    Hope this will bring some D series builds alive! These videos are niche and don't generally do very well. If you want to support the channel, please consider showing some support below! 🙏

    Hi Mate, do you think this will work for me? I've got a D16W1 non-Vtec engine (for 2000 Honda Hr-V) ?

      How many plugs does it have to the factory ECU and how many pins on each plug?

    What did you do with your starter switch signal? Connector A pin 10? Is it not a necessary pin? Reading around I'm told the battery positive voltage is applied to the terminal when the car is cranking, and in doing so the ecu is told to increase the amount of fuel injected to help start the engine (since there is not poorvaporisation due to slow intake air)

    • @JCYT
      @JCYT  2 หลายเดือนก่อน

      What ecu is this? Nothing I touched involved the starter signal and fuel injection is handled by the haltech anyway

    • @secretchalolsian1481

      @ just calling back to your oem ECU pins that is shown in your spreadsheet, abbreviated as STS. Found on connector A pin 10

      @JCYT  2 หลายเดือนก่อน +1

      Have you set your timing with a timing gun?
      You can set ignition angle to 0
      Also - make sure you have your trigger settings correct

    • @devon1748
      @devon1748 2 หลายเดือนก่อน

      @JCYT I followed your sey up on your website the haltech d series preconfiguration wasn't even correct it was almost configuring the car like a b series and couldn't set the trigger to cam per b18-b16, your layout on your website is super helpful

    • @JCYT
      @JCYT  2 หลายเดือนก่อน +1

      ​@devon1748 If that's the case I would check if it using an OBD1 harness and pinout. But you may just have to pull the harness out and workout each wire 😅

    • @devon1748
      @devon1748 2 หลายเดือนก่อน

      @JCYT I haven't started the car with your trigger set up yet and I know my last tune tdc was around 20° so I will try all that within the hour. Only thing is I have my injectors wired individual instead of batch so I put it to sequential.
      I'll let you know thw report

    I have a question I think you would be able to help with, have you ever had g101 and g151 issues? Well only conclusion I came up with is because the car sits and dielectric grease is the wrong grease to use because it won’t sweat out condensation. I was getting like flash pop ups in data as error codes for literally every sensor, cleaned everything it all went away, car was fine for a year as it ran heat and there and the last year it has been in storage pulled it out yesterday and it’s back.
    I read about this, dielectric grease locks in moisture that’s in the metal and it can’t be passed threw that particular grease, I’ve tried carbon grease it’s not that great of conductor and theoretically neither is dielectric grease.
    What would be best to apply to this besides oil Evan tho I know oil will separate for the water

      I'm sorry but have never experienced those issues.
      To me it sounds like a sensor grounding issue.

    • @JCYT
      @JCYT  6 หลายเดือนก่อน

      Hi mate
      No i haven't but based on the pinout of the 1500, the process would be no different from a wiring perspective - just a lot more inputs and outputs available. I have the 1500 in my RX-7. Once that goes nexus, will convert the D16 to the 1500.

      It was set as bidirectional. I believe it was set at 200hz

    • @joshjosh7748
      @joshjosh7748 5 หลายเดือนก่อน

      @JCYT ah okay we might have different iacvs, I've got the 3 wire, d16y4. But it only works on bi directional or complementary, and I've gone off your wiring diagram but the wires have to be reversed for me otherwise the pid doesn't work and duty cycle is backwards. Sweet as if you post a shot of your settings and I'll see how they go on mine! My idle is nice atm but PID settings are off

    • @JCYT
      @JCYT  5 หลายเดือนก่อน

      Unfortunately i have no way of testing the jumper unless you can verify the d16y4 P2k harness is identical to D16y7. I have them for sale on my website. Does anyone in US make the patch lead?

    2:50 use a butane torch to desolder the stock ecu header, done it many times with the old OBD-0 ecus... and Hondata = 💩🤣 total waste of time and money nowadays, Microsquirt is alot cheaper and better if youre on a tight budget.

    • @JCYT
      @JCYT  7 หลายเดือนก่อน +1

      Yes that's what i said. I said the ECU is unreliable. At this age, the capacitors all need replacing amongst other possible fault. I've frequently had issues with Hondata S300 AND KPRO ECUs. This is not due to the Hondata chip or the car itself, it's the aging circuitry of the OEM board. Yes they can be repaired, but there are better standalone options on the market.
