Engine Conversion - Tachometer Issues
On the subject of engine conversions.... one of the problems that often comes up after the swap is getting the tachometer to indicate properly. Reasons include different number of engine cylinders, or new ignition signals that are incompatible with the original tachometer design. I had this problem when swapping a 911 engine into my '66 912. Here is a link to a post where I discuss the development of my tachometer adapter that enabled me to use my original tach and have it indicate correctly with the new engine:

I agree. Excellent communication and very quick shipping.
I recently purchased the Tach-adapt device for my conversion: Car: '74 911 New Motor: 5.7L GM small block Problem: Tachometer was reading significantly higher than it should, as Bob put, 1.33 times what it should be. The needle also bounced erratically as it was unable to handle the HEI signal. Resolution: Installed the Tach-Adapt device in about 5 minutes, tach reads right on now and the erratic bounce has gone away. Thanks Bob. - John

Hi, just saw your comments. VW VR6... that sounds like a fun adventure. I'm not familiar with that motor... what type of ignition system does it run? Does it have a Motronics box controlling injection, spark, etc.?
Also important, you didn't mention what car you are putting this VR6 engine into. What year and model (911, 912, etc.)? Generally, my solution fixes about 90% of the problems that occur, so keep talking and we'll work this thing out. You can also see info on my website Home Thanks much ... Bob |
