The headgasket we fitted is an earlier model gasket with more even coolant flow front to back to suit the re-route. It's quite dramatic to see how much flow Mazda stifled around cylinders 1 and 2 on the late model NB engines to force coolant to the back of the block/head.
re-route installed, ready to go
Most of the way there
Wiring went from this:
I've spent months and I'm back to where I started...
to this:
out of sight, out of mind
to this:
If I close my eyes and try, I can imagine this being a working car again
All the electrics work, lights, etc (hoorah!), and I can communicate with the ECU.
However I've run into an issue with the IQ3. I'm hopeful Magpie might be able to drop in and share some wisdom:
At first, I couldn't get it to talk to the PC through the serial>USB connection. Sorted out the driver and got it working or at least identifying an active COM port.
Now I can intermittently connect through the COM port to the dash and I've been able to reconfigure the display pages using the on-board sensors only. I can't get it to download the VNET sensors (including all the ECU sensors/inputs). It times out.
Occasionally I can't connect at all, sometimes it connects and starts working and makes it to 3 or 4 of the full suite before the connection fails due to timeout.
I know it was all working before - the same cable was used by greenmachine in his old race car so I'm assuming its something in the setup of the drivers/com ports on my end. I will keep messing around with it after work in the evenings but unfortunately the car is beyond wifi so it's a long process of test, fail, clamber out of car with laptop, run back into wifi range and search, test... repeat
