Nistune Forums

This guide is to be able to allow the 99 P11 guys who have bought and chipped a Nistune 94-97 B14 ECU or plan to in the future also applies to 98-99 B14 guys.

This is going to be an on going guide but i'll start it off with a picture with instructions.

This is the pinout of a 99 P11 ECU (probably the most complete correct pinout you'll find on teh web period).



Heres is a 1994-1997 B14 ECU pinout:







There is plenty more to come.

P10 (94-96) vs B14 (94 - 97) vs P11 (99) ECU Pinouts

From the excel chart I made below you can deduce what pins you can eliminate and/rearrange from your engine harness if you have a 1999 P11 and use an earlier OBDII P10,B14 ECU for purpuses of tunning i.e. sending your ECU out to get nistuned or whatever, I think you will find this helpful.

Thanks we really appreciate this
