you need something to richen it up a bit....the increased heat from lack of fuel will cause the piston to expand more wearing the rings out quicker...increased heat also will wear the valves out quicker....bla bla bla you get where im going with this....

 

thats why I would want to know if I can use a colder plug for now because im saving up for a F/ic

 

colder or hotter plug doesnt effect the amount of fuel going in...need a way to control the ecu...for someone like yourself the apexi afc would do the trick cheaply and easily

 

How does timing play into this; the way I understand is that when you add a lot of fuel, you can subtract a bit of timing. But when subtracting fuel, it is not good to add timing... or is it?

 

timing does not change the a/f ratio....when tuning get your a/f ratio set and then adjust timing....only way to set timing correctly is on a dyno...
the term to remember here is MBT or minimum best timing....your want the least amount of timing that creates max power...

 

So I tried the 13.1 , 13.2 and I think its a little rich for me,right know as I tested so far is runnning 13.5 from 3,000 to 5,500 then after that 13.2 feels really good and gives me a good amount of torque,as for half throttle I have it running 14.3 wich is giving me better acceleration with less throttle.

 

My N/A special is 12.9, Which i found out by messing around with the F/ic = ) , Big butt laod more power as for butt dyno

 

How do you like the FIC I'm the fit?? Heard pretty good things about it on SRT Turbo Powered 1st gen DOHC Neons but didn't know for the fit!?!? What Part number also?

Marko!

 

I can tell you that its been the best upgrade for my car after all the mods, The part number is 30-1910 boomslang makes a harness so you dont have to cut the wires but its $200 I ended up cutting the wires.

Holy crap?

 

Tuning to AFR

 

My 2008 GD3 Sport has had a liberal amount of heat soaking tape applied to both the inside of my header cover and to the outside of my HKS air intake. My idle A/F is 15.1. when I'm driving it never goes below 14.1 13.8 is a hair on the rich side.
