Not trying to push anything here but adding LENGTH to the max Injection Pulse Width is NOT as the manufacturer intended tracks. That's why you can only achieve around 20% power increase with injector style chips. Its putting in diesel when the piston is heading down and its too late to inject more fuel. hence the black smoke when you try to go past 20% power.

Variation of fuel rail pressures is part of the designed of a common rail system and thus you can get 50% more torque without blowing smoke. The injection start and finish times are where the manufacturer intended BUT more fuel is delivered during the opening time with Rail Pressure tuning.

We use/sell both types so have a fair bit of experience here. We also have a module that incorporates both styles in one unit for power hungry folk.

Re: Anyone tuned a CRD yet?

Just to be absolutely clear. Racechip does not alter injection parameters.

Funny also that SB chip says in their blurb that they dont change timing. In fact, if they DID change the timing they would get MUCH MORE POWER from the engine. Increasing the start time (or advancing the timing of INITIAL injections is where you get heaps of power. However, this is a very very hard feat to accomplish wby just grabbing the injection signal. To try to premept the signal is too hard, so what we do is alter the crank angle signal to fib to the OEM ECU that we are at x degrees BTDC when we at at y. So we say we are at 15 deg but in fact we are at 17. So we are advancing the injection point by 2 degrees. Just 2 deg gives a whole lot of torque.

This applies to Fuel Pressure tuning as well as Injector PWM tuning. (ie Injector Chips)

While the racechip does increase pressure by a max of 0.2 bar, it also adjusts various injector parameters, not just boost rail pressure:

How does the RaceChip work?
The RaceChip is connected between the engine control unit and the injection unit. The engine control unit normally sends the data directly to the injection unit. Now, the RaceChip receives the data first and optimizes it tailored to the driving situation.

Furthermore, the RaceChip is only active, when you need the performance. Thus your driving is engine-protective. We modify the injection values of the vehicle with the RaceChip, i.e. the injection quantity, injection duration and the injection time are optimized. Additionally, the charging pressure is increased by max. 0.2 bars.

This optimization results in a power improvement respectively leads to a fuel saving.

I don't know whether the Steinbauer is better than the racechip or not. I do know that I wouldn't be coughing up a few grand to find out. I'm pretty happy with the racechip's performance and price point.

Re: Anyone tuned a CRD yet?

Hey Chip Tuning, This is an open forum, the owner Scott does not mind companies telling us about their products. Please feel free to tell us what you can or will be able to offer.

With the current options we have, we are limited by the piggy back style, so there are limitations to what you can trick the ECU into doing. Until they break the encryption of the ECU, we will be limited in our choices.
Having been involved with the XR6 Turbo scene, I have seen piggybacks come and go with limited success. Being able to crack the ECU will lead to massive tuning options and increases that will blow your mind.

As for the Catchcan discussion, the reason car makers do not fit them is because it requires people to empty them. If you do not, they will release oil and that is not a good thing.
I also do not see the need for a CC unless you plan to up the boost, of keep the car for a long while. Quality oil and fuel will reduce the problem.

Re: Anyone tuned a CRD yet?

Hi Enforcer

Thanks for that.

Yes the Piggy Back option is the easy first steps. We just needed to provide the OEM plugs to both the Fuel Rail and MAP sensors.

Going in through the EOM programming is another ball of wax. I can edit the program via the factory ECU once I have it out of the car but getting the ECU out is something people may find less appealing. The benefits of reflashing are stealth and ability to turn off the EGR and on car equipped with DPF we can turn that off too.

The piggy back option is not in saying that. The performance gain is very good in fact. About 30% more torque

I do a forum discount on a few forums for other vehicles so if the forum admins don't mind I could offer this here as well.

RRP is normally $999 or $1299 for EGT Controlled Module

With the forum discount from our Sydney store the price is $899.00 and the EGT Controlled Module is $1199.00.

EGT (Exhaust Gas Temp) Control is where we safeguard the engine as if the engine gets too hot the Module automatically dumps the performance tune in favour of the factory tune until temps stabilise. (This can occur when towing heavy vans/boats up hills etc and with ANY Chip/Module on the market)

When the temps stabilise (ie top the hill and reduce throttle) the performance tune is re-established automatically. The EGT Controller also has a LED display that sits inside the cabin and being a digital gauge, it is super responsive and accurate.

If one does not tow over say 1.5 ton then no need for the extra EGT Controller. HOWEVER, this form of engine protection is very cheap insurance, and is still cheaper than the competitor’s products that are around $1400. The EGT Controller is highly recommended and a must in our opinion if you do any form of towing of caravans or ski boats etc.

The Module is very easy to remove though you do not need to remove the EGT Controller/Gauge. The Dealer will not have a problem with the EGT Gauge since you are only measuring temps. This item just plays in t the Performance Module.

$25.00 gets it out to you usually next day. All step by step instructions come with the kit so you can fit yourself.

Flash Tuning is $899.

Re: Anyone tuned a CRD yet?

Regarding Oil Catch Cans. It is actually not dependant on boost level. It is a problem because of blow by and this oil vapour then mixing with EGR and cooking / baking onto the inlet tract. The earlier you catch this the better but it doesn't take long to gunk up as seen in the pics posted previously.

As a testament to this, these pics you see above are from STANDARD VEHICLES !!!

Re: Anyone tuned a CRD yet?

Something else I recommend ... have used many but we don't sell them ... is FilterMags

You simply place the strong magnets onto the outside of the oil filter housing. The ultra strong magnetic force starts to pull metal particles from the bearings, rings and piston bore against the inside walls of your oil filter. Check out these vids

Demo with clear bottle

Re: Anyone tuned a CRD yet?

Oi Oi, first post after reading this whole thread.
Re catch cans, cast your mind back to the old cars of yesteryear that had a breather tube which dumped the residue right on to the road!

The catch can is the next best thing IMHO.

Great information here, thanks.

I am shortly retiring and looking for a tow vehicle, the Jeep ticks all the box's for me.

thanks again,
sean

Anybody know what size the canister is? This product seems good, and I cant see any downside.

The only problem with the magnet is the WK2 has a plastic filter housing

Re: Anyone tuned a CRD yet?

Nice idea with the magnets. The same concept as the magnet in the bottom of a transmission pan.

An alternative is a magnetic sump plug.

however, the oil passing over the magnet on the filter is much more and all oil needs to pass this at some time. The magnetic sump plug has limited flow around it AND is no where near as powerful
