Tigger:
The main downsides of the remapped ECU route :

You usually have to send the ECU away, so your vehicle will be off the road for a while

If you ever have problems with the vehicle, you can run into issues with getting diagnostic information from the vehicle

Warranty claims aren't much of an issue I am guessing due to the vehicle age, but that is another factor.


Plug-in solutions may not be perfect from a technical perspective, but they do have some advantages

Depends on the age of the vehicle, flash type (2002 onwards ish) can be done straight away.  Earlier types require the ECU to be socketed.  Anywhere decent will have slave ECU's.... so can do a straight swap.  (I know Allisport do)

Edited to say:
You may have meant this slightly differently...

A interupter box could be sent through the post,  but an ECU needs recoding to the alarm unit (injector codes aren't as important), so not a straight swap you could do at home... means visting the 'supplier' - but only takes 10 mins when your there.

Why's that??  All the chip/relfash does is alter the fuel map... and at times plays around with throttle progression.  Getting Info stored in the ECU is no different from a standard vehicle.

True... hence why you'd go to a reputable place... so in theory nothing will go wrong because of the new 'tune'

They also add fuel at the wrong time, thus messing up the timing and thus can cause more damage/wear and tear.

All the boxes do is confuse the signal, and allow the injector to inject fuel for longer.... but not at the right time.

Some of them will also cause the engine warning light to come on at times, and even make the engine revert to limp home mode.


With a good tune, a bigger intercooler and with the boost up a little bit (17psi is good  :wink: - though most of the interupter boxes don't like it when you do this... well the ECU doesn't - it gets too confused) you'll have quite acceptable performance.

If you mess with the ECU then you'll need a rolling road as you have done a few miles.

Not really, although all remaps/ecu work SHOULD be done on a rolling road 99.9% are not, proving its not essential.

Its an ideal world where they are all done like that and i dont even know of a landy tuning company that has a rolling road!!
