too much timing in the basemaps?

I was checkout out some of the basmaps and the ITR one grabbed my attention. 32.75* of timing at 7000 RPM's for some reason that doesnt sound right to me. If it is please someone correct me cause i thought u didnt wanna run over 30* in the Higher RPM's

BTW this is with Hondata S300 V 1.09

NA or Turbo?

If it's NA...it looks fine to me.

I had the same question. THere is also too much ignition in the 623mbar column causing too much pinging to my stock JDM ITR (alhtough I had lowered timing 2 degrees everywhere due to the higher compression of the JDM model). I removed as much as an additional 2 degrees everywhere and in the 623mbar column, 2 degrees on top of that. Now my car drives fine, is very powerful and I have no detonation.

This calibration was from a stock ITR which was dyno tuned, and 32 degrees timing is what gave the best results. There are significant differences in fuel between the US and other countries.

That is true Hondata. I had no pinging at full throttle but the 623 mbar column was way over advanced. DId you dyno tune all loads?

Which calibration do you mean? The ITR calibration does not have a column at 623 mbar.

Sorry, I meant the 535 & 650 columns. At my engine I found that I had to back off timing by 3 or even 3.5 degrees to stop detonation even with premium unleaded (100RON europe, should be equivalent to US 93 or 95) at these loads. I know this helps with driveability and fuel economy but I had detonation even at such load/medium loads.

However my engine has 11.1:1 compression like the JDM model and thus 1-2 degrees less timing is expected.

One more question about this map: At 7000-7500rpm the timing falls sharply by 5.25 degrees in just 500rpm. Is this normal? Did it work on the dyno? I am going to dynotune soon my car and see if it likes it or not. Your basemap feels strong on the street though.

The calibration is what gave the best results for this vehicle.

You must remember that this was a US ITR...B18C5 has 10.6:1 compression.

Yes. I said that in my post. I am going to dyno my b18c6 till the end of sep and post some results here just for the discussion. I'll also post the calibration if you want (since my b18c6 is basically stock. Only a DC JDM header and 2.5" exhaust).
