Hi Guys!

Found this forum all the way from Sweden and am very impressed with all the cool builds and the knowledge! I've been reading for days but would like some tips for a :noob: who can't learn enough quick enough :D

Background
- Car Mx5 1,8 -95
Bought a MSNPNP 9495 from DIY and while this was being shipped I got offerd a...
- 2001 1,8 NB engine with high compression, bigger valves, springs, sharper cams, tuned exhaust manifold, 2,5" exhaust with race cat and a little video of it reving @9k rpm ::eek: I couldn't resist!
-The output was supposedly 220-240hp, If i land around 200 i'm happy.
-Do i need to mention this will be no turbo or compressor. Is N/A the correct term?
-Threw the engine in with a aluminium cooler and 25 row oilcooler.
-Changed all the electronics to be identical to a 9495 Miata.
- LC1 lambda.
- Filled it with E85 (much cheeper than 95 gas and se if I make more power)
Took it for a spin with a ignition table with very very low ignition 12-15* and very rich mixture. Lots of popping :D
Now to get it running good enough so that i can test it a bit before going to a dyno.

All the power is hidden in the spark, so i will be buildning ear phone so I can listen for pinging / detonation.

But where is the right ballpark to start?
From all my reading comparing I've come upp with this inclosed picture. Not tested yet and don't look at the VE table, just added 5 all over my old one and will ve analys it.
But I would like a spark table to start with that isn't turbo... More retardation on N/A than Turbo?
Would this be a ok place to start ofcorse listening for ping, and start logging?

And of course the car before I got the last silencer on ;)
