Dyno run result

[Pukmeister]

From what I have previously read, the techlusion units can only add fuel over stock map settings and not remove it. As the modern boxer engine runs quite lean this isn't a problem.

If the rolling-road dyno agent has an air/fuel measurement device (and who doesn't?) they should be able to make adjustments to optimise your fuelling across the rpm range. The only question is how long it might take them to get it spot on and how many adjustments they would need to make.

I guess the answer is to find a local dyno agent and give them a call.

advise please guys

2010 dohc adv, full akrapovic & K&N

just dyno'd at 105 at back wheel

however air:fuel ratio was 14-15 to 1 across the range

rather than the ideal 13.1 ( so i was told)

dyno bloke reckoned another 7-10 bhp to be found when fuel enrichened

power commander & autotune thing seems a lot more than

wunderlich techlusion thing

as i only need to add fuel, should i go with wunderlich

at about 320 v 500+

or the original ecu remapped (scares me as when i sell i will have all the unused original bits, exhaust etc put back on)

only considering as i have had the "your bike is running dangerously lean" speech (aain)

any thoughts?

Can you test it with the original filter ? The K&N may make it run leaner. I doubt it would make a noticeable difference to the performance and removing it a lot cheaper than a £500 chip.

 

[Mysticwind]

thanks ape, the k&n feels better than stock, the dip at 5-5500 is less, so i guess its maybe not that...

you could also just try an accelerator module? It may or may not do the job but it is cheap to start with. I don't even know if you can remap the stock ECU but if you can I wouldn't as your warranty is well and truly over if you do.

I didnt know that someone was able to hack into the BMW ECU for a direct remapping and lamda shut off, yet.

http://bsd.uk.com/ for example does reprogramm original ECUs for various Ducati (Moto Marelli ECU) and Triumph models, but as far as I know, no BMW yet.

They fitted a PC on my bike instead while it was still under waranty, and the local beamer dealer didnt mind at all. No issues.

The issue is if BMW have an updated map, it will overwrite. Many manufacturers do release improved maps not just the operating code. However, as mine is a 2004 they probably wont bother with map changes now. All the same I think when I have mine done I'll stick a big label near the data port.

'The issue is if BMW have an updated map, it will overwrite.''

Oh no it won't!

Someone will no doubt argue the toss, but they are wrong!

I acquired a 2nd hand Techclusion black box and popped it on my 06 GS. I think I've erred on the rich side and it's running like a pig in places with some awful flat spots when you grab a handful - like trying to overtake in the mid range. Not bad at the top end though. Running Remus headers, Akra can and K+N filter.

It just seems a bit hit and miss pressing buttons and watching coloured lights in th ecomfort of your own garage.

Would someone with a rolling road + P.C. knowledge be able to get the Techlusion right?

hi Boxerboy
i have a 1150gsa 55 plate remus systerm,k.n and Techlusion
when i fitted all above i rebalance the t/bodies and vavle and end float
this made the bike run very well,and now i have a 12gsa 09 plate remus headers and short can std air filter and it runs crap....
so me going to fit twalcom full systerm wunderlich box .k.n and that should sort it all out



did skygods hp2 with twalcom sys and k.n full set up and runs sweet

check the vavles and end float then balance the t/bodies
then fit the tech box
all the best offroad god rudie

On what basis are you certain? Why would a BMW update not overwrite?

Because it's locked afterwards and a dealer can only download updates, which will not affect the remapping, they cannot unlock the ECU, as they don't have the codes to do so!

What it boils down to is this... get the ECU remapped which will give more BHP and torque and with the fuel air ratio adjusted correctly will give you more mpg and a smoother running bike, (if you ride it the same way) The bike will run better altogether, not lean or rich but just right, as it's now optimised for your riding style, or don't!

"Manufacturers adopt a one map fits all policy. This one map has to take into account many different factors that are necessary for each export country. Areas such as climate, emissions, fuel quality etc all have to be considered by the manufacturer. What this means is that a vehicle ECU is never optimised for one individual situation".

"The tuner will then tailor the map to suit before it is uploaded back to the ECU. By remapping your ECU it is easily possible to release extra power and torque from your engine"

Just look at post "Hilltop Motorcycles Earl Shilton" I went over when Micky and 3 others had theirs done last week, fascinating!

So what you are saying is the dealer can only upload operating system updates and the actual fuel map, presumably on a different chip, is locked? What if you change something and need it remapping? If the lock is not a hard one then I would not be certain that it will block BMW's programmer.

Certainly changing the map of the ecu would be a better way of doing it technically but the issue is more about any need to keep the standard ecu. I think if I had a bike in warranty I wouldn't want to mess with it and even on my old bike I prefer the Power Commander route where it can be easily removed.

Out of interest. What did your guys do with the Lambda sensors? Do they remap for those as well or remove them like Power Commanders. I'm not sure how the Lambdas are used. Do they use a map or an algorithm?

I'm just telling you what I was told, after all it's down to choice, if you are concerned about warranty issues then don't have it done...simples

All other questions ring Hilltop!

So according to you. BMW or their dealer network do not have the ability to unlock the ecu but these third party suppliers somehow have the ability to unlock the ecu and relock it whenever they see fit. An EPROM is easy to wipe clean.

I find this hard to believe

I'm just interested, I'm not trying to diss you or the method. It definitely would be the best way to do it if you could re-write at will and I wonder why it's not more commonly done.

Karlp, some re-writable PROMs have the ability to be locked against accidental writing either by requiring a special sequence to be sent or by setting a pin to 0 or 5v. Well they used to when I was involved with electronics but that was a while ago so could be wrong. If Hilltop lock it by changing a track on the pcb it is possible they could lock it from a dealer.

Ok Thanks

I have learned something new

I was told that a company back engineer the ECU to get all the codes, which Hilltop can then use to get into it and remap, and then relock, but it doesn't stop updates from dealers, just that they haven't ability to access the same codes to fully unlock.
