bbpower chip instructions

[essjay]

Anyone have instructions for their bbpower chip? I guess they are the same for the 1100 as for the 1150.

My bike has one installed and from what I can see, it seems to be connected wrong. The best instructions I could find online are here:

On my bike it seems that pins 2 & 6 are connecting so according to those instructions it's set for "with or without cat low octane fuel". What's low octane fuel? Surely anything in the 90's (which we have over here) is high octane?

If anything it should be wired according to the 5th from top image - "aftermarket muffler" as there is a Remus box and pipe fitted.

So I want to put the OEM pipe back on - which map do I go with? Some of the maps have no description on them. "Stage 1" - what's that?

Last question - how do you wire 3 pins together?

<91 is low octane according to bmw

this is the instruction sheet for a BB chip for the 1150

No, they're different - Cookie has posted the 1150 one but your profile says you have an 1100 so the one you found is presumably what you need?

Pins 2 and 6 connected is Stage 2, for use with an aftermarket exhaust - you're not reading the diagram right. The stage number and the description immediately below it relate to the diagram above.

So I want to put the OEM pipe back on - which map do I go with? Some of the maps have no description on them. "Stage 1" - what's that?

It tells you on the diagram you linked to - Stage 1 is "for models without catalytic convertor". Which map you use depends on whether you have a cat (in which case the mixture can't be too rich othewise it'll damage the cat) or a mixture pot (in which case it doesn't matter).

So it looks to me as if you need Stage 1 if you don't have a cat, Stage 1a if you do have a cat.

Last question - how do you wire 3 pins together?

You need to make up a jumper - two short bits of wire, three spade terminals. Crimp an end of both wires into one of the terminals, and then one each on the two free ends. Now you can connect 3 pins together.

The chip would have been supplied oriignally with a 3-way jumper as well as a 2-way one (mine was) but it's probably gone missing along the way if it wasn't used for the previous owner's setup.

Ah ok, penny drops. Thanks a million Sproggy - I was reading it arseways.

So yes, it definately looks like a "Stage 1" if I put the OEM 1-piece pipe back on. I suppose the next job is to look at the pipe and see does it have a lambda sensor. According to this diagram it does (part 6):

only if it's an 'import'.

I wouldn't have thought an irish 1100 would have the cat.

It's a UK bike - first registered by Blue Bell BMW December 1998.

Daft question - how can I tell if it has a cat or not?

If it has a cat then it'll also have a lambda sensor attached to the exhaust in the position shown in your diagram. No lambda sensor means no cat.
