Finished hooking up black box last night, a tapped oil cooler outlet alluminum spacer 1/8 npt to get accurate oil temp, ran about 2600 unloaded on trailed for about 5 minutes temp went up to 180 degress so decided to put aftermarket oil cooler on, my rpm isn't matching tiney tach no mater what I set it to so will have to try resistor plugs. Question <<<< what is max oil temp you recomended or shouldn't go over.
