for some reason my ss lude wont let me redline.. whenever i get to just below 7 rpms and if i keep pushing it.. the car will start choking...my car is warmed up when doing this... am i hitting the rev limiter? if so why is it set so low... or is something wrong with the lude.... my friends ss lude doesn't even have this problem...

sometimes this is caused by the ecu retarding the ignition, or by lack of attention to maintenance of the motor.

many causes, including fouled plugs, low oil pressure, minor overheating, or a fouled up MAP sensor could be the cause.

need more info about the motor and it's condition to make any type of diagnosis.

how do you reset the ecu? and what does resetting it do and is it safe?

remove the ECU/backup fuse located under the dash on the driver's kickpanel then reinstall it.

or disconnect the negative battery terminal then reconnect... but you'll have to reset the clock and radio presets.

Thats one way to do it, if you do it that way, make sure you leave it off for about 5 minutes...

If you'd like to know the easier way to do it... s e a r c h.

show me why you have to wait 5 minutes, and i'll disprove you.

there's no capcitance to maintain the on-board memory once the memory backup power is removed.
