hey guys after resisting the urge for quite some time now i gave up and finally decided to go for an aftermarket air filter and tuning box for my car


sent a query to petes a month back and was advised the green filter universal storm with fitting and dynamisation kit and petes box for magnum.
at the same time i came across a thread on team bhp on race dynamics bangalore and on inquiry came to know that they are working on a piggyback ecu for magnum which will be ready soon below are the details of the rd ecu

XM400

a. Four switchable maps, pre-set to.
b. Stock - Works like original map.
c. Economy - Enhanced economy mode, can deliver upto 20 % more economy.
d. Performance 1 - Increase power and torque by upto 10%.
e. Performance 2 - Increase power and torque by upto 25%.

25% means my magnum bhp should go up from 120 to 150

versus

all i know about petes box for magnum is bhp goes up from 120 to 140


i have already ordered the green filter universal storm with fitting and dynamisation kit from petes and will receive it tomorrow

i would like some expert opinion and advice on which mod to go for.
the race dynamics piggyback ecu or petes box for my magnum

thanks in advance for the helpful opinions and below is a pic of my fair lady

Pretty sure you'll lose your warranty with an aftermarket ECU, versus the Pete's box which can be removed and nobody would be wiser.

the rd ecu is a piggy back ecu. installation looks to be the same like petes box with snap on connectors so installation and removal will be just like petes box
also my warranty will end in 2 months time

remapping or adding petes to magnum? that is some serious power addition to the car.

As long as the maximum boost pressures are not meddled with; using either of the piggy back ECU's should not be a problem. Make sure the maximum boost pressures from the turbo remains exactly the same as stock. You would have to use the best synthetic oil available thenceforth as long as you are using increased fueling and varying the number of injections. Both of them claim not to meddle with max boost pressures but in the real world I am not so sure.

Your best/safe bet would be to have a flatter torque curve with the max boost pressures remaining the same and the peak torque and bhp figures being same as stock.
Your attempt should be to arrive at peak torque and bhp figures earlier than stock but maintain these figures right through out the rev range. Easier said than done but this is what you should aim for. If any of the piggybacks increase the turbo boost do not touch it with a barge pole.
In the long run it would be far far cheaper for you to put in a bigger turbo( the VGT unit of the Captiva) after strengthening other mechanicals which would give you 150 reliable horses.

Got to test a swift -D with the RACE dynamics XM400 pretty extensively - Around 700km of highway driving + 80 km of city driving + 45 plus laps during the trackday at the MMST.

Economy Mode: Used this during the entire drive to the track that is about 300+ km speeds varied from 80 -130 kmph.Feels exactly the same as a stock swift,acceleration is the same,boost comes in at the same rpm as stock.Overall didn't feel any lack of performance.Hit 160 too on this mode!

Performance 1 : Used this a couple of times on the highway for overtaking bigger cars.I could feel the difference as soon as I flicked the switch from economy to P1.

Performance 2 : Used this quite a bit on the way back,mostly at the toll booths where Doomsday would take off in the SX4 and I not wanting to be left behind(Unlike memo in the gypsy) would follow suit.And boy did it help!

Drove with P2 on all the laps on the track,Boost did come in a wee bit earlier but the biggest difference was that boost would hold till about 5100 rpm(Stock swift-d dies out at around 4300rpm)

Like to add - No black smoke!

Also loved the small knob used to change modes near the gear lever.Install was done in about the same time i took to swap four wheels on my baleno ..

Overall fantastic product,Go ahead and pick it right up.the petes box is a great box too but the racedynamics box provides a LOT more bang for the buck and flexibility.

Cheers,hope this helps.

What is the cost difference between PSI Box (Petes) and RD Box?

The RD retails for Rs 26,500/- if I'm not mistaken. No clue about the Petes , it's around the same price.

RD says Rs 22,000/- for piggyback ecu for magnum
petes say Rs 28,000/- for box for magnum

also binz know anyone whos been using the xm400 longterm

[rageraver]

I am with Binz on this one.
RD is the best bet.
I had talks with both of them for my Swift DDIS too.

Petes promised 15 bhp increase and .5 mileage increase but only if box is installed with a green cotton filter or a Wind Kit.

Where as Mr.Reddy from RD has promised the gains without any aftermarket parts.

Another good thing about RD is they come to you place and install it so that you dont have to go all the way to their garage.

I am mistaken then,though i distinctly remember Sanjay saying 26.5.
Anyway,no idea about anyone using it long term being a relatively new thing. Wait till people notice this thread and you should get some long term reviews.

Have seen and driven the RD ecu'd Swift, I would strongly recommend it. That diesel swift didn't behave like a swift anymore. It left me very impressed!!

Not to mention I am currently using one for my Vtec!!

how long have you been using it and any difference in fe
what about the power- bhp difference with the rd ecu
