If you just look around the web info to make your own isn't that hard to find. All the old V8 belt driven cars switch to electronic at some point and have to make a system.

 

I was already beating him up on saturday nite about this..

 

Not at all. This kit is not simply a toggle switch, it is designed to only operate the fans when the operating temperature has exceeded the switch-on point. No monitoring of temperature or input is required from the driver.

 

The kit replaces the factory relays so if there were a failure simply remove the new relays and reinstall the factory units. Gentlemen keep in mind, All Mazsport products are tested in multiple vehicles in different enviroments and installed by various users before release. This kit for instance was being tested in Chicago,North Carolina and here in Florida more than three months ago, there have been no failures at all or we would not have released the product. As always, thanks for your support,Scott

 

Sorry my previous message might have confused you

i was actually asking whether the relays you got on your units can be replaced with normal factory relay(attaching the wires to the factory relay) if somehow they get faulty/blown, or are you saying if the relay get blown i wont be able to use the unit anymore?

the reason im asking is that i had the factory fan relay blown at one time

thanks

 

A toggle switch is cheaper yeah, BUT if you're not in constant high heat weather then you need some way to monitor your coolant temps in order to turn those fans off. So either you have your canscanalyser hooked up (pain in the butt) or buy a $150ish coolant temp gauge. In the end the largest part of the market (climate region) pays the same amount of money, but those with one solution have to monitor a gauge.

 

or you can just buy a adjustable temp sensor kit from summit, jegs, etc. for 60 bucks.

 

Is it absolutley necessary to buy a tempt gauge with it?

 

Absolutley Not! This kit will monitor the water temperature and modify the fan speeds as necessary to maintain a cooler running engine. Scott

 

Thanks Scott, just ordered it last night. Am very excited!

 

Here is when this mod tickles me, and I am female, so I can get away with saying "tickles"

I walk away from my car after driving around in 90+ temps and I can hear the fans turn off before I walk away.

I have to tell you, it always bothered me when that fan would run a long time....

 

This will make it run longer.

 

In regards to the fans running after shutdown:So which is it? My though is, if the engine is running cooler to begin with, it won't take as long to cool it down after shutdown.

Personally, coming from a '67 GTO with an electric fan w/toggle switch, it was second nature for me to flip the switch when I started the car. Problems arose when someone else drove the car and forgot to flip it.


MM: Still waiting for a How-To for my toggle switch! Thanks in advance!!!

Because the fan is running more while the car is on, the temps are going to be lower than they otherwise would be. When the car is turned off, the fan will run till the car is cooler than it would be stock, but because it's already been cooled earlier, it might not have to run as long.

 

Mazsport scott,
would this unit be compatible with our Australian cars? There appears to be interest here as temperatures can get quite hot?

The thing I found Most interesting was this:





Perhaps it would work the other way around... Ya know?! Put an MX5 engine in our 8...?!

Then I could be a P!$$'d-off Piston owner...

 

Exactly.
However, it takes coolant longer to go from 200° to 180° than it does to go from 230° to 200° in the same ambient situation.

 

Yes this unit will work for all RX-8's.

 

if the temp never gets above 195 deg and runs at 185 most of the time.. the fans go off real fast...

this is a na observation...

beers

 

did the install tonight, took about 15 minutes. The instructions are of wordy considering you are basically doing this:

1) cut coolant hose
2) plug in sensor, tighten with clamps
3) connect grounding wire
4) connect two plugs into fuse box (driver side front of the car), making a small cut into the fuse box lid to allow the wire to enter.

Pictures would have made the instructions clearer, but I was able to do it without them...

didn't get a chance to play with it much. And I no longer have a canscan on the car, so I can't give anyone numbers right now.

 

Created a Pre & Post Installation Page with Photos of how this product looks once installed. Please go to Photo Page to view.

Mazsport staff has done all the hard work for you to make our unit plug n play, (this is not a toggle switch) With No Monitoring Required

 

The way I see it this mod eliminates the PCM from controlling the fans by turning them on let say at 10 F lower engine temp. And since the PCM has no control over the fans we are loosing the low-high fan speeds.
Wouldn't be cheaper and OEM looking if just replace the ECT sensor with a one with appropriate temp/resistance relation that will trick the PCM to think that the turn-on-fan temp is reached, but actually it is 10 F lower?
I know PCM uses ECT sensor input for calculating fuel and timing at some point, but would it make that much of a difference?

 

Yes actually it would make a HUGE difference in the way the vehicle ran. The fuel maps (especially warmup) would no longer be correct. The factory ECU works in conjunction with this kit to operate the fans, we have not eliminated ECU control.

 

Can you elaborate on that?
How the PCM controls the fans when they are already forced full speed on by your mod?
Am I missing something here?

 

The fan control is now an OR situation with the two inputs being either the factory ecu or the signal from Scott's system. Either system can now start the fans, but both systems have to agree to stops the fans.
