Possible set up problem with grid on the shift
G,day,
Hoping someone may be able to kick me in the general direction.
Just had a conversation with a friend that has the grid and grid ignition package in his car.
Nova, BBC, TH400, solenoid shift, solenoid relay is triggered by the shift light output.
Is having a problem where when the unit shifts the engine is pulled down 1200 - 1400 rpm as though there is a limiter or something coming on, engine will labour through it and get going again.
Same thing on both shifts, its a low - mid 9 sec car.
I was going to put my msd tester on it and run it up while he has his laptop on the grid and try to simulate a pass and see if anything stands out.
Any idea's out there?
Thanks very much!
Cheers

Is he using the grid to add or pull timing? Only way I could see it causing any issue like that. Otherwise Id say converter is way tight, bad sprag etc

G,day Al,
Yes I believe he is pulling timing to tame it down off the start line.
Thanks very much!
