Your understanding of german is not so bad, you passed the test.
Maybe we start an course english/german here, first let us collect all the kinky words

Your map looks not so bad, maybe you could pull a little bit earlier in the higher boost levels.
Here is my i/g setup, depending on 12deg BTDC and an max boost round about 8,5 to 10 PSI (i use kg/cm2 units, so the map looks a little bit weird after changing to PSI).
I reduce on max boost to 8deg BTDC because i lowerd my compression with an metall plate, for your setup i would prefer to go to 6deg BTDC.

metal plate? what do you mean? u running different cylinder head gasket? i have read on some posts about the timing and everyone seams to retard 1deg per psi. Joe even mentioned that he had to retard 1.5deg on some occasions. This is my weakness. i just want to run the car on the safe side now till the Water injection is installed. That is why i posted a new thread about a standalone Knock sensor that can be added. do they have better knock monitoring in Deutschland that we can explore?

I have a plate between two cylinder head gasket to lower my compression, to prefent detonation.
But itīs really oldschool, wiseco are lying here for my new motor.
Donīt care about it your i/g setup, it is already ok.
I think water injection is also an good upgrade.

Here in germany unfortunatly whe have no knock system, we always look what you in the us are doing, here are not so good sources for the miata stuff.

A friend of me has this one bought in the uk, but not installed

After turbocharging, I found that even with an intercooler my particular engine (on 91 R+M/2 fuel) tended to ping a lot. This was with 10°BTDC base (verified with a dial indicator on the piston) and a straight 1° of retard per PSI. I didn't use any magic formulas (or dyno time) at that point, I just set my ignition table to what wound up being about 1.5° per PSI, and that worked. I no doubt could have found a few extra HP by spending some time refining it on a dyno, but I was lazy.

Now that the WI is in I'm running a somewhat more aggressive map, though I am still pulling some timing. At 12 PSI at 4,000 RPM for example, I'm at 7° retard, decreasing to 4° retard by 6,000 RPM. Still haven't gotten off my **** and gone to the dyno yet. I'm sure that I can get more aggressive still.

With an NA (90-97), you set base timing by jumpering the TEN-GND position in the diagnostic connector, loosening the lockbolt on the camshaft sensor and rotating it while observing the crankshaft pulley with a timing gun.

With NB, base timing sets you!

And I have an NB :(.. and im being told that 10deg BTDC is what it is stock anyways.. so im guessing I shouldnt need to mess with that anyways.
