Why you running a 4bar FPR on a stage 1 map?
Ignore the IDC,s I always saw 100+% when logging on Revo stage 1 and 2.
Lean on the wideband: Any exhaust leaks? Boost leaks? N75 duty? Any fault codes?
On my stage 2 i ran the wideband setup in the second lambda position (decatted), then cable tied the OEM lambda to my anti roll bar still electrically connected. Worked a treat.
Some logs would help.
Hoping for a solution to this on going problem!!
Found some time recently to dig into the problem that is my ibiza at the moment, problem as above!
Now I have checked fuel pressure, seeing 3.5 bar on idle, 5.4 ish on boost. Running 4 bar regulator.
now experiencing it throwing up fuel system too lean code and lambda b1s1 malfunction in circuit.with block 032 showing 25% sometimes! But only so often, and lots of black reek out the back! Sometimes to the point of no longer being able to drive due to misfiring and plumes of black out the back. All the time seeing steady 14.7 give or take a few .1's on the wideband.
Been reading into the lambda code and can point to maf? So health check the maf. I'm getting about 175 g/s peak, 5.5k rpm ish, still seeing 30+ ms Injector times,
Or wiring.. Had a poke around and visual inspection of the localised lambda wiring, seems fine! No obvious breaks, pins on plugs clean.
Do I either..
Buy a new b1 s1 lambda probe, and hope it solves the issue.
Buy injectors, assuming they are not functioning correctly and causing the ecu to demand huge injector loads to run the car.
Or get another ecu, assuming the map is at fault, and demanding huge injector loads possibly caused by a cowboy mapper?
Helps always appreciated folks!
wiring/ECU fault the " lambda b1s1 malfunction in circuit"
Seen it several times on ibizas
not found a cure for it
If your wideband is staying on 14.5 its not working properly
when that faultcode appears it latches the lambda adaption to +25% which is the overfueling. You will see the sensor voltages, likely on both pre and post cat lambdas dropping to near zero volts whilst this fault condition is active
my aem's on overrun go off scale lean as on overrun >2krpm the injectors are switched off. Somethings up with yours, I'm convinced.
I've had reliability issues on my AEM gauges of late and stopped using them on the dyno. (PLx device now)
We rewired the ibiza we had in, direct from lambda to ecu, and swapped ecu's and still could not rid the car of the fault. something else in the shared circuits at play... "somewhere" - we never found it. Disconnected the lambda it was fine.
I would hope that a convert to wideband, as the wiring is different and our loom is what we make up here, would fix something like this, however, without knowing what the actual cause is, there is an element of and
Does the resistored part of the loom get replaced by your new part?

It's seems to be a common link on cars with this issue. shame it was done before I got it,
It's worth a try removing the resistors I guess... See if it disappears.. They may degrade in the heat above the rocker cover/ turbo area causing something to happen.
I'll get to it searching for an un touched loom!

Bill you reckon your resistors stop this?
it did'nt have any effect on the one we had. we reverted the resistors back to solenoids... but if the damage was done? I dont know. Swapped ecu's at the time and no change either, but I could'nt vouch for that ecu having issue/damage either. My best guess is another component/wiring causing this on a shared power line.... but we could'nt find it at the time. Spent many hours searching, and abandoned it as unecconomic to persue further at the time.
What's normal lambda voltage seen in vagcom?
I'll see if I can dig out the logic info behind the decision side of the ecu, and find what is all linked to the lambda circuit.. And what parameters trigger the b1s1 code, then possibly find out what it thinks is happening then go from there.
We're you seeing high injector times on the other Ibiza's you've seen?
