So I'm having an issue with my car where the rev limit is lowered to around 5500 RPMs and fuel cut is around 6500 RPMs, the car is throwing an over retard code and a VVL code. The car is an 05 Elise with a Katana MP62 S/C and CharlieX tune. So far I have: disconnected the battery for about an hour (didn't fix it), checked all fuses with a multi meter (all were good), pulled the valve cover and inspected the cams (they look perfect), looked for blatant wiring issues (none), and had the ECU reset with a scan3 tool. The problem still persists despite all of this. I'm working with VSA Motorsports to try and get this sorted. They are thinking that it's either a wiring harness issue or a faulty intake VVT sprocket/gear (this thing: Toyota OEM Intake VVT Sprocket 1ZZ, 2ZZ - TOY-13050-22012 van Toyota OEM - Monkeywrench Racing -). Has anyone else experienced the same or similar issues, and what was the resolution? Thanks
