VVT-i Variable Valve Timing with intelligence. VVTL-i Variable Valve Timing and intelligence with LIFT.same principal , different terms ?
German loh......hhahhahahahanice name.. like Thanos. Thanos price VVT hahah
waaa.. sorry i didnt know..German loh......hhahhahahaha
The name is an abbreviation of the German words for variable camshaft timing: variable nockenwellensteuerung.
I think since your engine has cam profiling the dip is normal. That kinda power on a stock NA engine is pretty healthy. Looks like you did a good job overhauling. Whats next on the engine list?I tried two dyno, both dynoject.
One from Mpower, got 160 whp with worn engine after tuned.
After overhaul, when to D4 racing, first run without tuning I got 165 whp. Which means i gain 5 hp after overhauling my engine, which is logical. Finally after tune on the second dyno, the results are 180 whp.
Also a myvi 1.5L got 80 whp, factory rating 102 hp at the D4 racing dynojet.
So i think dynojet is quite accurate at the least.
I'm going to try improve my fc. Currently only at 7.5-8.5km/L. Change spark plug, spark plug cable, clean air filter and tuning already. I guess the next obvious thing is changing the oxygen sensor. So i bought one from china since i could not find compatible oxygen sensor at the spare part shop, and just fixed it yesterday. Will pump a full tank and monitor from today. Btw the sensor only costs me rm35 lol.I think since your engine has cam profiling the dip is normal. That kinda power on a stock NA engine is pretty healthy.

Dont forget to change the fuel filter too.I'm going to try improve my fc. Currently only at 7.5-8.5km/L. Change spark plug, spark plug cable, clean air filter and tuning already.

Mine is a 3 wire type. Where to buy the superlon? Maybe i will try it. How much improvement did u get?Dont forget to change the fuel filter too.
On oxygen sensor, its almost universal.
Older model have 2 wire for reading only. Newer model have 4 wire for heater as O2 sensor needs to be so hot before it can provide the most accurate reading.
Another way to improve fc and at the same time improve aircond cooling is to wrap the cold aircond pipping in the engine bay. Some here did that including me. Superlon is cheap. Your aircons will gets cool quicker, your compressor runs at shorter time which help reduce fc.
u can try ask hardware shop. most shop carry the round type for home aircond usage. i buy the sheet type as i used it for other purpose too.Mine is a 3 wire type. Where to buy the superlon? Maybe i will try it. How much improvement did u get?
O2 sensor shouldn't be too much trouble if it's new. MAF/MAP sensor and fuel filter might be worthwhile changing to new as well. The SR20 uses COP I guess? Then better COPs?I'm going to try improve my fc. Currently only at 7.5-8.5km/L. Change spark plug, spark plug cable, clean air filter and tuning already.

actually there's damn a lot of things you can do to improve fc.I'm going to try improve my fc. Currently only at 7.5-8.5km/L. Change spark plug, spark plug cable, clean air filter and tuning already.

Will changing thr maf sensor really help? What is a COP?O2 sensor shouldn't be too much trouble if it's new. MAF/MAP sensor and fuel filter might be worthwhile changing to new as well. The SR20 uses COP I guess? Then better COPs?
Your blm is quite good. I always heard of horror stories regarding the blm autou can try ask hardware shop. most shop carry the round type for home aircond usage. i buy the sheet type as i used it for other purpose too.
I can confirmed the compressor runs at shorter period and the aircond cools quicker.
How much improvement?
Its been a while (years maybe) since i calculate my fc as now i mostly ride and does not fill up full tank anymore when driving. I just used mt benchmark of RM50 should get me above 300km. If not then something is wrong or i drive like a lunatic. Car is BLM auto.
cop = coil on plugs, didnt know the sr20 had thoseWill changing thr maf sensor really help? What is a COP?
what happened? Everyone...Proton spend money to make
a) Waja cost = RM1.2 billion
b) Gen.2 cost = RM1.3 billion
c) Savvy cost = RM850 million
With that cost Proton should produce car like Camry, Vios, City but sadly to said ....................... then compare with Produa
a) Myvi cost = RM580 million
Based on that figure, cost lower but quality & performance 3x better than higher cost................... What happen?
