FOR THE ROVER 200/400/600 SDI 105BHP, FREELANDER 1 XDI 98BHP

Gives older diesels a new lease on life.       
This 2 channel digtal tuning module has been on sale for over 10 years and has been proven to work reliably and effectively on older diesels with Bosch Ve-EDC fuel injection. This system uses the first generation of Bosch 'drive by wire' electronic injection pumps - the VP37 and similar 5 cylinder versions.(not v6)

NEW FEATURES:

1. Switchable hot start helper so its there if you need it now or in the future
2. Adjustable hot start helper – if you need to use, you can adjust the extra fuel mount for 20seconds during cranking to aid starting when the injection pump is worn or one or more heater plugs are weak to aid cold starting.
3. Selectable & adjustable off boost enrichment for weak injection pumps to improve low rpm performance and improve turbo spool up.  ** New for Feb '19 *** 
4. Socket for optional illuminated dash push button 'Sport Switch.' which gives an extra performance boost when needed eg for overtaking, towing or setting off up a steep hill. Now adjustable.
   

EXCLUSIVELY FROM TUNING-DIESELS - DIGITAL TECHNOLOGY WITH PROVEN RESULTS OR YOUR MONEY BACK ^{see below for conditions}

BENEFITS:

• POWER & TORQUE BY UPTO 25%^ FOR FEWER GEARCHANGES
• BOOSTS LOW DOWN TORQUE FROM AS LOW AS 1200RPM FOR EASIER TOWING^
• REDUCES TURBO LAG & IMPROVES THROTTLE RESPONSE FOR A MORE ENJOYABLE DRIVE
• IMPROVES FUEL CONSUMPTION when you aren't using the extra performance.*
• HOT START HELPER. The hot start helper gives extra fuel for the first 20seconds of cranking. Settings 6 & 7 enable this feature and the amount of extra fuel is now adjustable to allow for variations in pump wear.
• OFF BOOST ENRICHMENT: Three of the 8 settings (3,4,5) now provide adjustable off boost enrichment. This increases the output of worn injection pumps to improve performance when setting off and also means the turbo cuts in lower down the rev range. You can adjust the extra fuelling using the HSF control.
• SOCKET for the optional dash switch is now built-in which gives you the option of even more power for overtaking etc at the push of the button.

TECH INFO:

The brand new Synergy 4b uses 3 chips, one of which is a state of the art microcontroller making this a genuinely digital product. It uses 2 channels - one processes the MAP signal (unlike rival products - even those costing 3 times the price that only use the map signal to turn their box on and off) and the other controls the fuelling. 

The controls enables you choose where the extra performance starts and how much performance boost is available.

Fitting is straightforward: one cable simply plugs in between the map (boost pressure sensor) and its plug and then a short cable with a 2pin plug is attached to the injection pump wiring near the ecu, the Synergy cable then plugs into this. This is not rocket science if fiddly, but IF YOU ARE NOT HAPPY TO CONNECT TO THE WIRING DO NOT BUY. Full instructions are supplied.

 ^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.

PLEASE CONTACT US BEFORE STARTING A RETURN AS PROBLEMS ARE ALWAYS DUE TO FAILURE TO CONNECT IT CORRECTLY AND CAN BE RESOLVED WITH OUR HELP.

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

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, ow down torque and in-gear acceleration since they are always obtained on full throttle in 4th gear, usually from about 2000rpm upwards.  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.

PLEASE USE EBAY'S RETURN PROCESS BUT CONTACT US FIRST SO WE CAN RESOLVE ANY ISSUES DUE TO INCORRECT FITTING all our products are tested before despatch and well proven.
