Took the hawk to work today and noticed that the temp in stop and go traffic hit around 220-230 on the dummy guage. I tried the old trick of turning on the AC, even though there is none, but to no avail. Temps still stayed high.

What's the stock PCM set at for the fans to go on?

226 is stock settings. Maybe bleed the coolant a little more?

mine was around 190-200, my tstat is 160 though. agree, may need some more bleeding. what was set on the pcm for fan on/off? I set mine to 205 / 215 if i recall.

180-200 with the AC on in stop n go, that’s with the 160 t-stat and the fans kick on early

180-200 for me as well with 160the and early high speed.

Ok then this makes sense. I was getting a little nervous but it never went above that from what I could tell.

Will bleed it and see if that helps. Brain at Kaltech did a basic tune just to get it running (the pcm was programed as the engine was being built) so I don't know if he changed the temp settings.

Monday is dyno tune day so if it needs to be changed so be it.

Never got above 195° with ac on in a recent trip to lake havasu where it was about 112-115. Also have the fans coming on early. On a normal day in cali in stop and go never gets above 180°.
