Versa Tunes recomendation (Fan temps and Idle rpm)
Posted: September 3rd, 2021, 7:21 pm
Hello Versa Tuner team.
I have one proposition to implement in to all of your mazda tunes as this is something that is damaging to the engine on a stock ECU settings, and a lot of engines have been lost do to these particular setting that I don't se you have adjusted in any of your prebuilt tunes.
Primary fan temperature (oem 97) advised to be 85C to 88C
Secondary fan temperature (oem 101) adviced to be 90C to 95C
Idle RPM. (oem hot coolant set at 790 to 810 depending on the map referenced)
Because of the construction of the oil pump, the oil pump doesn't have sufficient flow at lowest idle RPM.
For series 1, the oil pump only starts really pushing fluid above 840RPM (new) below that it is beyond its design operational limits and barely has any pressure to the engine to switch the oil pressure sensor. (I cannot find the flow graph anymore to reference)
For this reason it is highly advisable to run idle no slower than 850RPM and recommended to keep it at 900 rpm.
I hope other rx-8 owners with expertise could chime in and confirm/deny these statment but to make your pre built tunes all that more appealing.
