Logging setup for ECU logging

[sportbikeryder]

Does a G4+ ecu need to be connected in order to configure the ECU logging selections in PC Link?

 

I have been evaluating the G4+ software as a potential candidate for a Turbocharged motorcycle for drag racing. When I attempt to add a parameter to log in teh ECU based configuration, an error message states the number of channels has been exceeded.

Hi John,

Yes, that is correct, an ECU needs to be connected to configure the on-board logging. 

The reason for this is that a G4+ ECU can have different amounts of on board logging channels. For example, the G4+ Xtreme as it ships comes with 15 channels, but you can perform a feature unlock and have 25 channels.

Without being connected to the ECU PCLink does not know how many channels the ECU is capable of.

Without having an ECU connected you can still see all the possible parameters and statuses that can be logged. If there is something particular you want to know let us know.

What is the channel limit on a Thunder?

All of the G4+ range with current firmware can log 100 channels to internal memory.  Logging frequency is independently assignable for each channel, max 100Hz.  The memory size is the same 4MB on all G4+ ecu’s.

Do you have a typical log of a good running that I can look at?

I can probably find you something when I’m back at work in about a week. Overseas on holiday at present.  There are a couple of example log files installed when you install PC Link but they are many years old (from G4 days from memory) so they probably aren’t great examples of what is possible today.

Do you run the ITB motor in your pic?  They tend to be very interesting.

Yes, that was one of the first Efi engines I done about 20 years ago when I was a teenager.  Motec M48. Couldn’t get many SR20 parts in those days so had to make throttle bodies, camshafts, dry sump system etc from scratch.  Datsun 510 rally car.
