QUOTE(MikeM @ May 26 2020, 10:55 AM)  I just used one of those on my DJET car but now people are saying it's too far from the engine for accurate readings? Thoughts? Mike The lambda needs the heat to read correctly, ideally 750F. I've measured a 100F difference just from a header collector flange (with gasket) to the muffler flange. Mufflers do get hot, but nowhere near 750F. Ideal it's 2 feet from the exhaust port for NA or 3 feet for turbo/SC and before the cat if you have one. On a 914 the best you can do is about 2-1/2 feet from the port which should be OK. The innovate clamp is idea I tried (home/shop made) back in the 90's/early 2000 and found it gave me inaccurate readings. |

It probably wont drive you as nuts as a head temp sensor gauge does but may be more usefull to have installed when you are having running issues. If you dont mind the look where you have it installed I would probably leave it in.
Probably more usefull on a carb'd car where mixture can be easily tweaked and issues can be addressed at side of the road. |
