A question for all of those guys that have tuned and/or had their cars tuned on a dyno in the GTA.
When your car was tuned, was it done with a series of “full pulls / ramp runs” or did the tuner actually take the time to load each attainable cell and tune for peak TQ?
(ps - if you were tuned on a dynojet, no need to respond. Only guys that have been on Mustang, DynoDynamics, Dynapacks, Superflow, etc.)
paul runs through the map rpm based trying to hold constant load and do 2-3 base tunes to get the map close
then he smoothes the map and does a fine tune after
i do that too, but maybe holding rpm constant with your dyno would be easier, pauls dyno couldnt do that
i usually smooth the map while i wait for the car to cool down and then once its smooth and the afrs are pretty constant i just adjust blocks by percentage to get afrs i want rather than doing one cell at a time?
what i usually do is before i get to the dyno i go out with a trusted friend and let them drive the car on the street, we dont do any crazy top end pull its mainly for off boost tuning and some mid boost and going into load tuning.
once i got this set the car is set for street driving. once that is done i go to the dyno and i do 2-3 load runs just to give it a one over, after that i do top end pulls to get perfect afr’s and get the timing spot on for max hp with reliability.
word.
this is for street driven daily cars, a race car is a bit different as usually they dont stay below 3500rpm. unless your a diesel.
