Lean Cruise Settings

[L67PSI]

Did a data log and commanded AFR does change. 18.4:1

the fact you needed to increase tps there to maintain speed when lean cruise came on would say to me that's too much, i'd drop the figure back a bit like VL400 said to no more than 16 and see if its any better.

yep had to double check myself, it's adding spark by default, you can use negative numbers to reduce spark, yep the stock AFR's are really lean, i usually change the targets to hit mid 15's

[L67PSI]

Just made some changes, to target mid to high 15:1 afr. Will data log again and post results.

Thanks

Does this look any better??

[immortality]

Yep.

Did you lower the lean cruise speed threshold? Looks like lean cruise at 58km/h?

[L67PSI]

Yes lowered threshold, to 56km. I think standard was 70km.

With the trip computer I was seeing 6.8-6.9L/100km at 60kph on flat road.
