Russian ECU software

[wintertidenz]

Has anyone actually looked into this site?

They report that they can flash MH7201's.

Unfortunately you need to wait for the hardware key to arrive in the mail before you can do anything with the ECU, by the looks of things.

could there be some difference in the ecu?

MH7201F _ ( 128k ) - from 1997 Space Wagon 2.4 GDI; Galant 4G93 GDI; Mirage Dingo 1.5 4G15 GD

[Nutter_John]

I read that as well Ash , be interested to ask the question if they support the mh7201 from 1996 - 1998 onwards

Price wise they offer the hardware out at around £140 but it also doesn't say if they have created the maps to allow you to alter the ecu image

I use this sw and flash MH7201F fine

[wintertidenz]

Did you flash a 7201 from a Legnum, or another car?

[Nutter_John]

That was going to be my question as well Dan

I purchased a copy of this a month or so back, it does not read our 7201 ecu's, I have been in touch with one of the developers and he is willing to have a look at adding support for our 7201's and has sent me an address to send the ecu to.

I have been slack and not sent it off yet but I will, I imagine there will be no news on this front for at least a month.

The developer did send me an older version of the software that was what was used when developing the 7201 support but still no go, the ecu they developed on did not appear to have an external flash chip.

I was just looking at the same stuff and funnily enough came across your posts on their forum Pierre, then I came on here to send you a message asking if it got sorted and look you've already posted up where it is up to.... Funny how things time themselves.... Let us know how you go!

[pbaron]

Bit of an update, the russian developer got the ecu I sent and has advised that he has added in support for our 7201's. I got an updated version of the MMCFlash software yesterday with support for this built in, I dont however have a 7201 ecu handy to test it against.

The MMC flash software is just for reading and writing the image to and from the ECU, they do not provide any definition files for working with the image in ecuflash etc.

I will post another update after I have confirmed that the latest version of the software works ok.

[wintertidenz]

PM sent to you.

[pbaron]

And replied to.

[Shtiv]

Oooh Keep us up to date!

Further update:

I have used the updated version of MMCFlash combined with OP2.0 cable to connect to the 7201 ecu in my brothers pfl leggy, and read the image from it. I then wrote the image back to the ecu without change, the first step in the write process is to clear the flash rom, this had me concerned if the write failed. The write however succeeded and the car started up and ran so all must be good.

So, for anyone interested, the Russian MMCFlash software version 080 with update 2 is capable of reading and writing our 7201 ecu's.

I purchased my copy of this from Hamish at Evoscan with the dongle taking a week to arrive. It looks like they provide a copy of the software tied specifically to the dongle issued to you. When I got the updated version from the Russian developer he needed the license number from the dongle.

This software removes the risk associated with removing the flash chip from the 7201 board and socketing it back in.

Work needs to begin now on working up an open xml definition for the 7201 ecu. Can anyone advise if the 7201 is similar in operation to any other mitsi ecu that has definitions available, or failing that know of a disassembler for this code.

Awesome news! I'll still send that ECU down to you Pierre.

I've got a copy of Kinky's original 7201 ECU dump around somewhere, before he figured out how to flash it. Let me know if you want it.

[foxdie]

Hi Pierre,

Where can we get this MMCFlash software? I found something on EvoScan.com but it's hundreds of dollars, hoping it's not one in the same.

[wintertidenz]

Check my first post up the top :)

[foxdie]

Hmm, to pay £130 to be able to reflash 7201s now, or to wait for EcuFlash to add the functionality.. :)

[lateshow]

Hey can someone post rom from a7201, id prefer auto, so that we could see if there's some difference. :)

[phosty]

They're all ready posted on here (includes ROMS and xml files from ECUedit):

Note that some of the address have been updated since that time as per the EM2004/5 (7202) ecuflash xmls as they are not all correct. But it's pretty easy to find the tables in the 7201 roms as most of the data is the same as for the 7202s - just search using hexedit or similar. I think you'll find that the word length axis tables are stored in little endian format so they are not quite paste and search from the 7202s (but easy enough to convert).

Actually it's cheaper than a £175 Openport 2 dongle as required by ecuflash if you don't already have an OP2 .....

[Nutter_John]

Dont you also need the obp2.0 cable to still program it or do you get an cable with the 7201 software and dongle

[phosty]

Ahh - you might be right John. Evoscan website says it 'Supports OpenPort 1.3U and OpenPort 2.0'. If a 1.3U works then maybe a cheapo modded VAG-OBD cable might work?

[Nutter_John]

would think that the generic cables wont work as they don't have the adaptor you plug into the white socket

going to order a copy of the 7201 flashing stuff though so will try all three cables when i get it

Thanks, just wanna see if there's any difference with boost control/ignition in the 260 hp model :)

[Nutter_John]

ignition is the same , boost control is slightly higher but the table is already in all roms

[Shtiv]

Well doesn't that make life easy! No more hunting for 7202 ecu's

[Shtiv]

Just posted this on OZVR4, apologies for the double post but it happens with important items.

OK so a bit of news (good news)

My H8 ECU could not be flashed with ECU flash, I double checked this today, could not read or write to/from the ECU in any way.

Today the H8 was successfully reflashed with MMCFlash and calling the ECU a 7202 as we all suspected.

The ECU ID was an EM2004 and the definitions as far as I could see matched the 7202/03 tables for EM2004 ECU's. This is great news as it means we don't have to develop brand new definitions for H8 ECU's.

I first dropped at 2500RPM limit on and that worked.

Then dropped one of my 7202 tuned maps on and that worked also.

Then I dropped the latest maps I'm using in my car including the kenneth mods and they work too. So I think this means a H8 is slightly more desireable than a 7201 as I don't think you can change the ROM on a 7201 to 7202/03 code (I could be wrong on this)....

The interface is a little slow, taking about 100secs to flash vs 10secs for ECUFlash but I'm sure we can all live with that (although a 512k ecu would probably start being frustrating if the time is proportional to file size).

So anyone who has a H8 ECU can now be a happy camper!

Oh someone noted that this software erases and then writes and this worried them, ECUFlash does exactly the same, get some things wrong in your xml and you'll erase and not write

[blodeaxe]

If you can locate any of these cars can you please download a few GDI ROMs and post it into my GDI thread I cant download any myself

4G93

4G93GDI Turbo

or for any GDI powered car you could find.
