ronbox vs other's

Looking into a tuning box at some point I have read how good the synergy box is but was wondering what the differance is to say something like this

Diesel tuning box Land Rover Freelander 2.0 2.2 3.0 TD4 | eBay

I no the answers are going to be for the synergy but someone must have tried the cheaper version

Thanx matt

but was wondering what the differance is to say something like this

that one ( http://www.ebay.co.uk/itm/Diesel-tu...tem5d2e4665cb&clk_rvr_id=579605571900&afsrc=1 ) has no tuning 'options' ..

the ronbox has 5 tuning levels/options for using with the bosch maf sensor
and 5 tuning levels/options to use with the pierburg maf sensor

each level is divided between 'torque' settings .. which translates to power levels @ under 2500 rpm
and 'power' settings .. w.t.t. power levels @ above 2500 rpm .. aprox. ( according to the ref. leaflet )

or .. if you've deleted the egr valve .. and are using the pierburg maf ..
you can use all 10 tuning options ..

the ronbox will compensate for a degraded bosch maf sensor if needed ..
or let you use the pierburg maf ..

the ronbox has a cab-switch that has has 3 tuning level options that can be used while driving .. ( for changing the 'box' settings the engine must be turned off )

the ronbox is made in britain ..

looking at doing the same thing and often wonder what difference there is
I know there are quite a few different boxes out the and there all considerably cheaper to
maybe it cos synergy is adjustable to your own choice I dunno really

a.f.a.i.k .. tuning boxs don't change the injector timing ..
that's something that can be changed with an ecu remap

i.e. as standard .. worldwide fuel quality is taken into account ..
but for uk diesel fuel the injector timing can be improved
( so sayeth internet blurb )

am under the impression that the maf sensor values change the timespan
between injector opening and shutting ..
i.e. that's part of what the maf sensor does on c.r. diesel engines ..
( although .. read that about another make of diesel engine )

I am not a fan of these "boxes" I had one when the first came out but not a Rover Ron, so I do not about his the one I had was adjustable ,although you had to use a small screw driver, I always meant to look what was inside , so I will find it out and look what is inside . but I do not think much ,the only thing I had with it is more split turbo hoses as it just puts more fuel through.

I was looking at these, but then a few people say they can mask serious problems with performance so that you don't notice until something is seriously wrong, I've always been a fan of remaps, just don't like how easily they can be deleted

I have a Ronbox. When I have new injectors I'll probably get it remapped. I am a fan of remaps. The Ronbox highlights issues that are present and often people think the Ronbox is the problem. It rarely is. My engine smokes because one or more of my injectors is on its way out. They have done almost 120,000 miles now.

Ronbox recons his box is better than a remap as he says it gives more at the bottom end than a remap. I'm not convinced. A remap can be tailored to the car.
Rover Ron also says his box can be used with a remap to give up to 165/170bhp. But only if the whole engine is in good nick

I'm on 121k now- so that's 10k miles on the Ronbox since I bought the car 4 months back. Yesterday I played with the Ronbox settings, but I still think the 10 setting is best for me as I pootle around normally, but like to have power when I overtake or climb hills so up the rev range is ideal.


One thing though- does the Low Med High refer to power or torque levels or rev range position of peak? Because even on low or medium settings it felt down on power to me than 10 High High.

Both..... The settings are marked on the box.... But you know that.

I'm running on 7 as my engine smokes too much if it is higher. I'd run it on 10 if the injectors were okay.

a.i.u.i.
'torque' refers to response below 2500 rpm .. and 'power' to what's above 2500rpm .. (aprox.) .. .. at least that's how it's explained in the ref. leaflet ..
and how to me it seems to operate ..
have done 38k on the synergy 2a .. have tried all settings .. and keep returning to '10'
with the pierburg maf ( egr deleted )
in the main .. for me .. it comes down to foot-on-pedal comfort ..
with the high-torque setting less pedal movement is needed for the desired response
i.e. response is more immediate ..
as for the higher rpm 'power' setting .. i prefer the 'high' .. 'cause it there when i might want to use it for a quick passing .. very very rarely do i use it in foot-to-floor mode

i hardly ever use the motorways .. .. but for that type of driving i'd prefer a lower 'power' ( 2500 rpm and above ) setting .. again for right foot comfort ..

have yet to hook up the cab-switch .. for me i could only see that being useful for rare 'm'way trips ..

I thought mine was quite pokey on 10. Then after I got mine off the tow truck, I took my mates DCi X Trail for a spin (136bhp). It revs light and freely like a petrol whereas mine feels a bit sluggy, and his really flies in 3rd. Hmm....

What they like on the l series?

The boxes are just as effective on the L series, there is/was a company called dark ice designs online that could fit the l series ecu with dual maps.

One map was for economy with the maf plugged in, and the other utilities a switch to disconnect the maf, putting the ecu in power mode.

Tuning Guide - Dark Ice Designs

they may not offer the service any more but it may be worth asking,

They do the synergy by the looks is it just as simple as connecting the box via tbe 2 plugs?

looks like the dont do the ecu chip anymore, might be worth dropping them an email to ask.

Good tuning guide though!

yes but isn't an x trail over £400 to tax and only does mid 20,s to the gallon

I have a Synergy 2e.

It has improved the overall mpg significantly. I have fitted the Pierburgh MAF.

I have not played around with the settings, just left it on 7 IIRC.

Would I buy another?......absolutely & I'd never try a cheap fleabay jobbie for the life of me.

That sounds like my TD4 auto -£475 last year, and about the same around town.

get shot then mate my td4 manual is half the tax and almost double the mpg

Commercial tax 220 i think mine was..
