Must Go Faster V1

[Panzer Patrol]

Here we go again.

OK, most of you who have followed this saga know the score. Those who don’t, you have another five previous rip snorting posts to read. That’s where people rip the piss out of me and I snort back. I still haven’t had the chance to compare my bike side by side with another GS so I can’t really give any other feedback than from the seat of the pants. The bike does feel really strong. It pulls like a train and I find I am using a gear higher just about everywhere. In fact, changing down for most corners is a waste of time and impetus.

However, the object of the exercise was to gain more mid to top end go. I think I have achieved some of this but at a price. The price is vibration. It is noticeable above 5k rpm. There is vibration now, where it used to be smooth. I have checked and re-checked throttle body sync and they are spot on. Two things I have noticed is, the header pipes are going from blue to VERY BLUE. But the main thing is, when flat out in 5th or 6th, if I roll the throttle back, the bike picks up and pulls better.

To me this is a sure sign of running weak. Checked the plugs and they are showing no signs of carbon build up. If we take the bigger inlet tubes, the bigger outlet tub (take the baffle out of the Remus and chuck it away) it should flow more air, hence weak mixture. But…..the bike is fuel injected. Surely the engine would compensate for this, apparently not.

Doing some research I came across a number of sites where people have experienced this and the shortcomings of the Motronic 2.4. This link http://www.battley.com/miscpage_002.asp is a good example and worth a read.

How am I going to fix this. A new chip would be one way and seems to be a very popular way. However, thanks to Animal and others on this board I went in search of the Techlusion solution.

Techlusion have just released a new box built exclusively for the BMW motronic system. Instead of piggy backing the original system, the new one comes with OE fitment plugs which plug into the standard wiring harness and use the lambda oxygen sensor. Its all about closed loop and open loop systems, which is explained quite well in the link I provided. Anyway, contacted TTS today and asked if they had any in. The answer was yes and I was the first person to ask for one (smug grin). So its on the way.

The next instalment will be the fun and games I have with this little baby. More dials to twiddle with than you can shake a stick at. Confusion shall reign in the Panzer household.

Need to lie down now

keep it comming panzer this is better than any tv soap

 

[notadrop]

.....yeah! keep it coming. Sounds brilliant

Lean

Panzer

I'm not suprised if it is running weak.

I have the Ypiece , remus titanium and K&N.

Running it on the dyno showed it to be lean across the range.

I had the techlusion fitted and disconnected the cat which sorted out the fueling.

Now pulls strongly.

I suggest you get it dyno'd, and can recommend dynospeed (Essex).

I have my dyno chart somewhere.

Dave

I strongly suggest you get the bike dynoed

As promised the little Techlusion thing a meebob turned up this morning from TTS. Couldnt resist it, I just had to fit it.... So!

This gizmo has a male and female plug socket for the Lambda sensor and a male and female socket for the right hand injector plug. So all you have to do is disconnect the lamda socket and shove the appropriate bits in the right holes, same with the right hand injector. This system (R-259) is brand new and designed to run in conjunction with the original BMW Motronic system rather than piggy back the system like the original Techlusion. After plugging these bits in, all you have to do is connect the earth to the battery and perform a simple check to see if it is working. The hardest part of the operation was taking the tank off. Took maybe thirty minutes tops. One minor criticism is the wiring shrouds dont have a watertight seal (maybe it doesnt rain where they are made, it sure does here though) All it took was two minutes with insulating tape to seal the joints and hey presto!.

I only had the chance to take it for a short test ride, maybe 20 miles or so, up hill and downt dale.

Hubba chuffin hubba (Animal) what a difference. As I mentioned earlier, the gains came at a price and that price was vibration, both through the bars and especially through the tootsies..... Its gone!!!

It is as smooooooooth as it has ever been right across the range. In fact it is probably smoother, when pulling hard in 5th and 6th from low revs, than it has ever been before. Throttle response has improved dramatically and it really picks up and goes. Down changing is the best it has ever been, its like blipping the throttle on a jap four, just instant and smooth. I was completely gobsmacked.

I came home with a grin so big I could have swallowed the bike. Outstanding improvement without a doubt.... and this is all on the bog standard base settings, with no twiddling by old itchy fingers (thats me)

Outstanding little gizmo well recommended

 

[CoolCarbon]

Sounds Good

Panzer,

The unit sounds the Biz,

I have a straight through Can and a 'Y' Piece, oh and a K&N Filter.

