If it does, it will be only for the basic emissions data for EGR etc. the engine is still mechanical so won't have anywhere near the sort of data throughput an 'electronic' engine has, like a td5 or MS'd V8 etc.
Fridge, very cool, I'm liking the budgetry aspect too. Assuming the Palm sits there as a passive listener, what about running two off the ECU, twice the data to look at then, one for graphs, one for numbers ?
