I had a performance chip laying around my garage that came with a bike I had last year. In all honesty,I couldn't be bothered to fit it. The recent acquisition of a 26000 mile K100RS 16 valve and nothing better to do this morning was the ideal time to fit the chip.

Performance chip K100RS 16 valve Cimg2328

What a difference!!
It's a different bike now. It's got great mid range and it revs. I saw 9000rpm in top gear without much effort.
The bike is a little snatchy in traffic just off closed throttle but I'm OK with that-it seems like a fair trade-off for the difference it's made.
I don't know what is done to the fuel economy yet.

What are your thoughts on these chips fella's?

Hey Mike,

That is a beautiful looking RS you have there and only 26k miles - wow!!

9000 rpm though - zikes!! is that good?
I don't think I've been over 6000 rpm on my humble 8 valve LT

I have Harman chips fitted in both my K1 and 16V and find them very effective. I also have a BBR chip but have not had a chance to test it yet - what chip do you have ?

I put a Harman chip in my K1100 and it was to put it mildly bloody pathetic. It could not have pulled the skin of a rice pudding. Overfueling below 4000 and over 4000 (if it got there in 5th) it was absolutely hopeless.

I might need to get Dai (because he's also got Moto Guzzis) to come in here and comment.

The V7 came with a O2 modulator (Motociclio) which is essentially a chip that changes the lamda ratio, and is used to counteract the lean fuel mixture that guzzis arrive with.
I got on the Wild Goose forum to check it but before fitting but the response was a huge DON'T. Told that all but the most sophisticated of chips generally supply the extra fuel over almost the whole rev range which is not desirable.
Pete Roper who is an acknowledged MG guru told me to bring the bike to him and said he would upgrade the ECU map, which he did and it's running much better. Told me to chuck the spoofer in the bin.
He has a Stelvio in the workshop where a guy insisted on running a spoofer and the overfuelling washed the oil off the bores.

I once had the rather stupid idea of getting a chip for my diesel ute but found out that it was primarily going to increase the pressure in the common rail to the detriment of engine longevity.

So it would seem that these 'performance' chips are questionable and require fairly expert opinion on their use.

You can't lose with Pete Roper. I remember watching him race an AJS at Thruxton twenty-eight years ago affraid

Yes, most 'performance chips' are very definately questionable. Almost anything that's cheap and promises to increase power with be chucking fuel into the bores and bugger the stochiastic (??sp) requirements. There are a few exceptions: the German-produced chip I have in my Cali 1100 does a specific job of increasing fuel at the 2500rpm mark which is where the noise/emissions tests are done. 80% or so of the 1064cc Guzzi engines have a seriously irritating intermittant misfire at that rpm point. There's also a very-well thought of Guzzi 1100 ECU upgrade done over in OZ which I have my eye on for my 1100. http://www.myecu.biz/MyECU/index.htm.

The only chip I have ever come across for a 16v engine was from Staintune to be used with their pipes and all it did was correct some slight flat spots that were caused by the pipes. You got a slight increase in HP and the midrange throttle control was better but there was no huge mind blowing increase in power.
I have been reading up on the mega and micro squirt systems and to be quite honest you will get some good improvements but in tuning you will have to spend hours on a dyno and several hundred hours on a track and be prepared to probably destroy several engines to get it spot on. I much prefer to accept the Bosch/BMW version of the software it works quite well for me.
I put the K1200RS cams in my K1100 and after some tinkering it became blindingly obvious to me that some serious remapping of ignition and fuel was needed to make it a sweet ridable bike so out they came and got sold to a local who thought he could do all that in 20 minutes, I haven't seen seen him since so I don't know how the story paned out but I think he just wanted the monster that mine became over 5000rpm and stood up at every opportunity. And he is welcome to it.

stiometric is the word you want, I think.

