That's perfectly possible on-road with the right kit...it's exactly how we (petrol) mapped the 740 Turbo. The trouble with pre-wideband cars is that you have no idea what the car is doing on full load unless you add a wideband (in the tailpipe, or better still via a bung in the downpipe). Assuming the ECU has it sorted it risky, in my experience. The Landi system I had had an RPM vs Load map which would need adjusting with the aid of a wideband. Obviously that's not an issue for something more modern (like the XC90) with a factory-installed wideband. cheers James __________________ VOC 300-series Register Keeper '13 V70 D4 SE Lux '89 740 Turbo Intercooler '88 360 Turbo Intercooler '84 360 GLT '81 343 GLS R-Sport '79 343 DL '70 164
