Re: b18b1 obd1 to obd2 emissions help
If your inspection requires OBD2 communication, you will not pass with an OBD1 ECU. There are no exceptions.
The only code you SHOULD expect using an OBD1 engine is CKF, which can be easily remedied if you search for the CKF hack mod.
Otherwise all other codes indicate a genuine problem that will inhibit you from passing a smog test, which you need to fix.
In the future, try to use cleaner sentence and paragraph structure so people are more likely to read your thread.

Indiana Test Procedure
Depending on the model year of your vehicle, Clean Air Car Check uses different types of emissions tests. All vehicles receive a Gas Cap Pressure Check, which tests to see if a vehicle's gas cap is effectively keeping fuel vapors from escaping. Fuel evaporation is a major cause of ground level smog and a properly functioning gas cap improves gas mileage by preventing fuel waste.
The Second Generation On-Board Diagnostics (OBD II) Test is the most common test procedure and is used to test model year 1996 or newer vehicles. During this simple test, data is downloaded from the vehicle's on-board computer to check for emissions equipment malfunctions. An OBD scanner is attached to a connector typically located under the vehicle's dashboard.
The OBD check will be for all readiness tests are completed, no CEL and no pending CEL.

Re: b18b1 obd1 to obd2 emissions help
The OBD2 P75 will pass emissions on that engine if you do the CKF hack and fix all the other trouble codes. You don't need Vtec to pass emissions. You do need both O2 sensors active, all the purge/evap components, and all of your other sensors working properly (except for the CKF, just google it)

Ls/vtec b18b1 0bd2 emissions help
Is it possible to run an ls/vtec swapped engine, in my case a obd1 b18b1 with a b18c1 gsr head with a p75 ecu from an ls integra. Will this ecu throw a code for anything vtec related, or will it not search for it. This p75 ecu is obd2 and so is my car and harness is converted from obd1 to obd2. Any info will help.

running help emissions
Hey guys real quick question, is it safe enough to run a obd2 p75 ecu on my obd1 b18b1 ls/vtec swap? I know I won't have Vtec because the ecu does't have it, but will it cause any harm to the engine if i don't go above (rpm wise) where vtec would kick in?
