Hondata

Hello
A have a Honda Civic Ep3 2002 (EU) with PRC Ecu, k24/k20 frank, k20a cams, walbro 255 fuel pump.
K-pro serial is 14363.
Version software 4.3.5.
K –pro V3
i run the car in close loop. (i saw my o2 sensors wont work with my prc ecu)
I had this engine with no problems in my civic ej9 96-00. (no errors in hondata)

After I swap the engine and tranny in the EP3 I had the following problems.

1. I have the battery light on.
The wiring was check by a electrician and its ok, the alternator is ok, the battery is new.
Battery voltage stays between 13.8-14.2 when the engine is running.

2.I have the P0452 eror- Fuel Tank Pressure sensor low voltage when I star the car. If I delete the error it wont appear again that day.
Does my car has this sensor? I saw in other link that I can disable it? how?

3.After I drive the car about 50-60 min, i gradually lose power.
the more I go, the more I lose power, hardly gain 6k-7k rpm

please help
thanks

What calibration type are you using?

Is this a Civic Type R?

Yes, it's a Civic Type R.
For the moment i use the base map from Hondata. (k24-tsx-stock.kal)
After i made the ,,frank" , I didnt get to my local tuner to make me a calibration for my setup. (but certainly will not know what is the problem with the battery light - i allready asked him).

i also have another map (from a friend of mine), where the battery light does not turn on at all. neither when I put the keys in contact.
If you want, i can upload both maps when i get home from work.

thanks a lot.

these are the map i used.
k24/k20 is from my friend.

Have you tried disabling the multiplexor?

No, i didnt tried.
I will disable it today and see what is happening.
what should it fix ?

I just notice that that is a difference between the 2 calibrations you have posted.

I disable the multiplexer and the battery light doesnt turn on at all and the water gauge doesnt work with it disabled.

Now take the calibration you said didn't get the light on and enable the multiplexor and re-upload.

It.s the same thing.
The battery light stays on. :(

It appears there may be a issue with some wiring after swapping the engine. To be sure you should try the ECU in a known working vehicle.

ok.
i will try the ecu on another car.
the only thing i noticed with the second calibration is that the P0452 eror- Fuel Tank Pressure sensor low voltage, doesnt appear. (for the moment) :D
thanks for you're answers Spunkster.
