  1. Not super fancy, but I use a math block to filter my speed signal with the average function (av). Works really well.

  3. The pressure compensation is non-linear and applied to the pump current before conversion to lambda (also non-linear) so it is a fairly complex relationship, generally done with look up tables. I suspect that RBR calulator linked above uses some simplified equation as it seems to give very optimistic results for the NTK sensor. They are typically about 4 x more sensitive to pressure than the LSU4.9 in my experience. For the LSU4.9 there are a few slight variations of the pressure compensation curve but this is the one that is generally used from what I have seen: So a couple

    IS300 can issues

    Hi, I have a IS300 myself, although not running the xcessive/panicwire pnp kit, I repinned my loom to the right headers to suit. I don't have any issues.. It sounds like to me that the MPX isn't wired correctly on your loom and/or not going to where it suppose to go. Since you are using the IS300 2JZ loom, and using the panicwire patch loom, Check out pins E-5 (MPX1) and E-12 (MPX2) on the Link/Altezza header side loom, , make sure they are connected to the body loom and goto the body computer. On the IS300 loom side they "should" be connected to E4-21 (MPX1) E4-20 (MPX2). I'd unplug the

  6. Yes, Ethanol, APS, and a whole lot of statuses from cruise/traction/antilag etc have been added on to the end of the existing generic dash stream. This means older devices (G4 etc) are still compatible with a dash that supports the new modified stream. The detail is in the help file. You should pass it on to them - I believe another user already has but I assume the more that chase them the better your chances.

  7. Probably my biggest annoyance with the Link software so far is the fact that if I change the load or rpm break points on one table (for the sake of argument fuel table 1) - I typically would like the option to use these same axis settings on the timing table 1, or fuel table 2, etc. If I enable per cylinder fuel trim tables and per cylinder timing trim tables - having to reselect and rescale the axis on each one which is another example of this same hassle and takes extra time. If there were an easy way to copy axis settings from one table to another or when changing axis of certain tables s

  8. "Home position" or "zero" for the intake cams is fully retarded against the mechanical stops. Anytime the solenoid is not energized the cams will be at home (typically anything less than about 35% duty cycle). Typically at idle and at high RPM they will be fully home. Once you apply more than about 40% DC to the solenoid the cam will start to advance (More DC = advance faster). I dont know what the max advance is on the EJ's but most engines from that era would allow 45-60deg advance (crank deg) from home position.

  9. You will need to change your relay's coil feed to be ignition switched, rather than permanently powered. This way, the ECU will still pull to ground to activate, but when ignition is off, the coil cannot be energised, even with the ECU defaulting to grounding the outputs.

  10. Thank you for fixing the Cruise Light functionality, I'm hoping that should help with being able to change to a different E-Throttle Target Table to minimise speed overshoot when accelerating. Plus I can have a light on the dash, too!

    Fuelab Pump 92902 PWM

    Update... Everything seem to be working correctly as far as the fueling is concerned. I did change the Hz to 1000 like was recommended. I also am now running the FP in Open Loop... for now. Lastly, I did update the firmware. The "FP Speed (%DC)(%)" does still show the "reverse" for me. As the actual FP speeds up, the "FP Speed (%DC)(%)" goes down. Min DC clamp at 30% so "FP Speed (%DC)(%)" shows 70% and ramps up to 100% by 30% Inj DC.

    Random questions

    Early models had a 6 tooth crank and 7 tooth cam. Later engines had a 36-2-2-2 crank and there were various options on the cam. But the common cam option is what we call "V7-9" which has 2 teeth on one of the front cam sprockets.

    USB PORT SHORT

    Only CAN2 port has 12V on it so you must have the USB cable plugged into the CAN2 port. The USB port is quite clear, it is on the underside of the top board and there is a big arrow pointing at it.

  23. Ahh that would make sense. The error counter incremented by 2 almost every time I cranked the motor. I didn't see the error this last time when I actually got the motor to start and idle. Thank you for all your help Vaughan. Having your tune to compare to helped me find a lot of little things I missed the first time I setup the Ecu.

    Check your USB connector is not plugged into the CAN port on the board of the ECU. This will cause a short on laptop.

    g4x fury ports closed

    On G4X, it is different than G4+, you must go on a function and then assign a pin/port. If you want your analog volt 3 to be your TPSn then go to function TPS and assign it to AN Volt 3 for example the tables you show is only an overview, that's why you cannot change them.

If you're eyes aren't that great like mine and you still want to use the entire screen I found this: https://surfacetip.com/set-custom-resolutions-on-surface/ Option 4 using the "Custom Resolution Utility (CRU)" was the Magic Wand for me. With the resolution set to 1440 x 960 I can finally see everything properly without the scaling issues using the default / recommended resolution. I've attached the default layout adjusted for the 1440 x 960 resolution Default 1440 x 960.llfx

    Overboost suggestions

    Stage 2 is P&D control, stage 3 is P&I. Stage 2 intent is to control the final approach to target, if you are overshooting target it is usually stage 2 settings. Stage 3 intent is to keep the boost on target once the target has been reached. In laymans terms, Proportional is how much the ecu adjusts the DC based on how much error there is. Too little P = slow to reach target(or never reach target), too much P = overshoot or oscillation. Derivative effect I find easiest to imagine as how quickly the ecu pulls back the DC when the boost is getting close to target (kind

  30. Update: For what it's worth there is an o-ring in the VTC gear valve cover plate and sure enough the oring was damaged. I can only assume that I messed it up during install. I installed a new flat rubber oring, fired the car up and VTC is functioning on both sides. Issue: Fixed:

  32. Just to update this one. M & W verified that the boxes can run two of their CDI coils and the Haltech CDI ones wired in pairs on one channel to accommodate a V6 twin plug application but if more spark energy is needed would be best to add the additional pair of boxes or use one of their new Pro-16b S4 boxes which can handle high speed two strokes applications as well.

  34. Trim should be negative I believe if you want to pull boost duty out. But if you put -50% you will remove 50% of waste gate duty. If you target 70% duty then the remaining duty in 2nd gear will be 20% and not 35%.

    dual fuel pumps

    Set the 2nd pump aux output as GP output, then give it conditions, I would suggest one of the conditions is the main pump is running - then the second pump gets shut off with the first for safety. Example below, main pump is on Aux 1, 2nd pump is on Aux 2, so second pump will come on above 120Kpa provided main pump is on.

  44. Would it be possible to have an option for the the mixture map function to take into account correction made from closed loop lamda? I like the idea of having CLL running as an added safety margin when road tuning and it would be good if the mixture map could look at what corrections are are being made to make permanent changes to the fuel map.

  47. You can already swap ignition tables and/or add 4 & 5D ign overlays and swap between 3 DBW tables based on CAN messages so that would likely cover what you ask. Is that all he wants or is there more to it?

    sensor cross reference?

    For temp sensors there is a bit of info in the help file page: Technical Terms and Reference > Sensor Calibrations, but at lot of the time it just comes with experience... For the oil press/temp, I suspect you have a PST-F1 (not the PST-1 map sensor?). These use a common industry standard calibration. Set the temp input to "Std Bosch NTC", set the pressure input to "1000Kpa TI sensor". Factory water temp should be "Std Bosch NTC", a quick way to check is measure its resistance at room temp (about 20°C), it should be near 2500 ohms. General motors generally use the "Delphi A

  50. you should contact the realdash developer to get it addressed, you can find the datastream layout in the link help file under "Technical Terms and Reference > Communications" where it states DI1 through DI6 speed streams are transmitted in KPH. Gear position is also sent in the stream so it's up to the developer to get it sorted, not Link Support
