Magneti Marelli IAW15P ECM pictures or schematic

Long shot I know, but I'm trying to figure out my options. I have a 2007 450FSR. Was out for a ride yesterday and it started to have a slight hesitation on initial throttle application. Running totally normal other than that. Symptom lasted about 15mins then the bike died. Tried to restart, no electrical power. Checked battery connections and found battery badly swollen. Pulled battery immediately and set to the side. Called for a ride. Got bike home and tried to start with known good battery, thinking maybe the voltage regulator went out and took the battery out. Still no signal. Jumped main relay and was able to get power to the cluster and prime the fuel pump, crank engine. No spark. Followed the smell to the ECM. Opened it up and found 2 burnt resistors-tried to clean to get the values off of them but now they are totally illegible- and a burnt chip. No other visible damage. This ecu is incredibly hard to find a replacement it seems.
TLDR: Does anyone happen to have a schematic or a picture of this ECM that I can get the values for these resistors? I'm going to try and repair the board.
Alternatively, does anyone have any experience or wisdom they could share on running a mega squirt or other aftermarket ECM. I'm not well versed in tuning from scratch. TIA

Pretty sure that's the same ECM that's in my 2004 450FSE... I'm in the middle of doing other work anyway so the ECM is easily accessible. Is it easy enough to remove the covers and whatnot to access the resistors that you need photos of without risking damage to my own ECM?

An other option to Megasquirt could be the Ignijet from Ignitech. I have no personal experience with either, but have used Ignitech ignition on my Bimota. I found the Ignitech people easy to work with.
There are also some DIY ECU projects around if that is your cup of tea.

Not easy no. The ECM would have to be unsealed. Was just hoping someone had some pics. I took the board to a local electronics repair guy and it is pretty much toast anyway. I found an ECM from a 2005 and just finished the install. It seems to be the same, a couple different numbers on it....might be a different tune. I'm up against what seems like a lean bog, but the bike was doing this on the last ride. Up until now, I just assumed it was to do with the voltage reg/rec killing the ECM and the battery, as that happened about 30mins after the bog/hesitation issue. Gonna look at the valve adjustment and fuel pressure before I do any more ECM diagnostics

I suggest measuring the resistance of the temp sensor on the cylinder head. My bike was also bogging down and hesitating(especially when engine was up to temp). In my case the temp sensor was reporting 9.1kOhm at ~20c which was totally incorrect. I had a spare and replacing it resolved the issue. It a quick and easy check you can do with a multimeter.
