stall.
As you increase power, the point it bends the motor over and the point it drops back to on the gear change may increase.
Good. That's how I understood it. The right hand turn is the engine hitting the stall wall of the T/C for that given engine/torque converter combination. I'll have to look for the relationship between that right hand turn and the rpm after a shift. My datalog rpm line is a little muddied by the nitrous turnoff point at 16 psi, but I'll be taking a closer look. Thanks for the explanation Dusty.
