OK, exhaust has been fitted for a couple of weeks now. Just some observations:
The exhaust seems to be burbling a little when off the throttle (ie very small backfiring). I am guessing its just running richer now? Havent noticed an increase in fuel consumption though.
The rear bumper is slightly stained. This, I guess, is explained by the car now running richer? When the car is first started (cold) there is a slight spitting of what looks like watered down oil (not oil, I imagine but water that built up overnight and become dirtied by the dirty exhaust??). This spitting quickly passes as the car warms up.
Also, at night, when under WOT, I can see "smoke" in the lights of the car behind me. Do you think this is, again, from a richer mix?
I *feel* like the car is every so slightly slower.
Just some observations I have had. My question is, can a cat-back exhaust cause the
ECU to run richer and can running richer cause the above symptons?
I will be talking to RMS about a new
ECU and full TB exhaust (the more I mod, the more I want to mod - you guys are right
) in the next few days.
Anyway, just wanted to give some feedback. If this post sounds negative, its not meant to be, as I am extremely happy with the note/service/worksmanship etc.
Also, I hate that I can't search for "RMS
ECU" on this forum (words are too small). I really want to get some feedback on RMS's
ECU work and want to search the forums before I post another thread....
Any feedback (or links to other threads) appreciated.
