CLT placement

Post by 1955cc66bug »

So from what I've read, the best place for the sensor is in the airstream under the heads, or maybe in the valve cover....a friend mentioned using a head temp sensor instead, like one from a T4, placed in the stock loaction on the head (my 043's have the boss for this) any reason not to do this? to hot? Thanks for any input.

I was gonna do the same thing, but someone told me the T4 sensors aren't the greatest. Just stick a water temp sender in the rocker box, you're only concerned about the first 200 degrees of engine temp anyway. After that, you can consider it fully warmed.

So no advantage to a head temp sensor at all huh...? I have a CLT already, just wanted to make sure I was gonna be using the best combo possible. Bout how long does it take for it to warm up when it's in the valve cover? I make a lot of short trips..not optimal I know, but just the way it is.

This is where I placed mine. I have it set to stop warmup enrichment at only 110 degrees of oil temp. Time depends on the outside temp. But normally about 10 minutes.

Same for me, about 8-10 mins for full warm. Depends on if you're letting it idle or driving it though, driving it right away puts more heat into the heads quicker.

Thanks for the replys fellas. Next question is, since I drive to and from work, about 5 minutes each way (I know) what, if any harm would be done in tricking the ecu into thinking it's warmer than it really is...? Obviously the heads get the hottest, quickest, so I'm thinking valve cover would be my best bet...also, I have MS1 extra, do I have the option of turning the enrichment circuit off at any given temp?

You can turn the 'virtual choke' off at any time you wish, just program the warmup table with 100's so no additional fuel will be added at will. Only thing is, will it idle with a lack of fuel when it's not truely warmed? I know mine won't, but adding like 4* timing when cold helps things a lot. Having an idle valve is preferable, since engines will generally tolerate a lean mixture at higher RPM's whether cold or warm.

NICE! Thanks Panel. I'm still thinking valve cover.

I think I might go back also.

If you put it in the valve cover I would put it in the bottom. The valve cover is isolated via thick gasket so I don't see how it heat soaks fast. At least at the bottom it will pick up oil at a cruise.

I was kind of thinking the same about the gasket....But it seems many are having good luck with it there. Like anything, it can be changed if I don't like the way it's working :)
