[Link G3 with external map sensor, how?]

Yes with G4 firmware you can.

The other option is to upgrade the internal sensor to a 7bar one.

 

had a breif look online but cant seem to find anywhere uk based that has internal 7bar sensors, just the external ones.

 

i already have an external 4bar sensor so how much is the g4 firmware upgrade, i will be capable of doing this myself as per the pdf instructions and previous electronic/programming experiance

[g3 wont allow me to exceed 5200 rpm]

problem soved!

 

changed to falling edge and upped the signal filtration and bingo no i now have my usual rev range back

 

thanks for your help

On G3 firmware this is not an option on the LEM you have to use the internal sensor.

 

 

would it be possible if i updated to g4 firmware? currently have a 2.5bar sensor internal  but i need at least a 3 bar map as ive built my engine to run up to 2bar boost.

Check the polarity of the crank sensor. and also the arming voltages.

Sounds like you have some trigger issues at that RPM.

 

many thanks for the reply,

 

i'm running a hall sensor on falling edge. ill try rising edge and see if that make a difference and go from there

[g3 wont allow me to exceed 5200 rpm]

ive tripple checked all the limiter setting and even turned them all off.

 

but no matter what i cant rev over around 5200rpm part throttle/full throttle make no diffrence either.

 

its  a mx5 / miata 1.8 with 36-1 trigger wheel running toyota cops.

 

car drives great and everything seems to work except this problem

[Link G3 with external map sensor, how?]

is this possible with a lem g3? i cannot see a way to turn the internal one off and select an external one
