I registered this forum ~ a week ago, and it is time to intoduce myself and my 106. Well I am a 50+ years old electrical engineer. My first own car was a 309Gl with 1.1 engine. I purchased that at 1994 in Genoa Italy where I stayed one year. A few years later it was stolen... Than when my second daughter was born we needed a car, so I purchased a 10 years old 205 1.9 GTI. A real family car...
Later I used company cars, I sold the GTI. That was a rational but probably a bad decision.
10 years ago I found an ad someone was selling a 106 S1 Rallye for ~300Eur. I purchased it for amateur racing purposes. All the internal parts were already removed, and it was already withdrawn from circulation. I gave it to a Peugeot specialist mechanic asking him to prepare for race at the lowest possible budget. The engine was checked, timing belt was replaced and the rear suspenson needle bearings were replaced. Nothing for beauty only for safety. As driver seat was already remobved by the previous owner, I put a 106 seat from a 1.1 model. I went for some slalom race with this "setup". The racing seat, quick rack, better shock absorbers were missing. And the car was not as strong as I expected but without the possibility to compare it with an other 106 Rallye it was just a feeling. Below 5000 rpm it was really weak. Later I spent some time to check the engine. I read the error code and there were two errors: knocking sensor and lambda sensor. I spent about 2 hours to find where the knocking sensor is located when I realized it is missing. So I purchased and installed one. I tried the car, but I felt not much changes. During a race the exhaust pipe was broken, and I took it to the service and I asked to install a second lambda connection nut also. I installed a wide band lambda sensor, and logged it's output. I take a few laps on a small track, and I realised that the lambda is ~0.7-0.8. It means too much fuel, and al lower rpm the engine was almost suffocated into gasoline. The ECU was tuned by a chip, but not properly...
At first I selected a "hardware" soluion instead of "software": I mixed the gasoline with ethanol. I set the lambda level to ~0.9, and the engine started to live. Later I managed to download the original eprom contents of the 106 Rallye ECU, and I flashed it to a new eprom. So I "downgraded" the motor to factory level.
I added two pictures from 2016-17, and other two showing the actual condition
