JohnGS1100 Tuning Chip

Roger, dual or single spark does no matter (for idle speed). You are right, boxer engine feel better at 1100 rpm, the oil pump work close to correct pressure.
But the old BMW boxers are very very strong, I do very hard test !!
Withstand functioning at very low idle (900 rpm) for 20 minutes, the temp go high (7-8 lines) and the engine work correctly without problems and damage..

Is that parliament square in Athens John? I think I recognise it, I used to catch the bus from there to Phaliron when I was a schoolboy. That was 40 years ago!!!!!!!!
Merry Christmas to yourself and everyone else!
 
Yes is the parliament square in Athens :). nothing has changed for 40 years.
I think at the end of this year the whole world press will talking about this parliament square.
I hope also at the beginning of next year, the situation change for the better in Greece.

Marry Christmas to all !!

Hi John. I have small query ...
At moment I'm working on 1100rt project should start engine next week or so , if I get ECU for 1100rs or gs will you make chip with mapping for 1100rt, can I use then that ECU on my rt ? And keep original as backup ... is ECU s I interchangeable besides diffirent mapping ?
Val
 
Yes friend. I can make a chip based on RT or GS maps, i want help your project. Let me know for details at my email . :thumb2
 
Hi All,

I'm thinking of fitting one of John's chips to my 1100, which suffers from bad surging.

One question: are you guys telling your insurance companies when you fit the new chip, when they ask 'have you made any modifications to the bike'? If you did, how much difference did it make to the premium?

PS - sorry if this has already been discussed, I did search the thread for 'insurance' though.

Cheers

Dave

There are no changes or alterations in function of the ECU of the bike.

So i think that there is no problem Dave.
The new chip in ECU is on the base exaclty like the stock original chip. No needed any modification at electrics circuit.
Also the results comply the emmision EURO standards CO, is simply an upgrade that improves the smooth operation of the engine..
 
Hi john, I' m interested in one of your chips. It would be to fit a 1998 uk model r1100gs, no cat, std exhaust and filters however it's been fitted with rocket sprocket Cam sprockets From Lennie of www.boxer-performance.com please see below for his explanation of what they do and how.

The Rocket Sprockets are 9 degree advance cam timing sprockets to fit all BMW R series twins, the cam in head models from R850 to R1200 up to and not including the twin cam models. These sprockets move the torque peak 800 to 1,000 rpm lower in the rev range improving throttle response and less need to downshift for all types of riding.

I have to say I have been delighted with the improvement they made to the bike, if I fiitted one of your chips what could I expect to see? I wouldn't want to ruin\loose what I've already gained.
Many thx
John
 
Hi John,

Thanks for that - regardless of the insurance position in the UK, I've just sent you an order for a chip for my bike. Looking forward to enjoying the bike again.

I've had an 1100s is the past, which had a fabulous engine. I have been very disappointed in the 1100GS, it's not a pleasure to ride at low speed at all. Only taking out the CCP makes it a pleasure to ride, but at the cost of terrible economy. It's just running very rich I guess. I'm amazed that BMW got away with releasing such a flawed bike!

Cheers

Yes i made a special chip for mods sprockets. This chip gives little faster timing advance at low and middle revs of rpm, but gives also slowly timing advance at high, because the stock chip by 9 deggress camsprockets is dangerous for engine at high rpms.
So by this mod chip the torque will be much better at low, little better at middle rpms and the power will be safe at high rpms.

Thanks Dave. When remove the CCP at R1100GS with CO-POT function (no lambda) you make the AFR little richer. So needed to fit large injection intake tubes (RT-RS). The problem as i saw at stock chip, is that the AFR (at stock chip) is very lean at low, little richer at middle and lean at high rpms. So you have bad torque at low rpms and bad consumption when you drive the bike at middle rpms..
I made corrections, so the chip that i send to you resolve all these problems. You said to me, that your consumption by the stock chip was 35mpg. Try the new chip and let us know :)
Regards
 
Hi John

I'm afraid my knowledge of modern motorcycle mechanics is zero - so bear with me.

I have an 1100gs with no cat and a remus. It always ran fairly well but was prone to a little surging from time to time. Someone told me to take a plug out of the fuse box, which I did, (don't know what it was called or what it was for :blast) it now runs really smoothly but very rich (MPG has gone right down and you can smell the rich fuel).

I guess one of your chips will sort this - in layman's terms - am I right? and if so which one.
I'm not a racer, just want a smooth bike with good fuel economy.

Many thanks
 
Hello gspod

Your friend take out a plug called CCP from fuse box. When you take out this plug the fuel goes to richer, much richer.
The solution is to fit again this plug and fit a chip stage 5 for R1100GS, this chip resolve the lean fuel by de=cat and after market exhaust. Let me know for details at my email, [email protected] :) Thanks.
 
Hi john. Time for one of your chips. The 1150 needs a bit of the r850r's enthusiasm!
 
Hi john

First run out yesterday with chip fitted and really pleased. I've been riding the wife's 800 all week and usually when I get back on mine the sluggishness is very noticeable and I have to really wind it up. Not this this time, it's much sharper and quicker through the gearbox. I shall be checking the fuel consumption during the week ahead.

Cheers
:beerjug:
 
Thanks for info :)


Let us know for any problem, for cosumption and any other.
 
breathes better and makes the bike lighter makes the gasses leave the bike so much easier I recommend it done it with mine and also makes the bike sound throatier ohh yesssss
