Temp Gauge Modification

[loco_ola]

I was wondering if anyone had tried, or had any thoughts on the surf mod for the temperature gauge to make it work more accurately?

Why is the modification needed?

There is a deliberate "dead zone" on the stock temperature gauge (see picture).

On the stock gauge, all engine temperatures between about 70 C and 100C give materially the same position on the gauge.

Here is the information for the 80 series from which the idea was taken.

I replaced the gauge with an original discontinued "new" one from ebay. at 95 euros, did little else then just stopping having temperature spikes.
now I use an auber pid and a vdo probe, can confirm that the needle on board doesnt move much.
