First up, consider the MS3 instead. There's a few guys on the forum and at mazda-speed.com running a MS on their MSM so PM them for their thoughts on this.
>1) What wideband are you guys running?
Innovate MTX-L - includes gauge too.
I run an Adaptronic Select ECU connected via the gauge's digital output. During the Wideband O2's warming up period, data from the gauge is rubbish and the Innovate digital output actually indicates when it's warming up which the Adaptronic ECU can detect and ignore the data during this phase.
The MTX-L also has an analog output which I don't use.
>1a) How hard is it to configure it?
Simple, just requires a bit of wiring work.
>2) GM IAT or stock?
THE GM IAT, being an open-air sensor, responds much faster to temperature changes than the stock sensor so from that aspect is much better. Most aftermarket turbo guys use it because they don't already have this sensor so need one. Since you already have the OEM sensor in place, you may as well use it.
>3) There's no need for an external MAP sensor correct?
Can't speak for the MS but many ECUs have MAP sensors bulit into them (eg. Adaptronic, Haltech).
>4) USB to Serial Converter Recommendations?
Try and find one with an FTDI chip, they work everywhere.
Some adapters use Prolific chips which don't work on some OSes.
