Review: Pete's box for the 2.6 CRDE Scorpio
The 2.6 Scorpio CRDE is a pleasure to drive. The turbo kicks in at an early 1300 to 1400 rpm, virtually eliminating any kind of lag which is normally associated with most turbo charged vehicles. Although the engine is dated (Pushrod technology), the folks at Mahindra have done a good job with respect to refinement and relaiability. The engine revs smoothly without any hesitation. On the contrary it seems to be in a hurry to get to max revs. The torque available is more than adequate (so I thought), be it on the highway or on the hills.
Yeh Dil Maangey More
However being perfomance enthusiasts theres always that little more that we crave for. Adding a boost controller to increase the boost did cross my mind several times, but I was not sure if the ecu would cope and compensate for the additonal amount of air. I use the Scorpio on a daily basis and I cannot compromise on reliability. I decided to wait until a reliable solution was available.
A ray of Hope
When Pete's Perfomance introduced Digitial Tuning Boxes for diesel vehicles in India, I called Peter to ask if they had anything for the Scorpio. Unfortunately they did not, but Peter promised to keep me updated on any further developments. As promised Peter called and informed me that a team from PSI Technologies, the inventors of the magic BLUE BOX (I wonder what it is with the colour blue, first Viagra, now tuning box !!!), were in India to carry out tests on the Scorpio. A few days later, I was informed that Pete's Performance had officially launched a tuning box for the Scorpio. I decided to wait it out for a little more time before taking the plunge. As I have mentioned before, reliability was of prime importance. However, just like all the other Products Pete's Performance markets, they seemed to have done their homework well. People who had installed the tuning box in their Scorpio's only had good things to say. It was time to make the phone call.
The Magic Blue Box arrives
I was IMPRESSED.
A lot of care has taken overall.
Packaging is of excellent quality. The instruction booklet has clear and precise instructions on installation procedures and the Do's and Dont's. The photgraphic illustration on installation procedure is an added bonus and eliminates any possibility of installing the box in a way it's not meant to be.
The box itself is made of high quality plastic and is supplied with a wiring loom specific to the vehicle in which the box is to be installed. A nice high quality Pete's decal is also included in the box.
Installation takes about 10 minutes, most of which is spent removing and refitting the engine cover. There are 3 connectors on the wiring loom. The main connecotr goes into the tuning box. The connector on the fuel rail is diconnected and attached to the second connector on the loom and the third connector is attached to the fuel rail in place of the original connector. I used a couple of Tie ups to secure the tuning box to the metal braket which holds the fuse carrier in the engine bay. The heat in the engine bay will not affect the working of the tuning box. However care must be taken to isolate the box from water while washing the engine bay.
I did not use any fancy gizzmos and gadgetery to determine perfomance. A simple stopwatch was used. There is always more margin for error if testing is done with standing starts. The way the clutch is released, and the amount the accelerator is depressed will always vary from run to run. Therefore I decided on testing with a rolling start instead. The method was fairly simple. The vehicle would be slotted into first gear with the speed held at 20 kmph. The stop watch would be started. Gears would be shifted up at the 3000 rpm mark from 1st to 4th. The watch would be stopped when the vehicle reached 100 kmph on 4th gear.
I chose to shift up at 3000 rpm, because this is the most useable rpm in city driving conditions. I have not tested the vehicle on the highway as yet.
An isolated road with a good surface devoid of any other vehicles, human beings and animals (hard to come by, but we found one, never the less) was identified for the test runs.
Note: - Throttle postion for every gear at 100% i.e. pedal to the metal.
Without the Box - 3 runs - 16.4, 16.3, 16.5 - Average - 16.4 seconds
With the Box - 3 runs - 13.4, 13.2, 13.3 Seconds - Average - 13.3 seconds
Thats more than 3 seconds knocked off - I was freaking out - Unbeleiveable but true.
Conclusion - Go baby Go
The box is worth every cent. Like I mentioned earlier, the jeep is fast as it is, but trust me, the Pete's box gives it that extra punch, and the additonal power and torque is fantastic. You will find yourself down shifting much less often, as the new power is on tap and instantaneous. Even while crusing, when you squeeze the accelerator either to overtake or increase your speed, theres absolutely no hesitation or laziness - Simply awesome.
Theres no overheating or any other negetive effect. If decently driven the jeep will return the same milage if not more (on account of lesser down shifting). I would however recomend using a better engine oil. The oil which the Mahindra service centres use is worse than human faeces (to avoid being infracted I have used language as per board rules, but I hope everyone gets the message)
I am not sure if installation of the box voids the warranty. I haven't bothered to check with the dealership and I don't intend to. I will remove it when the jeep goes for service and re install when it's back.
The box retails for Rs.28,000 inclusive of taxes (printed on the box). Get one today if you have the money, start saving up if you don't.
Please drive safely within the required speed as prescribed under the law.

Good Review ...
Please update the FE figures as well. Did you think about replacing air filters as well?
PS: I have the tuning box on my Octavia which I fitted recently ... The overall FE has really not changed, but the FE on 1st & 2nd gear driving has changed. I have also replaced my air filters with Green Cotton.

@ Maggie - Nope, not as far as I know, but Pete can clarify that better than I can.
@ Ardy - I haven't tested for fuel efficiency. I was travelling and returned only on the weekend. Will test and update. The filter has not been changed. The stock filter is a foam one and I am sticking with it for the moment. Warranty becomes void in the Scorpio if the air filter element is changed - Go figure.
@ J.k. - I am sure it will, but read as above.

Great review, objective and exciting. Will wait for more inputs from your experience before I'd take a plunge.
Thanks for sharing,
(Just talked to Ms.Bina @ Pete's, cochin; they are arranging for someone to brief me tomorrow morning @ Ahmedabad on the box; told me its a truly plug & play thing )

Btw from what I have heard the actual effect take some time to show up, did you get these figures immediately after installing the box?

A very good review Sideways!
How much has your vehicle run till date (odo reading in total)? Is there different tune/map for Scorp, if so which one are you running?
Last but not the least some info regarding the better oil would be helpful, what is the rating and spec?
