Pulling timing for nitrous
Pulling timing for nitrous Like the title says what needs to be done to do this. I am using HP
Tuners. DO I just go to the Spark vs Airflow vs rpm WOt and subtract the desired amount from the table? Also I assume I need to just pull timing from the RPMs where the shot takes place from 3000 - 6200. Also how much timing 2 degrees for every 100 hp ??

You need to pull timing from main spark vs. airflow vs. Rpm high octane and low octane tables. I usually start from 2400 rpm at .68 g/cyl. and pull the desired amount. The rule of thumb is 2* for every 50 hp shot.

The only way to get this right is to data log under use by using 50 shot>monitoring>adjusting, 75 shot>monitoring>adjusting and so on.
Rule of thumb is just what it is a ballpark.
this way you maximise your output and leave no HP on the table.
also 93/94 octane is recommended till ~150 shot then a mix of race gas is necessary.
