Technical Punto GT Ecu Help

[Makot1212]

Hi all, I have recently came into possession of a 1988 Fiat uno which i bought from a customer as the CVT gearbox belt had snapped, and pump shaft twisted. Unfortunately as much as I tried to save the cars originality and rareness as it only has 20k miles, i could not find any parts to fix the gearbox. I'm by no means a Fiat fanatic however i love the idea of owning a Fiat uno turbo. Since then i have also acquired a Punto gt3 engine, gearbox and loom and my plan is to build a somewhat sleeper uno. Im no stranger to engine swaps, wiring or tuning as i do work for a performance vehicle workshop. Long story short I have taken the cover off the original punto gt ECU and have found a SEB2 GT3 chip inside along with 3 red wires going to the map sensor, I was wondering if anyone has any insight into what the 3 wires on the internal map sensor might be for? unfortunately im more use to the modern file, read, edit and write over OBD of ecu tuning and have never seen anything like this before

I'm not much help to you on this but having been around here for so long I know SEB chips were really common on PGTs back in the day, there was a 1, 2 & 3 chip based on what else you had..

They were sold by an Italian company called 'Power On The Road'. I should imagine they either don't exist or are known by something else by now, but there will no doubt be some old threads on here about them you can read through. Or try Puntosports forum, it disappeared for year but i think its back up, i'd assume all the old stuff is still on there.
