  1. Thanks for that but i can't seem to open the file was it for the G4, not the G4+.
  2. Has anyone managed to mimic a Davies Craig EWP controller without using loads of aux outputs. Is it best to keep a thermostat. I have removed the one from my 1uz engine but do have a spare inline one.

    Idle control

    That seems similar to what i get but the FP regulator is set to 3 Bar. Is there any way to prime the pumps with the use of the timers.

    Idle control

    the only reason for dropping the FP that low on tick over is that the fuel pressure regulator, through manifold depression, does the same. The pumps can flow 660 lt of fuel per hour which is far too much unless at max boost and revs. The fuel was getting quite warm and pumps drawing too much current when they didn't need to .

    Idle control

    Got another question, im using Aux 4 as a PWM to control my fuel pumps. I have a Solid State Relay SSR, to do the high current switching and its set at 1800 hz. This allows control of the pumps to lower the pressure at low demand. At present tick over @35% PWM, gives 30 psi of fuel and maintains a steady 4.5 V Its yet to be set up fully but what would you recommend to to use as the "Y" axis on the PW table. At the moment its TPs % but i thought it might better to either MAP or % of the fuel table while keeping the "X" axis as RPM. I also need to control the Electric PAS pump, I do intend to use another SSR but could the ECU be used on the low side to control it again PWM.

    Idle control

    Im trying to set up the ECU for idle control with a 2 wire solenoid but cant seen to get it to maintain a stable tick over. Any ideas.

    fuel nalues

    Just trying to set the fueling on the ecu. The master fuel I know affect the whole map.and the value in the fuel table cells is a percentage. If the Master fuel is set at say 7ms and the fuel cell in the table is 50, does that mean that at that setting the injector will fire for 50% of the 7ms 0.0035 seconds. Knowing the basics of how the fueling figures work and correspond to each other and real life numbers will greatly help me map the car . This would also allow me to change the Master setting and have an accurate guess what effect this will have on the fuel table,. plus knowing the AFR will allow me to predict the correct number for all the cells before it goes on the dyno. Thanks Steve

    INjector Setup

    thanks for that is has made a difference. If the master fuel setting is is changed by one what is the equivalent in the main fuel or what proportional effect.

    INjector Setup

    Trying to set up the injectors with the ECU. I have a set of 1050 ASNU injectors and trying to find out the nearest injectors in the pull down menu. I have the injector/voltage i think that the same as dead time on the ECU, is the nearest the Bosch 1000H .http://www.asnu.com/static-downloads/injectordata/ASNU 1050cc VC 3 BAR.pdf

    Bigger Injectors

    Thanks for that. I have put "4 ms", the lowest value for master fuel, but its not low enough as the AFR is at 10. If i put in minus value in the "master fuel trim " will that reduce it further.

    Bigger Injectors

    I have your base map for the 1uzfe. My engine has a turbo so we are fitting 1050cc injectors. As these are loads bigger than standard what the easyest way to get the engine to test run and tick over.
  12. Yes the Digital window states both D1 and D2 VVT Cam Position OFF. The engine runs it just show the fault. On the Digital Inputs D1 and D2 on the ECU setting the pullup resister is off and that is normally when the sensor have a 5/8 or 14 volt input. I looked at the: Navigation: Wiring Information > Input Signal Wiring > Digital Input Wiring and it shows that the pullup resister should be "on" if the sensor is earthed. Or am i reading it wrong.
  13. The cam position sensors on my 1uzfe vvti aren't being picked up on my ECU. I have them wired from D1 and D2 on the ECU to sensor and then from the sensor to shielded earth. I notice the setting on the ECU that the pullup resister was off, on D1 and D2. Should this be on or should there be power going to the cam sensor. Thanks
  14. That's load of information. The main things I wanted to know the difference between the g4 extreme ( the old ecu which I have) compared to the new G4+. Mainly the difference in outputs.
  15. Hi, Whats the main advantages of the new ecu compared to the old one. Can it use the same ecu plugs (A,B) Is there any base maps for the 1uzfe engine.
