I was told to look for the b1501 but I can't find it. Mine starts with b1502. My version is V 7.5.5 build 72 Thx for any help.

it's b1502 through b1505. set max RPM to 50, an min rpm to 4500. Set max ETC to -47, and min ETC 300. Go to table C2401 and set diagnostic to "Disable"

Build 72 is quite old - from memory it's November 08. You need to update your software by clicking on Start->All Programs->EFILive->V7.5->Tools->Check for New Updates. this will update you to build 88 which was released this month.

Build 80 and 81 added LBZ calibrations as per our change log, which you'll find on our downloads page, or via this direct link http://www.efilive.com/index.php?option=com_content&view=article&id=126:updatesv755&catid=57:updates&Itemid=134

I suggest you update your software, and then take another look at your file. B1501 wasn't displayed in our software until the last few months - it was added in build 80 or 81. Let us know how you go.

Cheers
Cindy

thx for the response...i completely removed EFI and then reinstalled and now it's there. But now i'm in demo mode and the update is no longer there. Fix one lose another...LOL:D

Put in all of your account info and then plug in the V2 - should alleviate the problem then.

Yes B1501 disables "EGR Performance Testing" and yeah you definitely need build 88

it's b1502 through b1505. set max RPM to 50, an min rpm to 4500. Set max ETC to -47, and min ETC 300. Go to table C2401 and set diagnostic to "Disable"

Which when you have these ^^^^^ tables set the way they are will eliminate the buzzing coming from the EGR when you have the turbo vanes set to ~20% at idle; for the LB7 idle.
