Chips

[Sue]

Hello fellow Defender peoples.. :p

I am looking at putting a chip in my 2011 2.4 Defender and am looking for advice as to which chips are the better to use. Does anyone have any experience with chipping a defender (good or bad) that they would like to share with me?

Thank you... Sue :)

BAS remap

[ezyrama]

Hi Sue

I found Pelican Pete's at Ashmore are pretty good :p

Seriously though, I got one from
tunerchip@gmail.com
Diesel Express Home Padge Index (http://www.tunerchip.co.uk)

Landed 2 of them for about $270 AUD. So far I have found it really good for towing and I don't use 1st much anymore. I did look at taking the car to
Davis Performance Landys
233 Annangrove Road, Annangrove NSW 2156
Ph (02) 9679 1978
Fax (02) 9679 1993
I spoke to him a while ago and he quoted me about $1k to remove my ecu, remap it and refit it. Also offered me a loaner whilst I was in Sydney but as yet I haven't got down there.
Regards Ian

Do not Chip...

Remap only... BAS being the better choice :cool:

I would be getting some EGT readings asap :cool:

If you've got the $$$,

Fit an upgrade intercooler (AliSport) first, will give you most from your remap and help keep those EGT's down.

100% for a BAS remap, I've had mine for 4 years and 50,000k's without issue.

Consider "Nuggets" replacement ducting from air box to guard, as the factory ducting leaks and is distorted and not consitant in its diameter.

Finally fit a DeCat pipe and centre muffler removal pipe.

That will give you about 450nm and 120kw with the confidence that being from BAS it's been tested and the improvements to performance is not risking the health of your motor.

Why not? :)

and thank you everyone.. we have at this stage been considering superchip bluefin.. which I believe remaps.


I'm a little confused though.. what is EGT??

Thanks.. :)

Remapping loads the entire engine fueling (and in quality versions - Timing) tables with new versions.

Mapping written by experienced tuners can get the best out of an engine without risk.

Chips on the other hand are intercept boxes - and just modify a signal sent by the ECU into another signal... Often they just dump more fuel in without adjusting other parameters.

You will often see them advertised as "completely safe" and "won't void warranty" which is far from accurate...

EGT is Exhaust Gas Temp, a product of combustion. Just fueling up a diesel will make more power, without more air it will also smoke more. And as a byproduct more heat.

Excessive fuel will raise combustion temps to dangerous levels and can melt engines....

[Tombie]

No engine with a modified fuel table should be without an EGT gauge.

[Tombie]

Superchip maps are pretty generic too. BAS provide tuning to suit use and mods...

[Drover]

EGT = Engine Gas Temperature (temp of the exhaust gas exiting the motor and then entering the turbo)

If it gets to hot it will cook the turbo, warp the head, melt pistons and cost big big $$$$$$.

The primary culprit is over fuelling, along with labouring the engine when using big throttle openings. A good indicator is black smoke.

If you just "chip", it only changes fuel injector flow rates and opening duration, basically it just tips more fuel in. So EGT's will go through the roof.

If you do a BAS remap the whole engine management programme is changed to produce extra power, not just adding more fuel.

I don't think there is an easy way to fit an EGT gauge to the TDCi either,another reason to avoid cheap performance chips. Pat

Madman EMS mount directly into the turbine exhaust (post turbo)...

Tombie,

How much impact does having the probe on the exhaust side of turbo have on temp readings ?

Is it preferable to have it between the head and turbo ?

Cheers

Turbo acts as a thermal sink, reducing 'true' temperature readings by a significant (~200c?) and varying amount making readings indicative.

Probe pre turbo gives more accurate/reliable readings.

I have a Madman with EGT (pre turbo) and drive to it.

I've read the difference between pre and post turbo readings is about 100 degrees, that is 100 degrees lost for a post turbo, the further down the dump pipe you go the more heat you lose. Also depends on how quick your gauge reacts.
Pre turbo is by far more accurate, but there's nothing wrong with post turbo, just be aware of what the numbers on the gauge equate to in terms of real world engine temp and drive accordingly :)

Yeah, but that's the issue, the loss could be 100 degrees at certain times, or 50, or 200, so you never really know how close to the edge you might be. On that basis you probably need to derate by the worst case value at any time if you want to be sure you're safe.

That said, plenty of people run post turbo gauges, but then again what are the numbers on how many turbos get cooked that way - the data is unavailable.

Either way, it's better than nothing as long as you understand the limitations - however, if you take it as read it has the potential to be worse than not having one.

n p o - did you need to take to turbo off to drill and tap the hole for sensor ?

Is there a safe option with out removing the turbo?

May be a vacuum running while drilling or a magnet ?

Would a few fine metal filling being sent through the turbo have the potential to cause harm ?

Most do it in situ - engine running is a popular option too. I had mine done during a service (needed an odd tap that I didn't have) - can't remember how they did it in the end, but they had successfully done many without issue (for what that's worth).

Can apply grease or something similar to the drill bit to catch the filings :)

Got a quote from MadMan for their EMS unit (PUMA kit).

Landed and delivered to the door, $407.00

EMS Kit monitors -

Exhaust Gas Temperature
Coolant Level
Coolant Temperature
Oil Pressure
Transfer Box Temperature
Oil Pressure Switch
Main Battery Voltage
Engine Hours

Installation seems straight forward, other than the EGT sensor.
