This is how a lot of the GM v8's with HP Tuners did lean cruise before HPT unlocked the lean cruise part of the pcm. It's discused in this thread, http://www.hptuners.com/forum/showthread.php?t=4929

I dont remember who brought up the wanting to cruise at leaner than stoich.


A member on a local forums www.240sxone.com told me about this what do you guys make of it?

most of us running standalones with a wideband are running leaner than 14.7.

I think I tune for 15.5 in cruise. Some go as lean as 16:1.

whats your spark timing you are hitting in cruise cells though?

I never had a problem with crusing air fuels but might help some i guess i dont like going crazy with the complex shit just what i need to make it run, make power, and safe.
