Title: 80% gasoline + 20% methanol tuning Post by: 4ringpieces on September 24, 2017, 02:17:13 AM Looking to run this constantly so I don't need nothing fancy etc etc.
Am I overthinking it? Mixed lambda/afr would be 1:13.04. Current ltft is -0.8. Injectors currently at 70% duty. Egt is peaking at 900c So would the change of base fuel be as simple as. 1. Setting krkte so lambda trim is near 0? Fuelling is already mostly 0.82 in the map. 2. Adding to the cranking timing and main timing maps via dyno Am I missing anything else? Looking to lower egt without using water/meth injection Title: Re: 80% gasoline + 20% methanol tuning Post by: vwaudiguy on September 24, 2017, 10:22:50 AM Been experimenting with the same. I had a guy go 8 gallons 93 to 3 gallons E (we didn't test ethanol %) and his trims went +5% at part throttle. Car def picked up some tq (no dyno yet). No logs yet because the guy is lazy. :) Still pretty warm here, so won't see cold start effects for quite some time.

Less strain on the smic's, turbo etc etc I'm sure I could pay for a map switchable file creation with a few maps so I can switch between straight gas and mixed gas Title: Re: 80% gasoline + 20% methanol tuning Post by: vwaudiguy on September 24, 2017, 11:02:14 AM I'm not sure map switching would be absolutely necessary if you're just using a small percent of E.
