hi,
my wife & i bought lynx 1.8 auto 2 years back. it's a 1995 model.yup...the FC sucks, it's underpower, idling not stabil. to reach 120kmh also is hard. but I did some minor upgrades, basically to get better FC, power goes 2nd. the reason we bought the car is actually to save cost on FC as my car drinks quite a lot.
This is what I did & we are now enjoying the ride!Good FC with more power unleashed. Yes it works.
1st I checked the spark plug. The car used NGK spark plug heat range 6...it's totally black in color...indicating rich A/F mixture...too much carbon.
so I rebuilt back the exhaust system, changed the pipe, the bullets, the rear box,except the stock exhaust manifold. changed to 2" pipe.
next, i get a cheap adjustable fuel regulator. checked the std fuel pressure was 35psi with the stock fuel pump & stock fuel regulator. Brought the pressure to 30psi with the adjustable fuel regulator.
Checked the plug, ok a bit but still dark. car feels lighter.FC still not satisfying.
I bought from a friend, a single button Apexi AFC. installed it and set it to -10%. then we're talking more power here! car easily reach 140kmh. 160kmh is also possible.
then i started to use the heat range 5 ngk spark plugs. a little at the hotter side. the plug burned a bronze color head.
later, bought from a fren the K&N drop in element.used for few months. i also threw everything that connects to the air fliter box, made a simple direct cold air intake...colder air, good for the engine to breath....gegegegege...
with that, 17" rims with 205/40 rubbers went in, the car is able to go 170kmh..a little hard to push to 180kmh. FC is satisfying.
Somewhere middle last year, I've decided to upgrade the piggy fuel mgmt to the Apexi SAFC blue screen. A fren sold one to me. Sold of the single button. Installed the blue screen. tuned it myself.
with NGK 5 plugs, it's yellowish to bronze.
even much better FC with better powercurve. felt the difference. still, 180kmh is slightly easier to push but that's the most. can't go anymore.
early this year, sold of the 17" to my bro driving sampan bpt. bought 16" wheels. Car feels much lighter.
Currently, we are happy with the car. Now my wife complains on the fuel price. but the car is doing somewhere 90km to 100km per 10 liters of petrol.
I got an idea from someone to check whether the O2 sensor is doing ok or kong already...if the O2 sensor faulty, that could also caused the high FC.
....i'm thinking of getting an e-supercharger for her...gegegege...just to achieve topspeed much faster...still holding on with the plan.
