Hi do any cars have fitted as standard a wideband lambda that i could remove from the breakers, i need one for my 1.8t to get it mapped christmas is here and all that so want to keep the costs down and get the car finnished also been told today im not getting paid till the 10th of jan or does anyone have one for sale
Edit - Looks like a standard ME7 controlled 1.8T has a wideband sensor pre-cat, such as Audi TT AWP code etc. One thread on here mentioning the LSU4.2.. http://www.clubgti.com/showthread.php?145027-Wideband-For-MegaSquirt-3 http://www.amazon.com/Bosch-17014-O...newCar=1&s=automotive&vehicleType=automotive#
Its the pre-cat sensor, not going to list every car with one but Nat's 2001 Leon Cupra for example has wideband and so you can view AFR via scan tool.
Yes, just found on Amazon of all places have a fitment guide for the LSU4.2 http://www.amazon.com/Bosch-17014-O...newCar=1&s=automotive&vehicleType=automotive# Looks like ME7 equipped VAG 1.8ts have them, as you've said. So presume, if scrap yard hunting, stuff like Golf 4motion (Also ME7) will have the same? I think the aim of the OP was to find out what he can nab one cheaply from ..
basically, get down the scrappy and look at VW, SEAT, skoda and Audi which have a lambda plug with more than 4 pins loads and loads of engine codes for them and its easier to just look in the engine bay to see what a car has then try to figure out the engine code
ME7.1 as fitted to a ARZ motor and early BDE 24v engines uses a binary sensor for EGO feedback ME7.1.1 ( Later 24v, VR5 20v and R32)and ME7.5 ( AUM, BAM, etc) use the 'planer' LSU4.2 wideband sensor. Around 60-70 quid new.
Right am i thinking that wide band has more than 4 pins, my plug has 4 pins but im told ill need wide band to map it (im using agu ecu)can it be done with my setup? confused now.
AGU (ME3.8.3) ecu is narrowband (4pin) only mate. It won't accept a wideband lambda sensor (5pin) as used on the later ME7.5 ecu's. Ways around the issue are either: >Upgrade ECU and loom to run the later ME7.5 system. >Use a tuner who can custom map the Me3.8.3 system. R-Tech seem to be market leaders for the ME3.8.3 at the moment, though I did hear Badger5 were in the process of getting an emulator to enable ME3.8.3 mapping.
If you want one for tuning yourself you need the sensor and controller (and gauge), if your getting it mapped on the rollers they will have a tailpipe sniffer (but fitting sensor in exhaust is always a better option).
Your set up will have a narrow band sensor. The map the vehicle the tuner will use a wideband sensor, in his equipment, to set or validate your fuel control. This is independent to your hardware.
You do not need an emulator to map these, in the same way I did not require an emulator to map my M3.8.1 VR6 say. But it does make life much easier when you start to poke calibratables.
