Whatever they’re called and whatever method is used, they all do the same thing – dump more fuel into the engine to generate more power. Some companies can re-program the factory engine management without needing to add any extra electronic hardware. Some companies may call it a chip or a module or piggyback ECU or tuning box or something else, claiming theirs is superior. And I'd have to actually say much better than having the chip installed.ĭP Chip and Howell Auto have been very helpful though the whole way I have to add.Why You Shouldn’t Support Mandatory Vaccinationsĭiesel Performance chips are electronic devices that intercept and modify engine management signals to increase the power output of an engine. And my power and fuel economy is back to where it was. So, its been disconnected for a few weeks now. There was some power increase but not that exciting, not as much smoke, but fuel economy was still woeful. So we turned it down to 4 and I may as well not had a chip installed as there was no discernible power increase, but still fuel economy was no better. Then accelerating more smoke would plume. It was quite embarrassing to be driving along at 100km/hr to be doing nothing but driving, and then all of a sudden a huge cloud of diesel smoke would billow out. At power setting 8 it also blew a stack of smoke. Towing my camper trailer (850kg) it was woeful. Whilst power certainly improved, my fuel economy unloaded went down by 50-70kms a tank. Well, as of tonight I just removed the DP Chip harness and sending it all back for a refund. Your clock radio is probably harder to sort out. What makes these two chips even better is that the distributors/manufacturers of the chip (ChipIt - as Robert said - is home grown) come into this forum and are happy to natter with us.Īs for how complex the operation would be - I don't think it'd be a big deal. In fact, the only chips I know of that do something AS WELL AS raising the fuel pressure are the Unichip and the ChipIt. The Steinbauer is pretty much the same as the DP chip. Most chips just turn on the tap harder than you can press the loud pedal. I know I'm explaining it in simple terms but it really is that simple! It's a bit like your garden hose - the aperture is a certain size, when you turn on the tap a little, only a little water comes out and when you turn it on a lot, a lot comes out. That's done by varying the fuel rail pressure. there are other factors, like varying the injector opening time, duration, frequency). The way to vary the power and revs is to vary the amount of fuel that goes in (basically. They don't have butterflies on the air intake, so every time the piston goes down, it draws in a full load of air. Diesels are actually very simple beasts (in theory).
