Is there much benefit to getting a tune done on the 380 with just the berklee muffler and the intake done? What kind of increases could I expect?
Also would anyone know of a place to go to have it done around the Taree/Newcastle region

You cannot tune the 380 in stock form.
Only option is full aftermarket kit....at the moment ;)

You would need a piggyback ecu to retune the 380 & would probably be looking at around 6 to 8kw extra at the wheels. Bang for your buck it's not really worth it although you will notice bit better drivability as well if tuned properly.
What I would be doing if you're searching for a bit more would be to install the RPW extractors, these should net you about 15KW at the wheels. If you still want more then get the piggyback.

Blackstar, does the wink mean you know about something on the horizon that the rest of us don't... Or am I getting my hopes up over nothing?

I've heard a rumour that someone has finally cracked the 380 ECU. But that's all, just an unconfirmed rumour.

would the Unichip from a 3rd Gen be the same as for the 380 ?

No not unless it was installed in the last few years & is a Unichip Q not an A.
The 380 crank trigger is not compatible with the older Unichips, it must be the Q.

I've sent an ECU to a guy who reckoned it would be done two weeks ago...he seemed to know what he was doing, ( a mate of SK).
But haven't been able to get him on the phone for over a week.
Only a matter of time really.
It can be done by simply unsoldering the 4mbit flash ram chip as per the photo i posted in the encyclopaedia section a while back.
The data will be in clear text and the mapping tables will be perfectly obvious...i have modded plenty of ROMS in my time...but...
The checksum is the issue...it is stored in the ROM itself and most controllers do a checksum of their ROM at startup...if it doesnt match it don't do very much except beep.
Now if anyone knows the checksum algorithm for the Bosch ECU...step right up....:)
(It's usually an algebraic sum of all the latitudinal and longtitudinal binary "ones", then byte and word swapped it if it a 16 bit+ cpu.)
Got it now? It's not an easy task....:)

I guess your talking about either David Hinde (Merlin) or David Shirley (Tephra) Both of those guess are heavily involved with the ECUflash software, especially Tephra who is widely known as the "ALTmaps/Tephramods" man

Ok well it's sounding like I will be going for the RPW extractors/high flow cat before I get a new chip then.
Is the lower intake resonator mod something I can do simply enough with a ramp? Do I have to completely unbolt it before I cut it or is it simple enough just to cut it while it is still on the car?

Plenty of threads here about the lower resonator mod.
You need to unbolt it to cut it properly.
A ramp or jack & axle stand will make it easier to get at to unbolt.

For all we know they could be using the standard UNIX "checksum" algorithm...after all why re-invent your own, or was MMAL that paranoid?

Not Mitsu, Bosch.
Who knows what algorithm they used, 'sfar as I know people have been trying to find out for six years now but no-one in the know at Bosch has spilled the beans.

Got onto him today.....I originally asked for the flash ram chip to be refitted with a socket...trying to get the socket was taking all the time....was taking all the time up trying to source one.
Stuff it i said plenty of ECUs on my shelf...just resolder the focker.
Now we wait till next week....man definitely knows his stuff, has done quite a few different ecu's.
Won't say who cause there are forum tossers everywhere who annoy people.
I'll be enthusiastic of this little project for a while ...(2-3 months)...
If no reasonable progress I've decided on installing the Link Extreme G4 full ecu replacement..

It is most likely that the checksum is a very simple cumulative addition of all of the ROM bytes except for the checksum value itself. Using checksums at all is primarily a defence against a corrupted reflash (which is not unknown in automotive usage), rather than an explicit lockout mechanism (despite what people may think of the Bosch/380 situation). BTW, I got the impression from a couple of references I found that the code used in Mitsubishi M32R based ECUs (CJ Lancer Ralliart, Evo X etc) actually has several checksums stored in the ROM.
If you can get the ROM image out of an ECU, and find a dissassembler package (such as IDA Pro) that supports the MCU core, then you should be able to extract the information with some effort and lots of time. The checksum code would be likely to be executed very early in the initialisation process, so should be amongst the earliest code fragments to be disassembled.

It's an ST processor...same as a foxtel satellite set top.
Got all the tools mate, but 4 megabits takes quite a while....best to do just a targetted edit of obvious parameters like mapping tables and rev limiters.

Thats interesting. ST chips are used everywhere from automotive, wireless, digital and industrial. Quite common, with a large manufacturing footprint.
Not Mitsu, Bosch.
Who knows what algorithm they used, 'sfar as I know people have been trying to find out for six years now but no-one in the know at Bosch has spilled the beans.
If Bosch developed the program, but for data manipulation, would they own the IP or MMAL? I would assume for R&D reasons someone at MMAL would have some knowledge. I guess one day we'll find out.

yes they are....and the last thing the Bosch programmers did was to blow the software fuse that allows the code whithin to be accessed...it's a full reflash or nothing at the moment.

I am certainly awaiting the outcome on this as flashing the ecu would certainly be a lot more economical than a piggy back

Is this in regards to adapting a set of magna headers so they fit a 380? I think the only thing that needs to be modified would be the o2 sensors bungs and the Y piece. Other than that, they should fit ok. The Magna headers will produce more low down torque than the RPW headers as they have shorter primaries.
Will be interesting to see how this works out, cause I have been thinking of doing this for a while.

Can come down this week and if not chris will be there anyway, and hes just put a set on.
Basically what we need to discuss is what else you'll be doing at the time (mostly do you want a cat where the fake one is currently) because part of the deal is they come incomplete, chris and i are willing to get them finished up and if you like installed as well. (incomeplete as in they have no oxygen sensor bungs - this is a good thing because rpw put them in a dumbass loacation!) and your decision on the cat front will affect what we do with the sensors.

No sorry Braedz this is getting the RPW extractors without talking to RPW. if you are handy with tools etc will come out cheaper, if not will be around the same price as if you got them from RPW.

Hey Stormie,
I'm just about to purchase at long last an Innovate Wideband 02 sensor/gauge kit so I can finally fit my Interceptor kit. I'm tossing up between the basic analog DB gauge + LC-1 kit or the new digital (but not expandable) MTX-L. I was curious to know if you have had any feedback on 02 sensor position in the pipe?
I plan to leave the standard narrow bands in place and weld a plug into the side or rear of the clamshell of The FRONT BANK ONLY to sample the AFR's for tuning (before the front bank primary cat).
I'm a little worried that this means I'm missing the whole rear bank of cylinders (3) from the sample, but I can still read the narrow bands to make sure nothing significant goes wrong there I suppose.
The only other alternative is to mount the bung further down the pipe after the primary cats which I really don't want to do. I'm getting a Berklee fitted in a week and will get them to weld the bung in at the same time (anybody think messing with the third cat is worth looking into while it's on the hoist?)
Anybody have any opinion/intelligence on this?
Cheers,
RG

Seriously guys, can anyone who has fitted an 02 sensor to the 380 give me some advice on the best place to fit the bung, depth you used etc.?
There's not a lot of room at the top of the clamshell and I'm worried it won't fit there.
