Bill-
That's great! Back in post 242 I threatened to send MK some PEMs and my WBO2 and ST2 if he'd frickin' ST his car and post the datalogs of him ontrack. The PEM's are in the mail to me as of today, so I guess the only remaining questions are:
A) Does he have an accessible bung to install the sensor?
B) What year/flavor LH brain does he have? IIRC the '87 brain won't work for Sharktuning with PEMs in it (?)
EDIT: Nevermind part B), brainfahrt.

Is there a part number on the LH unit that below that number wont work?
I ask because I have a 87 that I am getting ready to tune, but I have a few other LH units.

For some reason I have in the back of my mind that I've been corrected by John Speake on this point in the past- haven't found the thread yet, but will keep looking. Would be happy to be wrong.
EDIT: Duh, I'm thinking of diagnostics using a Spanner. Nevermind.....

edit: Turns out AO's problem was a loose diagnostic connector.. I found the references in the ST2 thread, post 190-ish onwards
This reminds me, I need to buy a spare EZ-K to keep my PEM in.. swapping brains is much easier than swapping PEMS in and out.

I thought there was an early EZ-K part number that had problems talking to the sharktuner, found only in the very early part of 87MY. From memory Andrew Olson had the issue and posted a thread about it here.

Good to see you posting again DR !
87 LH is SharkTuner PEM compatable.... you are confusing with the fact that MY87 don't have the diagnostic version of the stock EPROM. You may remember that a change of EPROM to MY88 will give you diagnostics with that EPROM.
Yes, the very early 87 EZK have a filter board near the 35 way connector that prevents the PEM fitting. A simple notch is all that's required. This mod is described with pics in the User Manual for the PEMs and also in the ST2 User Manual. At some time I believe that Mark's EZK was changed from a hacked up development unit used for the Bonneville record runs to another "Proper" EZK. So his EZK could be the later type.

Well, his racecar is now 'just' a production '87 model, so the PEMs had better fit. 
This package arrived today, Kibort- where do you want 'em sent? Let's coordinate with Bill B. to see what I actually need to send you..

John-
The PEMs are part an offer to MK to be able to do some datalogging on his car at speed, on track. Benefit to him is that he actually gets a proper tune on an engine that might gain him some power, and the benefit to us is we get to see some datalogs on rpm, time at WOT, injector duty cycles, etc from a stroker motor being used on track. No such thing as too much data, said the scientist...
All that said, I'm guilty of some thread creep, sorry.
On topic: I averaged 17.86 mpg on the trip to SITP and back. Before that, I was getting around 12 mpg. So we can add improved fuel economy to the list of benefits one gets from dry-sumping one's heads.

Not saying it wont help, but it wont help that much.
Still 17.8 is a impressive number for a 6.4L.
What rear end gear do you have?

i got 22mpg on the way to thunderhill. trying to go just 70mph, but that was impossible. the car is too much fun. anyway, i wonder what 65mph, controlled would give me on hyway 5.!!

A totally tongue-in-cheek, useless mileage comparison. The 12 mpg is mostly 'round town, between insufferable numbers of poorly timed traffic lights in Orange county, mixed with sticking my foot in it a lot.
Most of that 17.8 mpg was loafing along at 2700-2800 rpm in 5th gear at 70-75 mph, the ST2 says I'm at 7% duty cycle on 30 lb injectors at that pace on level ground. I have the standard 2.2727272 rear end.

does this change the tune it has today? or is this just a metering tool for monitoring and then later tune?
If bill knows what to do, and its not going to effect performance at the track, and cant hurt anything, im game!
did we find a bum cable from 928intl so I can splice it into the open leads coming off the wiring harness. should be covered by 928 intl warrenty as the original cable was missing this part.

Forgive me if this insults your intelligence, but the PEMs swap into the LH and EZK brains, you load a 'base' map into each one, then you go out and drive the **** out of the car with a WBO2, laptop and ST2 connected. Data gets logged, then the data files get plugged into Jim's sharkplotter, which adjusts the fuel and timing maps. The adjusted maps get ported to the PEMs, then you repeat the cycle. What size injectors do you have in that motor?
Bill knows how to do all of this. All you gotta do is drive.
No leads on a cable yet but in post 301 Bill says that's a non-issue.
It's going to improve your performance at the track. That's the whole idea.

What can be used, done to a 16v motor to help with the oil in the heads problem?
It seems the system is for 4v heads, engines.
Any love for 16v engines?
Starting to think its time to drop a 5.0L 4v in the OB.
