Hi, I am running MS PNP2 with a 1993 miata.


This is what happened when I went to install the GM IAT sensor off of DIY autotune, I have it threaded in good, wires go into pins 1 and 6 in the MAF plug, The problem is when i go into Tuner Studio and select the "Calibrate Thermistor Tables" tab then change it to air intake temp and select the GM sensor then hit "write to controller".

Once i hit "write to controller" it pauses then this message pops up (see attached picture).
Has something to do with CRC Mismatch, Any advice on how to fix this?

Also I can not calibrate the AFR table as well, same message pops up.
