I see the MAFTpro comes with the wideband o2 sensor and while the MAPecu2 has --On-board support for display and logging of popular aftermarket wideband Lambda sensors/controllers, it does not come with the actual o2 sensor.
They are about the same price but then you have to buy a wideband sensor for the MAPecu2.In that case, the MAFTpro is looking better to me pricewise. I guess it just comes down to personal preference,but i have no experience with either. Also im not too sure on the reliability with the on-board MAP and Boost controls on the MAPecu versus the external MAP and boost control solenoid.
