Got my car mapped on sunday at rcm on way home at 6,000 rpm check engine light flashed on and off,same tonight .Any ideas?

not used MOTEC personally, but pretty sure it is the same as the GEMS.............................

it will be using the CEL light as a 'shift' point and probably whoever 'mapped' your car has forgotten to set it more appropiately??

I am dropping it down to rcm on saturday to check it out.Bob mapped it
marty

 

Not to worry you, but Power FC can flash the engine check light, at pre set det levels.
No idea if motec is set this way though.

 

if Bob Rwale mapped it then why not PM him...............hes often on this site and will clear any issues up straight away..............

Possibly like the GEMS unit as above. Acts as a shift light? Doesn't do that with my M48R Pro but that is 'old technology now

Jon.

 

Having a Motec M800 myself, the check engine light defaults to be used as a shift light.

 

Spoke to RCM it is a shift light which is set to 6,500rpm and rev limiter 7,200rpm

Marty it is set up as a shift light, your limiter is not at 7200 though, its 7750.

alyn, is 6500 not "appropriate" ? ... allowing for reaction time and time to change that is a real world 6800/7000 change point given the rate the car rev's, certainly in the lower gears where it matters

cheers

bob

 

Jon you should be able to set your shift light up as the M48Pro has the same capability in this respect, unless you used all the outputs up.

bob

 

Thanks Bob for the info ,if the rev limit it 7,750rpm what revs is the maximum power?Is it best to change at 6,500-7,000rpm
marty

 

I set the shift light to the "appropriate" position given the engine, by the time you shift you will be past max power and back into the meat again. Experiment a bit, I never ever "see" the shift light as I keep my eyes on the road, after a while you pick the change point up instinctively.
