Tuning My Ownecu

[Crans]

Hi,

I want to learn the basics of remapping a car. I have an r32 GTST. What hardware/software do I need to buy to to remap my ecu.

I really want to have a play and learn more about my car.

I have a friend that is experianced in tuning some other type of cars that will give me a hand.

And before you say dont do it you will blow it up,, I really dont care if i destroy the thing its a toy.

[Toasty]

you are definately game, but i do remember reading somewhere on this site about tuning the factory ecu which has links to other websites. or it might be on nissansilvia...

go for it!

Mate there is nothing game about it, you will need an eprom burner, and datascan. A consult also helps. If you can get a wideband a/f meter it also helps, but as long as your car doesnt have any problems(such as fuel pump) then its not absolutely necessary. My first remap was on my Z32 tt. The A/F ratios are calculated in the numbers you enter into the appropriate rom addresses. We entered 12:1 afr for the full power load cells, and took it to a dyno day- result exactly 12:1 afr under load. There are a few programs out there, and many of them are freeware.

If you want to keep changing the tune, burning EEPROMs and changing them will become tiresome, so you could try;

Yep, these look the goods, i didnt know they were finished, and will now get one for my gtr(maybe we can do a deal for a few)

[Crans]

nistune sounds pritty good.

Only problem i can ee is the lack of rb35 support as in the future i wanna put on in.

Can the rb20 ecu run the rb25?

[Adriano]

Can the rb20 ecu run the rb25?

Sure can, just use the rb20 fuel, ignition and sensors(although these can be upgraded versions of course)

You sure about that? I'd definitely invest in a wideband O2 sensor for tuning and make sure you hook up some sort of knock detection as well.

Yep, sure. If your running a stock AFM and injectors, then the cells for load are entered as the hex value of the afr you want to run, but would definately agree about the wide band. Knock can be monitored by consult.

But stock afm/injectors are almost 20 years old now, surely it'd be risky to think they are still working the same as when they came out the factory?

He ran it on a dyno and verified the result, so there's no much room for doubt.

Knock can be monitored by consult.

I have a consult interface and have datascan and ecutalk - neither of which show knock. Do you know of any consult software that has knock reading? Datascan can monitor arbitrary memory locations, so i assume if i knew the location i could read the sensors output...

[Crans]

Where can I get the required hardware to hook my PC up to the consult port?

[sewid]

I have a Consult -> RS232 (PC serial port) cable for sale actually. I used it when my ECU was standard but no longer need it since my ECU is no longer standard.

It's $100 including the Nissan Data scan software license that came with it. PM me.

[Crans]

Dosn;t sound too bad.

Where is the actual port in the car gotta make sure its there first?

[sewid]

It's in all R32's.

It's probably under the dash on the drivers side.

[Beer Baron]

yep, remove the fuse panel cover. it's in there.

[Crans]

Cool ill have a look on my lunch break

Im planning on running an embedded intel Xscale computer system.

Running windows CE indash touchscreen. System boot time should be all of 5 seconds

Anyone used the INNOVATE MOTORSPORT ST-12 with LogWorks ?

Anyone have any experiences, good/bad ?

Everyone who drives these cars assumes they are still working the same, the factory doesnt tune the management to allow for things wearing out. Injectors and AFM tend to fail rather than lose performance, the only exception is injectors which if never cleaned can become dirty(although with modern fuels it doesnt tend to be a problem, there are plenty of cars with 300000k's with the original injectors.
