I recognize the top pic - all the ECU\'s for the FC that I\'ve seen look like that one - I don\'t recognize the bottom ECU - what car is that off ?
 
Your chip will almost certainly replace the eprom on the board - part number will be something like 27128 / 27256 - maybe with a letter in between 27 and the latter part of the number.

so....

engine start very nicely, exhaust sound looks a little bit diferent, but most importatnt

all the year I had a bug wich after 10 minutes makes fuelcut or boost cut
any way only way to go forward fast is to turnt of and turn on ignition just 1s and you are ready to go again...

know then problem is gone. But after 17min I turned of the engine waited for 2 minutes and started again. I found that ECy think that engine is cold and again keeps for 5minutes 1200RPM

so propably my termo sensor is dead...
