Bipes settings help
 
hello,

I just wondered if there is a winter setting for the bipes, as it seems to come on boost really quickly between 3 and 4k rpm where WOT can not be used. Over 5k to the limiter its perfectly fine.

Just notice that it pulls around 6psi between 3 - 4k rpm, back off and hold it to about 5psi and its fine and continues to pull

I have changed plugs and leads and still no different

The current settings on my bipes is
Switch 1 = Open
Switch 2 = Closed
Switch 3 = Open
Switch 4 = Open
Switch 5 = Closed
Switch 6 = Open
Switch 7 = Closed
Switch 8 = Closed
Switch 9 = Open
Switch 10 = Open

So settings are

1.6
Full AFM Retard 5 degrees
1 Degree retard for each 20c or 30 degrees f
Start retard at 3000 full retard at 4000 rpm
Light on the unit displays Retard

The car is NA 1.6, with the begi s kit, stg1 intercooler, afpr and the bipes.

This has only started since the colder weather we are having in england, so didn't know whether I need to turn down the boost or change maps any help is appreciated

bipes controls timing, not boost

but there are various settings for the temperature for the bipes which I presume determines when the bipes retards the ignition, as the colder air is denser then in theory there is more boost being produced

what I don't understand is how the settings on the bipes work as you can start retarding the ignition earlier in the rev range, by getting it to come in earlier and possibly a temperature setting change may help in the colder months.

also what I don't understand is there doesn't appear to be a boost controller so I would expect it to be producing more boost but it doesn't ever go over 6psi, which leads me to think the bipes has something to do with it

I could have got the complete wrong end of the stick, but just trying to figure out what the problem is and it seems a little strange I get the problem when the bipes is set to retard at 3k and full retard is at 4k - the exact rev range I can't use full throttle
