I posted a while back but was not very too the point about it.

So.... I know quite a few have a PSi3 SECS unit, so want/need to know the following. Mainly how to interpret some of the data. Whats useful and whats not etc.

Boost = obvious
Battery = obvious
Temp = obvious...

However air fuel ratio, lambda, knock, etc... I realise some of this will vary depending on variant, and level of tuning, but is there other data on there that can be watched for warning signs of impending dooooom ??
