I have recently been comparing WOT power runs with and without the Dawes and have noticed that the ignition, knock correction and boost graphs seem much smoother WITH the Dawes and less smooth without the Dawes! I can kind of see why this would be the case. I'll post something on here later tonight when I work out how to present it easily.
The main difference I notice is that the Dawes MBC seems to provide much better boost control under WOT conditions rising quickly to a slightly higher preset limit then tailing off much slower than our stock map is programmed to do.
Further to this post please find below a side-by-side compare of a WOT log in 1st, 2nd and 3rd gear with and without my dawes. Logs were made on the same day. Original csv logs also attached for the more interested.
Interesting to see that boost and knock graphs seem 'smoother' with Dawes. I'm not saying this is better - just an observation. Also just noticed that the maximum ignition retard is larger WITHOUT the Dawes. Also ignition graph looks smoother WITHOUT Dawes.
Anyone know what combination of graphs is best?
I'm after setting myself some goals on tweeking this map e.g.:
1. modify 'boost maps' so boost doesn't drop in such a steep slope
2. get IDC to around 80-85% max
3. perhaps improve ignition retard even more?
Ideas most welcome.
