Delco Jeep

[Dylan]

That's good news. My latest bin and the earlier one's had charge temp mods and coolant contribution mods.
Hopefully I'll get a look at the log tonight. Good to see you're having a win now.

[Dylan]

Have a look and post up another log. Only lean areas is idle the rest I quite rich now.

How do I adjust the actual AFR closer to the Target AFR when the engine is still in the warm up phase? I I've got a few areas that are bit lean.

[Dylan]

The warm up phase would be best done with charge temp changes. Once warm stick with VE.

Did you look into calibrating your wideband?
Or were the 0 5 volt settings right?

[v6bucket]

The wideband is correct.

I've had an issue with the Torque convertor not staying locked in, thinking that it was something to do with the CEL on, I changed back to Jeep configuration.
The 1st log is with the the delco recording with only sensors hooked up, between 5 -5.13 I made a wot run, well the Jeep certainly puts some juice in, afr ws into the 10s.
The 2nd log is the delco running the spark & fuel, with the "Charge Temp" tables from Dylan's last bin, different car, well Dylan, I think your onto something. The afr is still a bit ugly, but I imagine that it should improve with the narrow band hooked to the delco.

I will look tonight can't wait. An afr that rich will kill iff power for sure.
You want to get the fueling pretty close as the BLM's onky adjust so much.
And are lost whenever battery is disconnected.

[Dylan]

That bin you have there, is that the bin you logged?

[Dylan]

The 8026 log doesn't have any data, well for me anyway. Maybe someone else has more luck or upload it again?
