Topic: Poor Man's EGT / CHT Monitor

[Goeytex]

Get a PID Controller from EBAY.  Make sure it is a 12vdc model. 
These come with a  3 ft   "K" type thermocouple.

Has a bright  Digital LED Display that constantly reads out
temperature.

Panel mounts in the dash. 

Configure it so an alarm sounds or a light comes on when temperature
reaches a pre-programmed value that you set. 

Can be used either for  EGT or CHT.   Or use 2 and monitor both.

Total cost ?   36.00 ea  plus shipping.

PM me and I'll tell you exactly what to get.

Sounds good but you really need a max recall feature to do any tuning.   

Also will that thermocouple work for EGT?  I know good EGT sensors are expensive because they need to react fast and cover a wide range of temps.
If you could incorporate a max recall it would
 be a better gauge.

No Max recall with these.  But then again it is a poor man's monitor.  Make some  laps with no traffic and take a peek at the display from time to time.   Beats having nothing at all.  And the price is  good.

Any   "K"  thermocouple  is good from  -328 F  to   2282  F. ...  So yes,  it will work fine.  

The "reaction time"  is not so much a function of the thermocouple (as that is almost instant),  but of the electronics that reads it.  In the case of these units that is every 250  milliseconds or 4 times per second.
