The serial version does work as long as you have the correct cable, and it does itís job.
I actually sold my old one on this forum classifieds. And the buyer used it successfully, found a cable that he purchased (you do have to get a compatible cable, was a discussion on the forum about the cable at the time I sold it) and I believe he used map(s) from members of this forum.
It can save a bunch of money, maybe just a bit more hassle to deal with.
I think I sold mine for $50, cable was probably around $20 and of course the pre-existing maps were free.
The map formats are different though, so you canít directly use PC-USB maps with the serial version.
Although, and I may be wrong, I think you technically can screen shot a USB map and then hand key all of the values into the serial software. Just more work than plug, download, and go.
I just chose to go the other route for ease of use and tuning. I will say that the throttle response was much smoother.
Whether it is worth the cost of the PCIII and tune is probably matter of personal opinion.
The old format was in .map
The USB version is in .djm format.
There is a decent inventory of good maps in both formats.
Agreed, and for some riders the price difference between the old serial port version and the newer ones, could easily make the difference re affordability.
There is nothing wrong with that at all.
And the serial port version works well.
One can use the software to morph a .map format map into .djm, but the reverse does not hold true.
To create a .map format map for a serial port version, one needs the serial port era software package, which is no longer a download from the Dynojet website.
BUT Dynojet will issue it via a customer service request. (at least they did up to about a year or so ago)
Once you have the software, one simply starts with a blank map and keys in the same values as appear in a .djm map.
