  1. That's some good feedback. As you pointed out, there are quite a few assumptions and pit falls when it comes to this. However, many will also apply to manually dialing in injectors with a wideband. So I don't necessarily see them as issues directly preventing an automation of the process - but that doesn't mean we should ignore them! Differentiating speed density errors from injector scaling errors is an interesting point and I'll admit, something I've only considered from a theoretical standpoint. I would like to break it down to its simplest concept - there can be errors in lambda

  2. Hi Everyone, I'm a data scientist by trade and have been considering throwing together a script that could aid in dialing in injector slopes, breakpoint and deadtime. The input would be a reasonable size datalog of AFR, injector pulse widths and such. Using some non-linear optimization, it should be possible to identify what variables need to be changed to minimize lambda errors. It should be possible to differentiate speed density errors from injector scaling errors, as the lambda errors will track with injector pulse width. I've only just got my wideband sensor wor

  4. Problem: You have 2 fuel pumps for your large power goal which causes high pressure fuel spikes at low load/idle due to over supply. Problem 2: You want to control a water meth injection system based off rpm / load however traditional window switches cannot easily access load/map pressure. Solution: Utilise our custom operating system IMRC/IMCC output re-configuration which allows the IMRC/IMCC output to be used as an external trigger based off an RPM window and a Load (MAP Pressure) setpoint. As the turbo vehicles do not use the IMRC runners this output driver exists on the PCM and
