Wheel is available Individually or with the Complete Kit
•12-1 Tooth Billet Wheel Available (12 minus 1) - The removed tooth on the 12-1 would be the 105deg BTDC tooth  
•Notice to AEM Infinity Users: AEM Software does not allow for configuring the skipped tooth using this wheel (most other ECU manufacturers have the required feature). 
•A modified 1 pulse per revolution Cam signal is still required (1g, 2g, or EVO). While the 12-1 skip tooth on the crank sensor delivers information for the crankshaft position, it does not know if cylinder 1 is seeing overlap or compression. A single tooth cam sensor with its one pulse per every 2 engine revolutions is what provides the signal to tell which revolution the engine is on. If the camshaft sensor is not modified, it will have one pulse each engine revolution and this is not enough information for the ECU to determine which revolution it is on.
