There's no way to change the target A/F in closed loop to anything other than 14.7, at least not in a global setting. You could scale the MAF table by a certain percentage or something like that, but that's slightly different.

This is correct, but you can change that behavior if you want to.

You can use this program to make it always lock the BLMs to 128 regardless of what the pre-WOT value was.

Re: Tunning for crusing with tunnercats

I have seen that program and it is interesting. It makes no changes to viewable tunercat file but changes the assembly instructions in three locations. I believe it is forcing program to believe the long terms were 128.

Do you know a good source for disassembled code? I have disassembler etc and have torn into some code but wanted a start.

I have seen many site but seems most have inactive links like http://www.lt1edit.com/pipermail/lt1...06/012252.html

I would appreciate any help

Thanks
