My understanding is that it does not make changes to the base spark table and each car would be getting the same base table just Iike a factory car. The end user can still make adjustments to that if they are chasing a few more horsepower.
I was curious. So essentially it tunes fueling and idle valve and then the end user is responsible for wot timing changes until they’re happy with the power level.yes the spark advance is changed at the given load at the given rpm in tne spark table. Its the same with the fuel table. thats about as far as I understand it btw. im not a tuner.
he said it would be $1000 not because i had an na vehicle, but because I have the pro m.
I have cost him a lot of money by getting the pro m and not going back for a retune EVERYTIME i change something on my engine.
Honestly anybody who goes back to a tuner over and over again nowadays is a lunatic. With the advances in standalone systems, most people can dial in fuel and timing themselves on a dyno, if not using mph on something like a dragy.
Hard to believe people still do the sct style chips. Been guilty of it myself in the past, but never again.
