Default MAP to MAF conversion from UTEC??? Do it today with Xede.

turboXS advertising of future functions
-MAP to MAF signal conversion
*Eliminate the Mass Air Flow sensor and run any turbo you want
This is really interesting - Xede can use a few different inputs as loads and it can send an absolute signal to the ECU instead of a scaled signal.

I put my money that someone with some time, know how and understanding of how the ECU would respond to this could run setups without the MAF now!

Make a table with MAP as the load, set MAF as the input variable (not that it matters but something needs to be there), set MAF as the output variable, set the math function to absolute output and the adjust range to +/- 5v. Make the map 20x20 because I bet you will need it. Your fuel map will now be based only on your MAP and engine rpm - based on the voltage signal you send to the ECU as your MAF signal.

You can do today what Utec is advertising as a future function - run without a MAF sensor - and convert the MAP signal into a MAF signal.

There you have it - now this would be fun to do! Got wide-band?

Come on someone step up, I wanna play.
