Base Map for Water Injection

Since my last post, I've been doing several rounds of tuning to get a good base map for water injection and I think I've got it. This map is named "20081208_timing_tipin_fuel.hex".

With water injection, I've found that I can go as high as 1.5 bar of boost with no knock. My IDC is about 80% which I feel is quite safe. At 1.7 bar of boost, I do not have much knock. My max IDC will hit 95% occasionally.(see below)



No methanol needed. Only slight knock during normal driving which occurs vey rarely.

The object of this timing (part 2) is to go as far as possible with just water injection.

The only changes I did to get to this base map is to change my open loop fuel table (run leaner to 11.2 in high load) and my timing (increase).
