I'll have my D15B swap done soon. I dropped it into a 95 VX. I don't have the D15Z1. Anyway, it has the CX tranny and a D15B with a P08 ECU. I also have a P06 ECU (VX). Since the body was a VX, it's wired for VTEC and a 5 wire O2. Currently I'm using a 1 wire O2 (white wire in the harness). What if I were to get a Bosch 5 wire wide band O2 and run the P06 ECU? The D15B has the bigger cam and is tuned for performance.
The VX ECU is a P07 for clarification. The P06 is for the DX model.
If you have the proper ECU (the P08) then run that one. If you have the means and the knowhow to properly tune an engine to run lean then you could chip and use the P06.
I haven't seen any chipped honda ECU able to read the 5V signal from a wideband though. You could get a linear converter circuit and convert the 5V signal to a readable 1V signal for the chipped P06 though.
OK, P06 is for a DX. It can be chipped to be a P28, so therefore it's can't use the wide band O2.
Yes, I have the P08 and it runs fine on the 1 wire O2. My thought was that maybe the D15B could use the lean burn like a D15Z1 if programmed right. But if we can't program a P07 to match the D15B, then it would just run like crap.
I might play with it later if I can get the P06 chipped. pgmfi.org had all the info, but seems there's some kinda law suite with Hondata. Another source?
