I race a 15 second car. Will this come on in the middle of a run? Can I disable this function if nesc. ?

Yes It can come on in the middle of a run. I believe the default setting is 12 seconds. So you need to check it and reset it to like 17-18seconds.

R Hastings,

You can not change the time value on this, 12.5 is the maximum. You would have to simply turn up the RPM value to the max level which will effectively disable this. You mention this is on a 15 second car, just a side note that this ignition is a drag race only ignition and not recommended for street use if this is a street car.

I set the time at 12.5 seconds and the rpms above the maximum the engine sees and it worked perfectly. The car in question is a V/SA stock eliminator car. The reason I chose this ignition was because I run an inline 6 and felt the individual cyl. timing could be benificial.

Glad you got the problem fixed.
