Fitted mine and taken for a spin - about 30 miles so far. Not noticed much yet - should I?

[dxb335d]

Then its doing nothing. Either its fitted wrong etc.

It should give you over 210bhp which WOULD be noticable from 177bhp let alone the torque.

Hopefully someone will come along and help soon.

As Carlos says you should notice the difference.

Doesn't the spider come with different levels of adjustment?

I would have a chat to spider and see if it is on the right setting

[scotw]

It does come with different levels. They had me try various ones with my first one and it would not work, so they sent a new one. To be honest I can't really tell the difference, so I think they set it on minimum to make sure it worked (this was after several weeks of problems).

Waste of time in my opinion, it'll go on ebay when I can be bothered. I've seen no power gains and no economy changes (in fact it seemed slightly worse after fitting).

[Budgie]

Funny ...i know mines there..even though the power is very linear i know its there.When i got mine off mike i asked him to set it to the limit and he confirmed he did this.Get it in say 4th and let it rev up a little and ull know if its there as the accelaration is very evident.

You can always send it back to mike he is a great bloke and wont have any hassle in changing it or even inviting u to Hull to have it fitted and tested by Spider themselves.

[gr4z]

OK burning some rubber today and I reckon its working...from 30-40ish upwards you can definately notice something has changed. More poke when you put your foot down. Havent done enough miles yet to chk MPG though. Thanks for the advice guys.

[Cafe.Racer]

Hmm, I don't have a spider box, but I can definitely feel mine's working - there's a significant difference.

I can't remember the gears and timings, but do something like stick it in 4th, boot it from 50mph, then time how long it takes from 60 - 100. Do it with the box on and off.

[Budgie]

Yeah i agree u dont tend to feel it till u get in 3rd 4th 5th and 6th.It does actually take around 250 miles to settle in and then like Cafe Racer says ...u can feel the difference.

Keep us updated

[dxb335d]

If some of you aint ''feeling'' it then i suggest you get the car rolling roaded with and without the device on the same day. If it does not improve by much, go the Re-map route.

It might be a bit soon for that - it might be connected wrong, there might be something wrong with the box (not the first time, from reading on here), and there are other boxes out there...

The original 'Tuning Box' on my wife's 320d (166) makes a big difference to the car. There is no question as to whether it is in or not.

The guys are discussing a "spider box". It's a plug in tuning box that enhances the the performance of a diesel engine whilst improving mpg (under normal driving conditions).

Typically a spider box (or tuning box) will increase both bhp and torque by around 15 - 25%.

Wikipedia says
Spiders are predatory invertebrate animals that have two body segments, eight legs, no chewing mouth parts and no wings. They are classified in the order Araneae, one of several orders within the larger class of arachnids, a group that also contains scorpions, whip scorpions, mites, ticks, and opiliones (harvestmen). The study of spiders is called araneology.

sorry just could not resist.

Seriously
A Spider is a tuning box that you plug into your engine management system (ECU) and throttle sensor. It intercepts the throttle position and then passes it onto the ECU. The ECU then sends signals to the fuel injectors as to how much fuel should be pussed.
What happens all depends on the engine speed (in RPM) and the Throttle position.
Basically BMW set up a map and put that in the ECU. e.g. engine = 2,000 rpm and throttle = 50% then squirt 10 whatevers of gas into the engine.
Spider says that's ok but to get more go here we need +3, to what the ecu says.
This way you don't need to remap the engine, but just plug in a box to the engine and it has the correct settings for your engine already in it.
There are advantages and disadvatages to either route.

I'm sure there are many threads here trying to proove either route.

whats a disadvantage of a re-map then timsta mate?

1. That it can be over written during a service
2. That it's non adjustable (unless you remap again)

Have you had yours 'boxed' then TI?

I have been going through the Box/Tuning debate and feel that as you say there are disadvantages of the remap, it is probably the best way to get the most out of your engine.

As the tuning box only adds more injection pulses or varies the rail pressure it has no control over the turbo boost so I think you are limited to bottom to mid range improvements where the remap can give the higher end gains as well.

Please correct me if I am wrong its only the different things I have been picking up and nobody has ever put a tuning box on the dyno.

One of the guys used a tuning box for low end improvements and a rempa as well to get the best from the top end

Yep, that's about it.

Non adjustable? it does not need adjusting. Its set up perfectly first time round. Re-mapping after a service is not even as hard as refitting ya box.

[Ti Rich]

First of all let me say that I have used both methods and am not saying either is better than the other - i don't want to start a war!

Secondly my current car is not remapped or "boxed" so the experience i have is based on previous cars.

One significant advantage with a tuning box is that it is adjustable by the user. For example, if you add a performance exhaust, de-cat and EGR by-pass to a diesel then the chances are that a bit more fuel can be added. With a tuning box this can (normally) be done instantly. A remap (or a re-remap) can also achieve that same but requires a specalist equipment as it will require a custom remap.

In my view as well a tuning box tends to give more torque low done in the rpm range when you are not running at maximum boost. The higher fuel rail pressure appears to give an advantage here. Remapping (which gives a longer injection pulse) tends not give the same effect at low revs.

Remaps tend to give a more progressive power delivery.

As i have mentioned before. I have used a mild remap AND a tuning box to give maximum benefit! I don't say one is better than the other!

[CrimsonRedE93]

Well put Ti Rich, Is it painful sitting on that fence

Ti rich, could a tuning box be used with a re-map on a 335d?
