Build Stretched 1-Ton FJ40

[Mike Shull]

This is quite surprising, but note that this was on the previous version of my tune (V49). I'm thinking that this thing is way too lean as it is adding a massive amount of fuel in the LT trim. Does this seem right?

This log file was normal city driving.

The ST is leaning the mixture (same log):

I'd like to see a wideband reading, if you are playing with spark a ton i'd bet you need to adjust fuel trims. You don't get a ton of info from factory narrow band o2s on overall trim. Almost ever tuner I've worked with wants a wideband before anything happens.
