300c rpm hangup

[benjohns]

So im driving doing 100kph and when i remove my foot rpm drops down to 2k and stays there car says doing about 80kph for a long time

Any way of making the rpm drop down to about 1k

Can you post the stock tune so we can see what changes you have made?

Return all the engine Torque Management> Engine & General tables back to stock. These tables have a great effect on idle control & idle hunting/high start up idle speed.

all sorted the minimum target is now 704 rpm

and took .2 out of the throttle between 900 rpm and 1650rpm

stock 300c have a rolling high idle

In the first tune you posted at 20mph it only adds 180rpm, and at 6mph it was only a 20rpm adder. As for min set point in drive, it was 696rpm. I don't think these would have contributed much to a hanging idle. Did you zero out the rolling idle adder?

BTW I see your max idle max setting is maxxed out? On other tunes it is usually 1300 for P/N and 1000 for Drive. If this truly controls max idle why would one want to max it out?
