timing vs. A/F
Traction is my issue...and I had an electrical issue...
so I stopped at at 12.5 for now....
will be going at it again once I swap everything into the mustang chassis
plugs look ok, but could definitely go a little leaner...
I'm on a #9 and may go to a #10 when I start to bring the timing back in..
I think the end tune up should be similar to what you guys are suggesting, once the OP has a feel for what he is doing and what this car actually needs.
especially if he's on a smaller shot...
do the standard -2* for every 50hp of nitrous to start with and it will be plenty safe.
plugs have a fudge room...sometimes, you add 2 and nothing changes
when if you had used a dyno for spark....you can actually see change in 1*
and typically your best judge of timing is not the plugs.. its your ****Edit*oops, sorry, meant to say MPH****....
when the car stops getting faster, you stop adding timing

Yes, all of those guys will tell you that. They are also very educated tuners who pull the plugs on nearly every pass. I tune the same way. But again, suggesting a novice to make a full afr point change based of a wideband is asking for trouble in my opinion.
Like I said mid-high 11's with the proper timing pulled out will not hurt anything. Of course there is power on the table, but that is not going to hurt parts. Make a pass with the same jets and a little more timing pulled out. Tune off of those plugs.
Small steps and going off of accurate plugs will keep the parts alive.
Ill skip the ABC paragraph on how tuning works. I just think your suggesting big changes to someone who needs to slow down.
Yep.
None here as well. Everyone here has something more to learn.
Some are easier. E85 has a different way to read it than tradtional fuel's as does Alcohol.
