ROVER 75 Tuning

LANDROVER FREELANDER TD4 2L 2000-2007 PLUG - IN DIESEL CHIP

SYNERGY® 2 TUNING MODULE & NEW MAF SENSOR

"Freelander td4 transformed"  says one of our many TD4 customers this week Also available for Rover 75 & MG ZT.


The BMW engine in these vehicles is very susceptible to a weak maf sensor signal causing loss of torque below 2000rpm. The symptoms are very slow throttle response, heart stopping delay when pulling onto roundabouts and out of junctions, autos often stall when moving off and manual cars need a lot of gearchanges to keep the rpm above about 2000rpm, especially on inclines. Towing is horrendous and in some cases there are flat spots, hesitation when you open the throttle, clouds of smoke and appalling mpg.

You could of course just replace the maf sensor but the Bosch maf sensor is expensive ~£200 and not very reliable and clones and cheap Bosch alternatives do not usually work properly nor for long. We've tried them and have lots of feedback from others who have and had to get their money back. Also watch out for counterfeit Bosch mafs, you can tell them by the suspiciously low price. Checkout Bosch's website if you think we are making this up!

12 years ago we launched the Synergy 2a (aka Ronbox 2a) which uses a low power state of the art microcontroller to boost overall performance and also to compensate for maf sensor deterioration and allow a low cost, more reliable maf to be used to ensure optimum performance from below 1500rpm.

For little more than the cost of a new Bosch maf, our Special Offer comprises our 2a dual channel tuning module PLUS a brand new Pierburgh maf sensor, PLUS the special 5sided Torx bit for maf removal PLUS a long reach Allen (hex) key for air filter cover removal. Please note that the maf sensor we supply does not work as a direct replacement, it needs the Synergy 2a.

  • MUCH BETTER PERFORMANCE FROM BELOW 1500 TO 4000RPM
  • REDUCED TURBO LAG & ENHANCED THROTTLE RESPONSE.
  • IMPROVED FUEL ECONOMY.
  • EASY DIY FIT USING 100% OEM CONNECTORS.

Specs:

  • Upto 150bhp at 4000rpm on our Rover 75 cdt, 165 on a customers cdti, 148.5bhp on a TD4.^

  • 45% increase in power and torque at 1750rpm on our 75cdt^

  • 24% increase at 3000 and 37% at 3600rpm on our 75^

  • 5 power settings and 2 maf compensator ranges. Low for weak Bosch maf,  medium for our Pierburgh maf.

  • Fuel consumption 10-15% better*

  • Transferable when you change to a different vehicle for £29.95 (new cables & reprogramming)

  • 5YR WARRANTY (Synergy MODULE ONLY, MAF IS 12MONTHS)

The Pierburgh maf we supply is an oem Mercedes part and was chosen for its excellent value. It cannot be used without the Synergy 2 because it is calibrated for the Merc 2.2L engine not the BMW 2L M74n.

You can tell if your existing maf signal is weak by simply unplugging it and going for a drive. You will notice as soon as you let the clutch out!

However you cannot use the car without a maf because the performance will be below par and the fuel consumption will increase, it will also struggle to pass the MOT smoke test and may even be failed if the tester notices that its been unplugged. So the answer is our Special Offer - its the best £240 you will have spent on your 75, ZT or Td4. (TD4 2L models only, not MK2 2.2L Peugeot engined models)

 

TD4 OWNER FEEDBACK:

MISSION STATEMENT:

We've sold thousands of our Synergy range of diy fit, single and dual channel digital tuning modules since 2005.

This means you can be sure of a well proven and reliable tuning product which will enhance your Rover, Mg or Freelander as well as restoring lost performance and mpg due to an out of spec maf sensor.

We can keep our prices very reasonable indeed, considering the results you will experience, because we design, manufacture and sell direct to customers and therefore also are best placed to provide back up should you need it.

You can see from the owner feedback above, from Ebay, our websites and recently, from our 100% 5star TRUSTPILOT customer reviews, that buyers think very highly of the Synergy and our service and support.

