[QUOTE="decipha, post: 16600606, member: 74327"] if you set your wideband for AFR you have to update it everytime you change fuels. If you set it for Lambda it can never be wrong. The ecu uses lambda it doesnt use AFR. So if you set enrichment fuel to .8 lambda at WOT your commanding .8 lambda. Stoich AFR in the ecu is a global fuel modifier. As long as it matches the actual stoich for the fuel your running then your fueling will be correct so long that your fuel is dialed in properly. this is all covered in my fuel write up best bet is to stop using that archaic method of AFR and upgrade to using lambda and you will be a much more proficient tuner.
