Dermot checked the various data files I sent from the first Freescan run. He found:
Baro and Map sensors do not read the same when ignition is on and engine if off.
At idle the Map is 0.19-0.2 at 1100 rpm, normally this is about 0.40-0.5. (2 or 3 Bar ?)
Lambda sensor is not working, no 0-1V swings at idle once sensor is warmed up. IAC valve is not working, should park at 170 and drop to acheive steady idle (40-70).
TPS sensor certainly does not go to 100% He was also not happy with the voltage output from the sensor, it is not linear and reproduceable in places
Dermot's recommendations:
New O2 sensor or check connections, get a Lotus one
Clean and possibly replace IAC valve
TPS sensor may also need changing, once throttle cable is set right
Check ecu again for any error codes
He expects engine should be running very poorly, fuelling should be terrible as it will be running off tables. Will check the throttle adjustment and check or replace all the sensors. Will then record the map settings again at the car's next outing.
[urgh]
