Slow indica

tsk1979 · 9th August 2005, 11:30

Hi guys,
My indica used to give mileage of 13-14 in city and have a top whack of 140(Speedo reading, actual around 132). After the service the mileage has increased to 15+ and the top speed is around 115(Speedo). I went to the workshop and told them that i dont mind the mileage drop but return the top speed. But after many adjustments they cant seem to get it. Is there anything specific setting which needs to be changed? I figure they have screwed up something with the air fuel mixture.

yeah ur car might be running on wot they call a "lean" mix of fuel n air. U want to make it "rich".

turbo_lover · 9th August 2005, 11:51

yeap..its running lean ..
take it to a roadside mechanic he will make it rock ...minor tuning required .

tsk1979 · 9th August 2005, 11:51

Nope, i am on diesel, therefore i dont mind the mileage drop

. As for the palio, the palio diesel is way too expensive. I bought the indica diesel for 3.5Lac. If i plan to spend so much i would rather go for the indigo

Sorry the intention is not to question your purchase & got the way you think about it.

Is this alterteration affect only the top speed or even the pick up? Will this tuning have any long term impact on the performance?

tsk1979 · 9th August 2005, 12:26

Hehe, no sweat dude. Actually it should affect the pick up too. My indica is currently jerky in hills which is a typical sign of lean mixture. The workshop guys seem to be die hard environmentalists. Roadside mechanic it is!

It can be more than what meets eye. Whatever your road side mechanic can do, the workshop folks can definitely do, especially if it's a trivial stuff as minor adjustment. I will recomment against doing that, unless you are sure about this roadside mechanic. Just a thought!

I too voice the same opinion of RX135.

Go to a fuel-injection pump service specialist...they may be able to solve your problem....

A guy I know (and trust!) has fitted a MICO pump(will get you specifics if you want) to the Indica diesel as opposed to the Lucas-TVS one...He says the bottom-end is much better and the car doesn't stumble when the AC is switched on below 1500 RPM....Fuel cons. increases by 1-2 km/l which is negligible.....

wow, can you tell me the details? Which pump is it and where's this guy? How much did it cost? At Around 80-90K kms the fuel pump overhaul comes up which will cost 7K. So i may as well get a new fuel pump then!

gr8guzzler · 14th August 2005, 02:07

He knows its lean...and he's asking for how to make it rich.....

TSK no idea.....guess guys like Pshyco or Dom can respond better

Cheers!!!

Well I'm just sharing my $0.02, that's it. If Psycho or Dom can pitch in with other useful info, its just as well for TSK.

TSK, about the Pump: Its a MICO distributor-type rotary pump from the Tata Sumo, or Peugeot (Jeep). There are some minor differences between these two pumps but once you fit it , it doesnt matter, you HAVE to calibrate it to the Indica engine. Only an adapter plate needs to be made as the mounts are different. My friend who runs a garage in Mysore has done this to a couple of vehicles and the customers couldnt be happier...
