Hey all.

First of all I must say, that in my Colt I don't have all Evo - sensors (without them car works great - see in sign this car), so I have still and still displayed few DTC's codes, which are coming back every time after clear.

P0037 - rear o2 heater ?
P0462 - fuel level sensor
P0441 - evap ?
P0183 - fuel tank temp
P0443 EVAP System Purge Control Valve circuit.
P0446 EVAP System Vent Control.
P0090 - fuel pressure

Now: can I just disable circuits, that are responsable for this codes in perihery settings ?

I don't have:

- rear o2
- fuel level sensor (I have stock Colt sensor)
- evap and egr (they are removed)

Thanks !

 

Up

I just set up my hex periphery 2 as 0001 and all DTC's are just disapeared. I hope it is safe for my engine

Now I have only one DTC: P0183, so my question is: can I change FDA bit 11 to 0 ?

This is very important for me...

 

Nobody ?

 

In theory that should work. Try it out. You can always change it back/it's not gonna fry anything.

It seems like it disables all the fuel sending stuff. I am not sure if the ECU compensates for fuel temps or levels (I doubt levels).

Make sure to monitor your tune.

 

Thank You. Most important is that I am not sure if disabling this fuel stuff is safe anyway.

 

I'm sure the answer is in a previous post. Just search again and read through. Then log your car before and after keeping in mind your tune. That's what I do anyways heh.

It takes some experimenting and/or searching sometimes.

What ECU/ROM are you using?

 

I am using 88590015 v5.10 with JDM Map and direct boost control. I will try Yours advice today and report what's on.

Thanks
