Okay, using Datamaster to log data, I get a left and right BLM count. My question is, there's only one value to adjust on the VE table, so how do I use those BLM numbers. For example, one data point is 1000RPM, with BLM counts of 135 and 120 left and right, respectively. Should I just take an average of the two numbers or what? Or does the fact that they're so far apart mean that my car is just really screwed up? Thanks for any help.

 

What car do you have and what motor is in it, or better yet what computer is in the car.

I never heard of left or right BLM's

 

It's a 93Z (actually B4C), with the LT1, the ECM is stock, I think it's 1615978 or something close to that. Anyway's I'm getting right and left BLM numbers, as well as right and left Int numbers. And yeah I know it's not a 3rd gen, but as usual you guys know more that the 4th gen guys, on this subject at least.

 

First thing to check is that both of the 02 sensors are working the same.
Then check the injectors to be sure all are working the same.
