Currently the LTT options in the new G5 flavour firmware is a bit binary..
 
Off, On, or Disable Input
 
I've been using the LTT Disable Input with a math block like IAT>50,ECT<80,Engine Runtime>60
the Disable Input covers both updates and application - with it disabled, the LTT doesn't apply trim but doesn't update the table either.
 
I'd like to get the best of both worlds... I'd like a feature to have LTT updates disabled but the trim constantly applied - my intuition (system sperg intuition) tells me that combined with general CLL this would give a better effect.
 
In other words, I think I could trust the LTT to give better general results in most conditions especially when the table is filled out, but I'd rather not have it constantly updating the table when outside of normal running conditions. I.e. Hot restart or stop start traffic or similar edge-cases.

This is Scooter, my 1999 NB Miata. Acquired in August 2017 as an OEM+ car that became an ITB learning project. Quad throttled since 2021 and used an MS3Pro for a while before making the leap to a Link G4X. I'm very grateful to KORacing for getting me up and running and answering all my questions. This is the best the car has felt in years.
The G4X ECU is setup to run modelled mode with MAP as the Load source and TPS on the Fuel, Ignition and Target tables. The MAP is jumpy but the car runs great. There are fuel pressure, oil pressure and oil temperature inputs with safeties looking after the engine. I've also played with Math channels, virtual outputs and CAN Auxes to setup custom functions such as virtual fuel tank resets, flood clear, knock CEL and an extra idle up when the second fan turns on. Some virtual outputs also feed the GP RPM Limits for AFR and Fuel Pressure safety. I've also played with Launch control and gear shift control. Both worked really well but mechanical sympathy doesn't let me use them often.
The engine runs sequential ignition with Toyota COPs and sequential injection with DW 550cc injectors. KORacing setup the injector deadtimes for me because the data I got from DW was far from correct. I intend to setup a Flex Fuel sensor and run modelled multi-fuel for the new-to-me VVT engine build.
The goal of Scooter is to be a fun fizzy street car with track capability. It competes in ABQ Super Lap once a month, and we will soon make the trek to Colorado for trackday at Grand Junction Motor Speedway during the Flyin' Miata Summer Camp. I'm excited to be part of the Link community and continue learning with this car and ECU.
Stockish power, 2250Lbs, 7500RPMs. Snorts for days.

Unfortunately the adapter board on this ecu is quite old and doesnt have the knock input available on any user-accessible external pin.  If you wanted to return it to our UK office they could add a couple of wire links to make the knock input available.  

Recently fitted a Link G4x PNP v3.1 to my 1993 Roadster with Toyota ae101 ITB's everythings going great so far and really happy with the software, the car runs well, really well infact and drives like an oem car for the most part which is says a lot about how good this ecu and the software is!
Now I'm road tuning at the moment, VE tables coming along and I've now enabled CLL. Currently have a reasonably conservative ignition table in for the moment, whilst I know roughly what numbers it should have (and I plan to get it dyno tuned at some point too) it would be nice to add knock control for peace of mind.
I've wired my Toyota TPS and LSU4.9 Lambda sensor up via the G4x expansion ports which work perfectly, thought I might be able to do the same with a knock sensor but can't see a way of selecting an input for it within the software if I do. Is this something that could be fixed with an update to the pclink software or is it a hardware limitation here?

If its not possible I guess theres the knocklight that would give me some form of feedback, but would be nice to have trims.
