    charge temperature

    never seen a charge temp approximation table does it need turning on with another menu

    charge temperature

    in the runtime value list under the fuel tab at the bottom there is a box saying charge temperature it gets to a certain temp then the box goes red . basically what is it and does it affect anything and where does it take a reading from as its not taking it from the iat sensor and i cant find a menu for it
  3. sorted it i had a stupid moment the fuel temp was working all along and the oil sensor was remote mounted so it measured pressure fine but as it had no flow its wasnt picking up the change in temp swapped a few sensors around and it seems to be working correct now thanks for the help
  4. dash reading is from a stack dash with its own pressure sensor i will go back tomorrow and remove one of the sensors for testing. its strange from cold they both start off reading around 10c then when coolant temp gets up to 80c it only gets to around 18c then i turned it off went back to it 20 mins later then the stack dash was showing oil temp at 40 and the bosch sensor was now showing 28 . but if you just let the engine run it wouldnt get past 20 and what else is strange is the fuel temp is pretty much the same as the oil temp
  5. with the dash showing 40c the resistance of the bosch sensor is 0.875 on the oil temp and 1.000 ohms on the fuel temp but I have no other way of measuring the fuel temp at those ohm readings the oil temp is reading 28c and the fuel temp is reading 21c. and voltage wise the temp is going high to low were as the pressure goes low to high
  6. will measure the resistance on them later when I'm at the car. I can't even say it's the wiring as the pressure part of the sensor shares the 5 volt and sensor ground and that works fine
  7. ive connect them to an temp 3 and an temp 4 and on the standard bosch ntc calibration there reading incorrect when the engine temp is around 70 they were both reading around 15. the pressure sensor part of the sensor is wired to an an volt channel using the 150 psi ti calibration and works fine i will try your calibration table and see what it reads then
  8. hello ive fitted the above sensor to monitor fuel and oil pressure and temp ive found a calibration page for the temp part of it and it states the values with a 4.6k pull up resistor how do i go about adding the pull up resistor to the wiring to get it reading correct. do i just use the resistor to bridge between the 5v and the temp signal wire thanks

  10. its now running the best it ever has when warm and apart from a bit idle oscillation here is the latest log and map with the above suggestions implemented. xr3 cold start map.pclr
  11. this is a log with all the above suggestions done its much better and stable when warm just hunts a bit warming up. excuse the start i forgot to rev it to turn the battery light out
  12. done all the above and its now much better when warm it still dances around when warming up but when warm its a stable idle ive block changed the fuelling when it was warm so will wait till it cools and take a log of it starting and warming up from cold and report back
  13. good spot i dont know why thats active ive never had that active or put any setting on in my life
  14. ok i will try it but when i changed the cam wire round the correct way it had no effect on the original problem it was still dropping to zero every few seconds it only stopped dropping out when i disabled idle ignition control. from cold it run fine untill it hit 26c then it started doing it so at a guess it appears its something that turning on based on temp. here is the log of when i first rewired the cam the correct way and ignition idle control still active.
  15. yes i will turn it back on and alter the idle ignition table but im also guessing my above idle ignition control settings are incorrect
  16. hello thanks for the help yes ign dropping has no been resolved by turning idle ignition control off. so it must be an incorrect setting in there somewhere. theses were the setting i was using do these look ok i will change the other settings as suggested and report back tomorrow
  17. ive got longer logs but it wouldnt let me post also the lambda not tracking the afr target is part of the problem. say its target idle is 980 i will set say a 4 square block were it will idle and set the number to achieve my desired afr. so say i put 20 in them 4 boxes to give the desired 14.7 but because it hasn't got a smooth idle. it then wants to drop in to the 750rpm box were that number to get the afrs right is in the 30s so its just wildly swinging the afrs so im having to alter other boxes just to get it running somewhat smooth
  18. turned idle ignition control off and it now runs much better the revs are still hunting but not as bad what other setting could effect this
  19. changed the cam sensor wires and its still the same strange thing is from cold it doesnt do it it only starts doing it when it hits 26c water temp
  20. ok will swap the wires and report back
  21. its even doing it without the engine on
  22. yes i will do it when i go back to the car whats strange it doesnt seem to do it from cold only when it warms slightly
  23. forgot to add the log here is one not the most current but same problem and a copy of the map again dont think its the current one but im on a diffrent laptop ive even looked back on my old vipec setup and it was doing the same on that
  24. jut looked at an older log and over the space of 10 mins or so i was getting 2 trigger 1 error counters and in the same space of time the ignition angle would drop to zero 60 plus times
  25. as titled im having a problem that when the engine warms up it starts hunting at idle and ive checked the log and the ignition table will be reading 18 and the ignition angle will be reading the same then the ignition angle will drop to zero for a second then return following the ignition map then drop again. i thought it could have been trigger related but im getting no trigger errors or any other errors . has anyone got any pointers where i should start looking thanks.
