what temp sensor to use for MAF conversion
 

Im not comfortable using the autothority's variable resistor that is hard wired into their maf system.

does anyone know the BOSCH part number for an air temp sensor that will work with the DME. or otherwise replace the stock temp sensor in the AFM?

I have been searching for this part number for days.

the only thing i can come up with is the Bosch Temp. Sensor #0 280 130 039

I have a porsche 944 turbo with a list of mods in my signature block

This is the spec for the NTC thermistor in the temp sensor if you can get one that matches the relevant part -30 C to 80 C you can use it.

sox you have too much time on your hands. go drink a beer. :)

Thats when I do my best work Nize :)
Actually tequila is my brain booster of choice.
Sox

have you tried tarantula azul? it's pretty good.

Tequila made in Italy ?? actually I have, its good but I like straight stuff without the citrus flavor. I like Herradura Tequila (anejo reposado) and Milagro for sipping.
