+The AEM AFR gauge only reads AFR/Lambda, but all the Cosworth fuelling documentation works on setting CO% figures. This table is a conversion between the two, as well as the required AFR/Lambda readings for the recommended base fuelling setup for the MSD Evo chips.
+**With** Lambda/closed loop control in place, the Cosworth figures as supplied by Motorsport Developments for their 320BHP Evo chip engine map state the following:
+   * 1.5% CO
+   * //corresponding to// 13.94 AFR/Lambda
+**Without** Lambda/closed loop control in place, the Cosworth figures as supplied by Motorsport Developments for their 320BHP Evo chip engine map state the following:
+   * 2.5% - 2.7% CO
+   * //corresponding to// 13.56 - 13.49 AFR/Lambda
