how much knock do you guys tune for and say its safe? i know that 0 is the target. but do you tune untill you get to like 2 counts then back off the timing?

also does any one know any helpful ECUFlash tuning websites?

 

Anything under 3 is pretty normal, and happens on occasion, anything over 3 but under 10 or so, isn't anything to be hugely alarmed at, but it will affect your tune. Ultimately you want to keep those counts at zero if at all possible. Just have to keep them as low as possible.

Check the forums, they have TONS of useful info..

 

Depends on how aggressive your a/f and timing maps are.

 

ok this is a screen shot of my stock ECU on top and one that some one made for a evo(not made for mine) and i guess its a good starting point

i will be running off of 91 gas. how does this look? i dont have a WB AFR, so i wansn't going to go as lean but maybe lean mine out by like 2-3 tents in the upper RPM's cus my last log i was at 101% IDC's

 

That modified fuel map looks horrid. Very lumpy, and leaner than I like in the midrange.

Original one probably just needs leaning out in the 5000+ range. Do it with a wideband or leave it stock.

 

ok thanks ill leave it stock untill i get a wb or a tune

 

Er, here? Glad to have you aboard! Get that wideband going and take it easy.

I would not run that fuel map without a wideband. Actually I wouldn't run that fuel map with a wideband either.
