Unfortunately we can't learn that from a book.

lol, I figured that would be the answer, So just get close enough to what I think it should be based on whats around it, drive around, make sure its OK, and let the the log analysis do the rest of the work?

I worked on a 15psi fuel map this morning but before I just go ahead and burn it in is there anything I should do with the spark map? Here is what mine looks like.

Seriously, why does everybody drop out ~10 degrees of timing as soon as they go into boost? That map's probably "safe" in a sense that it won't knock, but it's not optimal by any means. Timing values should climb after peak torque to peak power. Yours don't. IE-at 183 kPa if you can run 13* at 5200, you can run more than that at 6300 and even more at 7K.

i do, but hell I'm 10° more advanced than that map even at the 100kPa row...
I drop around 7° of timing within the first 4psi. then another 7° by 4K where i see 14psi.

Yeah, I know its not optimal. Im more concerned with it being safe for higher boost until I get to a dyno.

I would a few rows around idle, then go on the pattern. Say 20, 25, 30, 34, 40, 60, 80, etc. Do some research on scaling them. I keep all my maps scaled the same (cept VE cause it's 16x16) so that it's easy to read them and they're all similar. And I keep the number simple too. And when looking at a datalog, if I'm smack in THAT cell in VE, I was in that cell in my other tables as well.
Meh, scratch that. Here's how I scalled my 12x12 tables. Copy me.

Use your brain. Do what I did. Find every timing map you can on this site. Took me like 1 hour of searching and I had printed 20 different maps and labeled them with who's they were. Then I look at them and figure out which ones are fair, decent, ridiculous, etc. Then look at the ones that are close to your setup. That one I posted is running in my car and does well. But like I said, I have not ran 12 PSI at 2500 RPMs because my turbo doesn't spool that fast. So those cells are not necessarily "tuned", though they should be safe. If anything, pull two degrees out of the boosted cells and then run it and see what happens. In all honesty, you should be able to run it like it is no problem. I have yet to hook up my knocksenseMS to tune it out, but I know that map is safe on my setup. Perhaps not optimal, but safe.
