I would also check the settings on the unit too, I actually moved the power jumper back Mine was three from the right with the rpm jumper two from the right, I moved this back to 3 or 4 from the right, so lower power, and the car seemed faster, maybe it is a balance between getting the most and over fueling??

I am now very happy with it, after a tankful the car feels alot more alive than before. At first I wasn't so sure, the improvement with the 163bhp engine seemed a lot better, but now this has beeded in I wouldn't want to go back to the car without it.

The other day there was an Audi Avant to the right of me pulling onto the motorway, we both floored it as the lights changed and we were both neck and neck up to about 90, at this point he started to pull away slightly, and then I backed off anyway due to the speed, I have to say that I was a bit gutted and started to wonder if I was actually getting 200+ bhp even??
Then as he crept passed I saw the badge on the back.....

I had to have a little chcukle and I really wish I could have told him that I was in a 2.0 diesel.

So I reckon the Spider takes the 0-60mph time on my auto down from 8.3 to around 7.5 seconds.
I have an AP22, I must set it up and try it out.
What settings have you put in yours for the E92??

I don't think that the ECU can adapt to the Spider tuning box. The tuning box intercepts signals from the ECU and modifies these but doesn't change anything on the ECU - It can't as the ECU is secure .


Tuning Boxes have develped over the past couple of Years and offer more variable adjustments but to my knowledge no Tunng Box on the market can decrypt an ECU.


Your correct about the balance and the overfueling. You should get the fuel and 02 mixtutre to max and try not to inject more fuel than the 02 can burn - else that's when the smoking starts and the injectors can get damaged and the car goes into limp mode etc.

It's a smug feeling knowing that a modified 2.0d can keep up with a 3.0d

You should think about de badging your car - will keep most guessing.

[gIzzE]

I always debadge, even with the CSL, just looks cleaner on the back.

The car definitely does adapt, you can tell this by how lumpy it runs when you first plug it in, and when you go back to stock again.
I am not sure what it is doing but it must monitor the revs, fule etc.??

The jumpers are on the inside of the box, you undo the two screws and you have two rows, one is to increase/decease revs (not sure if that means idle, timing, rev limit???) and the bottom row is to increase power, so I guess that means the amount of fuel ??
I'm not technical so not sure how these things work, but presume that coming off the common rail it must monitor rpm and fuel and adjust, adding more fuel as you stab the gas than you get normally?

The Ecu will adapt. The box provides different signals to stock and the ecu tweaks to adapt to this.

I'd recommend disconnecting the battery for an hour whilst it's fitted and then you'll REALLY feel an adaption.

This will reset the gearbox too, so it'll feel nippier for sure !

Are you really sure that the ECU adapts to the Spider Box. I haven't come across this before. Every tuning box I have researched works on the principle of intercepting signals sent FROM the ECU before they reach the fuel pump / injectors - it's not a 2 way process so nothing gos back into the ECU - Right.

As for the gearbox resetting if you disconnect the battery for an hour.....?????? that's also new to me. Are you suggesting that the Spider box can adjust when an Auto gearbox makes changes?

There's obviously more to the Spider Boxes than I was aware

Next I'll be hearing that these things sharpen up the steering!

Ok theyre on the inside! Thanks! Did you ever tried max power on yours?

[gIzzE]

No, cause 3 from max (out of about 10 settings) was causing it to bog down.

If I put the rpm jumper on higher it was make a horrible pinking noise too.

Ok but you tried with lowering one step and you felt like it was quicker? A perfect time to use the AP22 and measure what gives the most

I think what SJ is suggesting is that the ECU will know something has changed as it gets lots of feedback from the engine/exhaust sensors and it could well change its own settings as a response to the different signals it is seeing.

As for the gearbox an explanation would be great

[gIzzE]

The gearbox learns how you drive, if you want it to become alot sharper you can disconnect the battery, the other option is the put the key in the slot, press the button so everything lightsup but don't start the engine.
Now hold the gas pedal down for 60 seconds, you should here a noise down by your feet when it has reset.
This seems to work on some cars and not others.

gizze,

I see that you are enjoing the extra poke from the spider box, the sprint with the audi shows that box is doing the biz.

Is your car an auto or manual m8 sorry if its posted elsewhere.

[dxb335d]

I want to see someone fit one to a 335d out of interest!

[gIzzE]

Mine is an auto mate.

[Dj Mastergrind]

I opened my box yesterday when reinstalling after service. The power jumper was set on 4 of 10 I changed it to 6 of 10 and the car feels faster...but I´m gonna do some more tests with the AP22 to be sure.

[deejaygee]

You need to know that the position of the Jumper is dependant on the car, the engine and the model. For example my unit as standard from Spider was set on the 8 out of 10 postion. You CANNOT simply increase the power right the way to 10 out of 10 as this will damage your engine.

Be careful!!

Thanks for your warning! I talked to Mike at Spider before moving the jumper and he told me that I could move the jumper but if I get problems I must reduce it back directly.

Hi
First post after learning of this thread on tyresmoke forums (thanks gizzie).

Am going to order one of these Spider chips. I would like to ask a stupid question

If this box is so good why are BMW not doing this 'out of the box' so to speak and making it factory default? Surley there must be a risk to this?

Thanks

[gIzzE]

They do, they slowly add more power over time, to get you to buy the newer model.

The 320d has gone from 136bhp to 150 to 163 and now at 177bhp. I am sure there will be another increase taking it to nearer 200bhp before the new model is out.

Another reason is insurance bands, emissions etc. etc.

That is why you are now seeing a detuned version too, called the 318d.

As long as they stay slightly ahead of the competition that is all that matters.

Audi released the 130bhp diesel and bmw came out at 136, Audi released the 140 and bmw released the 150. BMW upgraded to 163bhp and Audi released the 170bhp, so BMW upgraded it to 177bhp.

BMW release the 204bhp twin turbo, audi are rumoured to be bring out a 210bhp twin turbo.

It is all about marketing, if they released the 320d at 200bhp from the off they would have to design a whole new engine to improve things and give people a reason to review it again or for customers to upgrade.

[gIzzE]

I have chipped every car I have owned and not had a problem yet.

[gr4z]

Thanks gizzie. I guess a call to the insurance company as well is in order

Having never chipped a car before do they react with horror or less so?

[gIzzE]

Depends who you are with, and say it is a 10% increase in power at most, and that you are doing it because the MPG is meant to improve a great deal.

Any tips on debadging? The dealer refused to remove mine saying it would damage the paint work. Thanks

[gIzzE]

Nice warm day or a hair dryer to soften the glue.

Put a piece of fishing wire behind each one and slice down, you may get left with some of the residue so rub it off and polish.
