- 2003.5 mazda speed protege #516
Hi everyone! I'm in need of desperate help. I was tuning my mazdaspeed protege via split second afr calibrator yesterday. I keep running into the same problems. Problem #1: when I start my car when it is cold it runs extremely lean.. as in 18:1 +. Once it is running for a few mins it goes up to my desired range between 14.3:1 and 15.0:1. Problem #2: I tried adjusting the "over pressure" to 1.1 as other msp owners have done. When I do that, the car will run WAY to rich. As in 8:1. What is my problem? Right now my over pressure setting is at 9.75 which is how the settings were when I puchased the car. As I'm typing I noticed under system settings the display mode was set at vacuum/pressure. Would that be affecting the system? I believe it should be gauge pressure if I am correct. Please help! I'm sick of this headach. Thanks for looking!
Edit: all of the afr readings were at idle.
