ok so i got a 1990 tsi awd..the kid i bought it off of is supposedly a dsm 'guru'.my car has a 7bolt head( 6 bolt block ) my tach is hooked up to a noise sensor he put on the block? so after idle my needle either spazzes up and down or down to zero. he claimed the only way to get it to work is to put the 6 bolt head on. it wouldnt bother me so much if i wanted to keep it stock. but i want to do a gm maft and it requires accurate rpm readings to be useful. this also confuses me on how can my ecu give me correct fuel trims if it doesnt know the true rpm.
help.. how can i get my dash tach to work accurately? i dont even know where to start
