Wideband AFR questions

[slow2]

just had a look innovative set up and it does provide both signal outputs using 1 lambda probe, so no problems there if you decide to buy it

I have an innovate AFR setup and it gives out a narrow band signal for the ecu so you can run ok with just the wideband and still give the ecu the info its looking for.

There's a massive thread on it on here somewhere. Basically it holds back on full throttle slightly. So far I'm up to over £5k trying various things.

Read the thread you referred to, I really feel your grief.

I see from one of your other threads that you were going to sell it last year ?

Keep the faith with this fault, and post up the cause when it is found.

Good luck.

Sure. Make sure to unplug all the connectors from the standard lambda though, don't leave it hooked up in free air.

Hi Dimitri, good to see you back on here, you seemed to be quiet for a while. I for one missed your incisive inputs.

Haha. Yes it has been an on going fault. I'm a mechanic by trade. If it were a customers car I'm sure I'd of sorted it by now. Problem is, I'm so busy I never get enough time on it. I have an RS2 set up waiting for it on e this is sorted.

And no, I've found dry storage now so it's staying. I'll never sell this car!!

Ah right. Excellent. I missed that all together. It's ordered now anyway as it's a useful tool for me to have if nothing else.

My car hybernates due to lack of time mounting my afr and boost gauge and measuring fuel pressure.Runs resonable but sometimes i feel something keeping it back.Should be simple:fuel,boost/vac or knock sensors.And Dmitri will tell in a seccond looking at load if maf is ok.But when??

Yep! That sounds just like me! When I do get an hour or so to spend on the car (not nearly enough anyway!) there are a million other things I aught to be doing!

Fitted it up, as stated in my latest post, it has a 290bhp ecu fitted at the moment, and on boost it's running 10.8 or there abouts. Since my issue is only slight I still feel I'm missing a small boost leak somewhere but with all of the parts that are new/upgraded I'd struggle to see how!
Shame I have no boost check kit

Have you tried linking Vagcom up and checking all sensors read correctly? I think altitude sensor knocks power back a bit for example.

Also, is there a way to see if the ECU is knocking timing back a few degrees through vagcom? will it show a code or do you just have to watch the BTDC channel?

[HMS-S6]

Hi Martin, all of the sensors read lovely unfortunately. The only real reading I can't really comment on is the annount of retardation on the timing as although I have the readings from my car, I have no benchmark. Does anyone know what is considered OVERLY retarded at around 3-4000RPM at WOT?

[HMS-S6]

I would add though that I have done various things to fool the sensors (i.e, bolting them both up to the front or rear and neither has had any effect)
