air fuel ratio gauges?????

[mark_saxo]

anyone fitted one?

just wondering if they are good and go on easy

[RIBstaff]

search?

[mark_saxo]

eh????

[hesslevtr]

he means use the search button mate there might be some info about them there

i dont know anything about them or id answer your questions

[mark_saxo]

theres nothing

[Scott]

yes air/fuel ratio gauges are very good and very handy at showing exactly what the engine is doing.

Fit jut like an other gauge but i would buy one that comes with its own lambda sensor rather than tap into the original

[mark_saxo]

cheers, the sensors are 100 quid each

[cammedvtr]

like any other gauge, there only as good as the manufactur wants to make them, id try to buy one with a certificate or accuracy if you want it to read correct...

[Ratty]

if you want a proper accurate one then you need a £1000+ wideband one, not a £100-£300 narrow band. if its not a 6 wire wideband sensor it wont be as accurante, however narrowband is fine as an indication which is to .1

[cammedvtr]

im just saying i have a oil temp gauge that is worth £80ish quid and thats about 3degrees out... and this has no certificate.... its up to you mate

[Ratty]

as long as its matched to the sensor and its from a good company then you cant go wrong, ie luminition with matched sensors, alpha, motec etc

[gafvts]

i have not fitted one but i have had one fitted by gmc and think its very good

[Ratty]

it will be the alpha one, its matched to the sensor so its fine, also lights up all the lights so you know exactly where the fueling is, same one ive got.

[citroenaxgtr]

sorry to but in but what are the ratios supposed to be on a standard grey top vtr engine??

[Ratty]

what ratios?

[citroenaxgtr]

the air to fuel ratios mate!.

[Ratty]

well thats what the lambda and ecu modifies all the time, thats what your lambda sensors for, there is no set ratios, ecu chooses the best based on air temp, engine temp, water temp, oxygen content etc
