I've heard of people using an external MAP sensor (for instance, a 5-bar sensor in some cases) and connecting that to the FIC's MAF input. At the top-right corner of the FIC's fuel table, there is a small icon that you can click to open a MAF-based fuel table. Unfortunately there isn't a place to tell the FIC how the sensor voltage relates to actual pressure, so you would have to do this on your own. If you still need to clamp an OEM MAF sensor, you can use the Analog A or Analog B channels for that.
Thanks, SB. It is exactly what I am going to do! Now the Analog A map is used to clamp external MAP sensor. And MAF map is used just to clamp MAF sensor. What I am going to do is to intarchange MAF input/output wires with Analog A input/output wires. And I can tune everything by external MAP using MAF based maps for it!
This might not work well with the OEM MAP sensor from a non-turbocharged vehicle. The sensor will only be able to measure a certain amount of manifold pressure (for instance, maybe 8 psi), if your actual pressure is higher than that (for instance, maybe 12 psi) the sensor won't be able to display anything above its maximum value (for instance, maybe 8psi).
Ny OEM MAP sensor can measure the pressure higher then 30 PSI however tha car is non-turbocharged. I have the old logs I have recorded when my FIC onboard pressure sensor was working fine, so I can relate the engine pressure sensor voltage with the pressure AEM FIC onboard sensor did measure. I did try to relate it already using AEM log application (I did create there Engine Load/Analog A input plots and which show the relation qute well.
Have you tried contacting Tech Support to ask about having the FIC repaired?
No, I did not do it. Just worte it here in forum. The problem is that I am from Russia and sending the FIC to USA for the repair is not very suitable for me. If I could get the FIC onboard MAP sensor I could change it myself... Dont you know SB if I can get it? Maybe you cold give me an idea whom I shall ask for it or where I can search for it.
Thanks in advance,
