I swapped a jdm d15b into my 96 hatch about 2 months ago and it been running like *** since. It bogs down really bad under 3000 rpm and hesitates badley above 3000 rpm. The only code is code 20 (eltrical load detector). I am using the engines original computer the p08 with conversion harness. The p08 uses a one wire 02 sensor I am using my original 4 wire 02 sensor. By using 4 wire 02 sensor would this cause my car to run like **** if the ecu is suppose to reading a one wire 02?

Things checked/changed already:
Plugs, Wires, fuel filter, timing, injectors, distributer, fule pump, fuel preasure.

Also: Sometimes the car runs good, it isn't a constant problem. But it genrally runs like ***. And I am buring fuel like a V8

Thank for any suggestions.

 

get a p28 ecu and run that with the 4 wire and that should do it. why are you running a p08 with a vtec motor.

 

if i recall, you should be able to use either a four or a one wire sensor with the P08... i think you have to switch something out??? sorry, i remember reading it in a post awhile back...

P08 is the correct ecu for that motor

 

Bump for anyone who knows the 02 fix. Do you guys really think this is making my car run like complete ***?

 

airight I decided to pull the code again just for fun and I got a code 3(map sensor), code 10 (IAT), and code 14 (iavc). This is somewhat good news as in I know where to start solvong my problem, but now I have 3 sensors to fix$$$$.

Which sensor would be the most important to fix when it come to solving the bogging and hesitating problem. I would guess the map sensor. Suggestions from others appreciated.

Also with all these codes I guesing thats why vtec never kicks correct?

 

I am currently having the same probelm just tryin to get my car in working order running a p05 on a z6 and the damn thing shuts off after it runs for about a min. I will be trying a new ecu to see if that is the problem. ill let you knwo how it goes

 

bump for more suggestions

p08 is the ecu that came with the jdm d15b thats why
