COS3 running rich

[southern]

So I upgraded to cos3 and I cant get my truck to lean out. It idles around 11.5-12.5 and cruises around 12-13.5. I have my VE at cruise around .98-1.02 ben. Also my logs show 90-102 kpa at around 35% tps, I was thinking that the KPA should increase with throttle so that 95-100 should be full throttle. Right? Here is a copy of my tune it is by far perfect.

Vehicle details and a log would help alot.

Just at a quick glance....you still have DFCO enabled which may skew your autoVE data and your TPS isn't showing less than about 17%?

[southern]

I'll try disabling DFCO, as far as TPS it's usually around 12 to 14.

[hquick]

Unless your vehicle is different to everyone elses....I thought your TPS should read 0% at idle. (ie....foot off the pedal).

[southern]

since it has ETC it idles around 12 to 14 foot off the pedal. Only the the cable TB's ildles 0.

Ahh...thanks for that. I never knew that.

[BlackGMC]

can you post up some logs? Also you Desired Airflow table is pretty high, mine is about half of that..

[southern]

I will try to get another log tomorrow. As far at Desired Airflow are you talking about B4307? If so I am about to raise it back up cause it will not idle good especially when you come to a stop. I have a new WB sensor that will be here tomorrow so I am going to try it out and see if I cant get it to cruise above 12.5:1.

At our Sea Level (867') in Texas we can see 90 to 95 Kpa is it .
