Hey, have done searches on this site for B2200 fi, B2200 MS II, IAT resistance, etc etc. I got no results

I have converted my 89 B2200 that was carbureted to FI using original equipment parts from a 93 B2200 FI truck.

P.S. I am using the water temp sensor that is in the FI intake, not the one at the bottom of the radiator.

I am using Megasquirt II v3.57, I have everything wired up I just need to know the resistance for the IAT, MAP, and Temp sensors.

I have called several of my local parts stores, but they didn't have the info I needed. It was suggested that I go to all data.com and find that info, but I went there in the past looking for some info and they didn't have what i needed. I didn't really want to go and pay again, and not find this information.

If anyone has the info I need could you post it here, so that others may be able to find it if they need the same info.

Thanks,
Brian

thanks alot, I got exactly what i needed.

Here is the info to help others so they dont have to look throug all those pages.



IAT Thermo sensor (in Dynamic chamber)


Temperature-------------------------------------------Resistance

25 degrees C (77 degrees F)---------------------------29.7 - 36.3 K ohms
85 degrees C (185 degrees F)---------------------------3.3 - 3.7 K ohms

=======================================================


Coolant Thermo sensor (in the intake)


Coolant--------------------------------------------Resistance

-20 degrees C ( -4 degrees F)------------------------14.5 - 17.8 K ohms
20 degrees C ( 68 degrees F)-------------------------2.2 - 2.7 K ohms
80 degrees C ( 176 degrees F)-----------------------0.28 - 0.35 K ohms

=======================================================

Air Flow Sensor


Terminal wire \ Connection-----------------------Ignition on \ Engine running

B/Y--(Power Supply)--------------------------------------"Battery Voltage"
G/O--(Burn off)-----------------------------------------------------0V
G/B--(Airflow Mass)-----------------------------------1.0 to 2.0V \1.9 - 5V
G/Y--(Ground)------------------------------------------------------0V
B/O--(Ground)------------------------------------------------------0V
