I had an innovate LM-1 in the XR2 to get the lambda reading for the mappable injection. Always had problems with lost sensor calibration and lost output programming. It's a known problem but looks like innovate isn't/wasn't able to cure it. Many others using the same injection had the same problems. I use aim LCU-one now and it's fine. Zeitronix units are cheaper and seem to work fine, also.
