Emission Reduction thresholds are during a cold start. We currently do not have the threshold tables on the S197's, but it could be coming up with our first gen coyote strategy updates.
You can zero the Emission Reduction MP and not have to worry about it. Or use MP 10 and the angles associated would be advanceing the intake between -30 and 0 degrees.
Optimal Stability is used mainly during decel by advancing the intake between -30 to 0 degrees. This creates a type of resistance or load against the motor to slow it down. Since it's used on decel, Optimal Stablilty will occur during most manual car's shift, cruising and WOT. Stock Op Stab table also uses MP 10. The order is 0, 10, 0, 0, 0. With small changes to cam angles or adjusting the Distance Tables. A high RPM shift can be perfected, instead of the intake advance 30 degrees and the exhaust taking resting position. Adding in MP 7, order now 0, 10, 7, 0, 0. None of us have the EVC at zero at all in our OP Angles, but it is still needed for full decel. During a high RPM shift, you can have IVO -30, EVC 15 or using a different mapped point in place of 7, you can have IVO -22, EVC 12. I mean really, which ever combinations you can come up with
So gap rider, return your opstab and emission reduction to mapped points to stock or zero out emission reduction. They're really calling for some strange angles during a shift. What mods do you have done too btw?
Your Intake Cam Advance Limit - in the 1000 RPM and 1200 RPM, between 70* and 220* F, set those angles to -40*. In the 1500 and 2500 RPM columns between 70 and 250*, set those set those cells to -50.
Below that table, Intake Cam Retard Phasing Limit
set 1000+RPM and 70*+ all to 40*.. 16 cells all to 40*
Here's a little more you can change or anyone can change to get a better running first gen coyote.
