Hi,
It’s been a while my 206′s engine behavior used to change with any
variation in altitude – the perfomance was significantly decreased as
the altitude increased.
Checking the ECU using diag2000, there was always a fault described as
"STOP LAMP INFORMATION". Deleting the fault improved the overall
performance and changed the exhaust sound too! After 1-2days the fault
was back again.
Finally I replaced the MAP sensor, put the original sparkles back (I
had
put SplitFire 3 platinum recently)and deleted the fault. WOW! it seemed

to be flying for the first day…
Unfortunately the fault is back and the engine response keeps changing
everytime I start the engine. It’s even not stable in the same altitude

anymore!
p.s. I have SuperSprint manifold + rear exhaust in place. There is only

ONE oxygen senor attached to the manifold and no catalyst convertor.

Any help appreciated,
