well ok since summer i've been rebuilding a B16A2 motor, and i'm curious what ecu i should use. A lot of my friends say use a 98 - 01 gsr ecu, and i was thinkin since my motor besides the head and block, are all mostly 99 - 00 si parts that i would get that SI ecu. I was told from a local shop that i shouldn't get the b16a ecu because its only meant for right hand drive cars .... so any advice would be good now.

 

Dont know if your running OBD2 or 1. Either way get a p28. if you got OBD2 you need the conversion harness.

 

why should i get a p28 ecu ... thats for the 92 - 95 motor. I'm runnin the JDM B16A isn't the fuel curve and vtec engagement and all that better if i get a gsr and put hondata on it .... this is all for turbo

 

A GSR ecu would be the last thing that I would get for that motor.

If you want a plug and play ecu, get a P28 that's been rechipped for a dohc motor.

If you plan on getting hondata, you're gonna have to get a P28 anyway. So, might as well do it now.

 

so just a plan old regular p28 ecu ??? i am confused why .... why not any of the other ecu's

 

Because a P28 is easy as **** to chip...it can be chipped easily for any VTEC motor, SOHC or DOHC

 

how exactly do you chip a ecu meant for a sohc into a dohc ??? i'm sorry i'm just lost and i dont want to end up buying the wrong thing

 

you buy a chipped P28...they solder a chip to the circuitboard that has a different program designed for your motor (different VTEC engagement, fuel curves, etc)

For instance...check out what EG6AJK has for sale: https://honda-tech.com/zerothread?id=430594

Search "ECU chipping" under archived content and you'll find a ton of stuff

Also, check out http://www.hondata.com

 

so i can find a p28 easily at local junkyards, what chip do i get then to make it into a dohc ??

 

EDIT: didnt know it was for turbo.

Yea p28 with Hondata all the way.

 

Kenji ???? wtf never heard of that. can i just send the ecu to hondata since i plan on turbo

 

thanx for the link, i'll do some background research ... you guys are awsome for explaining that stuff to me thanx
