it turned out that my hydro fan ecu wasn't getting any juice, so i just fed a 12v wire into it and problem solved! thanks to pernilongo for giving me hand..
i finally did some testing on the rad temp sensor and there's no power being fed into it. also i tested the actual hydro pump two pin harness and there's no power being fed into the pump either, so it's for sure that my hydrofan ecu is done.

i have that exact same problem where the B+ switch pin wasn't getting any juice. i never got around to solving that problem so i just made my own relay to power the B+ pin. keep us posted on what that problem could be.

yea, the B+ switch wire came off when i pulled my avcr boost controller and ever since then my hydro fan hasn't been blowing as hard as it use to. i think that's the cause of my temp to rise.
yea, i thought about that. i might just hot wire the damm thing and have a switch for it. i'll test out each wire from the hydro fan ecu this weekend to see if i might of shorted it out.
nice numbers considering that you ran it on a mustang dyno, if you ran it on a dyno jet your numbers would of been much higher. we pretty much have the same setup and i can't wait to get mine tuned.
i have a to4 single upgrade with a stock intercooler and radiator/hydro pump setup. i'm going to try to bleed the system and if that doesn't work then i'll just replace the thermostat. does anyone know if the 2jz thermostat will work?
i know i was thinking about that too, but i never had any problems with before so im hoping that my thermostat might be the problem. its the santa clarita hill on the I5 and the 2 north heading out to la canada is when i noticed the temp rising.
