MSX 150 / MSX 110 DIY ECU Reflash?

[Mike Greenwood]

It looks like I stirred a pot that someone else is already knee deep in! Hyperco, I am buying a fresh Ecu from a member here. If it would be better suited in your hands, I would loan/sell it to you.

I appreciate the offer, but I have enough ecus to play with.

Here you have the files from the polaris ecu

My tuner give a look at your files but he told me that you never read good the 29f400, file must be 512 kb.

Someone have a dump of the 29f400 flash?

[HiPeRcO]

Not yet. Need to pull one off the board and read contents offline I guess...

Hi , sorry for being absent for so many days . I was very busy in my job . Regarding the eeprom reading , you need to remove it from the pcb in order to read it or try to shortcut the pins on the cristal oscilator.
Regarding the 29F400 , i already removed the chip from the ecu and connect it on one peugeot ecu witch was ok for reding the content of this chip. Unfortunately i get exactly the same result as i get it on the polaris ecu . I don't believe that a standalone reader will give you different result but we need to try this option as well .

May you read it with a Willem programmer? Flash size is 512kb, the reading must have the same size.

I made a reading of my ecu, here the file: http://www.mediafire.com/download/2b...150_29f400.zip

Excellent!! 512K file size, perfect! How did you read it?

Now to find out how to interpret it...anyone have any tuner buddies?

[Tony2k]

Flash desoldered and read with Willem GQ-3X.

Now I'm waiting for an answer from my tuner!
