You should get 14-15 without the a/c assuming your wife isnt the best of driver provided your car is tuned well.

@ mycarhasablower : I am driving the car for the moment. As, my wife has to complete her driving lessons before getting into this one.
I travel 40km every day office to home and in weekend the odo clocks 50-60km. Trafiic is not B2B adn it runs mostly on AC.
My dad has a '99 model M800, it gives us 14 in City with AC and gave us 17 with AC on highway(Hyd to Vizag).
Not sure sure why is this one give so low FE. as advised i will get it tuned once. Is there any thing else that has to be checked? So that i can walk to the service station with all checks to be done at one go.
Thanks in advance

I would suggest checking the fuel lines, clutch assembly and spark plugs - thoroughly.

10-11kmpl mileage is pretty low for an M800... My 2002 model gives 18kmpl on LPG, on highways, with AC on.

@ Silversteed: Thanks, sure will get them checked and post an update soon.

Thanks guys. I'll do an engine compression test and find out the reason why the coolant level goes down so often.

Ideally if there is any leakage, would it not be visible on the ground where car is parked?

I gave my car for service last week. Changed engine oil, gear oil, timing belt, spark plugs, oil filter, air filter, etc.

The car feels much better now.

I had asked for an engine compression test and the M.A.S.S. confirmed that there is nothing unusual with engine compression.

There was some problem with the connection of radiator fan which resulted in improper working. This could be the reason for over heating and coolant leaking. The is issue is fixed for now, I haven't had a chance to check this.

The mileage was very poor before service, but now I feel it's improved. I'm yet to confirm that.

Total bill came to 7.3K .

But my question is should the car get so hot? is it because the body of 800 is thin? No modifications of any sort have been done and the car is in perfect condition with 10,250 KM. I wonder what i should be doing to make the car a bit cooler. Obviously the sun control film which doesnt have any brand name isnt working. Please any advice and suggestions are welcome.

Drive safe.

chanakya79, I'd suggest you to take you car to service center and ask them to clean the AC ducts. I did the same to my 10 year old car 2 months back and the AC is much better now. Cost me 650 bucks for AC cleaning. Even if that doesn't satisfy you, go for a better sun film brand including the front windshield. This would set your poorer by around 8K, but it's really worth.

Jaizcrzy, give your car for servicing. You may need to filters, oils, etc. This would definitely solve the problem. Also get the wheels balanced and aligned. Check the brakes as well.

Keep revving.

@josejoseph : Thank you for the inputs. am back today after a 10 days vacation. Will check the above and update

Guys, due to poor illumination of headlights in my M800, I'm planning to go for aux. lamps in my car. What I have in mind is something like this:



Fix the lights on the bumper. I've narrowed down on Hella Comet 450. But the problem is that when I took the car to a fabrication shop for welding clamps, the workshop guys were unwilling to do the job as they did not find any suitable place to weld the clamps. Can any one guide me on mounting the clamps on the body/chassis to fix the lights?

Is it possible to directly fix the lamps onto the plastic bumpers?

Thanks in advance.

Regards,
Jose.

@ Jose the lamps cannot be directly fitted onto the bumper. There should be a metal base that can be bolted on for the lamps. You need to have another metal rod( something like a ruler) placed under the bumper so that the lamps can be bolted onto that metal rod. I suggest you look at the space on the bumper below the front indicators for the lamps. That will not restict the airflow to the radiator.

longhorn, I do not want to place the lights below the indicator/number plate level as I fear water logging or damaging of the units.

Re. the metal base you have mentioned, how is it connected to the car chassis/body? Any pictures or diagrams on the install?

Please help.

- Jose.

[longhorn]

The metal base need not be connected/welded to the car's body. The base is there only to enable the lamps to be bolted onto them and hold them in place. The bumper will support the metal base when the lamps are bolted onto it. The metal base should have two holes to align the lamps and pass the bolt(that will hold the lamp) through them. It can be placed on top of the bumper too. I mentioned below the bumper for aesthetic purposes alone. Unfortunately I don't have any pictures. Just make sure that the height of the additional lamps is less than that of your headlights else you will be inviting trouble.

Thanks once again longhorn. I'll go to a metal fabrication shop and get this done.

I believe it's illegal to put aux. lamps above the HL level; there is no problem to have the lights in the same level as HL.

Thanks,
Jose.

Sorry for bumping an old thread. We have one MPFI M800, which has some issues with ECU, the fuel pump is not working. Seems we have to replace the ECU. My father being an old school person, we are thinking of removing the ECU and fit a carburettor (convert fully to the conventional type). Is this practical and is there any risk?

Thanks in advance for any kind of input!!

[swiftboost]

@ glomus123 - Yes, you can convert your MPFI M800 to run a carb setup. Having said that, I think it would be easier to fix your present issue rather than going for a carb swap.

Its not very often that the ECU goes bad. Even is it does, it may be the smaller things like the resistors/capacitors etc and not the main processor/s in most cases.

Thanks a lot for the info. If it cant be rectified with any minor work, I am going for changing to Carb.

With thanks and regards

@ glomus123 - MASS may not be able to fix the issue if its ECU is at fault (other than replacing the ECU). Im sure someone here on the forum can suggest you a place to repair ECUs.

I have been able to salvage quite a few ECUs in the past except for cases when the ECU motherboard/ processor/ other vital components failed.

Getting to run the M800 on carb shouldnt be difficult once you have all the hardware in place.

Thanks again!! Unfortunately that is a problem again. MASS is not able to fix the issue, and my dad couldnt find a place to do it. Some info about any shopw who can rectify this issue in and around Kerala / Coimbatore will be much much helpful.

Thanks in advance!
