No knock sensor and tuning
i don't have a knock sensor on my stroker because i have piston slap, (due to weak cylinder walls, short short skirted pistons, and not torque plating while boring and honing).
i am gonna get Rbob's EBL when he starts shipping, but how is this lack of knock sensor going to affect things?
Fast355 already informed me that i can disable it in the .BIN file, but is tuning gonna be harder because of this?
I understand that it may not run to its full potential, but i think once i get bigger injectors, the EBL, and get my VE tables even close to where they need to be, i'll be loving life. anything will be better than a tbichips.com chip.........he thought i would have enough fuel with stock 61# injectors at 14psi. not.

Well.
Do the basic 2-3 degrees pulled from the entire table.
Get the idle stuff tweaked and lower end fuel good.
I would recommend starting and working slow and only work on 1 thing at a time.
Than you will be doing plug cut after plug cut to work on the timing. I can see any other way around it without a knock sensor. Even with a knock sensor you end up doing plug cuts, just to make sure what you actually see agrees with what you are logging.
Try doing some searches in the sticky above and some knock/timing articles written by grumpy and I believe Rbob.
also a few good plug reading articles with pictures out on the internet, cept i dont know any links for them
later
