  1. 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

  2. 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

  3. Honestly it all sounds great and I think if you can put the time in it would work. I'd be happy to ask some tuners who might be willing to collect some data for you if you are serious. The only concern is this sounds like a year long PHD project. Do you actually have the time to do this? If you do we will do our best to support you as there are many other applications I can think of that might have a business case behind them if it can be done in a short time period.

  4. These forums is a good place to start. You need to start threads with pointed questions for a very specific task showing what you have tried, your results, what you expected vs what you got and what you are stuck on. Your question above is far too general for anyone to offer any assistance. If you truly do want someone to help you with all of the tasks, eg proper paid tuning training then this is something that various companies can offer however there are a few requirements. Wideband, knock ears, fuel pressure monitoring equipment and a dyno. Do you have access to all of the above? If so

  6. 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

  7. 1.25 has been released and is a maintenance release. These fixes improvements are all in the backend to help us diagnose crashes/bugs and to resolve some specific user experience issues in the custom os wizard Improved error handling that allows some errors to be "ignored" so you can save your data instead of closing the editor. Resolve a freeze in the custom operating system conversion wizard under specific use cases. Disabled the "previous" button in the custom operating system wizard as this could cause customers to reset all their tables without their knowledge. User
