i need to remap my d15z1 just bought the car today and the check engine light is on because the 02 sensors don't work for the p28. Does anyone know of any chips that will remap the ecu so i can run the o2's again don't really wana **** up the engine

and i know i can go P07 but i dont wana do that just wana stick to whats there

chips dont just remap.
you need to get the chip reflased.
02 wont work for the p28?? you're gonna confuse people.
you want your p28 to work w/ or w/o the 02?
If you just need a reflash, i dont mind doing it for you. no charge, just cover the shipping.

i want it to work with the o2 sensor
but i am just wondering is there any way to keep the vtec thats on the p28 instead of going back to vtec e

the VTEC that's in the P28 is literally identical to the P07.
VTEC is a control line that energizes a solinoid that opens an oil gallery in the head.
the 12V signal is the same, it simply lines up with the fuel/ignition maps very differently.

the Z1 will sound louder and may even feel faster with a P28, but if you take actual measurements of the two, you'll see that the Z1 runs better with the P07.
likely what you are feeling currently is power dropping off before VTEC, then it picks back up when it switches to the high cam maps and cam lobes.
Also you're not enoying the higher mpg that the Z1 can deliver in the lower RPMs.

as far as the O2, P07 = 5-wire Wideband, P28 = 4-wire narrow band.
the two are not compatable with each other.
(unless you have a P07-L01 or P07-L02, which use a 4-wire O2 for the cali-emissions)


one other thought, P28 = around $100, P07 = around $40
if you have the five wire O2 in the car all ready, that's a pretty easy choice to me.

i have a p13 ecu with a skunk 2 chip and i was wondering how to remap it to take the speed limiter out and tune it and put more hp and torque in it?
