oil temp debate

indyn · 08-15-2011, 10:46 AM

hasn't SAM@GTM already confirmed that IGN timing gets pulled as per the IAT from MAF.

Look at this post GTM Stage 2 Supercharger Preliminary Testing Results.

ECU will pull timing as the engine gets hotter and heating up the intake. Thermal insulation in the form of wrapping or better yet ceramic coating should help. Oil cooler should help as well.

I think everyone knows ECU will pull timing based on IAT, but I am saying ECU doesn't pull timing based on oil temp directly (I don't think personally anyway unless someone can prove me wrong).

Isn't the engine that gets the oil temps up and heatsoaks everything around it including MAF which monitors IAT?

As per the service manual of the g37, these input parameters control the IGN timing

- Crankshaft position sensor (POS)
- Camshaft position sensor (PHASE)
- Mass air flow sensor
- Engine coolant temperature sensor
- Throttle position sensor
- Accelerator pedal position sensor
- Park/neutral position (PNP) switch
- Battery
- Knock sensor
- Unified meter and A/C amp

Agree, but that is an indirect effect, not direct. Unless you are sitted and parked, you shouldn't be soaking it anyway.

I'll try to log these temps next time I'm out for spirited driving. But have noticed that the gen 3 tubing does get really hot that's even not bearable to touch after aggressive driving.

If you have Gen 3 tubing insulating it is a must for aggressive driving. The all metal tubing heat soaks very badly compared to the insulating effect of the stock plastic.

You can see my cheap/ghetto Gen3 heat shielding post here: wstar's Journal, using DEI cool tape and some lace-up intake wrap that's basically fiberglass w/ an aluminum lining. Or you can go pro and wrap it all in gold foil or something

did some logging with Cipher and this is the last log in my spirited driving.

Don't see any relation with any of the temps with IGN timing. Maybe there is a relation between a/f ratio and timing. But check out VVEL timing and MAF values.

Were you in closed or open loop? I don't know if the car reads anything else when you are in closed loop other than A/F.

MacCool · 08-18-2011, 10:16 AM

Best way to manage concerns about high oil temps is to put a piece of duct tape over the oil temperature gauge.

EVOnomore · 08-24-2011, 08:26 AM

Just did that!No more staring at the Temp Gauge.

My buddy just installed my stillen 19row oil cooler and said it doesn't go above 180. That is in normal driving no hard driving yet, I will test that out when I get home.

wstar · 08-24-2011, 10:21 AM

I have the Stillen 19-row too, with a thermo plate. It's still possible to get just under 240 on an SCCA course, and I've seen as high as 210-220-ish in very aggressive street conditions. In both cases we're talking about in extreme Texas summer heat though. I'll be out at MSR tomorrow for their Red Meat and Race Fuel thing on a real road course, I'm sure it will be enlightening. I expect I'll be able to reach 260 if I try. If that's the case, I'll probably invest in a bigger cooler install sometime this winter, for next summer. Not enough track opportunities left in this year's heat to bother really.

I *really* hope that AM Performance does some kind of consumer release of their oil:water cooling solution, that would be even better than a larger Setrab.

Hey now this Thermo plate you are talking about mind sending me a pm on that? Not sure what that is and what it is for if I need it or not.

From Z1's Web Site:
You may choose between the Standard Non-Thermostatic Mocal Sandwich Plate adapter and a Thermostatic model. It is highly recommended that a Thermostatic sandwich plate adapter be purchased when installing an oil cooler onto a street driven 370Z. As important as it is to keep high oil temperatures under control, it is just as important to maintain the proper temperature to ensure the highest possible lubrication.
Z1 Motorsports 370Z Oil Cooler Kit

Basically, the Thermostatic Plate Adapter allows you to use a thermostat to bypass the oil cooler in winter months on the street so that your oil can heat up to the proper operating temperature.
