Has anyone used something like Galletto to read / write to a ECU?

Specifically a 97 E320 and 97 SL320 ( M104 engine ) 97 was the first year for Bosch Motronic ME 2.0 / 2.1 computer , 96 and prior was HFM

I want to clone a ECU from the SL to the E as part of developing a new engine for the SL.

The next step would be to find some map sniffing software so I can alter the fuel / spark map.

97 uses CAN bus to communicate with other modules ( like the trans controller ) I've got a demo board from Microchip to sniff CAN if anything on that end of things turns out to be helpful.

Thanks

Tuning software is very expensive. Unless you are going to be a professional tuner it is just cost prohibitive. I am working on can bus stuff. It is just time consuming mostly. There are a few messages that are hard to figure out. If you are swapping the ecu this is not hard. There are several companies that erase the vin and then you just swap in an learn the new das.

EDIT updated map software.

Yea, I know, but I'm always up for some sort of silliness. Part of a project it looking at a wide range of possibilities then picking a smooth path.

What's ironic is that the Sl is my first EFI car since I was buying / fixing and selling D-jetronic type 3 VWs in the early 80's!

Beckmann Technologies is probably one of the vendors.

Being able to reflash a ECU with a purchased file would be better than having to ship the ECU out every time.

EDIT

I came across software that looked at the bin and highlighted areas as maps. This was not a direct tuner software as it required the user to do the leg work. $ 500 US. http://www.batronix.com/shop/software/chip-tuner/chip-tuning.html

Too expensive to me would be more than ~ $ 2,500. US . If I went with a aftermarket ECU, rewired , made a system to translate CAN to and from the ECU to keep the trans happy / aftermarket trans controller, the total would likely be more. I have a state emission test to contend with also so the OBD 2 system needs to be up and running. ( I've got a theory to keep that end of things working. )

I've read some of your build, interesting stuff.

I've got a couple of goals. A low pressure turbo / supercharger for the SL320 to fill the low end power hole. ( Something like a Turbo Techniques system where 100 HP gain is easy.)

With information gained, a much stronger motor will be built for the other SL. The 2nd SL will be gutted , caged and primarily be used for track days. ( But will retain street legal status. )

I've built race cars before so the mechanical portion of the build is no big deal. I've got a good electronics background just not much time tuning a ECU.

Well the tuning software I have seen is dimsport. It starts off way North of 2500. You should be able to get a remote tuning cable for this. Custom remote dyno tunes are pretty normal these days. Where are you located? Give Eurocharged a call. They have fair prices for the base tunes and do custom tuning by the hour. It can be done over the internet.

What transmission setup are you planning on using? The stock transmission in a 97 can only handle about another 100hp but you will have to increase the pressures to get it to hold. It can be built to handle more fairly easily though. I plan on having the PCS standalone tcu on the can bus in the next few months. I am doing the later model transmission control units 1st but have a bit of the info for the older stuff already. My plan is to have the egs51 and 52 plug and play in the factory environment for Mercedes, Chrysler, Porsche, and Jaguar.

I edited my post above.

Just a short post today.

The map finding sw is

Chip Tuner Module (Software)

At $ 500 US it seems like a good deal. But it mentions nothing about generating check sum values, I'm guessing this is a major hurdle unless the check sum is dictated by the processor and uses a well known algorithm.

My 97 SL320 has a 722.6 electronic shift 5 speed. There was a factory change mid July. Pre July 21 1996 was first gen 722.6 and July 22 1996 was the uprated trans and trans control module.

Near as I can tell, all factory rebuilds are the uprated trans. I don't know what had changed inside but it should be replicatable, using the later TCU should complete the package.

Supposedly there was a valve body change around 99 or 2000. There is a thread in the tech forum that talks about changing some pre 99 valve body springs.

Not including any updates, the 722.6 is the NAG1 ( New Automatic Gearbox version 1 ) used by Chrysler so cores and build info should be in abundance.

The trans computer sends information back to the ECU so spark timing can be retarded during shifts. I'll pull my Mercedes product feature / systems intro on the 722.6 and report what info is transmitted.

The later model transmissions were just updated with better parts, bearings instead of bushings etc. The valve body and tcu changes were just better shift quality. New or old it does not matter the transmission in stock form can only hold so much. As far building it to handle more power I would suggest just having it done. You need to add clutch packs and by the time you buy or modify the parts to do it it is not cost efficient or get a v8 transmission and tcu that will work with your car and change the final drive ratio to match. Still not cost efficient. The only cheap things you can do to increase the power handling is an upgraded valve body or just the blue to solenoids for pressures. This makes them shift very harsh though.
Torque management will not handle all of it for you.
I would advise going in and replacing the k3 clutch pack from one from a v8 and then adding as many clutches with the thinnest steels as possible on every other clutch pack if you want to do it yourself. Then set the clearances as tight as you can that they do not drag to much. Put the blue top solenoids in and it should hold together for a while.
