I need ecu map of MCS(oem ecu), 2002 to 2005,
Does anyone have it?
I need it for installing HKS Turbo Timer and Apexi SAFC...

Thanks for answers

 

Try a Stand alone system if your going with a Turbo.

 

Installing a Turbo Timer doesn't necessarily mean your running a turbo. It just keeps the car on for a set time after the ignition has been turned off and the key removed/car locked. It's meant to cool down the turbo/engine after a hard run without having to be there in the car...

 

Thanks for explanation, "Chris" thinks that only he is wise....

Im already looking for ECU map...

 

by ECU Map you mean a wiring diagram correct? You'll prolly have better luck PMing Tuls, Fireballed Brian, or some others as they experience with the S-AFC.. Good Luck.. let us know the results...

 

Weird, I thought I posted a reply to this yesterday.

I have the ECU pinout guide for the safc at my home computer. I will try to remember to post it up when I get home.

For your turbo timer, there isn't really a pinout but just pick the proper wires from under the steering wheel.

 

rhubbert, thank you very very much.
I'm waiting for your post ..

 

The radiator fans will run after you take the key out if the engine is hot. If it's not too hot they won't run even if the car is on. I think that you'd do better with a fan controller set to lower temps. You could run this through a turbo timer to get the effect you're looking for.

Oh, do you need wiring diagrams for the ignition too? I know a site I should be able to pull that from. I could get the engine ciruit too, but that's much more complicated to look at then the pinout at home.

 

Starting Circuit


Immobilizer Circuit


Cooling Fan Circuit (Single Stage)


Charging Circuit

 

Yes rhubbert i need them too, thanks for everything rhubbert i trast you

Dr Obnxs, Radiator fans only cools the motor block BUT turbo timer just keeps the car on for a set time after the ignition has been turned off and the key removed,car locked,it means resting motor and other components
And attach this, HKS turbo timer measures 0-100km/h, 0-400meter, digital km/h, shift light bla bla bla

 

Power Distribution

 

ooooo thank you rhubbart, u r number 1

 

And for the Grand Finale...

 

Woah, nice call rhubbard i'm sure this will help several people out cuz as far as i know there aren't any pinouts online.

Dr. O.. like erkin said and like i said earlier. The turbo timer keeps the CAR ON, in idle, so it allows the engine, supercharger, etc. to cool down. The radiator fan just cools the block down. It's different....

 

The SC won't "cool down" when spinning. It doesn't work that way. It will still create friction and heat. There is some benefit to letting the car run on a bit if you pound it hard and then shut it off, but not much. If you just let our Minis idle, the fan will cycle on and off, and I've found engine temps that are higher than during street driving.

There's a reason they're called turbo timers!

Matt

 

So, rhubbard (aka the guru!): can you tell me what the output from the OBD-II that the ScanGuauge shows as Ign Timing means? It's a number that ranges from 2 to 50 approximately, and is around 35 while cruising on the highway at 70 in 6th.

thanks

 

degrees of advance. The OBD-II values should be scaled unit, like temp in C or the like.

Matt

 

Turbos are still spinning while in idle as well. It will benefit in terms of longevity. Whats better running your car and then coming to a stop and turning it off, or running then letting it run for 2 minutes at idle then shut it off. A brief cool down period is ALWAYS better for the car... Period.

EDIT: Sure the supercharger is still spinning, but at idle, creating A LOT less heat than when its at say 3000rpm cruising speed. Being that it is creating less heat at idle than while cruising, it'll allow the temps to drop and thus "cool down" the supercharger. To me it just seems like such a simple concept...

 

Thanks for the compliment, but I am no expert when it comes to ECU electronics.

As far as I know the OBD port outputs in CAN BUS or something along those lines so it's not as simple as 1 one wire that has a certain range of voltage outputs to determine a sensor signal.

Timing is measured in advance and retard and if the range is from 2 to 50 then I can assume (don't know for sure) that 0* timing would be halfway. Using that idea, at cruise you are at 13* advanced.

This is all just a thought, I have no idea if any of this is correct.

 

I got the SAFC pinout from a post when I was searching SAFC for fun one time. Every thread I saw told people to search and not a single one actually had this, so I knew it was worth saving. When I get to work I'm gonna double check that pinout against the other wiring diagrams online.

 

Cause I'm sweet here's the wire color too. (2004)

Knock: Yellow
Throttle: Red
Ground: Where ever you want.
Pressure: Yellow/Violet

Not sure on the other ones but RPM from the coil is either Black/Red (or Black), Black/Blue, and Red

You're just wrong here. Look at the Eaton graphs. The temp rise is constant for most RPMs until you get over 10k or so SC speed. At 3000 RPM on cruise you're off boost, with a free-wheeling SC spinning at a bit over 6000 RPM. While this does create some friction, it's not as much as when the thing is spinning faster under boost.

The turbo timer was implemented for one perpose only: to cool the center hub assembly on turbos because they can pack a lot of heat (remember, they get hot exhaust gasses to spin....) and this can degrade the oil if you shut it off hot. There is no analogy with the SC. All heat in a supercharged car is dealt with via the radiator and air flow. Neither of which is in play at idle at rest.

While the concept seems simple (adding a turbo time to cool an SC car), it's not sound. You'd be much better served learing how to treat a car after it's been driven hard than to rely on a tool used for something other than it's intended function. If you really want to cool the car after shut off, wire a delay relay to run the radiator fans for a couple of minutes after the car is turned off. That actually will cool things down.
