Hi everyone,

I recently swapped the old 1.1 engine in my Peugeot 106 Quiksilver for a 1.6 16v TU5JP4 from a Peugeot 307. This setup includes the drive-by-wire throttle body and the Bosch ME7.4.4 ECU (similar to the setup in a Peugeot 206 1.6 16v, if I'm not mistaken).

To enhance performance, I’ve also fitted the following:
Cams from a Saxo VTS (TU5J4)
4-1 headers
63 mm exhaust
Standard performance intake

The engine overall responds well, but I’m experiencing an issue with the idle. It’s slightly erratic—the engine almost stalls, then recovers repeatedly in a cycle. My guess is that the mixture is running rich, and the ECU is struggling to correct it.
Has anyone here done a similar swap and encountered the same idle issue?

If anyone has a tuning map for the Bosch ME7.4.4 that would work with this setup, I’d really appreciate it if you could share it.
Thanks in advance!
