Understood. But I imagine that since everyone's diffs perform more or less the same (whereas engines all have slight performance variances and everyone has slightly different engines mods), eventually the folks doing the development in this thread will develop a bunch of set base maps for the ACD ECU depending on how you want the car to behave.

Regardless, it seems like the development (especially w.r.t. the actual maps) is some ways off, so I'll probably go ahead and get a Gruppe-S ACD ECU reflash (at least to tide me over).

P.S. I'm sure you already know this, but Gruppe-S basically offers 3 different maps, so it's not like they individually tweak it for your car or driving style, you just choose which one of their 3 off the shelf programs you want.

When the development being done in this thread is finished, ideally there'd be a set of base maps you could load that would get you in the right ballpark, and then allow individual (non-real-time) tweaking of parameters to suit setup or preference.

 

finally got my OP2.0 cable ...
will try this WE to read my oem & my ralliart ACD+AYC ecu's

is there any updated xml definition available vs the latest posted by Ceddy ?

 

 

Hondacan ???

 

any updates guys for that great work ?

 

no success (OP2 + latest ecuflash 2.7.0070 - IX ACD/AYC ecu in car)
log windows says 'sending init 2' and then it stops

has anybody already succeed to read a IX acd/ayc ecu 'in car' ? or do I need to remove it and read it on the bench as described in previous post ?

 

Remove the ecu and bench it

 

whats the latest XML file for AYC?
whats the latest XML file for ACD?

can someone send me a copy, thanks?

anybody got the ralliart AYC/ACD roms yet? can you send me a copy, thanks.

any progress on AYC/ACD xml maps?

I got the MH8303F reflashing to work with OpenPort 2.0 and ECUFlash, here's a how to guide I wrote up... http://www.evoscan.com/technical-veh...hi-lancer-4g69

I'm going to continue writing and adding technical guides to this page: http://www.evoscan.com/technical-vehicle-manuals

do you think the new mitsubootloader reflash method thats been added to ecuflash will help with EvoX AYC/ACD ecus? what do the new memmodels mean? is it just 512k and 768k memmodel difference? Acamus do you know?

RALLIART: mitsubootloader M32176F4
COLT: mitsubootloader M32176F6
CAN: mitsucan M32186F8
ACD: mitsukernel H8539FA

 

Hamish, note that the Evo6 AYC controller uses a Motorola chip.
and
can we have a driver/flash for the year 2000 WRX please.

 

^ Has anyone tried to download Evo6 ACD with 68HC16 reading template?

@Hamish, if you can get a picture of processor in X ACD we may get further.
I have not seen it yet.
The processors used in mitsu ecus (Colt...) differ from one seen in X models by size of a ROM. So there are 512, 768 and 1024 versions of the same processors, many
including me requested Colby to add a support.

 

you mean evo 6 AYC? iv got a unit here but am unsure of the wiring required.also which dropdown is needed?

The sclerosis must have started hitting on me

MH8405F is used in newer Mazda ECUs.
I believe 8401 is variant of the same processor with smaller ROM.

Maybe we can get some help from Mazda community on processor type?

 

I have been browsing the Renesas site for quite a while querying for 144 pin processors and the only model that I have found to have correct pin assignment was 32176 or 32192. So it seems its m32r type of processor.

Now over to Colby and S-AWC owners
