chadz34 Posted July 17, 2011 Report Posted July 17, 2011 Hey guys, just wanna let my Z34 run a little cooler seeing as how it's strictly a summer car. If I change the 195F thermostat out for say a 180F, will I have to send Ben my chip for a retune? Or, will the car pick up on it? Thanks! ChadZ34, 92' Lumina Z34 56,000km. Quote
RobertISaar Posted July 17, 2011 Report Posted July 17, 2011 the PCM only knows what you tell it, it will not automatically compensate for a different thermostat. Quote
chadz34 Posted July 17, 2011 Author Report Posted July 17, 2011 Screw it then. Unreal the heat this car makes, the LS never ran so hot, but I tossed the 180F stat in it, and it picked up on it instantly. Only runs a quarter temp. Quote
AliasCT Posted July 18, 2011 Report Posted July 18, 2011 The T-stat is a mechanical device, the PCM will only know that it's running cooler. However IMO a Ben chip (WOT-Tech, right?) would be worth it. He sets it to command the fans on earlier for more consistent engine temps. I've been debating it for a long time now simply because of that! FYI, when I emailed him about whether I should drop the temp of the T-stat he suggested that it's not "necessary" unless you're running performance mods (ie. you expect the engine to run hot when moving). The T-stat will only keep your engine at 180F when the car is moving... Quote
