Hardly a D-Jet "Lover" - it's extremely ineffecient when cold. But so are carbs! The D-Jet EFI system is as simple as EFI can get. All the feedback the system needs with no overkill regulators and all the modern electronic garbage. I've thought about Megasquirt, just to see if I can tune it for more power. but I KNOW the D-Jet system can NOT be beat by a carb
Any problems with a D-Jet system can be resolved by a little troubleshooting. It might help to have the actual documentation (which I do) to get the car running sweet
