I just tried one number from a shop you mentioned. Speedsport. It was wrong as posted on their web site. The number they gave turned out to be a horse race betting number.

If you have a good number from them or better yet, a number in the Punjab, I sure could use your assist.

This is a nice idea. Could anyone highlight which of the wires from that sensor do i bring inside the dashboard? Or may be bringing one of them should serve the purpose. I am seriously thinking of this. 90% of my start is grade as i live in Gangtok.

Hello everyone,

I have escalated this issue with Mahindra, let's see what they will do. We are facing this issue of climbing hilly roads which is possible thru massive clutch slippage only. The vehicle has considerable drop in performance at high altitudes as well as is unable to climb the hilly roads properly.

If Mahindra is unable to solve this issue, then I will do the state of the art workaround for this issue, have already found the solution. The MAF sensor gives the proportionate voltage on the scale of 0-5V. When we disconnect the terminal, the ECU sees full 5 V which equates to high air volume density and thus rich mixture results in power boost. The workaround is to make an adaptor which sits between MAF sensor and the terminal harness and fortunately the connectors used are TYCO automotive 5-pin types which are easily available. One has to wire it in such a way using the relay, So with a flip of switch the ECU sees full 5V to give the boost and in off position the ECU will get default reading.

Today evening, a real-time test was demonstrated at Shimla under the supervision of Snow View Automobiles , a Mahindra authorised showroom and workshop. Vehicles involved were my own Thar along with other Thar CRDE provided by showroom, Bolero M2DICR, Scorpio mHawk.

Bolero and Scorpio managed to climb the selected steep road smoothly whereas the Thar only managed after considerable clutch slippage which resulted in clutch burning smell. Same test was repeated with MAF sensor wire disconnected and as anticipated the result was awesome and every one was surprised to see that the same Thar with MAF sensor wire disconnected climbed the same road effortlessly. .

The drivers were provided by Snow View Automobiles and they also confirmed that Thar lacks torque at lower rpm and hence they had to keep the vehicle either in momentum or use clutch slippage technique in order to manage the climb.


Mahindra are you listening?

The guys who changed the 2.6 engine to a 2.5 screwed up by making the engine oversquare.
Who puts an oversquare engine in an off roader? Oh I forgot its the geniuses at M&M.
One of their crap ASMs was telling me lately that why don't you put the vehicle in 4X4 LO on paved tarmac roads to get away with the situation. When I confronted him that other vehicles from Mahindra like Bolero and Scorpio manages the hill stretches well enough he said you cannot compare the THAR with those vehicles. Surely, The short stroke oversquare engine is at the play for the mess and Mahindra is at fault. Expect clutch burning and slippage on hilly terrains.

I have blanked out the EGR and have had some improvement across the powerband..
It costs just a few 100 bucks at your local mech. Its worth a try.

CRDe.
I have done a few other things but this is the simplest. Pls use good gauge metal as it gets pretty hot.
A 20k DT box is the next step.
Then perhaps a cat-con delete.
