I have read that there is others selling the chip for the 022D ECU BUT I can tell you that I tested the ozy chip and it lost 4 hp at the top end and was lean all threw the RPM range  The older 83 to 85 vans used the digijet injection as did all the European vans including the 10 to 1 compression ratio 115 HP engines BUT they had a better (the best) ECU. I have tested the European ECUs and thats what makes the difference in the 115 HP engines The increase in compression could account for only 4 % increase in power if you could buy the correct fuel to match the compresion ratio.
I have some euro ECUs in stock and in my testing with my big valve engine it added 13 Hp just by swapping the ECU to the European unit.
     Keep in mind that the 10 to 1 engine was intended to run on leaded fuel so this ECU will not have a closed loop to correct the mixture. This euro ECU also has a rev limit of 5600 RPM
I only offer these ECUs only with my big valve engines due to limited quantities. Ken at vanagain might have a few of these left @ $250
I have one in my van and love it I pass emissions with no cat
