So I bought an 86 Turbo Z T2 conv. Runs 4 wire AIS to my knowledge. But still has LM Map sensor.

The guy I bought it from mentioned he got it from Turbos Unleashed. The car runs great with it in it other than what feels like a cut out at around 3000 RPM in every gear but I think that could be a fuel problem or TPS problem.

It looks like it is an 86 omni LM housing or at least that is what this states.
The Chip inside has 05233077 on it (non socketed id assume) and it looks like the MAP sensor connectors have been soldered in or are those stock locations? Map sensor wires are Red wire off connector to pin 24 or 25, White wired to pin 19 on the blue pinout which is Map Signal and Black Wire to GND on the board.

Just want to make sure it can be socketed with an upgraded T2 Cal, I want to run 3 bar Map and +20's or +40's and about 18-20 lbs boost.

Can anyone close to me Socket it and Cal it?

I live in SImcoe, ON, Canada.

Thanks for any help guys.

looks like an 87 computer with the 86 style internal map sensor wiring soldered to the external map pins. not sure though as the red and blue connectors would need to be re-pinned from 86 to 87 spec for this to work. plus I didnt look up any of those part numbers.

confirmed..... 5233077 is for an 87 shelbyZ stock ecu. so whoever did this added the map inside the case rather than change wiring and vacuum lines. not a bad idea for ease of install but then you keep the potential vacuum line freeze issue. make sure the line is clear. :)
