So i got my scanmaster hooked up and ready to go. Its giving me malfunctions codes of 15 and 23 which is Coolant Temp sensor low and Air temp Sensor low. So i need help with what to do to fix that problem. Thanks
 
Code 15- Bad coolant sensor or it is unplugged.
Code 23- Bad MAT, unplugged MAT or broken wire.
These are listed in your Scanmaster Instructions. Keep us posted. Brad
 
Does the MAT Have something to do with The MAF? Because I have the 86 ecm with the tt chip but i still have the stock maf on. I have the LS1 and translator but having put that back on
