Here is some interesting data logged from my little old 404. I thought some of us, may like to see what Engine Management data logging is and what it can tell us.
This is a capture of a run yesterday. 2.2l ZDJ Douvrin. Standard apart from rings, new profile cam and valve springs. It runs a Link G3 ECU. Oh it has a t3/t4 Turbo with intercooler and my own design exhaust system.
The MAP figure of 225 equates to 18 psi boost. WB Oxy is the mixture table where you can see 12.63:1 (12. to 13.5 is about dead on for max power) RPM is 4270. This is in 3rd gear at 60 mph. We gave it some more welly and achieved 18psi through to 6700 rpm with about 12.7:1 all the way through. Also note we can log air and coolant temp, timing injector duty cycle, many more things.
Adjustments are made to the fuel graph percentages, relative to manifold pressure and engine revs.
For interest's sake 6700 in 3rd is 94 mph (150kph). One more gear to go, too. At 150 kph in top gear the engine is at 4720rpm with, you guessed it, 18psi at the touch of the right foot.
100kph is 3150 rpm in top.
Lakeside beckons in the future!
