I faced the same problem with a fuel injected motorcycle engine. The old computer required DOS5.0!!! Went to Microsquirt and the transition was quite straight forward. I have been racing with the system for 3 years since.

I use Dyna 2000 with microsquirt V3 with no problems, fuel only.
Use yellow tach wire (5V square wave) to pin 30, and pin 31 to earth. Ignition settings - Rising edge, Trigger rise, Trigger wheel teeth = 0. That should cover it.

Yes, use yellow tach wire. Ignition settings - Rising edge, Trigger rise, Trigger wheel teeth = 0. That should cover it.

Are you using Dyna S or Dyna 2000. I run fuel only and let the Dyna 2000 programmable look after spark. The Dyna 2000 has a tach wire that inputs into the microsquirt. With the Dyna S you would have to condition a tach signal from the coils as per the guide. The microsquirt cannot run the Dyna coils ...

Now I am ticked off. It appears that something has has gone wrong as the Microsquirt no longer reads AFR from my Techedge WB. Reads a constant 19:1, even when shorting the O2 wire to ground. No wiring issues. Tried many reflashes with no luck. No obvious damage or shorts on the board. It worked ...

RT's response was to give me new firmware that they were adamant would work with the serial adaptor. It took a while for me to try the ECU adaptor on the Microsquirt with the new firmware from RT. The end result was a corruption of the Microsquirt firmware, requiring a complete reload. Fortunately ...

Thanks Mike,

I am eventually going turbo with these ITB's, so it may be opportune then to upgrade to the MS2Extra code. How hard can it be to transfer a working setup from 3.830 to MS2Extra 3.3.1?

The RT CAN adaptor costs as much as the ECU adaptor, and can't see a point if there is a high chance ...

Feedback from RT is that I would have to run MS2/Extra code for their adaptor to work (if that is indeed the case), so I am none the wiser. Maybe future B&G code for the uS V3 could have the same serial code embedded so that these comms systems are standardised? At the moment it looks like I am ...

So, to clarify, I have a uS V3 that I want to use with the DL1. I am using the original code, and not using Extra code. Hope that helps someone chime in.

I purchased a serial ECU/DL1 logger adaptor from Race Technology to suit the MS3, but the EFI will not run with the adaptor connected (no prime pump, no start). Disconnecting the adaptor allows the engine to start and run normally.
They state on their website that . . . "The Megasquirt MS2 serial ...
