Summary of change:
What is the best location for wideband sensor in turbo-engine? Before or after turbo? Feature request : * Is it possible to autocalibrate the wideband? ** The VEMS round uses the LSU4 sensor R_Cal resistor (calibrated by Bosch), so it does not require manual calibration ** the LSU4 sensor connected to v3.x must be tested and calibrated in free-air (takes 2 mins, 1 min of which is the sensor heatup). Alternatively, the calibration value can be estimated from the measured R_Cal ohm, but proper free-air calibration is recommended. ** '''it would be nice to be able to start autocalibration with the sensor in free air'''. V3.x could then adjust calibration value to read 20.9% * Is it possible to show RPM on Round WBO2 or is rpm signal just for logging? ** yes, it is possible to show RPM on the bottom display (instead of EGT, set in megatune), in 4 digits (over 10000 RPM, 1st digit is hexa), 0..9999..10000..15999 (which reads as 0000..9999..A000..F999) ** note that the "toothcount" and multiplier can be calibrated, so the displayed unit can be km/h or mph (wheelspeed) or other unit ---- Succesfully installed V3.3 on Mazda 323 Turbo. Stock engine 1800cc Stock turbo boost 1kg Big intercooler stock injectors Great result.

Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
