My BLMs are high, all the time. Neither side goes below like 137, ever. They are at or close to 160 at idle.

Simple way to lower them with LT1 edit?

 

Use the map table or lower your injector constant if it's lean through the whole band.

 

I believe adjusting the MAF tables is the easiest/best way. Playing with injector constants can cause other problems.

 

Sorry i've been in speed density land for awhile, sorry maf tables.

Constants can be used to effect global changes, it's often the best way to correct for aftermarket injectors that never seem to flow what they should.

You will also need to modify your contants if your fuel psi is above stock..

So your wrong contants play a base role in tuning.

 

actually the inj. constants are the best way to do it, the MAF is the easiest... if the PCM is adding fuel, then the fuel system cant supply enough...

 

that didn't make sense... if the PCM is adding fuel then the fuel system can't supply enough fuel think you might wanna re-think that

if the BLMS are high then the PCM is ADDING FUEL cause the car is running LEAN...

your trying to change the setting's in the PCM but have you checked to see if you have any exhaust leaks yet? if you have any then they will suck in air and then your o2 sensors will think that the car is running LEAN when it really isn't and then that will cause HIGH BLM reading's, which is probably them problem your having...

 

what i am saying is there is more air coming in leaning out the A/F, and the fuel system i.e. the injector constant isn't high enough..if you raise the constant or get bigger injectors it will lower your BLM's due to the higher fuel flow through the injectors..

 

Exhaust leaks at the Y-pipe may be the problem, I'll fix that first.

Thanks for the replies.
