Wideband lambda - Innovate LC-1 alternative?

[Bobley]

I had an engine built a few years back and it was extensively tested on dyno before going into the car. The ECU was the DTA S60 and I initially hoped to use the LC1 but as testing went on it was found that the Innovate was drifting at high power outputs compared to the ETAS AFR sensor on the dyno. The builder was quite keen to send the engine mapped spot on so he went and sourced the NGK AFx system from the US. Ironically is appears to use the Bosch LSU sensor. I find it very responsive and easy to set up.

The NGK can use either sensor, of course you need to specify which sensor you want when ordering.

It appears until further testing that my LC1 has failed. It was calibrated to give 0v for 10:1 AFR and 5v for 20:1 AFR to work with my Canems ECU. After a winter SORN, removed from one exhaust and screwed into a replacement it appears to stick at 20:1AFR (5v) and occasionally flickers to 10:1 AFR (0v). I was quite happy with it for the year I used it but am now facing the purchase of another Bosch sensor......

Let me know when you find the best price for the sensor as I need to buy a replacement as well.

May sound obvious but make sure you handle the oxy sensor with kid gloves as even the slight clonk metal to metal when fitting will render the sensor useless no matter what brand of NB or WB sensor also make sure it powers up at the same time you start the engine (same feed for FP etc) otherwise there is a good chance of quenching/shocking the hot sensor with condensation/water moisture on cold start they dislike that too

Yeah, thanks, I made a catalogue of errors. At the end of last year I sorn the car. Had a chuffing noise which I put down to several loose exhaust manifold gaskets nuts. Took the complete exhaust off, put the sensor on the garage floor for 2 or 3 months. Fitted it to a clive f y piece and refitted the whole lot. Then when I started the engine I'd forgotten to plug it into the brains which I found out is another no no. So I've paid the price for being a numpty....

Sorted, it turned out that because I forgot to plug my O2 sensor in when I first started the car it reset / adjusted the calibration. Just re-calibrated the sensor and it works fine again. So I really can't complain too much about my LC-1 Innovate product, it comes down to a human performance error, or numpty on my part!
