Re: IAT range



I have injectino set up on my mini, and as it's only being sorted out.. i found that connecting the temp sender up, but not mounting it in the head, helped me heaps, in that the computer thought the engine never got hot enough, for it to go into closed loop (no O2 sensor.. leaded fuel) it helped me sort the injectino out enough, by just modifying MAP inputs to get the car driveable... Of course when my skills permit i will remap the chip and do it all properly but for now this serves me well...

Regards
Ben

the manual I had for the '77 analogue Caddy setup had a resistance chart for the temp sensor in it. it is on incoming under '77cadman.zip. I am wondering
if the later digital stuff is the same?