You may never need another tuning box because you can transfer ours to your next vehicle for £10 to £36 depending on whether it just needs reprogramming, or new cables as well. We do many such transfers every month, even on our very early Synergy modules which are still going strong.

FITTING is EASY:-

This IS straightforward and there are photos on the webpage, but in short it is simply a matter of removing the engine cover and air filter cover, disconnecting 2 plugs, fitting the Synergy connectors between the sensor and plug you've just disconnected and that's it! Total time about 30mins and anyone can do it. The module is attached to any dry surface with the heavy duty Velcro supplied eg inside the battery box on the 75/ZT or side of the fuse box on a TD4. Full instructions are supplied and we are just a phone call or email away if you have any queries.

If fitting the Pierburgh maf, then use the security bits supplied to undo the 2screws that hold the Bosch on into the housing, remove it and fit the new maf. It only fits one way so you cannot go wrong. Then make sure the Synergy 2 has both switches down and is on a setting between 6 and 10. If trying it with your existing maf, use settings 1 to 5. If your maf is 100% okay you can just leave the Synergy maf switch off for now.

HOW IT WORKS in brief - more info on the tuning-diesels.co.uk webpage.

The module has two channels, one processes the fuel rail sensor signal, digitally remapping it to accurately adjust the fuel with regard to driver demand and rpm whilst the second channel does the same for the maf sensor. Being digital, and with our proprietary mapping technology, we can alter the fuel different amounts at different parts of the rev range so as you can see from the label, you can choose where to have the performance gain and how much extra performance you want or need. The maf compensation is in two ranges - low for weak Bosch maf and medium for use with our Pierburgh maf.

Most owners will find setting 2 or 7 gives a good blend of performance and superb fuel economy and you can easily turn the knob when you need more power for towing for example. So by referring to the label, you can see that there are 2 columns labelled torq and power. Torq refers to the performance boost below about 2000rpm and power above about 2500, with some overlap in between. Thus when not towing and for superb economy on long journeys setting 2 (or 7 if the Pierburgh maf is fitted) works well, but if towing then setting 3 is better. The power mad like us, will of course always use setting 5 or 10!

WHY IS IT BETTER THAN A STANDARD TUNING BOX OR REMAP?

No matter how much you pay for a tuning box or remap, if the maf signal is not correct the performance & economy will suffer. So had you spent £300-500 on either and were disappointed with the results, then you'd have no option but to spend another £200 on a Bosch maf. Only then would the tuning box supplier or remapper take any complaint seriously. If you tried to cost cut and fit a cheap maf, you'd probably still be disappointed and have this blamed on the cheap maf.

DON'T  SPEND £500-700 TO TUNE YOUR 75/ZT WHEN OUR OFFER COSTS HALF AS MUCH & YOU CAN TRANSFER IT WHEN YOU CHANGE VEHICLE FOR £10-36.

MONEY BACK GUARANTEE AND WARRANTY full terms and condition are below and on our website.

Rather than try and seduce you with impressive figures for power and torque, it is our policy to give you 30days to evaluate the module for yourself under various 'real world' driving conditions. Dyno figures are meaningless when it comes to telling you about part throttle performance, turbo lag reduction, low down torque and in-gear acceleration since they are always obtained on full throttle in 4th gear, usually from about 2000rpm upwards, taking a few seconds.  Also, your vehicle may no longer be producing the manufacturers quoted figures so you will often not be able to achieve the claimed increase.

If you decide the module is not for you, then mail it post paid no later than 30days from the date of delivery (not from when you fitted it). We don't refund any post and packing costs and items mailed outside the 30days will be returned to you unrefunded.

After the 30days has expired you will be deemed to have purchased the module and our 5year return to base warranty will apply.

MAF SENSORS ARE NOT REFUNDABLE ONCE FITTED BUT WILL BE EXCHANGED IF FAULTY AND HAVE A 12MONTH WARRANTY [WHICH DOES NOT COVER OIL CONTAMINATION FROM CLOGGED PCV VALVE OR AFTERMARKET OIL FILTERS.]
