My car takes around 10 seconds of cranking to start. I have the ross-tech cable.

I'm wondering if there is a perfect IQ setting(3.5?)? Also, I need to get the pump timing dialed in. I'm going to work with it some more tomorrow.

When I get it low; it looks good till I switch it to basic, then it drops off the scale and the engine runs choppy till I switch it back.

How do I verify the pump base timing?
