wideband AFR advice.
Turbo Mini Forums

ive been a good boy and done plenty of searching on the forum to see if i can get some info on wideband AFR set ups.
found alot of info regarding the best ones to get etc but my question is this..

i can pick up an AFR gauge for £40 and a semi decent universal O2 sensor for about £20...a wideband set up im looking at atleast £130 dependant on spec etc.

just wanted to know what benefits the full wideband system would have over knocking up my own cheap system.. are the uni 02 sensors not alot of good(accurate etc )..

baring in mind im running not too far off standard spec etc, and altho future plans will see me pushing for more power and upgrades money is abit tight at the minute, but i want a way to monitor my AFR to help me get a better set up engine.

thanks in advance

google for the difference between narrow band (what you describe, universal sensor+gauge) and a true wideband.

narrowbands won't give the resolution or speed of response that a wideband will give.

cheers boys...kinda what i thought really..for the sake of another £50 itll actually do the job properly and give me solid accurate readings..look like the bank balance is getting a battering then :)
oh and cheers evoloution, ill be sure to check out some info on the difference between each set up

think of it as an investment, i have put a ciggy socket adapter on my wideband, so can just bolt into any car to see what the afr's are like, its one handy mofo!

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

good point well made..ill think of it more as a long term mod that can stay with the car regardless of what spec it gets to...itll always be very handy.

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

im looking at gettign this

i like the idea of having both a numerical reading and a light indication aswell... it looks like a decent system even if not the most attractive looking gauge ever

Never used that gauge before but it looks cheap and crap to me. Spend an extra few quid on one of these.

If something is worth doing, it's worth doing half of.

thats a MUCH nicer looking system and worth the extra £20...i guess sometimes there no subsitiute for abit of extra money for some quality..thanks john

AEM UEGO Wideband is what I'm using, as are plenty others including John and Andy on the van. However, the Innovate kit also seens to be popular.

Well worth it. Plus it'll give you an output to a Data Logger, Megasquirt or Megajolt etc.

You will not regret buying a Wideband.

Minivanless, but reluctantly happy living with the decision. There'll be another one day.

well boys ive taken the plunge and am now waiting "1 workign day delivery" on my new AEM UEGO Lambda Wideband AFR Gauge w/ Bosch Sensor..happy days..and if my girlfriend asks ill tell her it was £40 haha
ill get that fitted asap and in the mean time check my fuel pressure is rising with boost and my actuator..i pick up a foot pump off my friend on saturday morning and ordered a t peice to fit the fuel pressure gauge temporarily :)

You wont regret it :)
Alot easier to fit than the innovate jobbies aswell.

Here's my early dash install phots taking shape with the AEM Wideband and the black bezel it came with from Funky Products.

I didn't like the look of that so decided to modify it, and the boost gauge, to Smiths bezels to match my other instruments. Unpicking the bezel without mullering a £200 gauge was an experience not to be repeated ! But worth it IMO. And a great piece of kit.

If you need a hand fitting, give me a call. It really is a piece o piss, just follow the instructions to wire it up and make sure you weld your bung (ooh ahh) into the downpipe at the right angle to drain off and prevent condensate build up affecting the sensor (I think the sensor angle needs to be 10 degrees off the horizontal pointing downwards). I fitted mine just before the bend in the downpipe, about 10 inches from the clamp.

Does your car idle at 16.9 AFR then, Richard ?

Boost gage reads zero therfore the engine is nt running

Smarty pants!

If something is worth doing, it's worth doing half of.

There is a difference between trying to be smart ^^^ as above and actualy being smart

I try all the time and usually fail miserably.

BTW bman. Glad you bought the AEM. You won't be disappointed.

I've bought cheap gauges in the past expecting them to be ok, only for when the arrive to be bloody horrid!

I especially wouldn't scrimp on somthing like wideband as if its wrong it could cost you an engine.

No doubts the van's motor would have been very poorly by now if we didn't have one.

If something is worth doing, it's worth doing half of.

thanks boys im feeling abit better about the expendature now :) all ive gotta do is work out what AFR its mean to be running and when and i can see whats what ...im presuming there must be a thread on here of all the AFR measuremtns at idle, acceleration etc etc so will get hunting

thanks richard, ill def be sure to drop you a call if i get stuck :) ill try and make it down this weekend to see the van aswell, although my list of things to do has got very large haha turbo timer to wire in as well now

Aim for 15:1 on idle and depending on boost, down to around 12:1 full chat
