split block learn multipliers

Just as many have warned, my cam and head swap, coupled with headers and a 52mm tb, has caused my blm's to split. Left bank (I assume driver's side?) averages 145, right bank averages 119.

I know there is a programming fix for this, provided that everything else is o.k. (no leaks, etc.) anyone know what it is?

Thanks.

You should try to adjust your blms a bit with the stop screw on the throttle body and watching your Idle air counts.
The program fix is called "BLM LOCKER" depending if your car is OBDI or II you can get it for free.

OBDI version availiable at Christian Millard's site. www.carprogrammer.com

Thanks for your help here.

I haven't yet. I take it this is the procedure you speak of:

Does this only work at WOT (to avoid the extra rich spray caused by blm's over 128) or can it be used at other rpm ranges as well?

The BLM LOCKER does only work in WOT, as defined by the WOT table. (tps vrs rpm).

That is the correct link for the split BLM "medication". It did work for me at idle. I was not able to completely match both sides, but I was able to get them both close together and both smaller than 128.
If you have BLM's larger than 128 in only certain cells (my case) you can correct it by either editing the maf calibration table or altering the injector constant or a combination of both.
