Controlling lambse on decel

[PaulC-turbo5.0]

Did you see the load drop to below .16? Did you try increasing to a higher load?

Yes, I did definitely se load drop below .16. I didn't try changing it to a higher load. Am I right to expect the CL/OL indicator switch to open loop when FN338 is functioning as expected?

Yea the indicator will switch.

I would try increasing the load a bit next time to see if it will go into OL.

I'll finish sorting through my electrical gremlins before having another go at this. Thanks!

Gremlins gone. I can now see it dropping into OL on decel at the desired load value. I might try raising FN338 a little, just to experiment. Thanks again for the guidance on this!

Nice! What was the culprit?

[canuck1]

Looks like maybe a combination of things, mostly a vacuum connection to fuel regulator that had unknowingly pulled off. Everything looked visually right, but when i tugged on hose, i could see it wasn't connected to manifold barb fitting. Small vacuum leak and an operator who continued to make changes to MAF values made things slowly worse, until it no longer supplied fuel as demanded. Yes, I'm embarrassed, but at least I'm willing to admit I screwed up! Seems good now.

When I get home from brief vacay, I'll try a higher value for FN338.
