Need to borrow a MSP and MP3 ECU...

[reuben_j]

Guys,

One of you has to have one of these lying around I can borrow. I'll pay for all the shipping. I have a 97 626 with the 98 distributorless 2.0L, EEC-V ECU. Hardware within the ECU should be identical to the MP3's EEC-V and MSP's EEC-V ECU's. Any binaries I can get will help me with the firmware reverse engineering. My engine is NA for now, so I want to install the MP3 firmware on it for now. Later, I will be installing the MSP turbo setup, and will need the MSP firmware as a starting point. I have included some pictures of the actual equipment I purchased, from www.moates.net, for the retrieval of the firmware from the ECU. As you can see in the BURN1_attach.JPG, our ECU's have a J3 programming port in the back. This is a debugging interface which allows for real time tuning. The last two pictures, show the F3 device that stores the alternate binary. When this is plugged into the J3 port, the ECU will use the flash onboard the F3 device. The BURN1 device can read the stock flash binary from the J3 port, and can also program the F3 device with an adapter shown in the F3_program picture.

Thanks!

most of the mazda ECUs ive seen are glued there... to ruin any attempt at connection

They all will have some type conformal coating which has to be cleaned off the J3 port pads. I have seen two types. One was a white paste, which wiped off easily with some rubbing alcohol. The other type was a thick, clear silicone type coating which can be scraped off with a razor.

I guess you're trying to figure out what values does what now huh.

Yea, I'm working on it when I have time. There is a binary reverse assembler (written a few years ago) I have been adding enhancements too. Having multiple binaries (for the same engine), tuned for different applications, will make the job much easier.

I could probably do the MP3 ecu..for how long would you need it? My car will be down until probably around the 17th..Could I have it by then?

this sounds promising.

Subbed!

Props for trying this!

good, then maybe you could make some money fixxing the overly rich condition that the msp's are known for.

Reuben, I am very interested in what you have found out, please share!
