Naf, thanks for that explanation... but I was asking nick123 that question to see if he has any understanding of what he's doing or if he's just blindly following the procedure. Yeah, he probably doesn't need to do this with a mild cam but it's his choice.
[QUOTE=nick123;252663]the closer I get to 550rpm using B1652 to reduce idle speed the rougher is seems to idle.
I zeroed 1845 and 1843
63 g/s in b1829
First start after idle trim reset ....runaway idle to 1000rpm
Used 1852 to bring idle down started with 1.1 went down to .75 still 630rpm
Ran best at .8 702rpm
Ok so I kept going
.6 in B1652 680 rpm
.5 and it hits target rpm right away dosen't slowly idle down while cutting timing... timing barely spiking above commanded
.4 sputters adds allot of timing 32 deg
.53 starts just over commanded rpm slowly idles down while cutting some timing then adds timing back after reaching 550rpm
I drive around like this for a day added some timing 25 deg adds some rasp...idles around nice in parking lots and low speed cornering. Before with stock settings it would hang in 3rd and do a firm 3-2 downshift at about 25 to 30 kmhr super annoying...
So the problem now is cold starting it at .53
.53 sputters
.6 a bit better but wont stay running
.7 same here
.8 stays running but throws code (cold start enrichment)
.9 throws code
1.0 no code
This was all done cold and with B1829 maxed out and 1843 and 1845 zeroed.
At 1.0 in B 1852 it idles at about 750 and pushing 8 to 9 per second
I add the 1843 back and change 1845 increasing g/s in negative idle areas up to 0 at 0 and decrease g/s in positive idle areas.
