Actually CHT's go up because you are burning the fuel more completely thus higher temps. Its not a big deal for a properly cooled engine, however some planes have experienced some issues. For some reason the only EI to really cause the problem is the certified LASAR system.

Dual light speed Backup?
Walt
With dual LS what do you have for a backup incase of electrical failure? I really like the idea.
Thanks

Switching to P-Mag
I guess that I'm the gageteer sort. I've just received a couple of Pmags for installation on my RV-4 (180/CS) currently flying with Slicks. I chose the Pmags primarily because of space limitations...no cigar box sized unit to find a place for.
Another thought just came to mind. If one switches from mags to Pmags, are folks considering this a "major" change and running it by the Feds? Or just installing the EI, making the log entry and flying?

Russ,
I added the B&C BUG (8 amp back up gen) to the system which can carry both LSI's and the essential bus no problem.

I went with the B&C BUG with single battery. When I switched to duals I replaced the Hall effect module with the dual crank pick-up. I was having some oil seepage with the Hall effect modules so decided to get rid of all the moving parts!

Mitch,
I am getting ready for my first flight and also for a switch to an E-Mag on the right side. I asked our DAR and he said that the switch would fall under minor mods, not adding any time to our 40 hours. If it would have, I would have swapped prior to the first flight, but I want to get some comparison numbers. I plan on posting them.
