Hi HDDP,

I check in on the forum every once in a while - things seem the same, you, Woody and a couple others doing all the posting on race and performance.

I have been doing quite a bit of reading on fuel injection etc and invested a few GB pounds is some bits as I prepare to fuel inject a 1975 Toyota Landcruiser (straight 6 4.2l, max revs about 3,800 rpm!). Anyway one purchase was a wideband O2 sensor with display, heater control and voltage output. Seemed a useful purchase seeing as I will have to create all the fuel maps from scratch.

Back to Crossfires - do they run narrow or wide band O2 sensors, my thinking is if they run wide band it might be possible to fit an aftermarket unit like mine (www.vems.us) and then send the output into the ECU - after altering is slightly to create a AF closer to 13.5 or so. For that matter I think the VEMS unit might be able to simulate the narrowband output.

One complication with the 112 engine is whatever the sensor there will be two of them! (edit - not counting anything after the cats).

Anyway - all on the limit of my knowledge...back to my 135 bhp 4.2...I do have an Eaton 112 Supercharger from a Jag for it...wonder what the XF would make with that attached...
