There is pretty wide range of adjustment for your 6 zyl (as it says on the back of yours). As previously mentioned it will be close - but not accurate by going to an extreme of adjustment to get yours near 4 cyl range. I have a collection of both 6 and 4 zyl tachs available. I have visually studied the "guts" and as near as I can determine (not being an electrical engineer) the difference is in a single resistor. I was looking to modify a 4zyl for my VolvOldsmobile V8. -- Dave
