lol, the 7202 is so mid 90's
Yes, you're absolutely right. Dmitry, is the gyu (in Moscow) who has done re-flashing to us (vr-4.ru) members (not all, but few). One of our mates, had purchase the modified in japan ECU (I'm not quite sure, which ECU it was MINE's, PROS's or something else), and decide to share it with us (of course for some money). The ECU's as Valmes said, had Speed Limiter cut, the boost are at about 1 bar, and has the same maps of ignition and fuel for all four types of those maps (A,B,C,D) (A and B map types are for manual trans, and C and D are for auto trans). Firsts of all, after re-flashing, there was appear some damn sort of knocks, cause our fuel are not so good, as japaneese. And the ECU's are not goes onto safe mode, cause it's not present. So, after that it was decided to go to the DYNO and tune that modified ECU to fit our damn gasoline.Originally Posted by AderC
what formats are the maps in.
Spoke to the boys at work and they think the could do it for me and price for the programme to do myself
If i had pre and post ecu spare they would try to copy the across the programe

No longer a VR4 owner
vr-4 ecu was re-programming, here in moscow.
Old and New, and also, VR-4 ecu's have 3 verstion,
the first 1996 - , with processor MH7201FS(MR16Core)
the second a middle 1996 - 1997 - processor MH7202(H8/500Core)
and third 1997 - , MH7202(H8/500Core)
the last 2 version is absolutly interchangeable.
our MMC ECU guru is made with our club on stand a new fuel map table, cut speed limiter, and hight rpm limiter , new program is more evil then stock, our tunned program boost up 0,9 atm))), but offten trap to safe fuel map table, because fuel in Russia, still not like europe (japan) quality
was LHD Legnum VR-4 Type S, 0,85 kg/m now , 4WD, AYC, [winter drift car team]
was RHD Galant VR-4 MT, no AYC no cry
was RHD Galant VR-4 GTR N1, ring racer, 407 hp
JDM EVO 7 GSR
Radical SR3 RS
ooops sorry for flame
admin please delete my messages, they just copy Valmes posts
Cool. So once Colby finally releases the H8/500-compatible version of ecuFlash we'll be able to flash our ECU's...

At work they recon they can do it NOW if i have another programme to put into it
but it would entail removing chip from board which they do all the time.
We was chatting about piggyback ecu's etc the other day and he said no ecu is un mappable it is how hard they are to do, and said ours is know different but it is knowing what each bitmap point does
There's some progress on the ECUFlash front. The latest version released a few days ago (v1.3.1) is now capable of reading (but not yet re-flashing) the VR-4 ECU (H8/539). I've just connected my tactrix cable and downloaded my ROM successfully. Re-flashing is still work in progress.

Copy of my ROM here if anyone has EcuFlash and wants to play with it.

Following some gratuitous Babelfishing I've registered on the vr4.ru site and located the thread on ECU reprogramming. I downloaded the XML definition files that are needed for ecuEdit to read the maps and settings in the VR-4 ROM. I've loaded the settings and my ROM into the software and I can now edit stuff! Screenshot below:
All we need now is the reflashing of our ECU's to be enabled in ECUFlash and we're in business...

Very interesting Ade - Now, on that fuel map, is that as it was loaded from your ROM?
The reason I ask is that if you look at this thread at the AFR charts:
http://www.clubvr4.com/forum/showthread.php?t=24407
My chart (7th one down) and L6's chart (3rd one down) are FAR richer than that chart (assuming that 100% engine load = WOT on the rollers) - and we are on a standard ECU with no fuelling mods. I don't know about Tim, but I had a tankful of 99RON petrol too.
Looking at my own chart, by the time it was at 5000 rpm, it was so rich the machine couldn't read it. Tim's is similar - Your chart shows a target AFR of 11.4, whereas the result for tim was about 10!
just to add to this I had Pooo 96 RON on this run
One day I'll get to do it again on proper 99 or higher.
at the time I thought I would go for the lower to find out my minimum output
TimM
Mods section-- Mod No1-Clifford Inteli 950 with remote start and Pager225x40xZR18 Good year Eagle F1's More to follow!!
I wish I could make head or tail of these charts
I can get to grips with AFR and those 3D graphs look the dogZZ B's
I need some schooling are there are informative websites I ve looked at inovate in the US and watched the Vids which are pritty cool but are there any books etc?
PS sorry for diverting the thread .... Back to the ECU flashing
Normal service is resumed .................. LOL
Kieran - yes it is from my ROM. There are 4 fuel maps in there - I just picked one at random to show a screenshot. Could yours have been using this one as the target AFR dips below 10 at 5000rpm:
Also not sure why the Load% should be 0-200 rather than 0-100. I'm assuming 200% is WOT.
aDe
the interesting thing would be to figure out how it uses those fuel maps. I'm willing to bet it is to do with the knock value the ecu senses.
aDe, could you please post a link or upload the XML definition files for ecuEdit you got from vr4.ru .
I've just purchased a cable and software and want to get the tables out of both my standard ECU (facelift VR4 tiptronic) and a my Blitz modified ECU to do a comparison. Want to see exactly what Blitz have done to the fueling, if anything.
Cheers.
Copy of the ecuedit XML definition files here
Unzip the files to your c:\program files\ecuedit\XMLDefs folder (back up the originals first!) then EM2005 Galant VR-4 should appear in the list when you click on the File...Open ECU Description menu.
Can't take any credit for these files - big thanks go to the guys over in Russia!
aDe
Nice work Ade!
Have some rep. Once you succeed in flashing the ECU with a better config, let me know and I will come and visit!
"With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead."
I've posted on the vr-4.ru site asking whether we may be able to get a copy of the software they've used for reflashing (I have a copy of a tuned ROM file with raised boost and RPM limit already)
If I get hold of the software we'll need to get hold of a "spare" ECU for testing purposes as there's obviously a chance of things going disastrously wrong and ending up with the slowest VR-4 in the country...
aDe
I'll source a spare ECU! I know a man who has a couple!
