First off, I am working on a 2004 AUDM Mazda RX8.
I have a logcfg and its at least logging. rpm, maf, coolant_temp, wbo2_commanded and calc_load are all fine however I have a few problems I am hoping someone can help me with:
1. stft & ltft show values like 95.3125 and 101.5630 respectively instead of +4.6875 and -1.5630, secondly the values dont seem to match up with other tools like Dash Commander which is showing a pretty rock solid -3.1 for ltft (101.5630 is also pretty rock solid in the output of my log file). To fix the 95.3125 instead of +5.3125 I could just do:
paramname=stft1
mode=0x01
paramid=0x06
databits=8
scalingrpn=128,x,-,0.78125,*
But that doesn't help with the fact the numbers don't look right.
2. Again, Dash commander shows 14.9/15 actual AFR (Lambda of around 1.00-1.05) yet I am seeing values like 1.4328 in my log file. The following is commanded and actual lambda from a log file
cmded actual
0.9045 1.4328
0.9045 1.4328
0.9045 1.4328
0.9045 1.4328
0.9045 1.4328
0.9045 1.4328
0.9045 1.4328
0.9045 1.4328
0.9045 1.4328
0.9045 1.4328
0.9045 1.4328
0.9045 1.4328
0.9045 1.4328
0.9045 1.4328
Any help on these issues will be appreciated.
