A little update on my car. Little details are important for a non standard project...
The engine works, but i was rarely satisfied by the throttle response in the past time. I had a lot of "hole" or something like misfiring.
Along all this time, i changed lot of times settings, VE maps, timing, Acceleration enrichment etc...
I change also the RPM circuitry : instead of the MS VR conditiong signals, i made a new one with the LM1815 chip, wich is designed for this purpose, and suggested on the MS forum.
( like the one suggested here )

But still, i had some little problems.
I just found this days that the INJECTOR DEAD TIME, wich is usually suggested to keep at 1,0ms , what not good for me. I investigated a bit on the web, and found that usually, specially for LOW impedance inj, the numer is more around 0.6 - 0.7 , and makes BIG differences in VE table and roundness of engine health.
I am now running at Dead Time 0,650ms . I had to completely retune my VE maps after this ( easy to do with Wideband and Tunerstudio pro ), and the maps did "smoothed" out a lot , so they are more good to see now!
And seems that this made the throttle response and linearity to went good, and no more missfiring.
I am now waiting a new alternator , new blow-off valves , spark plug and little other things for happynes.
Good for the new spring season
