Hello,

I just bought a 2003 z06 with a mild cam and the car idles at around 900 rpm which I believe is making it idle smoother than I would like. Is there a way I can reduce the idle speed or mess with idle spark tables without having to spend big bucks since the car is already tuned? I am just wondering if there is a possibility to make it lope more easily, otherwise, I will be happy with the way it is. The only info I have relating to the cam is that it pulls 18 hg in of vacuum at idle which makes me believe it is a pretty mild cam.

Thanks,

AJ

Pretty simple to just open the tune file and reduce target RPM. since you just bought the car, you'll most likely need to pay a tuner or buy a tuning program.

less rpm, less timing, less fuel (or else the less timing wont burn it all).

it'll sound lumpier.

there's this assinine thing thats popular lately called "ghost cam" i guess you could look up, and figure out what those people are doing. its a way to make idle sound like you're cammed.

i'd rather bleed out than do that to one of my cars, but to each their own.

To make it lopier at idle witout a cam change you can take out some timing in the
base spark in gear and in P/N--this will affect idle only You can also play with the desired idle--If an A4 it can be trickier but with a m6 no so diificult With aftermarker cams most add 2-4* at base idle to get a smoother idle so simply remove it out or remove 2-4 * only in the idle RPM range and the fuel use areas at idle ( .06-.24 grms)
