High Idle at lower altitude

[awdturboscott]

Tried my hardest to search for this issue but not having any luck. My DSM was tuned at an altitude about 2k feet higher then where Im at now and now its idling kinda high almost 1300 or so when warmed up. Was going to do the 1g BISS adjustment on vfaq but also wasnt sure if there was an easier way through DSM Link or something maybe or if Im looking in the wrong area to begin with. Im not brand new to DSM's but this is the best condition DSM Ive ever bought and Im too paranoid to do anything with it until I have a solid answer, haha. Thanks for the help everyone.

You can set the idle on the dsmlink. Or you can adjust the biss screw by tuning it in. Keep turning it in till you see the idle drop. Both ways are pretty easy.

Don't adjust your BISS like that, do it properly. The way to adjust your idle in your situation would be set the desired idle in DSMLink then adjust the BISS via the proper method to achieve that idle. You've read the VFAQ so you know how to do it, the only difference is you're shooting for your new desired idle or target idle (terminology) as set in DSMLink instead of the stock 750.

Actually, you set it by getting your ICSposition to roughly a value of 30 by adjusting the BISS which in turn should get your idle close to where you have it set to on Link.

OP:

I have to commend you on actually reading the rules or rather just naturally using proper grammar and spelling. A lot of new people have an issue doing that.

That's actually how I did it on my 2g, but only because I couldn't get the BISS mode working through EvoScan. Either way will work, and after re-reading the VFAQ, the ~30 method is certainly faster and easier. Isn't there a BISS mode in Link that he can run with a click of a mouse, too?

The lower the altitude, the more air.
This is why most cars in high altitude countries' cars are turbo or some kind of forced induction.
Adjust your ICS to 30. That is the stock or average for areas closer to sea level.

I cant thank all you guys enough for the info!!!!! Now I just have to figure out why Im not getting a response from the ECU when I connect DSMLink, .
