And this is a good external sensor?

Here is a 3 bar pressure sensor (GM style), inexpensive and tested to work well with the LCDBC.

The GM 3 bar MAP sensor works great, been using one for years. Mine was a lot more expensive though.

That does vacuum too?

[Unlogic]

Yes it does.

Ordered thanks!!

Tip: the wire harness or pigtail connector is hard to insert on these Chinese GM 3 BAR pressure sensor. I found it easier to disassemble the harness and insert one pin at a time.

Wire color information:
Red=5V
Green=Signal
Yellow=Ground

Antero, thank you for the heads up. Also with your original power power plug, any reason installing some heat shrink tubing over the plastic wouldn't be adequate?

As long as you do a good job it should be fine.

(1) Now that I have a 1996 OBD2 ECU on my bench, I tweaked the speed about 20% faster by removing unnecessary delays the OBD2 protocol dictates but the 3/S ECU doesn't require. The Idle Switch request code is different on the 1996 ECU, this is fixed for 1996 DOHC ECU. I don't have the 1996 Turbo ECU ID yet, so those guys will have to suffer until I get the ECU ID from someone.
(2) Complete 3/S CEL table for OBD1 users (91-93), note the MUT Scantool only lists Active/Stored codes. Pending codes were not used in the MUT Scantool, so instead of deleting it, I left it alone.
(3) 94-95 USA CEL request codes were 100% incorrect, that is fixed. I believe 96+ Euro/Jap ECUs that don't use OBD2 codes will also benefit, as they probably just use the same 94-95 USA CEL request codes.
(4) Supports new coolant tables from MUTII scanner, go to config menu and select which coolant sensor your vehicle uses: (91-93), or (94-99).
(5) The rotary knob software routine was re-tweaked, so it is less sensitive to "bounce effect".
(6) Included additional diagnostic tests and fixed some errors.
(7) Uses new Barometer table in inHG or mmHG.

There could be other fixes that I don't recall at the moment. Still to do, use the new intake temp table, ABS functionality.
