I've not tried flashing it back in yet as I can't afford have the car out of use for any length of time and don't have a spare ECU - it was nerve racking enough just reading and replacing the chip. Luckily it all worked when I put it back. I'm still going through the code with EVC figuring out the maps. If I can get a spare ECU for sensible money i.e. <200GBP I will be soldering in a ZIF socket so I can swap out the flash more easily, then it will be full steam ahead! I don't mind sharing information on the forum but I'm afraid I an reluctant to disclose too much more as I don't fancy giving away over a year's worth of hard slog and investment in kit on the Internet for nothing, at least not yet. PM me if you want the details.
Cyril: What was your original question, I can't see it in this thread? The site you link to doesn't seem to work for me, also the pic you show doesn't look like an SLK ECU but perhaps that is just a generic pic.
Here is my Crossfire ECU before I took the chip out.
No need to divulge the secrets to the world yet... We'll chat via e-mail...
In answer to your question, yes we have accessed the ECU via the OBD port and "observed" the data. A fellow racer invited me over to his shop a few weeks ago and I used his
http://www.drewtech.com/products/cardaq2534.html This system is compliant with the Daimler Chrysler Pass Thru and allows reflash via the KWP2000 (ISO9141/14230) protocol. It supports both onboard and offboard reprogramming... The only drawback is that you have to subscribe to the DC StarTech system and access the OEM software via their online system which, since we didn't have the OEM programs backed-up anywhere, we were reluctant to start changing values... Once I have a full version of the OEM, I'll start fudging with the code... To be honest, after looking into the architecture of the program and my lack of experience with this type of programming, I have decided to achieve my performance tuning via piggyback systems for fuelling and timing and dual wideband 02 sensors for constant AFR's. This can be achieved at a cost of about $1,200 and will give me better and fully adjustable maps that I can load onto compact flash cards...
Not to knock the PowerChip and Upsolute one-size-fits-all reflashes, but I like the flexibility and adjustability of a piggyback system and the price is not much more than a one-time reflash from RennTech...
I'm close (fingers crossed) to getting a full copy of the MB SLK320 software from Bosch, I'll keep you posted...