Yes, He knows what he's doing and over on the WG there's an interesting thread relating to cam damage on the 8 valve engines. He feels sufficiently confident to advance the argument that it's climatic.
They (plus his mate Beetle at Wagga) have not produced a map of their own for the single TB (V7) yet. which is what they've done for other MGs. I get the dreaded 404 for that link.
He offered to 'escort' me out of Bungendore, a small country town near Canberra, and got out an 8V Griso.
He went past at more than 160kph (country road!!) and left me for dead. Since I needed a licence to get back home and perhaps unlike him, didn't know the local cop, I refrained from joining him.
However, if caught, he could have said with some truth. "Who me Sir, I was just getting the oil hot, that's what you've got to do with these bikes else........"
He's an AUS legend.

The chip only has a part number on it which I didn't make note of before I screwed everything back together. I will take a look at some point and give the number.
There was certainly no makers name on the chip.
I'm building a JJ Cobas Flying Brick and I will definitely be installing a chip in that bike.

Performance chip K100RS 16 valve Cimg2329

As per some of the replys on this thread,it's plainly obvious that the chip is tipping fuel into the engine but for now it works and I'm happy to let it do that.
I found the RS very hard to ride quick pre chip because it just wouldn't pull through the revs. I had to down shift and rev it like a 2 stroke but now,it's a pleasure to ride and I'm looking forward to upsetting some riders on modern bikes.
Suspension mods next as the rear unit is very crude at speed.

I added a Power Commander PC-V and Autotune to my Moto Guzzi V7R with the intention to enrichen the lean fueling from the factory. Without it, the bike was very cold-blooded. At first, I tried the O2 Modifier that came with the PC-V but quickly discarded that based on feedback from the Wildguzzi bunch. The Autotune has transformed the performance of the engine, contrary to what others have to say about Dynojet stuff on Guzzis. Now the engine is smooth across the entire power band and exhaust pipe bluing is reversing itself. So, not all aftermarket performance enhancing products are snake oil.

stochiastic (??sp) requirements
stiometric is the word you want, I think

At the risk of sounding smarter than I am, I think the word is stoichiometric.

Stochastic is a term used in some pretty esoteric statistics, one use of which is, I believe, the modelling of stock market performance charts.

Stoichiometric is a chemical term for the presence of exactly enough of two or more components that combine chemically so that the reaction proceeds to completion with no leftover of any component. In the burning of petrol in air, stoichiometric is about 15:1 air:petrol.

Earlier carburettor engines were usually a fair way off this, but fuel injection systems get much closer, especially if there is feedback via an oxygen sensor in the exhaust. The complication is that any internal combustion engine is a very poor environment to try and get complete combustion, and the requirements that go with acceleration, high revs, maximum power output etc. make it even more complicated. The fact that a good fuel injection system gets into the 14s is damn good in the circumstances.

I rode the RS again today after 4 days off.
2nd opinion; Brilliant! The bike goes so well in any gear and make it's own ridiculous progress with all it's new torque. It's been a real surprise glancing at the speedo now and again when you get sense of the country lanes rapidly disappearing behind me to see 80,90, even 100mph on the clock.
My K is now a fast road bike that other riders will be taking very seriously this summer. Performance chip K100RS 16 valve 212902

The bike is little heavier on petrol than before I fitted the chip but it's well worth the loss in mileage as I'm having so much fun on the Brick.

I've no idea who made the chip that's in my RS. It was given to me with the bike and had no makers mark,just a part number which I suspect relates to the chip's manufacturer.

I found this one on eBay and thought I'd give it a go (as it wasn't expensive) in my Cobas bike. I'll be able to swap and change for the best one that suits either bike but my main interest will be the Flying Brick.

I've looked a fuel consumption and can report a low of 40mpg when I'm riding the bike very hard solo and a best of 50mpg with a mixed of motorway,country roads,all done with the Mrs on the back.
I'm pleased with those figures.

I can also report that the motor has begun to free up. What? I hear you cry. Well,the bike had done 26429 miles in 24 years which averages out to 1101 miles per year so I figure it's had an easy peasy life.
Since I've taken ownership of the bike and started riding it fairly hard,the engine really does seem to be loosening up.
I've questioned my sanity on this point but even the Mrs says she's noticed-so it must be true. Very Happy

Any thoughts Gentlemen??

