  1. Before you start on trying to find out if there is anything wrong with the calibration on a car that was working please ensure the Brake Switch and Clutch switches are working properly. It is quite common that they fail and the cruise control will not operate if either of these switches is on.
  2. Bosch Green 42 lb injectors work well on the scaled factory turbo injector data. Just scale it up so the high slope is around 48lb/hr. I have already posted up injector data that works reasonably well for the Siemens Deka 60s:
  3. It is on the list for a future release. And the DTC reading is on the list to be fixed as well.
  4. Hi Will, quick question are you using the latest beta 1.21 release available from your downloads page: https://pcmtec.com/downloads
  5. Hi effxr6t, You can reduce the number of parameters shown by opening a tune and using the View Menu: For example you could un-tick Professional, Workshop and OEM Areas and there will be a reduced set of parameters to edit. You should be able to do most of your tuning with these parameters. With regard to separating the Editor and the Scanner we are looking at that as an option.
  6. Will have a look but all modules will see it as it is broadcast type message. Also seems to be the only spot where the mk2 sends the cranking flag and is in BF, FG Mk1 and mk2. Have not checked the BA yet.
  7. Last byte has two flags: 0x01 = Brake Switch On 0x04 = Cranking in Progress Byte 1: rate of change of RPM vs time [maths equivalent d(RPM)/d(t)] Byte 2: Throttle Percent Byte 3: Pedal Postition Byte 4: Hill Descent Flags Bytes 5 and 6: Engine RPM Byte 7 is a flag to clear malfunction fault codes Byte 8 as above
  8. Nigel, Can you check on the FG2 if the cranking flag in msg 12D silences the alarms?
  9. Some Alarms like low oil pressure, seat belt warning and the lovely locking of the doors if the customer has that set up MK2 FGs do not have message 200
  10. msg 0x200 details (FG Falcon only): Bytes 1 & 2 : (Actual Wheel Torque in N-M / Wheel torque to Engine torque) + 512.0 Bytes 3 & 4: (Minimum Wheel Torque in N-M / Wheel torque to Engine torque) + 512.0 Bytes 5 & 6: (Maximum Wheel Torque in N-M / Wheel torque to Engine torque) + 512.0 Byte 7: Flags: 0x80 = Torque type is Engine Torque 0x40 = torque calculation includes losses (inertia,...) 0x20 = Catalyst protection active Bottom 2 bits are crank status. Still checking this but I believe it is: 0 = no crank, 1 = crank pending, 2 = low voltage cranking Byte 8: non 0 => key off timer in minutes (rounded up to next minute)
  11. base octane is correct but I think it is US specification.
  12. Pretty sure Ford tuned for 95 and up to 10% ethanol as well, putting in better petrol allows for more power but there are still places in Australia where you cannot buy 98 at all. The autooctane setting most tuners turn it off because they tell their customers it is tuned for 98, putting 95/91 octane in their tuned vehicle would lead to disaster.
  13. Ensure you have a good look the ZF calibration to the Sprint as well. The ZF and the PCM are in constant communication about torque and throttle position, ... Changing the torque table in the engine gets communicated to the ZF via CAN, if the ZF does not like what it sees then it will request torque cut or throttle cut in some cases. We have had customers alter the torque table and ZF will tell the car to shut the throttle no matter what your settings on throttle cut are. Also when the ZF requests a torque reduction of say 120Nm it wants to see that torque reduction figure from the engine.
  14. Finnigan, The stock TMAP and Boost sensors for the turbo Falcon are rated to 255 Kpa. 100Kpa is atmospherics pressure so 155Kpa of boost or about 22.5psi. It is more likely you are exceeding the voltage limits for the boost and TMAP sensors which will cause the clip. Raise these to 5.0V and see if that resolves the issue:
  15. And you can also turn the rear O2 sensor off by setting auF0011 to 0: Do not change auF0010 to 1 on a V8. Not sure why Ford does this but it uses the number of O2 sensors on a V8 to run certain V8 code.
