I got the truck running with a regular 6.0 tune but when i upgraded to a COS03 it wont start. Also when i did have it running it runs like crap. I have not done a case relearn because i couldnt get it to work when i tried it. Any help would be great. Thanks

 

Here is my tune. One is the COS03 and the other is a 02 OS. Thanks guys.

 

Fix the out of range parameters first. Boost VE, Boost timing, and most important the IAT VE multiplier. B3647 is important too, I'm not actually sure why yours is showing the units in lambda. It should be an EQ ratio of 1 or 14.63 AFR.

 

I sent you an email with some corrections to your tune. You had some out of roange problems and your Command AFR table is setup for AFR values and you put in EQ values...

 

Select properties under Edit and change the units to AFR. Then close and re-open the tune. It shows me a commanded AFR of 1, it should be 14.63.

 

The units are in AFR but he put EQ values in it...

 

your not boosted are you? are you wanting to disable maf and o2s..

 

Im not boosted. Duh. I just looked at my tune and i was in such a rush that i didnt change my values. Thanks for the help. Im sure i will need more.

 

then you can raise your timing quite a bit

 

I plan on doing that but i cant get the thing to idle. What do i have to do to tune for my cam? BlackGMC fixed a few things up that i did wrong. Im a noobie to this hole tuning thing.
