What Does It Mean To Reflash Your Ecu? Thanks For The Response

[dread]

It means to update or change the program that controls ignition timing, air/fuel ratio's, boost pressure and a million other things.

you can say that again!


our cars (and most others I presume) have what is called non-volatile memory. It's flashed and stored. When re-flashed, the old flash is lost.

how do you do it and any benifits?

[knowledge007]

Yes, not sure when you p/u'd your speed3 but there is a reflash for the ecu available for our cars. This would obviously be done at the dealer.

[SwampAss]

there is a reflash available for *some* MS3s. It's dependant on VIN.

can only be done by the dealer and yes there can be benefits to this. Mazda will release periodic "updates" to the ecu which have to be flashed in order for the change to take place. This is done if they find a better way to control the vehicle's ignition, timing, air/fuel ratio, etc.

Once they release hand held tuners we'll be able to flash these ECU's. I can flash my Mustang's all day long from the comfort of.... anywhere.

I flash highschool chicks.

I flash highschool chicks.

With what? They told me they couldn't see anything.

[SwampAss]

They're telling the truth. I'm hung like a light switch.

[Vixen]

LOL! At least you are an honest flasher.....you don't see those everyday!!

[matsuda]

No.

You can reflash your own ECU with any J2534-1 compliant OBD2/CAN interface.

well why didnt' you say so I have one right inside here...(godown)

DiabloSport Predator I presume? Very slick interface and amazingly simple to do. I'm surprised nothing of the sort has become readily affordable and available to the Mazda community yet.

Yep computer chip with data. reflash = data is erased and rewritten

I have a 2006 Mazda 3, purchased last August; does anyone know if there's an update to the ECU for this model?

Short answer... maybe. The only way to know for sure is to take your car to a dealership service center to check the VIN against their computer. Naturally, you'll need to approach them with a legitimate 'problem' for them to hook it up. They'll tell you to go away if all you ask them is check for an ECU update. An acceptable excuse is that your check engine light came on.

[magik]

Thanks eddienyny; I'll try that :)

[voiceKoil]

Whats up bro, basically its like when you load windows on to your computer with an update, same thing for cars, its changes whatever the update is you want on it, being stock, stock upgrade/correction, or aftermarket. I dont want to beat this in the ground though... (five-0)
