IDI diesel tuning for rarified freezing air Hi,
We will be heading to the hills on our Tata indica DLS.
The temperatures are going to be below zero with snow and rarefied air. My concerns are two.
1. At low air pressure, indica does "missing". I am told that fuel pump tuning for lower air and high fuel ratio is the solution. Where can I get it done in delhi. The Tata workshop guys are clueless as always. On old 800s I could do this by moving a screw. Is there such a screw in the indica. If so, where is this screw. I will adjust it. Any pointers. Or any workshop in Noida/Delhi which has a good tuner who can adjust the FP?
2. Sub zero temperatures mean that morning starts are a pain. I will be using diesel with anti freeze(Available in the hills). Apart from that I plan to pour boiling water on the engine block before starting. This is one of the things what truckers use. Since I am going in the mini truck, this should suffise, or it wont. Some truckers light fires under their fuel tanks which I definitely wont even attempt.
I am not too worried about coolant freezing as instead of water I will be using antifreeze coolant liquid.
I know ideally I should be taking a turbocharged car to compensate for lack in pressure, but I guess loss of power is not going to be too much of an issue at around 2700mts. I had gone to such heights in summers and apart from "missing" there was no issue. Moreover this time I have a "natural" cold(freezing) air intake for additional power .
So guys please put in your suggestions. A good mechanic who knows how to tune FPs will be great help. Otherwise any pointers to adjust this myself will help. Could not find any workshop manuals for indica 2002. I am not very technical in adjusting stuff and the most I have done is removing glow plugs. But I think adjusting some screw is not going to be more difficult. |