That's not possible without changing the gearing of the bike. No level of engine tuning will change relationship between engine revs and road speed.

Seriously though, this chip has really smoothed out my performance and reduced vibrations (non-existent now between 4K - 5K+rpm. And 300 miles later fuel consumption seems about the same (hard to be exact with a pooched Odometer though). Magic is magical :-)

I'm not sure that a chip could do that on a K because the signal comes directly from coil to the tacho and the ECU should have no bearing on that signal and the pulses to the coil have to be kept in sync to the engine or havoc would be the outcome. It is possible that a cleaner signal occurs but the tacho has a conditioning circuit so I would not expect even that to cause a difference.

Well...after about 1500 miles of riding with my 'new' performance chip I must say I'm very pleased. The group I ride with (Bucket List Motorcycle Club) measure their fuel economy by "How far did you go before the reserve light came on?" kind of challenge. Well I had two runs (all highway averaging over 100kph) one with 232 miles to reserve light and the second to 238 miles. Previous to this, reserve came on just before 200 miles so with the increased mid-range performance and perceived increased range I'm quite happy! Smile

No...but I'll get right on that. I'm sure I've got an app for that in here somewhere ;-)

I'll explain further/better: I live in Metriclandia (Canada) and so all speeds/limits/tickets and my GPS all function in Meters/Kilometers and k's per hour. But my K100RS was made for the US market (who said they were going to change to Metric in the early 70's which prompted Canada to do the same - at great expense (I worked in a machine shop at the time) but they lied Mad

) and so my Speedo/Odo measures/indicates in Imperial and m's per hour. Hence the mixed metaphors, sorry about that.

There's a name for that condition, the word ex-capes me at the moment, lol!

My mates ask in miles too, btw, just because we're all over 60-70-...years old Smile

Good! It's a pretty simple change-out, I used two Tupperware orange peelers (inserted under the OEM EPROM from each end) to wedge the chip straight up so as not to bend the pins (maybe chopsticks would work). You don't want to short out across pins with metal. Also, the metal used for the pins while very ductile, could even break off if bent too far over. Embarassed

I live in both those worlds too Ace - started school learning imperial and along the way they changed it up to metric. Imperial rules the construction industry that I work in but the building code is in metric. Twisted Evil

How many litres are usually remaining when your reserve light comes on? Based on the the consumption of my 2v I would think that 230 miles would be close to empty for me. I've got the warning lights for 7l and 4l. Only the 7l light works and it will come on at around 230kms. Do 4v bikes typically get better mileage than 2v's? The chip isn't an option for me but I hope that this winter's shut down and overhaul will result in better mileage next year.

Hello Welland! I caught a beautiful 4' long Corn Snake there hiking by the locks - took it home to my place in Galt (where I was working in a machine shop circa 1973!)

Funny...that. Metric is so much easier - learned my way around that going to high school in Mexico City. I've been a Canadian Boilermaker for 36 years this year (37 comin' up soon, gulp*) and rarely do I see metric measurements in the field - except elevations! So you'll likely find a 24" nozzle (M3 say) manway at 62388mm above grade. More mixture of metaphors, like it's just all one big metaphor (lie) anyway Wink

Can't answer your question about performance comparisons between 8 & 16v as I'm very new to this brickhead status. There are many here before us who WOULD know. I could presume...but then they hate it when I do that, lol!

Before replacing my EPROM with a performance version, I was red-lighting (4l) at or around 200 miles (twice - then my Odometer crapped out for awhile). Got the Odo working again after changing the EPROM, and the best range I've gotten so far was 238 miles before the reserve light lit up - about 3 and a bit hours of high speed twisties in southern BC. I don't do much city riding, living in some schticks as it were. Also my vibrations are way down - especially within that so-well-used zone of 3000-4000 rpms. Used to be torturous in there. Now that's not all performance chip of course - 15oz bar ends and the washer mod on the riser assembly that someone suggested also helped with that. Do what you can do, tune-ups work! But unless I have some sort of massive failure, that OEM chip will never be re-installed Smile
