trwebb26 Posted January 20, 2006 Share Posted January 20, 2006 I know some of you are running the GM CLT sensor with your Megasquirt setups. I have purchased this sensor, but it does not screw directly into the stock thermostat housing. I'm curious about what you did to make the sensor fit. Pictures would be GRRRRREAT. I think I'm going to drill and tap out the thermotime sensor (the one on the front of the housing... on the drivers side) hole bigger to accept the sensor and plug the rest.

trwebb26 Posted January 20, 2006 Author Share Posted January 20, 2006 I considered doing that... but the sensor part isn't in the "flow" of the coolant. I've been reading on the megasquirt forums trying to figure out if this is a big deal or not. Obviously the way you've done it would be the most simple, but I'm a bit concerned about water not flowing around the sensor leading to inaccurate readings. Thoughts?

proxlamus© Posted January 20, 2006 Share Posted January 20, 2006 um.. it flows... Notice the hose connected to the fittings as well?? Thats for the coolant to the turbo Quote Link to comment Share on other sites More sharing options...
trwebb26 Posted January 21, 2006 Author Share Posted January 21, 2006 So the only coolant that the sensor sees is the hot water from the turbo... I don't know if that is a good thing either. It probably doesn't really reflect the temperature of the water running through the engine (water from turbo probably not the same temperature as the water from the block).

mobythevan Posted January 21, 2006 Share Posted January 21, 2006 the water from that area heads out to the turbo, I know because I helped set up that part and we made sure of it. We didn't want hot water from the turbo hitting the sensor first. Quote Link to comment Share on other sites More sharing options...
z-ya Posted January 21, 2006 Share Posted January 21, 2006 I drilled out one of the old sensors and and then tapped it to 3/8" NPT. As long as the sensor is below the T-stat, it will get an accurate reading of temp for the coolant in the engine. Quote Link to comment Share on other sites More sharing options...
zguy36 Posted January 26, 2006 Share Posted January 26, 2006 Just a thought, but I am using the stock cylinder head temp sensor instead of a coolant sensor. The only problem with this is that these temps get much higher than the water temps and make the warmup enrichment a little more difficult to tune. -jeremy- Quote Link to comment Share on other sites More sharing options...
mobythevan Posted January 26, 2006 Share Posted January 26, 2006 yeah, the install guide calls out to use the CHTS, however there isn't one on NA engines like Ryan had IIRC, so some people will be forced to use another sensor. Quote Link to comment Share on other sites More sharing options...
jkube Posted January 27, 2006 Share Posted January 27, 2006 I used the stock 280z sensor and used easytherm to recalibrate the MS settings. No problem to date If anyone wants the values, just send me a PM Quote Link to comment Share on other sites More sharing options...
