I started up datamaster just to see how things were doing. At idle in closed loop, my long term BLMs were at 158/160. What is going on??? I have a log. Can someone help. I went for a long cruise and logged a bunch. Please help

 

Anyone????? Need help badly!!!!

 

need to know what youve done to the car. like what mods, what size cam. what did you do to the car right before it started this.

these are things that will help help you.

4 inch exhaust (recently installed)

I am about to check for any exhaust leaks tommorrow.

 

I am very confused, I checked the car for exhuast leaks. Cant see any sign of any leaks. What would make the car go so lean on idle. I know prior to putting the 4 inch exhaust on the blms were close to 128/134. Any suggestions. How can I add more fuel in the idle cell. If i do add more fuel for cell 16, do I have to spend time on the dyno for wot tuning?

So many questions, such little time.

what LSA is that cam on? the overlap will dump extra oxygen through the exhaust causing the sensors to read lean while the engine is prolly way too rich by the time it compensates with LTFT, remember that the fuel thats also thrown out the exhaust isn't picked up by the sensors since they only read oxygen, stock cams don't do this, so you have to work around this, what do you read while driving around? Prolly fine right?

I can send you a datamaster dump if you can help me. I am at a loss. I am in the middle of doing the mod to my bbk 58 mm throttle body, just to see what that does to the split. Let me know.

yes that would be great. send datamaster to vincentbergeron@yahoo.com

 

Sent you a file that had idle to a cruise around town, then idle again. Let me know what you think.

Did you get a chance to look at the files I sent you? Let me know.
