D'oh! That's what I get for skimming posts at work! That should be at the top, not the last line. It's the only important part. 
By "The LH2.2 SharkTuner will also tune Euro 16v cars, MY85/86." I would assume he means 84-86.

Matt,
According to JS, the 84 Euro brain is unique. You can change to 85/86 Euro brains and then SharkTune. AFAIK, you might be able to use US brains too?
The 85-86 US clone chips I have had near perfect fueling up top with the no cat X-pipe I have, but could stand some tuning at the low to mid range. The EZF tuner will probably give the most gains.
A separate knock sensor box would be awesome. Attach the output of that to an EZF input, like the octane loop, or switchable maps by use of a EPROM adapter board.

The 84 controller may be able to be upgraded to 85/86 spec, but that is not something I have addressed yet. It depends on market demand.
You can of course fit an Euro 85/86 LH in an 84 Euro with no car wiring harness changes. That is the simplest way to go at present.
Thanks everyone for your positive responses

M28.21/22
LH = 928 618 123 02
EZF = 928 618 124 03 (except M154 which uses the 04 version)
...at least that's what PDF PET on Porsche's website says.

The difference between the 84 and 85-86 S2 brains is a John question, as I don't know what those differences are.

So if I read correctly, if I already have a DR "Mountain Man Xpipe" with cat delete and Auto Authority chips the only gain would be in "driveability" & perhaps a little on the top end?

When I was looking for a spare brain (I obviously need a few for reading today) the one listed in PET5 I have at home was the same as the stock original part. Both 84 Euro LHs I have are the same part number. The spare is the same as the LH in the 84 Euro of the person I bought it from. Since they are supposed to be extremely reliable, I doubt all three had been replaced.

To make it simple and not hijack John's thread about his wonderful product any farther, lets' say if you have an "928 618 123 02" LH computer then his SharkTuner should work, and if you have an "928 618 123 00" as specified by Porsche for MY 84..... John says it will not work.

All the first year computers are functioning prototypes? The L-Jet '80 is a different number, but the '81-'84 boxes drop in, and work fine. The '87 S4 brain does not have functioning diagnostics (but can be upgraded), like the '88-. The '84 Euro falls in this category.
Of course, the '86.5 LH2.2 is the best of the lot, and makes the most power!

I need a boost method for my '86, in order to expound on my theories! Purely for science, of course.

Sorry Dave and John, I was thinking of the WSM page Dave posted. PET5 says the same as PET6.
Porken, with the limited space, I would think you'd have trouble adding maps. Maybe replace the WOT map with a 'on boost' map?

The stock LH2.2 (and EZF) uses a 2732 chip, with 4K. JS uses an adapter board to use the more readily available 27256 chip, with 32K, but only using one of eight blocks of 4K. I understand that the lastest revision does have an option to make 2732A chips, if you can get them.
It is possible to wire the adapter board to switch which block the chip outputs when queried for an address value. So you could theoretically have eight different map sets. I don't know if you can switch while running, though.
JS has hinted that he is leaving it up to others to exploit this collateral feature.
