I repeat, I cannot believe I've ridden this bike so long without a chip! It's like a new bike, perfect!

What sprockets sizes are you using?

hornetrider · #17 Post by **hornetrider** » Wed Apr 14, 2010 8:48 am

Standard. 16/41 is it? The bike is on its original chain and sprockets anyway. 15k miles. Light came on this morning at 148 miles.

I can't be arsed to do the precise maths but this chip will probably pay for itself by the time I get back from Le Mans!

Thanks, I was getting that mileage with standard chip/gearing (I know, riding style etc), but I feel like the MPG's went down since I went -1 on the front sprocket. Anyway, I'll be testing it properly this weekend.

Yeah it wasn't a particular economy run - just normal riding over a long distance at high motorway speeds, with a small amount of A roads / stop-start town driving in there as well. I'm very pleased with the results anyway!

Of course, if you happen to have the right kit on your bike to allow the chip to work optimally, you don't need the PCIII.

It seems that Gabro is very good at making chips for whatever setup you happen to have (maybe if I didn't already have the PCIII, this is the way I'd go).

That's exactly my thinking, Andy. I acquired a Renegade chip and a Ti chip in an early burst of Falco-ownership enthusiasm, but haven't fitted either yet. At present the only difference from standard on my bike is a set of end cans, so it seems a bit premature to start chipping it.

However... There are mods in the pipeline. As I mentioned on AF1, Mark Chittenden is making a full system to match the Akrapovic cans I have, which will have larger diameter tubing in the mid-section. I'm also planning on enlarging the airbox and running a slightly taller and more free-flowing air filter to increase the internal volume and get better airflow. I'm toying with the idea of getting spacers made up to raise the tank 10mm or so to assist in this...

And lastly I've acquired a set of early RSV throttle bodies off eBay. At some point in the future they will be winging their way across the Atlantic Ocean to a Mr Ken Zeller...

Once all that little lot has been done I'm going to get a Gabro chip done. I don't see any point in doing it beforehand; far better to wait until he can tie it all in together.

Don't hold your breath on seeing the results, though. I doubt it will all get done much before the end of the summer at the earliest, as my time is fairly well mapped out for the coming months by SWMBO...

Mango - so you have 2 chips sat about doing nothing? Why don't you try them out,it's only a 5 minute swap job.

Once the bike comes back from Mark's, I may well do that. It's just that at the moment the fuelling feels fine, so I'm in no hurry to try and improve it. I'd also like to stick the bike on a dyno before I do too much, so I've got a baseline to work from...

I thought that too, how wrong was I!

How do you get in touch with the man making these Gabro chips ...........and how much ?

Cheers for the info will be looking into it ................more bloody money !!!

Bit hacked off.

Was at Le Mans at the weekend. Revved the bike up a little, then decided to take it on the Dyno there to see what gains Gabro had given me. Alas, my right hand SL Carbon decided to set fire to itself halfway through the run so it was abandoned!!

Was quite spectacular, spitting at first lfames then lots of sparks out the back! I have the footage on my camera so will upload it to YT for the forum's general amusement! Will take the opportunity to get both cans repacked I think! Was fine on the run home though.

I dont know how much my experience may help but I have curves for A Tuono (Tuoldo) that has gone from renegade chip to +PCIII to Gabro +PCIII.

This Tuono has a renegade 2 into 2 exhaust and a Renegade air box mod. I bought it with what was claimed to be a renegade chip. All I can say for the chip isthat it is not the standard and is a plain chip with +2 marked on it in black marker.

I added the PCIII at about 22,000 miles to smooth out the throttle response when winding on. This was achieved with a significant increase in MPG adding 10 miles to the warning light range (95 t 105) plus some extra power in the 7-8.5K rev range. The "smoothing" was successfull or felt to be. see below for the curves.

After a few words with Gabro on AF1 I had one his chips (V5 i think) put in in December ( I had added another 8k in miles over the year). The PCIII was left in and hardly touched as far as I can tell so the fuel mapping is still PCIII driven. Any change is soley down to Gabros igniton timing mapping. Gabro had had no experience with the renegade chip and so could not make any comment as to what change I should expect. The curves show a further increase in power. The fuel consumption (as one may expect) seems unchanged. The Tuono is now far freindlier in the very low rev range which has helped in town traffic and lazy touring (too idle to shift down some times). This is borne out by the curves.

The comparible power curves could be missleading. The old curve is taken from when the PCIII was put in 8000 miles before. The new curve is on a day with an increase of nearly 3% atmospheric pressure and a significant reduction in humidity despite a higher ambient temperature. However whilst there was a little more air to breath on the latter curve there was the added restriction of baffles IN. I feel like I have little more grunt in the mid range. The other noticable effect is that my exhaust system seems to running hotter than before. To me this is strange as I would normally associate this with a leaner mixture setting. I have asked for the fuel map but todate have not had the curve to see what has been actually done in this respect. As stated above i think the fuel map is very much unchanged.

Both retain a nice flat Torque curve which is highly appreciated.

Good info.

and interesting.

and welcome Tilt.

Just what i was looking for thanks Tilt ..........

Got intouch with the man himself yesterday and explained what i had and this is his reply ........

" 51mm TB's chips are not good for bigger TB's... to rich low throttle openings.
For this reason your actual Edwards "yellow label" chip is a little lean in that places (have you ever experienced cold starting at one cylinder only?), Good fueling in the other place, and good RSV ignition

If you go to 54's, keep it... will run just fine!
I've improved it, but you can save some money! "

There was a little more but nothing worth adding ....

Now i have to say that Aladinsaneuk had already said something along these lines so have to give him a full

Think i may have found some where down here that will bore my throttle bodies for me so hopefully soon i'll be refitting some 54's to my bike OR i'll be back on fleabay looking to buy some more 51's ................
