Sam259 Posted December 2, 2018 Share Posted December 2, 2018 Just fitted td04 and fitted a wideband and on idle it’s reading 11.2 running rich and then when you throttle it, it’s going up past 20 going really lean. Any ideas?? Quote Link to post Share on other sites
Padders Posted December 2, 2018 Share Posted December 2, 2018 Who the hell has mapped that? What wideband gauge and sensor have you used? Quote Link to post Share on other sites
Sam259 Posted December 2, 2018 Author Share Posted December 2, 2018 As far as I’m aware it hasn’t been mapped. Its a Bosch sensor and can’t remember what gauge Quote Link to post Share on other sites
Padders Posted December 2, 2018 Share Posted December 2, 2018 Are you sure it's a wideband sensor and not a narrow band? Quote Link to post Share on other sites
RobSR Posted December 2, 2018 Share Posted December 2, 2018 What’s the full spec of the car? It could be a whole host of things. What ECU? What AFR Gauge? Where is the sensor in the exhaust? Was it new or was it used? The more info the better and the better chance we can help Quote Link to post Share on other sites

The more info the better and the better chance we can help It was originally doing the same on the ct9 but now I’ve got td04 on it with decat and blitz front mount, so I’ve got fpr with gauge and running 3 bar fuel and I put the 430cc injectors in but still the same so I changed them back for standards for the minute and I’m on the stock ecu, I do have an emanage ultimate to go in but I wanted to sort the problem first before adding that. The sensor is at the end of down pipe and the gauge is prosport And the sensor was new appreciate it thanks Edited December 2, 2018 by Sam259 Quote Link to post Share on other sites

Sam259 Posted December 3, 2018 Author Share Posted December 3, 2018 Pretty certain I have Quote Link to post Share on other sites
akyakapotter Posted December 3, 2018 Share Posted December 3, 2018 imo just get the emanage on and let the mapper sort it out. Quote Link to post Share on other sites

So was the gauge and sensor supplied as a kit? Or have you used a different sensor? Im not familiar with prosport gauges but some widebands need clean air calibration also. Your instruction manual will say. Is there a leak in the exhaust near the sensor? This can cause wild fluctuations in your readings. Have you ran the car with the sensor in the exhaust before it was powered up? Again if the car is running with the sensor in the exhaust with it not being heated (i.e the wideband not connected to +12v and powered up) it will also damage the sensor.

The gauge and sensor were supplied as a kit there doesn’t seem to be an exhaust leak no the sensor had always been plugged in. Quote Link to post Share on other sites
RobSR Posted December 3, 2018 Share Posted December 3, 2018 Ok, you can recalibrate the sensor and reset the unit, i would try that first of all. The instruction manual tells you how to do it. Where you have you got the kit grounded too also? Have you got a link to the kit you purchased? Quote Link to post Share on other sites
