Hi All,


My 205 with a RFV engine seems to hit the limiter at 6000 rpm. (It runs out of go at 80 kph in 2nd - 1.85:1 with a 4.429:1 final drive on 175/65/R14s).

The Haynes book "Peugeot and Citroen Engine Management Systems" seems to pretty clearly indicate that the injectors cut out at 6500 rpm.

Could it be cutting out at 6000 rpm because it is in some sort of "limp home" mode? Or because I am using a SI (1.6L) fuel pump? Or is it just that different cars came with different limits? (My ECU is from a '99 306 Auto Convertible).

Regards,
Michael
 
My money is on the following, in this order (assuming there are no faults logged)
-Auto ecu
-Different software version/ecu version
-tacho is wrong
 
I've heard that on some modern stuff they drop the rev limit for the Australian market due to 91 grade fuel and operating conditions. could this be the case?
 
That's an idea, Dave. I wonder. Anybody?


I reckon it could be that the auto ECU is different. The tacho can't be wrong unless you are accusing me of bad mathematics... :D

Your motor produces its MAX power at 5500 rpm with max torque a lot lower, why do you want to rev it over 6000?
