KAMFZ: Motor: KAMFZ (Grad KW vor OT) 4-Zyl. 126 6-Zyl. 96 8-Zyl. 54 So 126/6= 21 tooth for 4 zyl and 5 zyl 16 tooth for 6 zyl and so on Title: Re: What is offset betwen GMT and missing tooth Post by: Speedhunter on February 20, 2025, 08:04:14 AM Wtf GMT means?....

SY_GRUNDWERT=72 degrees from TDC to SW-bezugsmarke, plus 1 tooth to the edge of missing teeth. For example, if you have aftermarket ecu, you put 78 deg as TDC offset, timing should be spot on (depending what your ecu uses as ref point). |
