I have a C6 efan and controller, similar to ADM's setup, and I was wondering how often do your fans come on? Do they all ways come on with the a/c? What temperature do they come on at? Alvin at Pcm for less did the programming and sometimes they work good and sometimes they don't. Like if I'm at a light with the air on for a few minutes the air gets warm and the temp gauge goes past 210, or if I'm doing alot of stop and go driving it does the same. Yesterday in traffic I got a warning coolant hot and i look down and the gauge reads 260. I know the fan works because when it does come on i can here it and it keeps the temp gauge at the notch before 210. I know Alvin knows what he's doing, so I was thinking it's maybe a bad controller. What do you guys think?

yeah i put in a 160* thermostat and i'm pretty sure i bled it completely. it just seems like since it's been getting hotter and with 100% humidity it's been going past 210*, sometimes it's ok and sometimes not, thats why i was thinking the controller?

Is the controller setup to be triggered the way alvins kit is? If not, might be the problem.

Mine acts similar.. However it doesn't get above 220*, unless I'm stuck in traffic. Idling it'll get to 216* and the high speed fan turns on.. Moving along @ 70mph it stays at 189* or so.

Wow, my ADM Fan works super consistant...It stays at 192 (same as stock fan) and never gets hot, never any issues...

I talked to Alvin and he said there are some things he can improve on in the tune to make it work better.

Thanks It was the first C6 Efan (we usually use LS1 fans) that I know of to work on a 07. Since that fan didn't come with that 07 computer (different from 06) in any platform there are a few bugs with my initial guess.

Different fan setup. This topic is about C6 fans. That hptuners topic is about LS1 fans.
