Aftermarket ECU options

I am interested in an aftermarket ECU that will either work with or entirely replace the Tacoma OEM ECU. The main reason for it is that I would like to have access to the history of engine operation, not just engine codes via OBDII when the check engine light is on but actually a lot more detail such as all the readings reported by all engine sensors, actuator engagements, even throttle control history and the timeline of gear shifts.

Before you start asking why I need all this (you may skip this paragraph if you understand the need), I will make a comparison of what I am trying to have access to to what I use in my day job as a software engineer: log files. A log file, to all of you unfamiliar, holds a history of an application's runtime (and a vehicle is an application, mechanical, not software) to which entries are written by the program that they log. So when a user performs an action, the programmer might want to specify an instruction to log that action in the log file. The better (more but not too detailed) log file will provide such account of operation that the reader should be able to reconstruct the timeline of user actions from the user's perspective.

I would like to read the data from the ECU via its built-in Bluetooth and a smartphone application in which I can view the diagnostics. It would also be cool to be able to monitor the activity at runtime as the truck is being driven, e.g. what reading the emission sensors are getting, when the VVT kicks in, AFR etc. All kinds of good data that go into the ECU but, as of now, stay trap inside without giving me access.

I have heard of Haltech but am looking for more recommendations. I think Haltech requires a laptop and USB, which in this day and age seem like an outdated way of synchronizing data.

 

Wow !! Sweet

 

I wonder if their data logger would suffice vs. an entire ECU swap out?

The Toyota techstream program does all that already. It's the same program the dealers use. Only thing it is hardwire. You would never be able chapter all that info reliably via Bt. Copper is king transferring data.

Just remember, every parameter you want to log is gonna slow up your computer. You will need lots of computer horse power.
