which ecu do i use for my b20 swap into my 00 si

 

If its a stock b20 block and head you CAN run a LS motor ecu but try and get the stocker B20 ecu for the OBD you happen to be running on your car.

 

so ur sayin i can run the ls one or it would be best to run the b20 one also can i use my original ecu????

 

You can get an LS ecu and chip it to have a bigger fuel curve because if you dont then you would have a 1.8 fuel map in a 2.0 motor and that is pointless.

thats what i figured but why not juss use the b20 ecu or my ecu i juss wanna save as much money as i can when doin this

 

It is best to use the OEM ECU for your OBD B20....hands down.

 

is this a good deal..... b20 installed with b20 ecu and the b20 for 1700 ??? 30k miles on motor

 

Is that with or without tranny.....

 

they are puttin my b16 on it

 

rip-off.....Hmotorsonline.com has them for 799 longblock.

 

how much does the b20 ecu run ?

 

Not really sure....good question.
EDIT: I had a chipped P28 for my B20/vtec.

 

is p28 the ecu name? for the b20 or what is that

 

P28 is for the D16z6....but can be chipped for various VTEC motor applications.

 

so if used a p28 then it would be good? or hmm i get confused

 

I don't think you can use the P28, because it's for VTEC engines only. Which I just

picked up from reading just now. Correct me if I'm wrong.

Ok....you need a B20 (which is NONvtec) ecu for the OBD 1 or 2 that your B20 motor is. Basically just find a B20 ecu that is obd2 (which I assume the motor you have is). What year is the motor you are recieving. And if you have a 00 Si then you want an obd2 motor and ecu for simplicity and for legality you want a 00 or newer motor...

Yeah the p-28 is for vtec engines, but it doesn't sound as though this guy is going to use his b16 head? who knows, he didn't say

 

ohhhh ok i got it all thanks a lot man

 

He is using his B20 longblock with a B16 head and he is asking if the stock Si ecu is usable for his new B20. I said it is not and needs to be a B20 ecu or at worst a chipped ECU that mirrors the B20 fuel maps...etc.

 

oh nonoonoonnononno........ not using the b16 head haha i jsut want the b20 alone with the b16 tranny thats it
