MMP 6-4 cylinder tach converter (for VR6 swap into 4 cyl) without D/A converter

MMP 6-4 cylinder tach converter (for VR6 swap into 4 cyl) without D/A converter

Regular price $209.00 Sale

MMP's popular line of tach adapters have been used in engine swaps worldwide. Our 6-4 D/A converter changes the digital output signal pulse from the 6 cyl ecu and converts it to the correct 4 cyl digital signal, which is need for the factory 4 cyl tach. 

Some competitors modules feature dip switches to configure the adapter for multiple applications. We have found these prone to vibration failure, due to having a mechanical switch, and moisture ingress.

Our units are fully sealed and configured with a simple 4 wire installation. They are compact and can be tucked behind your instrument cluster. They are so durable that the first adapter we produced is still in service and going strong 15 years after being made!

Some example applications include...

VR6 12v swap into Mk3/Mk4 4cyl

(R32) swap into Mk3/Mk4 4cyl 

Please refer to your Bentley manual for the donor vehicle tach output, and your vehicle for tach input. Contact MMP technical for inquiries with your engine swap..