Do you think it would do me any good??

To be fair, my GS is fine although there are a couple of small flat spots that could do to be rubbed down a bit further!!

Cheers,

CC

Hi cool dude.

Maybe Bandit is the one to ask as his bike has had the same mods as yours and he felt it was a big improvement. Gotta remember mine has Ypiece, Remus, K&N, carbon inlet pipe-snorkel thingy, RS cams and RS inlet tubes.

But on first impressions, abso-chuffin-lootley. This gizmo allows you to richen the mixture at the bottom, mid-range for acceleration, and the top end. It also allows you to set the mixture for cruise. You can gain the benefits of increasing fuel where you need it and you can lean it off for mpg on cruise mode. At least thats what it says on the box. Cant do that with a chip. And you can switch it off and the bike reverts to the standard settings.

I know....seems too good to be true...only time and faffing about will tell.

Keep the faith

 

[Shurv]

I wonder if this widget is the same as the one Wollaston BMW are telling me about. My GS is booked in next friday for the Y, K&N and Remus. They are telling me it is about £ 150 ...is this the same thing ?, or is the TTS route better. TTS are only about 10 miles from me and I was thinking of getting it checked on their dyno anyway. It also sound like some bikes are OK with the pipe and Y & K&N, but some are needing further fettling.




Confused from Northampton


Shurv.

 

[CoolCarbon]

Sounds Great,

So.........what's the damage ??

[Panzer Patrol]

Cool dude its 187 + vat. More expensive than the standard widget but its custom for the BMW.

Marcus my man, if I was you, I would head off to TTS and get a before and after on the dyno. It would guarentee your bike is set up spot on by the experts and....we could all look at the dyno chart and go ooohh aaahhh...so thats what it does

 

[roger monks]

must have missed the thread before,but where can you get these techlusion thingies and what do they cost!
will it fit a GS1100 that has not had a cat fitted or does it require the cat wiring to work (is the wiring for a cat there on my bike but not used?)
Has anyone heard IF and WHEN the dynojet powercommander will be available for boxer twins?

Techlusion

There is lots of info on their site :

http://www.techlusion.com/whatsnew.htm

http://www.techlusion.com/workstfi.htm

http://www.techlusion.com/bikepages/bmw/r1150/index.htm

I have the standard TFi 1030 box, cost $189.95.

I am not sure of all the differences between the 1030 and the R259 but

The R259 looks a lot easier to fit, with plugging into standard fittings, wheras the 1030 requires splicing of wires.

Also the R 259 uses the o2 sensor, the 1030 doesn't, the onlt benefits I can see here are on the 'cruise' mode.


I fully recomend making the change, throttle response is much improved, as is smoothness.

I will get a copy of my dynocharts and post them this weekend.

[glenwatt]

I thought I'd post here as the other thread linked to this one anyhow.

I can confirm Panzer Patrol's findings above.

So far I am very impressed with the results after fitting the R259.

Surging seems to have gone too, final test will be through London tomorrow when the bike really gets warm and the surging normally got more noticable. I'll keep you posted.

All this with just the base settings and no dyno as yet...!

 

[Shurv]

I'll call TTS tomorrow and see what they can sort out. A before and after dyno would be the bollox........I'll keep the forum posted.

 

[glenwatt]

Guys,

As reported before, with the unit set on base settings, confirmed using a volt meter as per the instructions.

Very positive results, even through slow traffic with the temp gauge up at 6 bars. It's like a different bike.

Marcus, I'll post on the other thread, as I too would be interested in the dyno results and any differences they may come up with from the these base settings. (you never know there may be more improvements to be had ? )

 

[Finbarr]

Running lean - what's the end result?

I'm just a bit curious - if the bike was running lean from the factory to pass emmisions tests, and we then take out the cat, put on a free-er pipe and a free-er breathing air filter, we have to assume that the bike is now running "quite a lot" lean...

What is the impact on the engine of running this lean for extended periods?

Obviously, the engine will run hotter, but will the valves burn out, what damage will be done to rings/piston/cylinder/plugs etc from this lean condition? Are there any other implications to this?

Kind regards,
Finbarr.

 

[Panzer Patrol]

My thoughts exactly.
One can only hope that the "famed" BMW engine toughness can take this sort of abuse. However, with the advent of such wonderous things as web based forums that magic balloon has a chuffin big hole in it now.

Only time will tell.

Remember, theres no point in whinging any damage is self inflicted.
