Sharktuner Incompatability..and what is this chip?
Tried to use a ST this weekend, and for a time, we thought that we fried the brain, because we got the sick sound of fule pump & injectors going nuts when we turned on the key.
What we think..is that the ECU repair seen in these photos, is not compat with the SharkTuner, and going back to the chips that were in the cases to begin with, got everything back to normal.
Also..any idea what this chip is in my hand in the other photo?

If the car starts correcly with the stock EPROM fiited in place of the PEM then your LH doesn't have basic tile failure.
That replacement tile shown in your picture should be OK with the SharkTuner as far as I know. It was the tile replacement from Electronkrepair that was not.
Make sure the PEM is plugged in corectly, with pins correctly aligned. Then set up the ST and File>New and load an LH fuel map. Then you should be good !

You're using an Sharktuner Mk2 I assume ? There may be a K line data communication problem with that replacement tile... I don't have experience with that type. If possible borrow another LH to eliminate that posibility.

Thanks for the offer, but I have seen these several before. Shouldn't be a problem to use with ST2 AFAIK.
PEMs are now preloaded and labelled with LH and EZK files in pairs and are ready to go. Your PEM is an early one not showing LH or EZK preload on the label. In that case it would have been tested wih a preloaded LH file before dispatch . So without connecting the ST the car should have fired straight up. Of course now the data is obviously corrupted due to the unsuccessful load.
You shoiuld be using the latest software Ver. 6.0.13 with the ST2.

John, I'm curious.
WTF is that puddle of white stuff on the replacement board? It's obviously intended to be there and has solidified. What's it for? Heat dissipation?

Since these PEMs were not labelled, I tried to load a stock LH BIN file, but it would not load. Had a lot of communication issues. The PEMs were properly installed.
This is ST2, so is there anything we can do for the K line problem besides swap brains? We will use my LH if not.

If you can, try Jeff's LH in your car (with PEM installed) and see if it loads. If that works, move it back to Jeff's car and then load ST from PEM's, save the LH file, and then try opening and loading that file. If that works in your car but not his, then it is a problem with the bus wiring I think.
Alternately: Jeff, you can also send your LH & PEM here and I will try it in our '88, see if it works. UPS ground is 2 days, so to get it back by Friday will require overnight one direction.
Either way, that will isolate whether the problem is with the LH, or the car.

So far, my experience is that the STer II only works with factory brains or John's rebuilds. Annoying, but that's what I've found. Also, be sure to check the diagnostic port. Had one car where the wire had been repositioned. That was fun.

PM me an address, and if that works out, they'll be off.

It's an epoxy to keep their circuits secret. I think it would reduce heat dissipation rather than exhance it. I have had several failures of this type in here to rebuild.
I've just found an old LH here with that version of tile here, just tried it with an ST2 and it loads the bin file fine. So in this instance the tile has partially failed in some way, or there's a car wiring problem, as AO suggests.

The ST2 has no problem driving the K data line in the car, no additional resistors as was required with ST1 and PEMs.
Use software Ver 6.0.13 to have all latest features.
I have just tested an LH like Jim's with a PEM and it loads a bin fine from an
ST2 with no problem.
