Clear as a bell
All I can say is I am glad I bought a GPS so i can find my way home.
Hymlee I dont want to bother you as I know you have a ----load of work to do , but a question to others I know are monitoring this thread--how does the pcm know when you are in boost and when you are not? Or does that matter?

However, the PCM tables are tuned to deliver fuel and spark based on the MAF input as compared to the known Ve of the motor and the other sensor inputs.
If those MAF values go above what is possible at atmospheric pressure, you would just compensate accordingly.

That is why I pay Jeff the big bucks. LOL
Actually - in older systems using a MAP sensor (speed/density), the PCM would need to take into account a number of factors then calculate the mass air flow. In my opinion, MAF's are a good thing - if they are calibrated correctly. It's common practice on V8's to get rid of the MAF and go with a MAF-less tune, but I don't think that is the best way to go.
So I pay Jeff the big buck so I don't need to spend time replying like I just did. Dear me, I'm a lost cause.
Cheers,
Hymee.

Or is the new beta going to "replace" the 2.0 sCANanalyser ?

I don't mind buying your current software right now either...
I need something...and they who can deliver first wins my money...
The Aussies seem to have PCM down tho...

Well...seeing how I'm designing a system to work with the beautifully matched snail he has...
And my need for a engine manglement solution...
And his connection to Hymee...
Yea...if you have a fraction of a point of intelligence...you would know good gear and sound advice when you see it...

is autotuning just a dream of mine?
-write target lambda (or afr) map, forget about injector pulse times
-pcm monitors wbo2 and compares against said map
-pcm self corrects fuel trim to get to target
-continuously rinse and repeat to account for environmental or other changes
