p28 with jdm d15b?

[d15bsedan]

will the p28 ecu work with the jdm d15b? more so will the ecu control the vtec correctly, and does it have the correct mapping for the 1.5l ?

 

[AHHVTEC]

it will work but you will need a 4 wire o2 sensor

 

[d15bsedan]

so if i just get the 4 wire o2 sensor, i'll be set with the p28? and would you know how to wire the vtec solenoid

 

[AHHVTEC]

yea it will be fine and ready to run a p28 as long as you have a 4 wire 02../and yes i can run a vtec wire.. just run it from the solenoid to the proper pin out on the ecu

We are talking about the D15B with two VTec solenoids, right? I'm looking at the same picture.
I made another post proposing a possible solution. I don't want to hi-jack this thread, so just go here for any comments/concerns with this...

I don't think he's talking about the 3-stage motor. I think he's got just a regular OBD1 D15B. It's like a Z6 minus .1 liters of displacement...

Alright. Honda needs to have a better system for naming it's engines.

naa its perty easy

Ok, the D,B,K...15,16,17, etc at the beginning is straight forward. There is no certain designation in an engines code that says if it's VTec or not though. Then there are two D15B engines. If they had it more like D15V3 for the 3 stage VTec engine, and D15V for the engine that's essentially just a mini-me B7, then it would make it a bit simpler to keep all the engines straight. For the VTec-E engines, there'd be an "EV" in place of the "V". Then for engines like the different USDM D series 1.5 liter engines, we'd have D15B8 for the 8 valve engine found in older Civics, and the D15B7 would then be a D15B16.

That may not have made sense, but I'm trying to use some kind of logic for how the engines could be named.

well i guess after you learn them all it just seems easy

For the D15B engines, you could just specify OBD1 or OBD2. The OBD1 version is the one that's like a Z6. The OBD2 version is the one with the 3-stage VTEC.

JDM engines are tricky because they never have a fifth digit at all. A B18C in Japan could refer to any number of engines (SiR-G, Type R, etc.)...
