Guru's to comment on that.

Now,

@RDK: Can i Procure this EM400 and keep switching it between my cars?

I have 3 diesel cars!

What is the difference? Can you elaborate?

[rajathv8]

can these boxes be used with petrol engines? is it wise (& worth) to use them with a 1.1 engine?

Racedynamics has separate ECM's for petrol's. The XM's are specifically for deisel's. It's worth even for a FI 149cc bike, let alone your 1.1L engine.

A Standalone ECU replaces the existing stock ECU of the car whereas a Piggyback ECU sits alongwith the stock ECU and does magic!

In that case the EM400 is a piggyback ecu which does nothing but increase the rail pressure. It is similar to the petes box. RD has standalone ecus too but i dont think they are applicable for gen 2 crdis.

Piggy back ECUs basically take over the engine works from the stock ECU leaving it with other non essential tasks. They are usually a cheaper alternative to standalone performance ECUs.

They are easier to install and manufacture as compared to replacement ECUs.

RD does manufacture standalone ECUs.

Pete's is a piggyback too.
PS: I've lost count of the number of times you mention 'piggyback'. You enjoy the term,heh?

One question regarding this performance enhancers, (i might appear stupid), will this not put more stress / load on the engine and reduce the engine life, and moreover, the sudden surge in the power will have a considerable wear on the tyres, obviously the manufacturer is not going to test these sudden power surges on the tyre, this leaves a question to all those who put these boxes, what would be the right / proper tyre choice for these kind on mods.

No wonder, the manufacturer voids the warranty if this box is installed. The ripple of effect of the sudden power surge on the tyres, suspension and what not, will certainly have a big impact.

I may be wrong and I would like to correct myself wherever I am wrong.

You are very right. But then when you are taken over by thirst for power you really dont worry about all these things

[balajird]

I feel better now, good to know that my understanding is right . Though, now i understand that the "thirst for power", i would also like to know How do you arrive at the right set of tyres and is there any suspension setting changed?

Tire choices for high speed and handling applications are Advan & S.Drives from Yokohama, and PP2 from Michelin (tire gurus, please correct/ add-on to this).

The right tire width and dia again is based on the application and user preference- why dont you try the tire bible? (Car Bibles : The Wheel and Tyre Bible Page 1 of 2)

Hmmm! You could add Conti's CPC2. It is good.

Congrats on the car & RD unit.Pls post some pics.
Upgrade your tires ASAP.
