tps evaluating for ii issues

[SportsterDoc]

Does this mean that Americans are more honest as Honda sees no need to have the HISS on their bikes in the USA ?

Or maybe the HISS is replaced by a .357?

Drifting back to the subject, once the tests suggested by Max are complete, it would be good to have TPS voltage reads, per Max's video, when the idle is low.

This link is from post one of Max's thread TPS evaluation for ii issues:

More info from Max in post 632 (page 64) of CB1100 idle speed instability problems.

Meanwhile I am beginning to wonder if high idle is an IACV issue (IACV or IACV connection or crud in the IACV port) and low idle is a TPS issue (TPS or TPS connection), with the problem possibly increased by a vacuum leak.
However, that does not seem to explain vacillation between low idle and high idle...just thinking out loud.

Perhaps the ECM updated program, available outside the USA, may have some compensatory algorithms to deal with such issues?

Meanwhile, it seems that Max's focus on the TPS for low idle is an appropriate direction.
