has anyone tuned with alcohol and wat afr should i be looking for wen mixed with pump gas?
Same exact AFR's. Don't be fooled by the stoich of alcohols (from 5 to mid 6's:1) -- your wideband reads the amount of free O2 molecules and converts it into the air/fuel ratio you'll be seeing. Since the amount of mass air the engine is moving is the same, the AFR's will be no different. Just using more fuel volume to achieve the same AFR. That's the difference. B |

Plagiarised, almost literally word for word with a few small additions and deletions, from How to Tune & Modify Engine Management Systems by Jeff Hartman. Don't credit this as your own and do not post this on this forum w/o crediting the author.
B Ahh, I forgot. You came out of the womb knowing this stuff. Oh, that's right. You don't know this stuff. So, you are over here as well, giving your same bad advice? |

Re: Basic Engine Tuning
There is a book called "how to tune and modifiy engine management systems".
It's a very long and boring read but it's worth it. |
