You need to put back the Lambda sensor & install race EPROM on the 312R.

Otherwice the engine will not run properly & not having all the extra power.

Remember that Powercomander only changes the fuel injection, not the ignition.

Please read the "Baffle Modification" thread for more info.

Best Regards,

312R Corse

If you remove the lambda then the std ecu will eventually log a fault and run without it. Long term this will make the lower rpm even worse than it already is.

To get round it you will need what is called a "race" ECU that will switch the lambda off. This then means that you can fit a PCIII to remap the fuelling which will go some way to helping things out but the bike will still have a number of issues with poor running below 5krpm.

There is another cure availabel from me in the shape of a fully programmable ECU that will properly fix all low rpm issues and boost all round performance everywhere.

Please don't take my (biased) words for it, do a search for Microtec or Microtek etc. I hope you will find all the information that you need.
