Hi,
I'm trying to work out the EOI calculator, I have been told that i need to enter my cam specs into the file which will calculate my EOI table?
Just wondering if someone could assist me in where exactly I enter them, as it's not the "Stock cam specs" tab as there's no tables to modify in there.
Attached is my specs (Dialed in then advertised in first comment)
EOI Calculator - download/file.php?id=9851
Thanks.

Re: EOI calculator
what model do you have, as stock cams for reference can be different, but main changes to notice is more duration, changing the EOI may help cold start, fuel AFR stability and gain a little torque, but it takes some fiddling. On a dyno is best as the gains arn't huge.

I have a VS S2, if you're reffering to car model.The1 wrote:what model do you have, as stock cams for reference can be different, but main changes to notice is more duration, changing the EOI may help cold start, fuel AFR stability and gain a little torque, but it takes some fiddling.

It's running ecotec PCM and loom.
