  1. @koracing i have Link sensors with packaging that shows BSP and NPT.
  2. trigger 1 polarity is reversed. make sure trigger 2 is set to none or you will get no spark as the ecu is expecting a sync signal before it will try to fire coils.
  3. They sell both. They offer bsp and npt.
  4. You can also use the small port or GZE dizzy that has a 24 tooth wheel as well as a single tooth for sync.
  5. you can view the status of the digital inputs in the runtime value list by pressing f12 and scrolling left or right to the Digital inputs tab
  6. Have you configured the AC request digital input in PCLink? Sometimes you may have to verify that the DI is functioning as it should and may have to adjust a pullup resistor setting for it to work correctly.
  7. ive played this game too. Most recent round, the aem disc didnt fix the problem and actually made it worse. The solution was as adam described, needed new optical pickup.
  8. @driftae76I have had various ecus on my motor(autronic sm4, g4+ extreme, g4x extreme) they all exhibit the same behavior. Ive also had various versions of inlet setups(stock upper and lower, ported stock upper and lower, cable ITB, and dbw ITB) once again, all exhibit the same behavior. Its primarily a low throttle/airflow issue. I have purely used the individual cylinder correction on the leaner bank to bring it up to match the richer. And this is solely used at idle and very low rpm and throttle until the sensors began to match.
  9. I run 2 link CanLambda units on my car, but have had good success with aem x series units and ecotrons ALMs. I used to have a dual channel innovate unit, lord that thing pressed my patience.
  10. I had this same issue on my 1uz on the low end as you have described. I did use the individual corrections to "even out" the fueling off the lambda sensors as you have also described. Worked perfect. Numbers in the individual correction table is additional percentage added.
  11. Pretty sure youre thinking about this backwards. The ignitor grounds the coils at the request of the ecu. The coil wiring is +12v on one terminal and the 2nd terminal is ground signal from ignitor. Typically the ignitor will have its own ground, and the body of the ignitor is typically a heat sink and needs to be mounted flat to metal with some heat sink paste for thermal transfer.

    Lambda sensors of the bosch 4.9 variety can be wired direct to the ecu via the C Connector on thunder. Pins 3-7 would connector to bank 1 sensor and pins 9-13 would connect to bank 2 sensor. C 1 Main Relay + 2 Ign Sw 3 MES 1 4 APE 1 5 IPE 1 6 RE 1 7 Heater 1 8 Main Relay - 9 MES 2 10 APE 2 11 IPE 2 12 RE 2 13 Heater 2
  13. feed the turbo speed sensor into Digital input. It will read turbine speed. You may run out of resolution on the input and need to add a divider circuit. You can config ecu to do anything you wish with that info.
  14. Altezza plug in only has 7 ignition outputs if i recall correctly. So full sequential would not be possible with 1uz. There isnt any way to add additonal I/O for ignition/injection, but as far as additional sensor input, you could use the likes of an ECUmaster or Canchecked CAN i/o board to input extra sensors into ecu over CAN.
  15. I recently fought with dizzy issues on a Nissan Vg project. I got a local parts store reman unit and all was happy afterwards. The optical pickup was failing in the originally supplied unit, which is a common issue these days on OE units.
  16. For brake fluid level and Alt, I would just wire into dash to avoid consuming available I/O on the ecu. Alternately you can wire both of them to spare digital inputs on the ecu and have their status communicated over CAN to the dash.
  17. In my application, I ditched all the factory toyota electronics to use a crydom solid state relay that is driven by the ecu to vary pump speed. I have a wheel speed sensor on a non driven wheel fed to ecu for varying assist based off road speed.
  18. Id start with spark plugs. Whats the gap set at?
  19. @Adamw could you post an example of the math block necessary for this on the G4X?
  20. Pin 1 +5v Pin 2 signal out to Ecu An Volt Pin 3 signal in Pin 4 ground
  21. I pondered this quite a bit yesterday and Im pretty sure i have a mildly elegant way to accomplish this. It is going to be on a G4+ Thunder, so I'm kinda stuck needing it. Ill have the capacitor here today and will post a pic once i have it all assembled. Adam, do you think you could post an example of the necessary math block for filtering the fuel level on a X?
  22. @Adamw what would be the best way to bury this in the back of a 4 pin dtm connector?
  23. A few years ago I installed a wrx107 g4+ unit into a older chassis with 2008+ wrx driveline. The pinouts are the same.
  24. I would highly recommend the modelled multifuel equation over traditional for a flex fuel setup. Are you planning on running an ethanol content sensor? 2 sensors that are immensely valuable with these ecus in flex fuel operation are ethanol content and fuel pressure. Ive been blown away at the modelled equation with pressure baked in. Ive had fuel pumps fail and have been able to drive my car back home on about 10-15psi with no ill effects.
