Default I guess you would want to...->

make a analog 0-5volt curve with "speed density" -> "maf-signal" ...

Have everything scaled correctly and you would be maf-less, but engine would still think you are running a MAF .

Is this unit realtime programmable ??

Also, it support a wideband-sensor to modify the analog output even further ?
basicly wideband closed-loop ?

that would be sweet, and it DOES sound useable. Question is, how well does it really work...

keep us updated!

Default I was thinking of changing the MAF transfer function to a linear line...

and then tuning it that way.

It is programmable real-time, and it also has a temp correction function, which most do not have.

It does support a WBO2, and it does have a fuel-loop table, so I could theoretically turn off the O2 sensors in the ECU, and then let the SMT7 do all the work.

First thing first though, get it running

Default sounds nice... ->

I am writing a followup over at the Yahoo open source ecu group. I guess it falls better into place there.
