We found some info I need to log data to help find some problems. Here is what I have read:
1) Long Term Fuel Trims are doing. what does that mean, where do I look (table), and what is normal considered?
2) See how your 02 sensors are working. what does that mean, where do I look (table), and what is normal considered?
3) See if the 02 sensor is LAZY. what does that mean, where do I look (table), and what is normal considered?
4) LTFT shold be slightly Negative (taking fuel away). what does that mean, where do I look (table), and what is normal considered?
5) They fine tune/control the AFR +- 25%.
I'm familiar and tune my Duramax LBZ and have no experence with LS1/gas.
Thanks for any help. We hope to play today at lunch.
