Some progress on this front. I finally swapped this Speeduino PnP ecu to my daily that I have been meaning to do for long time. I found some nice flexible hose to go between the MAP sensor and bulkhead connector in the case:
LSU 4.9 sensor and some cable to connect that to the ecu:
Running nicely on the car:
The car runs and starts great. The poll level cam trigger was introduced in 202103 FW version and now even with sequential injection, the engine starts immediately after touching the the key. Also seems that the cold start features in Speeduino are in good shape, because it was -20c one morning and it fired up right away even with e85. I have now been using DISA valve with programmable outputs and the electric thermostat also seems to work through programmable outputs(video):
I have now set the E-thermostat to be on if the MAP is over 80kPa and coolant temp over 90c, so it works pretty much like with stock ecu, cooling the engine when there is more load. So most of the nice features that these engines have, also work with Speeduino.
The intake vanos works pretty ok in on/off mode, but I have been now working with dual closed loop VVT to make the intake and exhaust vanos working in closed loop PWM mode. What a huge job that has been, but I'm now really close to the point that I can actually drive the car using the closed loop mode and start actually tuning it.
I also had some problems with the CAN instrument cluster, which worked at bench, but in car I had random issues with it. Probably the addition of ASC/ABS CAN messages did cause some problems. There is now updated code for the bluepill to solve those issues on my GitHub and also I have added there some info regarding frequently asked questions:

It also looks like that there is some great data flowing through the CAN bus like individual wheel speeds and so on, so once the closed loop VVT works, I will try to establish bi-directional serial3 connection to speeduino, so that I can have that data on Speeduino too.
