Question for you guys. Just got my tune back from W4M. I need to add some more fuel. What tables in EFI Live need to be adjusted. I'm told that im running lean. Jesse told me that he tuned my truck for the Stock 6.0 injectors. However I'm using the 4.8L injectors. So im sure i need to add some more fuel. I'm new to EFI Live so im not sure what to change.

 

Change your injector flow rate table for the correct injectors first, then check AFR and go from there.

 

Are they stock 99 injectors, or later model one's? In 99 all the injectors where 21.8lbs/hr. 2000+ are all 25.2 lbs/hr injectors.

Table B4001 should have 21.8 in all the cells if they are the stock injectors for your truck, from the stock tunes i looked at.

 

Do i need to change anything else to get more fuel? Because Jesse from Wait4Me told me I'm running lean.

 

I'm showing in that table 3.1 all the way down... but my table variables are Injector Flow Rate (Grams/Second), and Manifold Vacuum KPa.
Am i supposed to change all those to 21.8?

 

If your set to Grams/sec, then they should all be set to 2.7 That's why it's lean, it thinks it has bigger injectors then it does, so it's not opening them as long. Try that and see what it does.

 

Allright, just tried that, and im still gettin KR all over the place. If i go anything over 25% throttle, it jumps right to 8.0KR and starts retarding timing. Here is my tune file if anyone can take a look at it for me.

 

Can you post a log?

 

i posted one in my previous reply if you didnt see it.

 

Not your tune, a log from the scanner of your truck running with the KR and O2's, so I can see where (if) it's lean and the KR is coming on at and reference it to the tune. Everything I see in the tune looks ok.
