i personally build this ecu. i used a virgin obd1 P72 core. This particular ecu did have a burnt Q31. i removed it and covered the trace with some black paint. for those who do know Q31 controls the evap canister, and is commonly burnt out when you accidentally plug its plug into the intake air temp sensor. most people with built/tuck cars eliminate the charcoal canister. it is not needed for modded cars. the ecu works 100% and there are no check engine lights. The s300 was brand new out the box. it is the version 2 unit. i tested this ecu with my Moates engine simulator. everything works as it should. The P72 ecu has a knock board and IAB control. this is a perfect ecu for GSR and H22 setups. the s300 will come programmed. it will come with everything you need to set it up. all components will be installed in the p72. This is a real p72 ecu
decided to stick with my Neptune for now but eventually i am going to go for the pro efi 48, so the Neptune setup will be for sale to p28 with Moates demon and neptune license $500
