Good job.

how can you read data from ECU?

This ECU file stucture is vey simmilar to other MMC ECU.
I've found Rev Limits and Speed Limits first.

It's no speed limits? ;-)

and 6700rpm cut.

Very well done!!!
I know that Colt CZT uses CAN-bus (please correct me if I'm wrong), so it must have been a bench trick

.
Now let's see where the maps are and make a good xml file for it...

Must've been fun desoldering the ECU connector.... what's the story there?

Broadly speaking, looks like maps start at $50000, and go through to about $57FFF or perhaps $587FF or there abouts.

There's a lotta code in this ROM for a little wee engine...!

Hi @ all, the flashing of the MH8105F is done.

MUT-III uses a mix of K-line and CAN-BUS for Diagnostics. Engine is K-line, stuff like airconditioning is CAN. I only know cause i had to get the lastest update for my diagnostic scanner so i could fix the trans, and Mitsubishi laughed at me when i said i couldn't get in and told me that was why. So got the latest update and CAN interface and I was in. Turns out I didn't need the CAN interface for Trans or Engine. Unsure about reflashing it though.

Has anyone identified the micro yet? MH8105F is an internal Mitsubishi part number/cross reference; who's chip is it and what is it?
I believe it's either ST10 or Renesas, not sure the exact variant. 512k flash.

If Kline is present for the engine's ECU, that should be enough to reflash.

MH8105F is just the part number for mitsubishi.
Perhaps it is an SH microprocessor, just like the rest?

This presumes that the bootloader / ROM allows you to upload a kernel over KLine. It may require you authorise over CAN.

I think it's m32r cpu, uses Kline and 16v to boot.

Cheers!

Is there any way to read this flash and copy it over into another ECU ?

by **Marmes** » Fri Jan 11, 2008 3:47 pm

I think its possible

Yes it is possible to copy complete dump to one other ecu.

Right now we done more then 100 Cars all arround the whole world trough our dealers.

On the colt CZT 1.5 i see just 4 different stock dump.

It is also much similary the FourFor Smart 1.5 177HP.

Trough our device is also lock the file inside, so can't read it anymore other then us Headquarter.
