Cruise Control Effect

[eboggs_jkvl]

Getting closer to a good tune but I'm stumped for now. I took a 2001 LS6 tune and loaded it into my car. The hunting for idle in open loop seems to be under control but I have the Cruise Control effect now as I drive. THe RPMs stay at 2K until the car is almost to a halt, then the RPMs idle down properly.


So, any suggestions?


I was going to tag the .tun file on here but it's not a valid file for downloading as an attachment. Fudge... Hm.....

Sounds like you have to much air via B4307 Dsired Airflow table

[eboggs_jkvl]

Sure doesn't seem like too much to me? Should it go lower than that?

[Dirk Diggler]

Is your TB drilled, bigger than stock or ported?

[eboggs_jkvl]

Stock TB, not drilled, no porting. My "Complete SIG" shows my modifications. The only intake "mod" is the Weiand polished intake manifold.

Check {B4312}, is that the speed when your idle returns to normal?
If so then maybe your throttle cracker table is too high.
Just to test if it is the throttle cracker, halve the entire table - did it reduce your idle speed while the vehicle is moving?
If so, keep adjusting that table until it is correct.

It seems pretty low now.

Move your IAC effective area down on the table until it stops. I had to go down 9 places on mine despite everyone else only having to go 6.

[eboggs_jkvl]

OK, "down". IACnow is current. Which way "down". Like IACnew or IACnew2

I believe is he refering to IACnew.
