After i installed a chip to ecu. Few days later my engine I start to feel lag between 2-3k rpm the rest of power is ok.

Power is coming stops and starts to run again soon hits over 3000 revs.

Is this could be my chip error or is it something else.

Also i think I am running little bit to reach because some time my exhaust shoots the sound on just 4k rpm.

Can it be my o2 sensors?

Could well be the chip cos as you say you put one in and then you started to have issues, can you borrow another would be the obvious way forward.

 

Also, have you a boost controller?

is this at full throttle or part throttle?

Yes mate I got blitz boost controler.

 

Its happens if I press little bit more gas, if i press just a bit it works as it should be. Could be not enaught fuel or to much?

if it's part throttle it likely to be the O2 sensors. Next time it happens, put your foot to the floor and you should find it's ok.

 

This is because when you go full throttle it ignores the O2 sensors

I just tryed to floor it and it feels the same. But definitely i am running to rich in fuel my exhaust keeps banding all the time.

can you get someone local to you to put conzult on it?

 

try unplugging to O2's and see what happens.

 

I see you're in the UK, there must be lots of people around there than can help.. lol... :)

My friend got conzult. Do you know what numbers is should show on each o2 sensor?

i don`t have o2 sensors :)

if its the full version then you will see both and they should both be pulsing up and down (at idle)..

 

if the value/s is/are fixed then there is a problem.

 

check connectors and wires before replacing the sensors.

 

 

but like phutumsch says.... you say it started after the new chip!!

 

where did you get it from?

who programmed it?

what are your mods?

 

can you put another in to check.... there may be nothing wrong with the O2's
