Basic Engine Tuning
#41
new to the EMS world, so i got a lot of questions. TIA for the patience.
so, tuning the engine is kind of like a gamble, since we take fuel away until we get detonation or knocking?
i am not sure, but does the haltech/microtech/PFC have a knock sensor? if not, then the basic setup to tune your 7 is
EMS + wideband + datalogging + knock sensor. am i right?
i am planning on getting the LT12 and do the tuning. but it's such a dangeroud mission....

if you take it easy and do it in steps, its not a gamble. leaning out untill detonation isnt always good, when i tune(carbs for now) i tune for power, not nessasarily a/f ratios. the butt dyno is a wonderfull thing!

I learned most if not all of my tuning methods from Chris(Dragon) and IGY.
Basically, I tune with a wideband 02 sensor(techedge 1.5) I use the datalogit for the PFC to record my a/f's for a certain run and go from there.
I don't even bother to look at the knock sensor anymore since it seems so sensitive at times that it picks up little things that "could" be knock, but turn out to be road noise. I've seen my car knock to 100 below boost in the 4000 rpm range...if my knock meter is correct, I'd certainly be knocking...but how do you know at 12 a/f below boost? Practically impossible if you ask me....especially considering that I run a good a/f for driving.
I'm using IGY's timing map right now and used my datalogit/Techedge wide band to tune my top end. Currently running 11.00~11.20 a/f at .8 kilos boost.
