hi scoobynet guys and gals, on giving the car a fairly hard blast in 1st and 2nd when the revs reached approx 7000 rpms the engine check light flashed then I moved to 2nd again at same revs light flashed up, is this knock detection? or gear shift light doing its job? car mapped by BR and using v power only alcatek ecu.

 

Knock detection.

 

Could be either shift light or knock detection. Depends on how the ecu has been set

 

as above speak to your mapper and find what it was set for.

 

mab a code reader might shed some light on it. car was mapped on road holding it in 4th gear at 1.5 bar as I remember, has 2 maps , alc and lc . engine seemed happy enough after no noises revs holding steady at 750. thanks for above responce

 

A code reader wont work with this ecu. Need the correct software

 

mine flashed for rev limit and solid for knock rev limit(may have been the other way round)
pretty sure your just hitting your rev limit light.

 

indeed , the revs went up to 7000 bit quicker than I thought they would! did an oil change using mobile 3000 fully synthetic that afternoon, I swear its given the engine more go ...... placebo effect im not sure? but sure feels quicker than before. thanks jay and chaps for the above info.
