J am an owner of Renault Super 5 GTS 1.4 '88. J have reasons to presume, that the engine (C2JQ781) and ignition module (Renix RE-257)don't match: J observe loud work and overheating while using unleaded fuel (J presume that the former owner of my car replaced the original engine with other one).
If anyone has following data:
- which Renix module schould cooperate properly with my engine (type and description, if possible: advance angle etc.) ?
- description of RE-257 (advance angle etc.); does it allow to use unleaded fuel?
- does my engine allow to use unleaded fuel at all?
J would be very pleased

Regards,
Karol
