Boost OS V4.5 - Bug Fix

Narrowband O2 Sensor Bug - Causes O2 trims to not update, which could cause a lean or rich condition that will max out the short and long term trims.

This bug only impacts users that have the narrowband closed loop enabled.

It is fixed in the attached V4.5 patch. No need to update if you are not using the narrowband O2 sensors.

Discord Server Created

I've created a discord to try and help communicate with everyone. I hope this will not only help me keep in touch with every, but also allow everyone to discuss amongst themselves. Follow this link to connect your Discord account to your Patreon account.

Version 5 Feature Requests

Starting to think about putting together ideas for V5. I have some features that I want to add, but I'm open to adding to the list. Also if you would like to see one of the current features improved please comment about that too.

Here is my current list:

• MAP based spark tables (2 & 4 Bar) - High Octane Table, Low Octane Table, Coolant Spark Table, IAT Spark Table, Flex Spark Table
• Update EGR Position with Boost Control Duty Cycle when EGR is dis...

Issue Track Testing Wideband Closed Loop

Edit 2: I tested the fix and was able to confirm that both issues are fixed. I've uploaded a new version of the Boost OS Patcher (V1.4) that will allow you to upgrade to BOS V4.4 that includes the fixes.

Edit: I believe I found the bugs and hope to get the fix tested soon for both issues.

It looks like I’ve found another bug with logging the EGR (wideband), but It’s a simple fix. I also had an issue testing the wideband closed loop at wide open throttle. I’m not sure the sou...

Interested in Nitrous Features?

I know I called it Boost OS, but there is nothing wrong with a little laughing gas. I haven’t used it before, but I would like to hear if anyone would be interested in some features to help tune for or even control a nitrous system.

If you have an idea of what would need to be added or a product that the ECU feature could replace let me know in the comments below.

If there are enough people interested I could look at including some kind of control in a future update.

Thank...

LS1 Boost OS V3 & V4 Overview

I put this video together to help go over the patching process as well as give a brief description of each of the features and how I intended for them to be used.

I hope this helps as I've have a few questions on a couple of the features and I'm sure there are more people that haven't reached out that this will help clarify some things.

Thanks,

Branden

5 Years Ago Today

It’s been 5 years since I first built my bench top PCM for testing. I’ve come a long way in understanding and writing code. I’m sure I have a lot more to learn, but I’ve accomplished more than I thought I would be able to without having any schooling in programming. I still have more ideas that I want to implement in the P59 PCM and other platforms that I want to learn about and create new features for.

I appreciate all the support from everyone! And I can’t wait to see what I...

V3.3 - Bin & XDF Bugs Fixed

Attached is the bin already patched and XDF with bug patch to resolve a few bugs I found while testing.

I took some extra time to verify each feature was working as intended which took quite some time, but I did find a couple bugs because of it so I hope you all should have a very good working operating system to use.

Let me know if there are any other issues, but there shouldn't be.

Bug Alert - Overly rich and inconsistent fueling

Version 3.2 has a bug that when running a 1 or 2 Bar VE table the fueling will be rich and inconsistent causing a very difficult time tuning. I believe I have a fix coded up and one person has confirmed that it fixes the issue. I would like to take another day to verify it is fixed before releasing it.

I will be releasing a V3.3 bin and XDF with a patch to resolve this bug as soon as my testing is completed in the next day or two.

Thanks everyone!

V3.2 Bug Fix - 2 Bar VE Table

Looks like I found a bug in the code that selects the table for the 2 Bar VE table and it will always use the 4 Bar VE table in the event that  1 or 2 is selected for the Boost Table Enable.

I've added a simple patch in the XDF attached to fix this bug and updated the BIN file for any new users.

Sorry for the inconvenience and please feel free to send me a message if you see any issues.

Thanks everyone!

Version 3.1 - *XDF Update*

Ok, so I forgot to add a table to the XDF that allows you to edit the Wideband Ready Voltage for the closed loop fueling code.

Attached is the updated XDF with that table added in the Closed Loop Fueling folder. The values will likely need updated for anyone that is using or wants to use the closed loop fueling feature. 

My wideband uses these values:

• Min: 0.5 Volts
• Max: 4.5 Volts

I meant to put those values into the bin file, but incorrectly ...

Version 4 Progress Update

So I'm getting pretty far along with the next version of the OS. I haven't done any testing yet, so there are probably some bugs that I will need to go back in and fix, but at least most of the code is implemented.

Here are the new features in Version 4:

• Gen 4 MAF Calibration Table
• Over Boost Spark Cut
• Wideband Ready Test
• Wideband Scaling
• Launch Control Soft Limiter
• Engine Speed Soft Limiter

All the new code still need...

Analog Input Reverse Engineering Video

Did a quick video talking through how a raw analog input can be found. If you have any more video ideas for reverse engineering be sure to comment down below as this is something I enjoy making and it's nice to help out beginners as I wasn't able to find anything like this when I started.

V4.0 Feature Ideas???

I've started to think about the features I'm going to add for the next version of the custom operating system. If you had any ideas please leave them below and I'll use them to help decide what new features go into Version 4.0

Things I'm thinking about adding:

1. Gen 4 MAF Table

2. Soft limiter for Launch Control & Limiter (Spark Retard)

3. MAP based spark tables

4. Over-boost spark cut

I don't have a specific timeline for releasing this, but I would li...
