Walnut Blasting/Now Limp Mode Under Hard Acceleration

thezone135i · 05-08-2015, 05:38 PM

On another note, the engine still has a hiccup every now and gain, whilst idling. Usually after a long run and Ill be sitting in traffic and then engine does this quick jolt. Is this normal? I rekon its always done it, and its not serious like the limp mode issue but I thought the plugs n coils n walnut blasting would have cleared it up like a brand new car?

The n54 motors can be strange beasts. After a long run to Phillip Island once, I had this loud 'tick-tick-tick-tick' from the engine for about 30 secs. Never heard it again since. But you have to wonder...
Glad to hear your main issues are sorted. If you don't feel that the idle stumble is affecting the performance, then probably more a character trait of your engine

It's mandatory to have plugs and coils replaced at least every 15-20ks when running mode.

Coils every 15-20k kms will get expensive I would have thought.
I would prefer to keep a set as spare and replace when necessary.

I would say plugs every 25k and coils when you experience misfires. I would just do coils every 50-60k for peace of mind though.

It's fairly inexpensive if you can do the above yourself.

Noted!

I ran Cobb 4.1 std map, but wouldn't dare to run the aggressive map.

Aggressive is addictive but I would like to get a ptf tune to smooth it out more like stock. Just not sure how to co-ordinate the 4rd gear redline pulls in between maps. I need my license!
