i have a CTR b16b motor with a b16b ecu (pct) does anyone know where i can find the pin locations for this ECU? thanks (it's because i have an IACV problem) the b16a pin locations don't work.

 

I am going to assume that you are trying to put a '99-'00 CTR swap in a '99-'00 USDM Civic and you want to use the PCT ECU.

In order to make the IACV work you need to move the blk/blu wire at B8 (This location is from memory and may not be correct) to B23.

The '99-'00 SOHC Civics use a 3-wire IACV and the signal wire is located at B8. The '99-'00 DOHC VTEC Civics use a 2-wire IACV and the signal wire is at B23.

If you are trying to put a '99-'00 CTR swap in a '99-'00 USDM Civic and you want to use the PCT ECU that is what needs to be done.

is that true? cause i have a 99 or 00 CTR ECU in my 00 Si and have no prblems except running a little rich

 

It is true.

Notice where I said that '99-'00 DOHC VTEC Civics have the IACV signal wire at B23? Your '00 Civic Si is a '99-'00 DOHC VTEC Civic. Therefore, the IACV signal wire will be at B23 just like on the '99-'00 CTR.

kenji, i have tried b23. i ran a wire straight to the ecu. and the other to the ground. i've also tried a12, a13 and a14. still doesn't work.

 

First,

What year car do you have? What are you trying to do? Please give me all details so I can base my answer off of fact.

If you have a '99-'00 Civic DX or CX you will need to move the IACV signal wire from B8 to B23. The DX and CX use a 3-wire IACV. The orange wire is no longer needed and can be eliminated (be sure to tape it off). The yel/blk wire stays intact. The only change necessary is to move the IACV signal wire. Do NOT go grounding any wires.

The answer I gave is based on the assumption that you have a '99-'00 USDM Civic DX or CX and you are wanting to run a '99-'00 CTR ECU on a DOHC VTEC B-series swap.
