Idle thoughts..

Firstly a clarification of an earlier post on KR. Tordne brought to my attention the fact that I mentioned voltages fluctuations can indicate false knock etc. More correctly this is fluctuations in the recorded KR, which does relate to voltages obviously, but the item to log and observe is the KR in degrees, not a voltage reading. I dont want to edit previous posts except for grammar as I think it shows the learning process more clearly where there is slightly confusing statements, but thought this was worth mentioning anyway.

Ok so after more reading and yesterdays trials I think I now have a good understanding of Throttle Follower and Cracker settings and they actually have nothing to do with idle! They are for transitioning to and from idle.

A lot of the idle tables are inter-related and some effects that appear similar can be down to other tables, here are my current thoughts on 2 off the idle transition tables.

If you have an issue when coasting and going into neutral where rpm rises I think this will be a Cracker issue, you need to reduce the cells where the problem occurs.

The Follower is for leading into and out of throttle transitions so rpm's ramp in and out rather than hammering in and out. (Perhaps to prevent wear on the driveline!?)

The desired airflow (RAF in HPTuners) and IAC Parked Airflow tables are the ones to give you a smooth parked idle from cold to warm.

So if your vehicle bogs off the line, you should look at the Follower values, if it rasies or drops rpms coming to a stop its likely the Cracker tables (during shifts also consider the Follower as it decays airflow on throttle reductions).

If you put too much Follower in you might need to reduce the Cracker accordingly.

Also as per my previous post if you want more off idle throttle response take a look at the Follower tables (The the added airflow and multiplier ones)
