My idle AC off only 7.8%...maybe mine throttle is clogged.

Ultimate FC monitoring.

Vacuum + throttle + fuel flow + instant km/l


I already bought a car phone holder, which my phone will act as secondary meter panel during my journey back to Ipoh tmr morning.

Yesterday back home 500++km journey by monitoring vacuum, fuel flow, throttle and instant km/L parameter, in order to get more than 16km/l FC, here is what i observed.

1. Fuel flow is mainly depends on throttle position. 18-20% throttle will yield speed @ 110kmh @ flat road with >16.5km/L. Fuel flow shouldn't more than 110cc/min. This apply on BLM manual, quite sure 4AT impossible to achieve this.

2. With constant throttle rate, up hill will make vacumm decrease, but fuel flow will remained the same. Do not increase throttle if u want to save fuel, but it will make u loss speed about 15-20kmh depends on slope.

3. As mentioned hundred times before, our aircon compressor is for truck use, each time kick in will increase 2-3% throttle rate, which in turn decrease instant km/l until 13km/l. Before that i thought during highspeed aircond will be less influence on FC. So advice during long cruising, always set temp to warmest or drive during morning time, key rule is minimise aircond usage.

4. 20km/l is impossible for Saga @ highway cruising. Unless u down hill all the way. Last time i mentioned 80kmh will yield 22km/l is wrong, becos that time maybe i let go throttle abit. For trunk road, fastest u go, better the FC, anything less than 80km/l will yield less than 15km/l no matter what gear u engage.

5. Our highway seldom got flat road, majority are sloppy.

So for yesterday journey i nearly achieve 16.5km/l with 110kmh cruising, and failed by my sohighness to reach KL @7am, heavy rain + heavy jam @ sg besi to jalan istana, saw the average drop from 16.2km/l until 13km/l after jam for almost 50 minutes. End up whole journey 15.6km/l only.

Happy Chinese new year and enjoy traffic jam if u go back home town today, always drive safe.

becos i stopped twice on the road, so torque pro will calculate as 3 trips, my 1st and 3rd trip is avg 16.2km/l and 2nd is 13km/l, 15.6km/l is where i pump back full tank. So i can say the gauge is quite accurate.

bro, i feel weird and shame to tt with stranger.

Lol, i use OBD reader from bro Mahihi la, pair with android phone, that's it...

tibai u guys dun know 年初二回娘家 meh...

Don worry back of the car la, it is unbelievable rigid. We are Saga, not buttless car.

so u think rear strut can save it by being compress? i dun think so...any car bang by lorry also will be like that la, i think only roll cage can save u from that.

When u saw someone be it car van or lorry tailgate u, just let them pass will do. I always do like that, i seldom let lorry and bus stay behind me for long time, either smoke them or let them pass, one of the FOC countermeasure, right?

Sometimes is luck la, can't prevent one. Last year my car being bang by Kancil when i stop in front traffic light, thats why i know how rigid our gaga butt was.

Today pump Petronas @ Ipoh -> pump shell @ Jalan Duta, actual FC 16.7km/l, OBD reading 16km/l. After that from Jalan Duta -> pump caltex @ Melaka Restoran Jejantas Air Keroh, actual FC 18.2km/l, OBD reading 17.3km/l . Both also refuel until the brim, can see the fuel can't go in anymore. Both journey also maintain 18-21% throttle, speed varies from 90-120km/h.

Maybe Caltex pump can get more with same price.

No, what i want to said is maybe caltex pump output more fuel compare to others fuel pump, not mileage better.

All refuel was done @ today afternoon, as i travel from Ipoh to JB. Even vaporized i don think it will vaporize for 1L.

Looks like ur fender wheel arc dented rather than front bumper misaligned.

Maybe some minor ketuk needed.

Yup, that one is check engine indicator.

Your problem seems common for BLM with unknown reason. Normally it will disappear itself or disappear after ECU reset.
