Power chip help, R1100GS , 1994

[Jamie s]

I realise this has probably been done to death on here so I will start by saying I'm sorry. I just want to make sure I have got my head around this properly incase I bugger anything up.
My bike came with an Eprom chip, says "open inlet/exhaust" on it, (came with no instructions ) so I just threw it in the motronic unit, at the same time I fitted a Remus can and K and N filter. (The bike was STD when I bought it but I believe the guy before me had fitted all this previously)
The bike runs great, and has a lot more "go", I have had it on the dyno and it's making 84bhp.
Now Iv'e been doing a bit of reading up on here and it seems there is different maps that the chip is capable of (only just found this out) so going by These instructions then my bike which currently has NO coding plug , this would be set up for "use with special camshaft", which is clearly not what my bike has.
So would I be correct In thinking that I want the bike set up for "aftermarket muffler", stage 2, pins 2 and 6 connected?
My bike has a yellow CCP, it has no cat/ 02 sensor on it.
I only ever get around 160 miles to a tank, could having it set up the way it is be causing this?
The bike is an Import (not sure where from, numberplate says "jap motors", so I assume Japan), It was made in 1994 but is on a p (1996 reg)
Regards, Jamie

I know nothing about tuning chips but my 2p is that if you want to turn a 17 year old 1100 in to some sort of rocket ship, you've bought the wrong bike. In standard form they 'work', once you start bunging on aftermarket tuning gizmo's, you're opening up a potential can of worms - there are a lot of variables and you've no way of knowing what effect the various changes you've made are having.

At the very least, I'd take it to a dyno and get them to test the fuelling to make sure the mixture is within spec.

BTW, my standard, plastic tanked '94 1100 gets between 50 and 55 mpg fully loaded in mixed riding. I usually fill up at about 200 miles which equates to 2 or 3 bars remaining on the gauge

You should always give it a good test run after each "mod" other wise you will never know what works and what dosent so put the std exhaust back and the air filter and see what happens either yea or nay but you will have a bit of data to work from.
