So I swapped in a b20v(converted to obd1) into my 99 ej8 and everything was going good untill someone stole my chipped and tuned ecu... ecu was a po6, now I went out and bought another po6 that came out of a different b20v... now my problem is that I know have a check engine light and it's throwing out 3 codes.. code 2-secondary o2 sensor, code 45 fuel metering system and code 5 map sensor.

I believe the o2 sensor code is because the chip inside the new ecu was some sort of obd2 b20v/b16 base map so it's now looking for the 02 sensor which my car has but I think ita done.
My old po6 was full obd1 so no o2 sensor..

Now i can't figure out why the new code 45 and 5 are from? Is it because this ecu was tuned for a completely different car/set up so now my fuel/air ratio is way off and im
runmimg rich?
Also the car is now running rough at idle, bounces from 5000-1000 rpm and when I drive it for a bit and come to a stop idle just drops to like 100-200 ish
also at first start black soot comes out exhaust

Any any help would be appreciated


thanks

 

Your tune was on the chip inside the P06 ECU that was stolen... who knows what program is on the chip in the new ECU you purchased. You will need to get your new chip to your tuner that tuned the car before and have the the old program burned on the new chip... then you should be just fine again.

 

Exactly this^^^^. The tune on the ECU your using could be for different injectors, different map sensors, different dozens of things. This is why you don't go plugging random chips and ECUs into your vehicle. Do you have a chip burner? I would be more then happy to email you a basemap for your setup to use. If not, just take the chip out of the ECU you currently have, put it away. Hop on Phearable, XenoCron, AdvancedIgnition.com etc. One of those decent tuning sites and pay the $30 for a chip + basemap for your setup. Once you get it use that chip which will atleast get you started and running until you find/get to an actual tuner for a tune.
