zeiss150 Posted October 20, 2005 Share Posted October 20, 2005 Hi Z people... Will any nissan O2 sensor (ie from a maxima, or 240sx, or whatever) work with megasquirt? Also will Megasquirt work with the a throttle posission "SWITCH" or does it need the potentiometer (spelling?) style TPS. Thanks, Matt- Quote Link to comment Share on other sites More sharing options...
Tony D Posted October 20, 2005 Share Posted October 20, 2005 Pretty much, but I used a three wire heated sensor from an 87 Z31. I prefer the heated three wire unit over the single wires units because they reliably give a switching narrow band signal at all operating areas, so you can run a wider Closed Loop Narrow-Band parameter---keeps the engine operating near stoch longer, giving better fuel economy in town that provided by the standard single wire unit, which usually cools off pretty quick once below 2000 rpms. That is if you run a Narrow Band. If you run Wide Band, you get even better economy because you can set off-stoch parameters... And you need a Pot style TPS. Not a switch. I used one off a 91 Sentra with an SR20. I liked the TB better than the one everyone else seems to use with the longer shaft. This SR unit bolted on and with one spring and quadrant change accepted the stock 280Z bellcrank bolt-on.... But it's not a "balck box" that looks like the old TPS, either, it's something with a flat-key drive and a grey connector. Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted October 21, 2005 Share Posted October 21, 2005 isn't that the same TB as the 240sx? I thought they shared the same TB. -Ed Quote Link to comment Share on other sites More sharing options...
