Well apartenly they were "tuning it" timing was 32...No info on idle or cruise was provided
A I have so often commented... they MAY have simply 'tuned ' to the best of what is currently on the car.
If u want to dial the engine in, u will need a data logger with at least rpms and 02 sensors
Dial in is setting the power valves, butterflies, jets, cent curve, VA curve and vaccuum, to the best potential of the engine in that car.
I use the older innovate LM1 with rpms, O2, knock, IMAP and TPI sensors... car computers are not required to run these thru a data logger.
The cost of a data logger is cheaper than the dyno time, and u will find the occasional
dyno guy will also use a data logger to dial the engine tuning specs in.
I say "occasional" because the number of so called trained dyno technicians who actually know what the hell they are doing when dialing in are few and far between.
And your dyno guy should have supplied far more info than that...even for the little useless bit hes done.
There are many threads going back quite a while on how to dial in, ball park starting specs, how to set secondaries etc how to establish idle , total and all in timing... how to change the degs in a pionts or HEI dizzie, how to change the vaccuum range a VA works in .. and the degs in it.
Not only that but very long threads over several weeks talking guys thru step by step and explain what they are doing and why each step.
READ and learn.. u may find many of those common old school methods are now just myths and old wives tales that will not go way, inspite of affordable 21 century tuning tools available to the home workshops these days.
