I went back and looked at my spreadsheet and the wiring diagrams and the coolant temp sensor does tie into the sensor grounds inside the ECU....so I'm not sure why I said it shouldn't be tied into the MAP sensor ground. Sorry about that, please disregard.RckyMtnLegacy wrote:I am still confused by this when the write up explains to do this:Legacy777 wrote:Check out my ECU I/O spreadsheet.

B48 pin 21 is for the coolant temp sensor and shouldn't be tied into the MAP sensor ground.
MAP ground (B48-5 ; Red) :: Merge with B48-21. B48-5 is used for the stock JDM EJ20G cat efficiency EGT sensor. Not having an the stock EGT sensor has zero impact on how the ECU runs. The EJ20G harness combines the MAP sensor ground with all other sensor grounds at B48-21.

I have also printed out the USDM and JDM pinouts and am going through each terminal to match everything up. I would like to run a couple things by you and let me know if I need to move this to my build thread instead.
Are these the same thing just worded different? Left is USDM pinout and right is JDM pinout descriptions.
Yes!I was thinking about this again and your picture shows a rising edge trigger vs. a falling edge trigger (Disregard my comment about the negative voltage above). So instead of going from 0v to 12v it's going from 12v to 0v. Is that correct?
I made it whit a small bulb what you can find in the dashboard.Where did you take your oscilloscope readings?
No.Did the engine run after you repaired the cam sensor wiring?
I repared the wire and the shield also, with a thin aluminium foil.The crank & cam sensor wiring doesn't take too well to be repaired due to the low voltages involved, plus the shielding.
Without the sensor they will run?Also, you could try unplugging the cam sensor completely and see if the engine runs at all.
In this case say the Hungarian people:My wife is Hungarian.
