Does any one have the stock map sensor readings for a is200 rpm range. I need to create a maf clamp map on aem fic to try and sort my silly fuel cut.
Thank you in advance :-)

I believe the Black Boxes are set to 4.34v to prevent fuel cut, and I think Patrik has experimented upto 4.44v.

Im sure Stav will be along soon to confirm

Yeah I know that bit. But I have a aem fic and the maf map needs voltage for different rpm from the map sensor. So need to fill the map in and put a voltage clamp across the rpm range.

You can put the clamp at 4.34 across the full range surely? You don't need to know the input readings as the aem can read them itself from the standard map sensor surely?

All the aem want is a number not to go above at various points in the range so putting 4.34v in will suitable.

Hmm. Works on the ultimate.

What happens if nothing's in the boxes? I have some info somewhere but it's pretty rough. I'll dig it out.

Tried running it with nothing in the cells and the car won't start :-s. I am going to check all the wiring at the weekend from ecu pin out to the fic controller. Something just doesn't seem right. Wish I had just left it with the fcd stopping fuel cut. It would be nice if any one else had a fic and could see the maf map they had.
