Ecumaster forum

hi to all who read my thread!

hope some one can give me some info on this topic.

i run a emu on a 4EFTE toyota engine. there was a bosch coil on it which did not had a build in ignitor, but had issues with spark plug leads falling off and fed up with it.

so i put some K20A honda coils on it because they fit really well on this engine,
after that i change the settings to built in amplifier and put in dwell times i found on the motec website.

the only problem i have now is that te car sometimes doesnt start which i have think has something to do with the dwelltime being to short when the voltage drops when you crank the car over to start it.

these are the settings i have in the emu now:
voltage dwelltime m/s
8 4,8
9 3,5
10 3,0
11 2,5
12 2,1
13 1,8
14 1,7
15 1,5

what is save to try without frying my brand new coils ?

thanks for now! steven

Hi
your dwell time value is too small

I run a lot of k-series engines, on these settings and everything works fine,
these settings are calculated from K-pro ecu tables

hi mate!

thanks a thousand times for taking the time to answer my question!

i thought that my issue where dwell time related because i never had any starting issues, but i was a bit afraid to bump them up!

thanks again! ill let you guys know if this solves my issue!
