Hi i was looking to get some help, i just finished a B18 ls swap in a 2000 si. Harness is off of a 99 civic dx. I have everything plugged in, tps, map, iacv, etc.. I have heard about the 2 to 3 wire conversion on the iacv but is that necessary for the setup i have? Currently has a stock intake manifold on it aswell with a 2 wire iacv.

 

Check your firing order.

 

Yes its necessary, not sure how the **** you plugged in the iacv

 

did u reuse the vtec head ?

what ecu ?

stock intake b16 or b18b?

 

Yes its the stock ls intake with a 2 wire iac. Not vtec yet, using a chipped p28

 

+1 You have to rewire for the IACV. If you somehow plugged the OBDII DX harness into a 2 wire IACV you're using the wrong plug.

Check all the sensor plugs by wire color. The connectors are not physically keyed, it is possible to plug them into the wrong things.

 

I'm scratching my head here... but Why did you go from a B16 (VTEC) to a B18 (Non-VTEC)? That seems like a down grade.

 

I bought the car as a shell for a pretty good deal and had a b18 ls laying around in my garage. Right now its kind of a budget build im trying to use what i got and make it run. Future plans are to go lsv. And i do have a jumper harness connected from my harness to ecu to make this conversion work.

 

motor lost compression on my em1 when I bought it, prev owner probably boosted the **** out of it.

I dropped in a b20.
