Chips Can they be detected by Main dealers After Removal?

[sdm197]

Hi All,

The fuel economy aspect of chips attracts me but I do not want to invalidate my warranty. The Chrysler alternative is £1500 which is very heavy on price I feel.

My question is if any of you are using chips do you remove them when going in for a service, and if you do can they be detected that they have been on the car in any way?

If you would feel more comfortable, please PM me with your answers,

All replies welcome,

Steve.

After watching (& doing myself !) a chip replacement in my mates CRD, I can tell you that taking a Chip on/off leaves no trace whatsover.

BUT, if you were to do it repeatedly, then I imagine that some of the heat proof foam/ sound deadening insulation on the cylinder head (which needs to be gently bent back to access the common rail) may show some 'evidence' after a while - but that would be after many, many goes !

Yes they can.

Could you please explain this a little bit ???

its easier to show than explain !!!!!!

basically, once the plastic cover has come off, you need to gently lift the foamy sound proofing slightly to access the Common Rail connector (& to save your burning your fingers !), its a VERY easy job, but if it was done repeatedly, would show 'evidence' of use.

Just to clarify this further for our overseas friends, we're talking about the CRD diesel model here and the most common form of chipping is a black box of electronics that plugs in between the wiring loom for the injector rail and and the physical injector rail itself. It delivers more fuel to the engine in line with specific parameters for each model.

As this is a plug in unit which theoretically doesn't interfere with the main ECU itself, once removed is undetectable.

The sound insulation on my particular CRD is very easy to remove/replace and as MTC says would take a lot of removal sessions before any wear was detected!

Thanks for the clarification Stefan, once I read the earlier post I made the connection

Hi Guys,

Thanks for the replies so far, one little thing I did think about is would pulling fuse 11 have any benefit to those running with chips?

Again if you dont want to disclose using a chip PM me I am curious,

All replies welcome,

Hi Steve

my mate tells me that it has exactly the same effect as on a non-chipped car i.e much more aggressive gear changes (until the gearbox memory starts slowing them down again !)

Hi Steve,

I do the periodic fuse 11 jobbie and also the ignition II, wait for all lights to go out, slowly depress throttle all the way down and slowly back up, then ignition off and then start, that apparently does something to the throttle position too, I have noticed a difference when doing that on mine.
