Turbo LSJ Tuning with Cortex Boost Controller

[ncgoblin]

Hey Guys,

I am starting to dabble into tuning via goat roap garage channel and up to this point I have sent my data over to ZZP which has done a great job. The issue is I have a long bit until my cortex boost controller is dialed in properly so I figured why not understand the MAF tuning while I have all the equipment.

My AFR Gauge is a AEM 3000 series. I am stuck on one area right now which is an important step. In the video its mentioned to use the built-in equivalence ratio commanded which is not an option on the 05 ECU. I followed the similar math to calculate eq ratio error but utilizing Air Fuel Ratio Commanded (low) instead. This data will not let me transform to Lambda like I did with my AEM - AFR so when AFR is 1.0 Commanded is 14.7. Will this mess up my calculation? I am curious what you all have created for a math parameter to calculate eq ratio error to apply to a graph.

Hope this makes sense I am just starting out.
Thanks

My EQ error ratio was just the percentage of difference between the commanded air fuel ratio vs the actual air fuel ratio. Doesn't matter if you use lambda or not, as long as your math gives you the percentage of error.
