Hey sup guys ive noticed that when driving my car "spirited" (g37 sedan 6speed) on a cold or not completely at fully warmed up temps, that my engine is a little bit more repsonsive on the throttle noticeably at the lower rpms like 3k up? Ive tried reseting the computer with the press the throttle 7 times trick and still the same result. Has a faster throttle response and more aggressive acceleration to redline. I has a mishimotor thermostat and am wondering if this mod will keep this characteristic with the engine

 

*just a theory* Its possible that since your engine is not fully up to temp your air intakes are not going breathing as much hot air from the engine bay. No different then your car will feel more peppy on a cool fall day then a 100 degree summer one.

 

Good point, i was also thinking maybe the car runs on a different map setting when not fully warmed up? Either way a tune is in order and ill see what comes about after its done

 

Temperature, Humidity,and barometric pressure are all factors and affect MPG as well. Temperature also affects tire pressure as well.
