i have a 94 si with a b18b1 swap. i was told it was out of a 2001 ls

this is a pic of my ecu




its pr4 which i was told was obd0

my engine is(supposed to be) a 01 ls swap which is obd2

but it has the same plugs as the obd1 as shown in this picture

is this possible?

one more quick question

knowing what you know. what is your opinion on what gen this swap is?

The ecu looks obd-1, not obd-0. Obd-0 has a green plug, which yours doesnt have. The ecu probably came out of a 92-93 integra.

just look on the year stamp on the front of the motor. my frankenstein has a 97ls in a 90rs

x2 92/93 Integra LS

This guy is correct, this is an OBD1 DA9 B18A ecu, the OBD1 DC4 B18B ecu is called a P75, this one is labeled PR4.

im takin it if my ecu is obd1 then my I/M, engine harnes, dizzy etc etc... are also obd1? by engine is a b18b1 and the stanp on the tanny says it out of a 2000 ls

I thought the b18b1 was in older Integras.

^^^ no.... the b18b1 is the new engine the b18a1 is for the older model integras, but you can put a b18b1 in an older integra
