whats the difference between obd0 version of the JDM d15b and the obd1? besides the obd0 and obd1? anything different performance wise? and does it come with a cable tranny (obd0)? I was going to put this in my CRX HF, If I get the obd0 version can i use the same Dizzy from the HF or get a SI one? I wanted to get a SI ecu and chip it for vtec and get it programed for the turbo. or should i convert everything to obd1 and get a p28 and program that? cause from what I read keeping the resistor box is good when doing a turbo set up. is that true? That reason and Im sorta lazy to do a obd1 conversion and buyin obd1 stuff. And about the tranny can I use the d15b's tranny with HF axles and hubs and all that? I got more ?'s but this seems like a lot already

Thanks

 

i don't think the JDM d15b that we are all familar with came in obd-0.

 

i think he's asking is it better to convert it to obd1 then to keep it obd0?

Basicly ya

 

then yes it's better to convert to obd1 for tuning purposes

 

and are all years of the d15b stage 3 vtec? or is it a specific year?

 

i'm not completely sure of the years but mine isn't a stage 3 vtec

 

what year is yours? and I think to make it work you have to have the VTi ECU or whatever ECU goes with the d15b, it is said the d15b gets 54mpg stock, what are you getting? you probably modified yours but so am I, so i just wanna know

 

obd1 D15B is better for ECU 's and no not all D15bs are stage 3 vtec, mine is just VTEC lol
my car gets about 18 mpg because its running rich. but since i am obd1 i dont have the flashing light on my ECu to check the code its throwing, so not sure if its a map sensor or o2 sensor.

 

from your experiences, is the d15b all its cracked up to be? I can get the motors for $180 complete so I was gunna get one for me and my brother, but I was gunna turbo mine. theres other ways to check for the ECU codes then the flashing light on the ECU, im sorta lazy to type it all but its pretty easy

 

well if you get a ecu jumper harness from rywire then you connect the orange and blue wires and the check engine light flashes to show codes, but i think for the money the d15b is pretty nice, 130hp, im using the p08 ECU that's for that motor, but im getting a p28 since i am going to tune it and sell the p08.

 

the 3 stage vtec is very rare and that is obd-2 the obd-1 is just vtec thats the po8 ecu and jdm d15b vtec is a pretty good motor its a bang for your buck

This is what i posted because to many people dont know what they have
