I've just bought a Bazzaz Z-Fi with their Z-AFM module to get my bike mapped for an open-ish airbox mod (MWR filter and power up kit)... after doing a little bit more research I read that the stock ECU on my '13 M796 has a closed loop which governs the lower part of the rev range that the O2 sensors normally get involved with (I've removed mine). Is this the case? And if so, is there a cheap / easy option to remove this closed loop? I know that flashing the ECU with the DP map will solve the problem but spending out a couple hundred quid on that as well as all the Bazzaz bits isn't ideal! I'd just really love to clean up the lumpy surging I get for town driving with a full remap.
The Bazzaz Z-Fi is £250 and the Z-AFM is £200 ... this does the remap part (Z-Fi comes with a slip-on map which would be similar to the DP map, the Z-AFM builds a custom map based on air / fuel mixture in the exhaust). But - from my understanding it can't give a full map without flashing the standard ECU to the DP version or similar to remove the closed-loop part. This is what I need confirmed really, and to know if there's a cheap-ish way around this as the map that gets flashed on to the ECU isn't even relevant as long as it removes that closed loop.
Did the Z-Afm come with 2 sensors ? I was looking at the PC5 when I nearly bought a Monster and they had all sorts of wizardry going on with O2 optimisers and certain areas of maps that have to be left alone etc. Even to the point that with their Autotune the O2 sensors need to be left in.... Sadly looks like the flash is the easier/better option Email them and see what they have to say
Remap with a Rexxer map removes/deletes the O2 sensors and exhaust valve. No need for anything else and works a treat. £230 job done.
