Wideband Lamba Sensor

Hi all, i am looking at a wideband lamba sensor and a AFR on eBay, are these an important feature on a high performance car?

Have you got a mappable ecu? Cause i would have thought the air fuel mixture could be adjusted on there

yeh i have a greddy emanage ultimate, however my locl mapper said that this is a rubbish ecu and i shouldnt be using it to run 450-500bhp

Well i wouldn't say its completely rubbish but i think its still a piggy back ecu, why not get a new ecu and just sell that one. Link or motec are good or even gems

The e-manage ultimate is far from a crap system. It's more than capable of handling a 450+bhp 3s-gte, has your local mapper ever used the system before? Considering I know of a couple of 205's putting out 350bhp on standard management the emu won't be working to anywhere near it's limit.

I'd buy yourself a a wideband and afr gauge as it's always a handy thing to have especially alongside an egt gauge and sensor.

If your mapper refuses to map it bring it down to the 'shire and I'll map it for you

A wideband is defo worth it cause you can achieve much more accurate air/fuel ratios as you can run the car in closed loop more often. Narrow band sensors are only really suitable for fixed map systems that generally run in open loop unless on partial throttle. Wideband can give you much better fuel economy gains too.

thank god you said that gtforbes you have already agreed to map my car anyway. hehehe so this wideband sensor with afr for about 200gbp should do the business? what is this other sensor you are talking about?

[GTForbes]

An egt (exhaust gas temperature) gauge, it allows you to monitor your exhaust temperatures, some tuners tune purely on this but the more the merrier lol. It's not a must have and it's a pain in the ***** to fit but worth it if you can afford it after the wideband.
