obd0 to obd1 question

[slowCRXinPitt]

Hey guys, been a while for me on here. I've had my d15b vtec in my crx for over a year running obd0. I finally have the ecu and jumper harness and im ready to convert. My question is can i continue using my old manifold and tb? Is it a must that i use the d15b manifold?

Cheers, Vince

No, you will need the obd1 sensors and I believe injectors. But the manifold will be fine.

????....you will only need to get a obd1 dizzy and get rid the resister box and solder those wires :-)...what ecu are you using???make sure you ave one that wont look for a knock sensor

P08 ecu is what im running. so ill just use the obd1 dizzy. Get rid of the resistor box...uhoh... didnt know about that one... lol a little help?

eh, im a noob at 2am. Sorry

oh, and whats this o2 sensor stuff? I read that I can keep the 1 wire o2 sensor with the p08 ecu, correct?

Thank you very much, I do appreciate it, but it still doesnt answer my question about the 1 wire o2 question. Do I just leave it as it came in my si for the d15b vtec swap or not?

ECU is a 'small case' P08 (this will run with single wire 02 as thats what VTi/VXi came with). VTEC point is at 4800-5200 rpm (4800 @ WOT), while the rev limit (fuel cut off) is at around 7350 rpm. P08 has fairly leaner maps with more timing advance then the P28/D16Z6 ecu A USDM p28 can be used longest 4-wire 02 is used and you don't mind the slight performance decrease. But no worries it can be easily chipped to P08 specs.

Thank you rider, I have the p08 ready to go, so all is well correct?

yes....have any problems just aim me at yz125rider21...peace
