are we happy with the current combination of rx apis available?

@rusefillc - he mentioned this engine already has a lumpy cam that causes some significant speed variation at idle.  It may be worth updating engine phase at every primary...

So any variation in engine speed between the sync point and VVT tooth show up as jitter in the resolved VVT position. With a lumpy cam, you get a lot...

obligatory X-Y problem question: what are users expecting to change at runtime that will actually change the fueling such that it needs a full separate VE table?

But why would the *VE MAP* be different? What does he actually want to change? There should be no change to the VE map based on what the driver wants....

I disagree. Your target AFR table should be shaped so that you're in an efficient regime while cruising, and a best-torque regime while floored. Ignition is even easier: everywhere should...

We're conflating two different problems/features here. 1. Switchable/blendable maps 2. Per-cylinder trim maps

How many of those cannot be done in lua? 1. Limp mode: subtract 0.2 from target lambda, subtract 5-10 degrees from timing 2. See 1 3. See 1, but do...

I can have a look at this to try and reproduce with the provided info, I think it's enough to at least try.

I think this is *probably* fixed. We saw a few people with similar issues, and updating to latest seemed to fix the issue.
