kyle_h95 Posted February 5, 2015 Share Posted February 5, 2015 Hi guys,Basically I'm new to starlets and any performance turbo car, so I've been going through build threads and what not and a few different things have caught my eye, for example, a wide band? I'm after a basic understanding, of what it does and how it does it & when it's needed!same for a fuel cut defender, fuel pressure regulator and probably a few more when I remember! Lol Thanks in advance! Quote Link to post Share on other sites
Gainzy Posted February 5, 2015 Share Posted February 5, 2015 Wideband is your air to fuel regulator gives you a accurate reading of those, the sensor gets welded into you exhaust not decat.. measures your readings from there,FCD is basically stops the car from hitting fuel cut when you up the boost, wouldn't bother with one just buy a plug n play ecu or a mappable ecuFPR it regulates fuel at a constant set pressure we already have one on as stock but people upgrade them for a more accurate fuel pressureThe only one worth buying is the wideband imo but everything all depends on what mods you want in the future.

TurboTobz Posted February 5, 2015 Share Posted February 5, 2015 Wideband - works as a lambda on a modern car but gives you a visible reading of air fuel ratio to ensure you're fuelling is perfect throughout the rev/boost range.Fcd - changes the voltage signal sent from map to ecu with resistance fooling it into thinking you're running pre fuel cut boost pressure. Preventing fuel cut.Fpr - rising rate fuel reg hanges fuel pressure with revs as they raise to compensate for air fuel ratio. Quote Link to post Share on other sites
Gainzy Posted February 5, 2015 Share Posted February 5, 2015 I don't run any of these if you have a good mapper and a decent ecu set up it's not really needed as the ecu controls everything you need, I would buy wideband out of those Quote Link to post Share on other sites
kyle_h95 Posted February 5, 2015 Author Share Posted February 5, 2015 I have a decat with lambda sensor, would I still need the wide band? I'm not going to bother turning my boost up till I have a td04, so will I still need a fuel cut defender? Quote Link to post Share on other sites
Gainzy Posted February 5, 2015 Share Posted February 5, 2015 You won't need the fuel cut defender the wideband had to be welded into you exhaust you need you lambda sensor still Quote Link to post Share on other sites
