Thread: gtir ecu or engine management

ok i am halfway done getting my parts for the gtir swap into a p11...but i need some advice on what engine management to use (jwt or stand alone like apexi power fc)
anyone who did this swap please chime in...
much appreciated

gti-r ecu is obdI. so unless you have a jumper harness it wont work.. your better off finding an obdII jwt the the program you want.

My buddy is going to be selling his calum basic from his P11that should work fine with your car.

What year P11? 1999 or 2000-2002?

Are you going OBD2 or OBD1?

If 2000-2002
If OBD1
1. Then your option is to make a step down harness or use an OBD1 Engine/ECU harness and wire it in to the P11.

If OBD2
2. Then get a 1999 P11 harness and an OBD2 tunable ECU Calum, Nistune, or JWT ECU. You will have to switch a few pins on the harness, JWT has instructions


If you are 1999 and are staying OBD2
1. Switch pins on the harness, and get an OBD2 tunable ECU.



There was no calum basics for P11, there is also no JWT ECU's for the P11. P11's at first where like 98+ 200sx/Sentra's. Where their ECU's where not daughterboardable. 2000+ P11's have a 32 bit ecu, which is a whole beast of it's own and there is no way to get a daughterboard on it.

sorry for the late update but i went with the autronic sm2 standalone ecu..... car is runing great will be upgrading turbo in a couple months thanks for the help all the same

Looks like Endless was digging a year back hoping for a sale?
