Hi... With the 2.41 ECU, there is no Lambda Target table, so the best bet would be to go for something like the Bosch Universal Oxygen Sensor (15733) narrowband sensor (other sensors are available!) if you want to be feeding the signal into the ECU. As this is a 'switching' sensor it is pretty accurate but not precise.

On the other hand, if you want a more exact figure than the narrowband sensor can give you, you can always use one of the many wideband Lambda sensor kits available, that comprises of the sensor, loom and gauge. You can then use the gauge a your tuning aid rather than PC logging the ECU for results.

BR, RickS

Have landba any function in the ECU so it controls nothing or you can just remove it

Do not know what it might be wrong with the car it does not go well at low speed the jumps and jerks at two gear a little gas 25-60 km / h runs just fine otherwise. thought it could be lambdan which did not work.
I can send the mapp to you to see if there is anything that is not right

You certainly can tune the motor with the narrowband features in the ECU but they won't be as accurate. You can map the engine with an external sensor (not connected to the ECU at all) and by setting an internal ECU option (Ox FB Rate) to '0' and the ECU will ignore and Lambda completely.

It is all dependent upon whether you are mapping this car for competition or you need to be MOT compliant.

PS... Send calibration to the Tech.Support (at) gems.co.uk email address and I will try to take a look. It is possible that your ignition is to advanced at low revs.
