I have a 2003 lightning with a built JDM long block heavy modded with lots of $money tied up in it. How important is pyrometer this gauge is just to monitor exhaust heat is this correct and just what should the exhaust heat be. Probley would give tell tale signs of something wrong with high temp reading and the ford racing pyrometer gauge. And where shpuld the probe be mounted on top of the manifold or on the side is it worth the money thanks

 

Never really heard of a reason to put them on a gas motor.

The gauges you want on a modded L is.

Wideband
Fuel Pressure
Tranny Temp
Oil Pressure
Vac/Boost
Aeroforce gauge

Thats the set up i have, shows everything i could ever need to know.

pyrometer is handy if you have a turbo setup.. other than that.... Junk

 

I am in processing of getting wideband, autometer probley just as good as any mabey better than some.??

 

Or for fine tuning an adjustable electric fan controller

 

The Autometer wideband is nice, i have a Innovate DB series. Many people say that Innovate is the best!

You should look into the Aeroforce OBD2 gauge, its great. I have mine set up to read 8 different things, it shows 2 at a time and changes like every 3 sec.

Actually, if you are talking about an EGT pyrometer, it is another very useful tool for gathering data on how your motor is performing. Now days, most people seem focused on the wideband guage. Before the affordable widebands hit the market several years ago, I got an Autometer dual EGT pyrometer with memory recall as I was having irritating tuning problems from the local tuners and sure enough I had uncomfortably high EGT temps at WOT once I got the gage set-up. Later when Sal was finally able to dynotune my truck, I could see the EGT temps change as he would adjust the tune, of course he was using an $8,000 wideband, or whatever, for his tuning. Anyway, surprisingly, as he zeroed in on the final tune, minor changes in the fuel table and/or timing made relatively big changes in the EGT temps without any significant change in RWHP. So in the final tune, I had him adjust the tune to get me lower EGT's since it really didn't significantly affect the RWHP.
Anyway, I still have the EGT guage as I newer switched to a wideband, and it more or less acts as a wideband for me.
The EGT is a useful tool, but with the affordable widebands on the market today, that would be my choice if I had limited space for guages.

 

Gauges are good, but if you are worried about knock, google "knock controller demo".

 

Since I have so much money tied up in engine i am getting autometer phantom wideband EGT pyrometer i already have the areoforce intercepter oil temp transmission temp differential temp two transmission coolers with fans etc.

 

I too used the EGT before affordable widebands were common, but have a dynojet WB too now.
Just out of curiorsity what kind of EGT temps do you run at idle, 70 mph cruising and WOT.
I run about 800, 1200, and 1350
at A/F of 14.7, 14.7, and 11.5

 

775 1150 1250 TEMP
A/F 14.3 14.2 12.25 THANKS
