fan temps
fan temps on wed, i used a buddies scanner with live run and tested (2) different pcms(vendor tuned both pcms). the engine temp went as high 252/253 degrees. the electric fans never came on. just to update, i have to send both pcms back to vendor, to locate the problem. im thinking steve@frost and cut my losses(many problems with harness?pcm). or maybe just have the vehicle dyno tuned and have the tuner fix this problem. this is possible, rite? all mail order tunes must be recalibrated once everything is situated in vehicle, rite?looking for feed back. thanks.

Wow, did the engine temperature really go that high?
Above 230F I start getting nervous. Maybe these engines can take 250F, but that would scare me.
Good luck.

If coolant is 230F, then oil is @ least 260F+, more likely 280F. Regardless, LT1's, IMO, aren't as wimpy toward higher engine coolant temps, as are LS1's. The stock rings in my LS1 & LS6 short blocks have lost their sealing ability @ 245*F (coolant temp); lesson learned. I only use "Hellfire" rings now so that if she gets hot, I don't have to re-ring the pistons.
