Tinkernam 007 or Mr. Bond and fellow vanagon types

I have some background on this The European 112 Hp engine it had a10 to 1 compression ratio this by it self would I have come to understand accounted for approximately a 4 % increase in power IF you had 98 octane fuel to go with the 10 to 1 compression ratio. The European digijet 112 HP engine Also was not set up for a O2 sensor due to the fact that the Gas intended for this application was leaded fuel O2 sensors and leaded fuels dont mix well. No O2 sensor is the major difference in the wiring diagram best as I know and I run the European ECU in my US model digijet van and pass emissions no problem. I Have bought and still have for sale some of these European didgijet ECUs. Current Pricing $200 I have also spent mega bucks on chassis dyno testing ( back when ) using my big valve engine in my 84 Campa and a stock 84 van blue bell with a ported but other wise stock engine as my base line. The base line van Blue bell with 30 K on the mostly stock engine made 75 Hp at the rear wheels all day every time we did a dyno run. I did not test the European ECU on it much to my disappointment as I look back. The Boston Bob big valve Campa with a new fresh engine had mixed readings with no numbers I am willing to publish. My conclusions evolved over time as I considered the findings and differences of old Blue bell and the big valve Campa engine. One of the differences worth pointing out was the Campa big valve engine made wild HP numbers in the first run or two while it warmed up. But as it idled and changes or checking of tie downs and timing where made the engine lost power in a large way on the next dyno runs. I suggest that several factors where at work after much consideration and review of the differences in the engines. The Big valve engine was new and tight the rings had not seated to it made a little more heat sitting at idle. The radiator some distance from the dang engine and can account for swings in the engine coolant, engine compartment and air intake temps remember the van was not moving. This would be for me one consideration for the drop in power of the newer engine. The other component only came to my attention as I have just swapped the engine in the 84 Campa to a stock rebuilt longblock with all the new fixings so as to put it up for sale. That difference was that I never used the insulators for the fuel lines in the Campa big valve engine. Think what you want but I have had many years of dyno testing and have seen what a difference in fuel and engine compartment temp can do to power. The two final points I would make is that the European ECU had a consistent jump of 13 HP ( again at the rear wheels ) in the 84 Campa engine regardless of the any other factors as I swapped them back and forth during the dyno runs. And in every piston I have seen from a Dj 10 to 1 piston it had signs of detonation from the lack of octane. Signs of detonation as I define them are flecks of piston missing from the tops of the piston like to was on the receiving end of a shot gun blast. Just email me if you feel the need to see what that looks like and I have a pic or two that I can send you

hope this helps
