Pretty basic question here:
Doing a little tinkering with the tune on my 2003 Cobra. Stock pulley ratio, headers, exhaust, conical air filter. Noticed the "Stoich AFR" is set to 14.64, which is pure gas. We have E10 93 octane almost exclusively here. Would it make sense to change the Stoich AFR value to 14.08 to reflect E10? If so, is there anything else I should also change to reflect E10's higher fuel flow requirement?
Thanks in advance.
