I used an Innovate LM-1 to tune several Electromotive and Haltech systems and it has really worked well.
In my turbo car, I have the sensor in pretty much the stock location (4-5" down from the turbine outlet on a non-stock downpipe)and have experienced no problems.
I've interfaced the LM-1 analog output to my Electromotive TEC2's O2 sensor input, and now can datalog true AFR along with any/all measurements available to the ECU. This makes tuning stupid-simple with a programmable system.
The LM-1 is a pretty capable data-logger on its own, but you have to have the optional "RPM Converter Cable" if you want the capability to record RPM and 3 more 0-5 Volt signals, such as MAP, along with AFR. The RPM Converter setup is non-intuitive and confusing, though. The Innovate software could be more user - friendly.
