i have a k20 from an ep3 that i swapped into my elise s1 which has been running fine for around 3 months now, but as of two days ago, the car will not rev past 4k rpm. its as if it hits the static limiter. after a bit of searching i found most people were pointing towards: oil level, which is fine, the Vtec oil pressure sensor which i replaced today with no change or the VSS sensor which can come apart, i pulled this out of the gearbox and all looks good.
the car pulls hard right up to the 4k and runs totally fine otherwise. am i right in thinking my only other option here is to swap out the vtec solenoid? the car doesn't have an obd2 plug due to its age and i dont have the pins to wire one into my ecu ( i used a new e plug for the conversion harness so i cant cut and splice it in without them ), the ECU is also a k100 as opposed to a kpro so im unable to plug into it to get a read on anything there. so im running out of ideas here and i have a track day in a couple of weeks so really want to get this sorted asap.
thanks.
