Some background: I have the 2-into-1 exhaust conversion with a Mivv GP-style exhaust, a renegade-style open airbox and a PCIII fitted.

Now in March I had a custom map done but I really dont like it. Firstly it hits reserve after 90 miles, secondly it is not smooth below 3k revs - it hunts and jerks and shudders until i give it more juice. The mid and top end power is fantastic though... smooth creamy power.

My question is... is it safe to download maps from the internet and other pcIII users to experiment with? Or will putting the wrong map potentially cause some damage? i.e. if i try a map thats much too lean or much too rich can the engine be damaged?

As you know I also have a 2:1 exhaust and a PCIII but not the Rene airbox.
I've always planned to get a custom map but not got round to it yet.

I've downloaded a number of maps from Dynojet's site - some were awful for my setup.
I'm currently running a Tuono map and it's cured the extremely rough running below 3k and most of the embarrassing cannon-shot backfires that I used to get (but not all).
On short commutes (3miles or so to work) I get about 100 to 110 miles to the light. On a long run about 140 miles to the light.

I know that Martin Poll is also hosting a number of PCIII maps on his website:

I run a similar setup but with two cans. Currently I am also using a think map from a german bike ..... No problems but I will get a proper map done again.

I also know paddy has played around with maps and changed them

3 miles to work? Lucky sod

Thanks for the maps... i will add them to the ones i downloaded from the PC site. I take it you are not worried about potential damage from a map?

Can anyone suggest a good dyno centre? Im prepared to travel cos all the ones by me see either dodgy or are only interested in race bikes.

Personally, not too worried about damage from maps - they've all been designed for similar bikes and I think you can tell pretty quickly if it's not running well. Also keep an eye on temperature gauges and check your plugs if you are worried.

That said, I'm giving no guarantees.

Wish I knew a good dyno centre from a bad one - this is something that has been holding me back from shelling out to get a custom map done.

I reckon if we knew of one we could all get together and hire it for a day or half a day and a good number of us get set up. First we need to find a place we can rely on.

I did notice in a recent PB an article where Ben Wilkins was working on the set up of his long-term test bike. It included a number of exhaust changes with PCIII setup runs and seemed to give good results. The "how much this costs" bit at the end was interesting too ... the dyno cost was under £50 .... I've always been quoted between £100 and £150.
Think I might try e-mailing to find out whether this is right, a misprint or that I've just got hold of the wrong end of the stick.
If it's right then further investigations will begin ....

You might be on to something here.... if we can get 4 or 5 Falcos together we might be able to make a deal and an event out of it.

Running rich won't damage the bike, only the planet, running lean can damage the pistons so don't do it for long.

I got my PCIII setup with these guys http://www.motrac-racing.com/dynojet.html and the bike's been great ever since.

I had previously tried loads of maps off t'internet but none worked very well.

Dave

I'd be up for a joint dyno session...and run out of course!

Oli

I could make enquiries at seastar for the Friday before the Norfolk meet......
