Yes it is different - each gear has a different RPM limit.

Speak for yourself - mine does a genuine 160+. Like I said, dont ask me how

You guys slipstream your safari to reach 160kmph

ECU-remap

, I don't dare touching that until I finish the Warranty period!

The other option left to me to beat you (for the max speed) is to drive my machine to a hilltop and drive down in 143KMPH then shift to neutral

. I will get this type of geography a lot at my place!

ECU-remap ??? for Safari.. Havent heard of it as of now. (all stock)

No slip-stream either (it would be like cheating D)..See a straight wide open strech ...steadily gather pace till 140 (expressway) and then take it across to MAX

Fine Rahul, All these days I was believing that we can get the ECU remap done 'even' for Safari! Is there anything limiting us doing so (other than warranty!). In worst cases we can get the band raised for rev limiter for 5th gear. I think its not as simple as I thought after reading a post from viper regarding the remaps. (Couldn't search and find the post now)

If I understand you correctly- just reach the magic number 140 'steadily' then go further (yes on an expressway). But again the rev-limiter will block the fuel injection once the engine RPM reaches the limit isn't so? I may be wrong and may be there is some technics that you know but not me! Did I furnish my doubt clearly?

Well, it doesn't. I've briefly taken mine to what the speedo showed as in excess of 150 but a little below 160 once on a stretch between Rajpura & Zirakpur, didn't get enough road to test beyond that. Definitely need Expressway conditions & good ones at that where no vehicles on the wrong side coming towards you or bikers or cyclists or tractors - what an endless wishlist

A piece of advise, dont do this in your runin period.
If I were you, then Id try these stuff well past first service. Get to know the road which is appropiate for these serious speeds. More importantly you need to get familiar with the handlings dynamics of this 2+tonner. It took me 3-4 months to get used to the lenght and width dynamicsof my safari..

I always thought that ECU was coded to block serious speeds & RPM limit until 5-6k If i am wrong

Thanks

I have done 7000+ Kms in 5 months! First service is done at 5200Kms at the dealer place itself. I used to drive Tata 407 for during first job (to transport Base stations for Mobile communication-Though I was an engineer by designation at that time!) But I completely agree with you that there is nothing other than time that can make a driver better handler of any vehicle. Thanks for your suggestions and support- I love to talk to all who love the machines!

Thanks Suman, happy that I am getting good suggestions from seniors. I think I will get good stretches on my way and can try this!

TBHP and the folks here really rocks.

Yes, do that but (as pointed out already), NOT TILL YOUR ENGINE IS RUN IN. For the first 1,500 kms, do not exceed 100kmph

suman my man!binoy's mentioned he's clocked over 7000 kays.
diagnosis:you are over-worked.
prescription:extra bacardi for you tomorrow.....cheers:

you are dead right! I think I need to start on the Bacardi NOW

Is there any rattling on the safari. A tata guy told me that it is the only problem with the vehicle.

Steeroid · 11th August 2007, 00:34

Gents

When you see the speeds 'climbing' from 140 to over 150 like you've mentioned, please check your tacho - it doesnt move...what you're talking about is possible on a gentle downward slope (not perceptible) and you will notice that the RPM is STUCK at about 2,300.

Therefore the engine is really not going faster.

I wasnt talking about this 'method'.

Agreed. I have heard of people claiming to have crossed 165! but have come back saying rpm needle was struck to 2300rpm.

Fact is the stock engine management system for Dicor prohibits anything over 2300rpm due to various reasons.
