Useful instructions on how to calibrate the gauge (once its working!) My tach is a 0-4000rpm, with digital hour counter and inductive pickup from alternator. These gauges have a tendency (fault!) to intermittently display the hour counter, eventually the display is permanently blank. The fault is due to a ribbon cable attached to the LCD display using a process known as chip on glass - practically impossible to repair without specialist tools/knowledge. Unfortunately, VDO’s original display (LPH3930-2) is custom made for them, and can’t be purchased, so rather than trying to repair the original LCD display, I’ve chosen to replace it with a modern alternative. I spent many hours decoding the old signals and determining what they mean, the result is the knowledge to be able to build an adapter and understand the original LCD protocols.įor those that are interested, the original LCD appears to use a chip similar to PCF8562 ( ) The next problem is that modern displays “talk” differently, so an adapter is needed to convert the old signals into new. So, this project uses a tiny computer (AtMega328) and an organic LED screen. The actual parts I brought and used for this project were… These parts are readily available for home hobbyist use.

Start by programming the Arduino (ATMEGA328) using the Arduino software - there are hundreds of websites devoted to this topic so I won’t repeat them here.

The source code is available from me, send me a message on the forum with your email address and I’ll sent it to you. Next, you will need to connect the display to the Arduino. To make the display fit inside the case, I had to remove the presoldered header pins and replace them with 4 wires. Make sure you leave these wires long enough to give yourself working room 15-20cm long is great.

Safely remove the clear plastic “glass” from the unit and keep the rubber seals.(did you know the gauge was double glazed?)
