According the the instructions listed on the site this can be user set to be used in wide band or narrow band. I cant find anything that says what sensor it uses. I really like these as the record and you can program to alarm(flash red) at your selected point. They have gauges for A/F and Boost but I dont see one for IAT. Could I use one of their temp gauges? I would certainly want all three gauges to look the same.

Thanks,
