I have a nissan primera P11.
It's swapped with a W10 SR20det.
I'm using the W10 wiring harness but it's very hard to connect to chassis harness!
I want to plug my P10 harness but i think there is some diffrence between the ECU pinout. Is it easy to adapt? Where can I find any picture to explain ?

Is it easier to flash my SR20de ecu?

I did use my 00' rr G20 harness to fit the W10 motor.

-Under engine bay what wont fit; injector harness and connectors(better have the JDM one) but i think you can modify yours.
-Iacv wires not long enough (youll have to splice)
-O2 sensor(splice)

Some fitment ussues but it is not that much of a deal.

I also did B15 to B14 ecu swap.

Hope this will help.

Quick question about the ecu swap, were you able to keep your factory keyless entry system with the b14 ecu?

On the sentra I think you can.

I have a B13 91 SE-R with the Stock ECU.

I am running a SR20DET Avennir Motor with the stock ECU and a E-Manage Blue Piggyback.

My plan is to Swap the ECU for a Avennir ECU.

Few days ago, i do the experiment, but for some reason, the motor can`t rev after 5000 rpm. In this case, i used the DET MAF.

I scan the Avennir`s ECU, and it throws 2 codes: Knock Sensor and Ignition Signal.

I don´t know why that happens. Any help, i will appreciate!
