Hi Lep
Thanks for that. Just an add on to that.
If people cannot drill and tap the hole in the exhaust dump pipe feel free to take it to an exhaust place or mechanic. An air drill is small and is able to get into tight places so they will find it easier to do of course.
I know one of the dealers places the probe nearer to the cat for ease of access. This is fine because we set the top temp limit 10% higher than what stock temps read. So you can place the probe anywhere.... just take the fuse out of the chip and go find a big long hill and give it heaps.... with a load would be best ... to see what standard temps get up to. Then just add 10% to that figure for safe level of increase.
The dealer wont mind the EGT LED display as its just measuring EGTs. However we always suggest the 5 min removal of the Chip so the dealer doesn't point the bone.
On our Chips we are the only ones able to REMOVE fuel from the fuel map(not just add it like other chips). This means that on vehicles (like the Nissan 2.5 litr) that tend to blow smoke, we can adjust THAT PART of the fuel map to take out fuel. This means we can actually stop the smoke.
We do this on all Navara autos as a matter of course since the DPF delete is an option and the factory ECU no longer needs the extra fuel squirt on initial throttle roll on to heat up the start warming up the DPF.
This also will save some fuel costs.
At the same time, when we start adding fuel to make power we are also adding air (via extar turbo boost) which means we dont need to have the vehicle blow smoke to make power.
Other Chips only adding fuel via the common rail dont have the added advantage of adding extra air so in that case they will tend to blow more smoke simply because they run out of air and are now too rich for efficient combustion.
Hope this helps
Cheers
I can help you out with some those questions,
The EGT controller is located in the cabin, with the thermocouple and chipit connecting wires coming through the firewall. You need to drill and tap a 1/4 NPT thread into the turbo dump pipe, this isn't easy if you don't have the tools or know how.
The chip is simple plug and play, takes 10 mins or so to fit, and a few hours of having fun playing with different tunes.
Yes Nissan will see the EGT controller, and chip unless you remove it before each service.
There has being alot of people complaining about the YD25 blowing black smoke, I personally haven't seen a D22 or D40 blow what I would consider excessive smoke. Adding a chip is more likely to increase the smoke due to the extra fuel being injected.
