Is it true that once you bolt on extractors that the car will run lean? As I have seen multiple cars with them and not a problem.
extractors

» CMF MemberGood question, I've been running mine for four years approximately, what damage should I be looking for if its lean, I know you need a tune to get full power. My motor will be getting at the very least a timing chain if not more depending on a compression test.

» CMF Memberheres one.
with my skyline all that was need was an ecu wipe.
literally disconect the battery for 24 hours.
the car would thn lose its fuel map. drive normally for the next 5-20km and the car would re map it self to a degree.
i did this after installing full dump back exhaust and intercooler.
car was fine.
however i dont know enough about micra ecu's to know if this will work.
frank, ya there mate?

» CMF MemberRudy I was told if a car is runjing lean, it will only run lean for so long before it goes bang. So I think after 4years you should be safe

» CMF MemberI have an air/fuel gauge (just off the standard O2 sensor, not wideband) in my car and I run Maxim works 4-1 with a 2 inch and stock on the intake side. According to my gauge it doesn't run lean.
Will install my wideband one day and get a more accurate answer.

» CMF Memberi dont think our ecu,s have any long term fuel trim/self learn, and most members who have fitted piggybacks have had to enrich the midrange iirc (stock or modded engine)

» CMF MemberDefinitely runs leaner.
I ran in multiple track days and noticed no Pinging. = no damage to engine.
Extractors, basic 2inch exhaust and a Nistune.
Got a 20% increase in power.
Without a tune or some sort of increased fueling, extractors are pretty much for decoration only.

» CMF MemberWith a nistune can you use standard computer?
CMF_woohoomobile
» CMF MemberNistune is an added board to the ecu, it allows almost full tuning of the standard ecu,
CMF_Christopher
» CMF MemberHow much would I roughly be looking for that to be done?

» CMF Memberguy in melbourne does install an tune on sr engines. should imagine itll be the same on ours.
