I have a 2008 3.0 D4D and looking for a little more power. I've read good things about Unichip but they are not available in my country, Costa Rica. Anyone have any insight on RaceChip? Pros, cons?

Welcome aboard, Will! :thumbup:

Not too clued up on the chips, but I'm sure someone here will be able to help. :winkx:

From what I have seen the Racechip is quite popular. There are a number of threads on the forum that you can search and also a poll on them. I think it is under the sub forum "modifications"

Thanks for the welcome. I'm waiting for 'that guy' to advise. Every forum has one or two members that knows all. I'm new here but you guys know who he is. Send him my way please.

Standard forum etiquette is to do your searches and homework first and then to pose questions. There are lots of very knowledgeable guys on the forum. No-one likes to be taken advantage of though.

Thanks Mars. I did and there is not a lot of info here. A few guys use it, one guy says it's junk and will burn holes in the pistons. So far I haven't found any valuable info like WHY it is good or bad. Maybe people don't know and I'm in the wrong place. They seem to just bolt things on that they see other people bolting on without asking themselves why that product.

Thought forums were for sharing info. Didn't realize that was 'taking advantage'

The reason why performance chips work is that it is possible to take over the injection timing and the volume of diesel injected into the engine from the engine ECU using an external processor. It is very easy to improve performance in a diesel engine. You simply inject more diesel. The problem/risk is that with a diesel engine a richer combustion mixture leads to higher combustion temperatures.

The success of adding a chip is therefore dependent on how it is implemented. The safest option is to have a chip installed that is calibrated to your specific vehicle on a dynamometer by professional installers. In that manner they can adjust the injection profile to achieve an optimum setting for your vehicle which will not be the maximum performance you can get from the vehicle.

With the "plug-and-play chips" you hope that the program on the chip is a conservative profile and not simply set up for maximum power or somewhere close to it.

Holes get burnt in pistons if there is a hot spot that is created on the piston crown due to too much diesel being concentrated in one spot. Normally this results from a leaking injector. I suppose it is possible to over fuel an injector to the point where the diesel in not atomized properly leading to a hot spot on the piston but I am speculating. I suspect that the burnt piston/s was a combination of over fueling and old/leaky injectors.

Another risk is the increased combustion temperatures lead to increased exhaust gas temperatures and increased cylinder head temperatures. Under heavy load such as towing a trailer uphill and full acceleration it is very easy for the cylinder head temperatures to quickly reach dangerous levels which could lead to valve seat recession, burning exhaust valves or other damage to the cylinder head.

Most guys go for the Dastek Q-chip which is installed and calibrated for your specific vehicle on a dyno and they follow a more conservative approach. The Diesel Torque chips also seem to be quite popular. Of the plug and play chips they seem to be the most popular.

It is not only the risk of over fueling but some guys have also reported their vehicles going into limp mode under hard acceleration or load conditions such as when overtaking another vehicle.

There seems to be a correlation between the price of the chip and the end result. I would be hesitant to fit a plug and play chip.

Mmm, now that is what I call an informed, educated, and well-worded response. Informative, based on fact, rather than speculation. Your reply also underscores my philosophy of rather keeping the vehicle stock standard. I drive a 2.5 D4D SRX...it is a donkey. I knew it when I bought it. It drives like a donkey. But it just keeps on going - the part I am interested in.

If you want more power, sell, and buy something more powerful.

Good post Mars


Just to add that if someone still feels they really "need" a chip an EGT gauge should be installed with the chip
