I am driving a Wira 1.8EXi which is using 4G93 DOHC engine. Below are my upgrades to engine bay so far :
1. Center cat 2.3" and piping 2.3" straight through till back cat back
2. HKS Powerflow 200mm Air filter
3. Throttle body upgraded to MIVEC's which I think is over 60mm (anyone got any idea?)
4. NGK spark plug cables
Basically not much but I m thinking of getting it tuned as I left it unused for a few years and I find the engine not as powerful as it used to be. Am thinking of getting a piggyback for the ECU due to financial constraint. What sort of piggyback or electronics should I get? Last time might be a SAFC II or eManage. Any advices? I am hoping for a second hand piggyback if available.
