If you couldn’t find tuners who tune on MHD then you should have just gone with Ecutek. The best thing to do is select a tuner who you like and go with the platform they prefer.
They are definitely still releasing it. Last time I talked to them they said that they are waiting with the release until they have the same features for the S58. So at the moment there is no ETA.
The mold turned out great! We should be starting production very shortly.
Note that in the photo these are still raw plastic from injection, after painting they will look even better!
