I have a 1997 Honda Civic Si with a B16a2, and sir Tranny.
I have a b18c1 ECU and I have engine light blinking like crazy. I can't connect it to the computer it won't read.
I told the car OBD reader under car description as 1997 Honda Civic, then 1999 Honda Civic SIR, then 1999 Acura Integra, still nothing
What can i do?

You probably have a JDM ECU or someone has converted to OBD1? Either way

97 SI? You might want to tell us where you're located, since your profile doesn't say. A "true" SI didn't exist in 97.

He is in Canada^^

OP, you need to figure out if you have an OBD1 ECU or OBD2. Do you have an ECU conversion harness installed? That would be a giveaway.

If the correct ECU set-up is in place, blinking CELs while the engine is on is either knock, or misfiring

Post clear pictures of your ECU.

Okay, the link you posted I will try tomorow, I think thats the way to check,
I didnt know these cars were obd1, i always thought obd2
Yes i am in Canada, and its a 97 Si
I do not have a conversion harness, When i got the motor and ecu and tranny, i told the person I need a plug and play one so i can just put it in without changing harness etc. And he gave me a b18c1 ecu and it just plugged in and worked(after changing starter -.-)
I will again try it tomorow with the loop etc

Your 97 Civic is OBD2a.

Again, what specific ECU do you have? If you don't know, post a picture of it.
