VR4 Successfully Flashed

[raph]

So ,only the 1998 vr4s are ecuflash flashable then? 7202 roms, and the later 200ß models use the 7203 and are not flashable yet?

[elnevio]

What you really need to do, is read this thread: http://www.clubvr4.com/forum/showthr...highlight=7201

[Legnum]

Are there any changes in definition files (vr4base.xml) and is it possible to update files in this thread?
I found a post in geekmapped where "*Boost Cut Load Limit" was moved from "12228" to address "11d1b"?

[Atik]

Dont quote me on this, but that sounds familiar. When Ben was remapping my car, he found that the boost cut limit address was incorrect. He moved it to another location and it has since worked fine.

I *think* this might be the same problem, but as I say, I dont know enough about this to advise you any further.

[Nutter_John]

yeah it is Atik

[Legnum]

Correct address for boost cut delay is 10378. I have tested. I'm not sure if boost cut address is 1153c, but delay address is enough for me.

Hey guys, I need your help!

I've got a 7202 in my automatic Leggy 2000 model and I'm looking for an xml file for it... please forgive me if it's a stupid question ;-)

[Patryn999]

Hmmm, starting to wonder if it'd be wise to start a thread with latest definitions/stock ROM's and info. I've noticed in my searching that there is at least 5 different boost addresses given, all claimed to be working. Such as:
1153c
12228
11d1b
114b6 (Manual only)
114a6 (Auto only)

Of which so far none seem to have worked for my pfl 1997 7202F. I personally would like to get my hands on a couple of stock roms (both 7202 and 7203's) to see if I can nut out some differences, or alternately if you can flash ROM's into either processor.

Also its very hard to determine which .xml definition file is newer, and painful having to read through 13 (on OZVR4 its up to 30) pages to find whomever has posted latest.

That would require someone with a bit of knowledge to upkeep it though. Don't know if anyone is willing?

EDIT: A sticky thread to be exact

[TomTom]

Definitely agree, those threads need a good clean or good stuff separated!

Anyway, I'm still in the need of the xml file for my Legnum =)

[Nutter_John]

which xml files have you tried tom

[Patryn999]

Tom, I think you need the VR4Base.xml and the 2381003 files in the second post in this thread. To the best of my knowledge the legnum and galants are the same ECU.

Then put both in the folder (off the top of my head so may be wrong)
C:\Program Files\OpenEcu\ECUFlash\ModelFiles\Mitsubishi\VR4\

Need to make the "VR4" sub-folder yourself. And remember to unzip the base xml (think its zipped).

Edit: You will need to exit an re-load the application for it to recognise the files you just put in folder.

[Nutter_John]

why not just put them in the galant folder ?

all the xmls are out there but none of them are fully complete so it is a lot of trail and error , the 7202 are the most complete publicly

[TomTom]

I haven't tried any yet, I thought its probably better to make sure first... =)

Can anyone else confirm:

VR4Base.xml and the 2381003 files for 2000Legnum auto with 7202ECU ?

[Nutter_John]

whats the part number of the ecu , this is what determines the internal code

[TomTom]

It's MD362895 on the plastic case.

[Nutter_John]

do you have a 2.0 tactrix cable and ecuflash ?

if so you can download the rom image without having the xml defined , once you have downloaded it , upload it here or send me an email john@<this clubs name>.co.uk and i will get you the correct xml

[TomTom]

No I haven't, but the tuner I'll use has one. Only problem with him is he is a Nissan & Subaru pro and wasn't really keen to go through the lot and therefore asked me if I can get the xml file for it...

He got my ROM on his laptop, I'll ask him if he can send it to me and will get in touch with you, THANKS!

Have you tried the last two adddresses yourself? Using the following code in my xmls and changing both tables to 210 allowed me to raise my boost/load cut to 17/18 psi. I confirmed they were the correct tables because setting them to 110 gave me load cut at about 4 psi, and 150 was about 11 psi (as far as I can remember - might be a bit out on those figures). I can't comment on which is for manual/auto as I changed both tables identically.

<table name="#114a6 - Boost/Load limit" category="Turbo" address="114a6" type="2D" scaling="LoadBoost">
<table name="RPM" address="2CD06" type="Y Axis" elements="12" scaling="RPM"/>
</table>

<table name="#114b6 - Boost/Load limit" category="Turbo" address="114b6" type="2D" scaling="LoadBoost">
<table name="RPM" address="2CD06" type="Y Axis" elements="12" scaling="RPM"/>
</table>

Carl. I believe we will have the same ecu (98 pfl galant)

Be really good to have someone down here that knows how to do some basic tuning.

I wonder if its worth speaking to kenneth. he may even have a map we could use (ie raised boost cut)

Probably not going to do too much untill I get a wideband..

Yeah I've been holding off dicking around too much myself until it arrives.

Phosty - I did a quick drive lowering both of those to 120ish and still boosted up to 12psi, so don't think it worked. However I had it set to map RPM from different address, so maybe that is what screwed mine up. Table data now looks a little more valid. Afraid I can't confirm for another week until we have our CHCH meet and I get a new diff My previous logging for about 10 mins of thrashing it kept octane rating at 100 with no counts of knock, so be interested to see what it does when I have wideband & time. And fuel. Lots of fuel.

Fingers crossed wideband'll've arrived by then, but I doubt it! sigh. I had to go and get a toy instead, trying out the SLC-DIY wideband kit. Mainly because I had aspirations of putting EGT probes in at some stage as well.

Looking at hacking together a small module at the moment to convert SLC's serial input into a virtual comport and fake the LM-1 protocol so Evoscan will not know the difference.

Sorry, got side-tracked there. Well, when car's back on the road I'll drop an update, hopefully sort out something for me and Taylor to play with
