2019 ctr flex fuel

Post by redlinectr »

Went out and did two wot logs and the afr's jump up and down the entire pull. Is this normal or is there someway I can get these smoothed out? Attaching the two logs to have someone take a look.

Switch off the high pressure fuel pump duty limit. Reduce your boost by ethanol limit values.

Fuel pump limit was not enabled. So is there really any point in running this flex fuel tune if I have to turn the boost down to stock levels then?

If you look at the logs when the fuel pump duty is at 88% the afr is 12.1 and seems fine, when the afr's dip way to 11.6 which seems rich then the fuel pump duty goes back up and its like there chasing each other. I just find it weird that the afr's are changing one whole point even towards redline when the boost drops off there fuel pump is in the 70's but still 12.6 on the afr when there is plenty of fuel there?
