ROVER 75 Tuning

RANGE ROVER TD6 PLUG - IN DIESEL CHIP

SYNERGY® 2 TUNING MODULE WITH MAF COMPENSATOR

 FEEDBACK  "Money well spent! HIGHLY RECOMMENDED"


Is this your vehicle?
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. Overtaking needs a good run to build up speed.

Over 10years ago, we decided to address these woes and also give a much needed boost in performance and the result was the very successful & highly praised Synergy 2a. The TD4 shares its engine with the Rover 75 & MG ZT so these too suffer from the same annoying defects. (the TD4 has a vnt turbo otherwise they are identical)

It 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 so you can expect:

  • MUCH BETTER PERFORMANCE from 1500 to 4000rpm
  • REDUCED TURBO LAG & ENHANCED THROTTLE RESPONSE
  • IMPROVED FUEL ECONOMY.
  • EASY DIY PLUG IN FITTING - NO WIRING MODS NEEDED.

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*

  • Works with weak Bosch mafs if they are not too far out of spec nor faulty.

  • Recalibrates our Mercedes Pierburgh or Hella maf for 100% 75/ZT/TD4 compatibility.

  • Transferable when you change to a different vehicle for £34.95 (new cables & reprogramming)

  • 5yr guarantee

The full details are available on our website.

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.

 

PLEASE NOTE. YOUR MAF MUST BE WORKING AND JUST OUT OF SPEC SO THE PERFORMANCE IS BELOW NORMAL.

THIS ITEM DOES NOT REPLACE YOUR MAF AND YOU MAY STILL NEED TO FIT OUR PIERBURGH MAF IF YOU WANT THE BEST POSSIBLE MPG AND PERFORMANCE.


IF YOUR CAR WON'T RUN AT ALL WITH THE MAF CONNECTED, THIS ITEM CANNOT CURE A DEAD MAF AND YOU NEED TO BUY THE SYNERGY 2 + MAF - SEE OUR ebay  SHOP.


PLEASE ALSO SEE OUR OTHER LISTINGS FOR THE SYNERGY 2 WITH MAF SENSOR.


IF YOU HAVE ANY ISSUES PLEASE SEND US A MESSAGE. RETURNS FOR CLAIMS OF A FAULTY OR DEFECTIVE ITEM ARE NOT AUTHORISED UNTIL YOU HAVE CONTACTED US. (after 17yrs, we don't sell products that don't do as we claims and 100% are tested during assembly)


TD4 OWNER FEEDBACK:

Fitted the box to my freelander 1 today. Was like I had put a different engine in. Smoother to drive.

"Finally got round to fitting the synergy 2 box on my freelander td4.After quick call to Ron , fitted the box - what a fantastic difference in all ranges and driveability - even sorted out a misfire it had ,really good investment good product,and friendly advice ."



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 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 trying it with your existing maf, use settings 0 to 4. If your maf is 100% okay you can just leave the Synergy maf switch off for now but often the results are better with it on, even with a new maf. (especially with clone/unbranded mafs)

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

The module has two channels, one processes the fuel rail sensor signal, digitally altering 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 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 optional Pierburgh maf.

Most owners will find setting 1 or 6 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 1 (or 6 if the Pierburgh maf is fitted) works well, but if towing then setting 2 is better. The power mad like us, will of course always use setting 5 or 10!

NO NEED TO SPEND £500-700 TO IMPROVE YOUR CAR'S PERFORMANCE

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.

ORDERING INFO: If you have any queries please do not hesitate to contact is via Ebay

This listing is for a brand new, Synergy® 2 channel tuning module, for the Range Rover TD6 with the 6cylinder BMW engine.

SHIPPING INFO: Orders are shipped usually within 48hours

^No specific claims or guarantees of power or torque increase are made as the results depend upon the make & model of vehicle and engine condition. * No specific economy improvements are claimed since there are too many factors outside our control such as vehicle condition, how and where you drive etc.
