break up issues
I recently tried to make the e85 swap along with running 4 1600cc injectors. immediately ran into issues with ignition break up.
little back ground info here. using lt10s with the x4 box and bosch coils. on a s5 sp engine with 6765 turbo and makes 500hp at 20lbs of boost on regular 93. the fuel maps were tuned in and the break up wouldnt go away. i also tried changing timing maps and nothing worked. so i've come to the conclusion that the igniton is not strong enough to burn all that fuel. has anyone else using this standard setup ran into this issue? |
What afrs are you running?

was trying to tune for 11.5 tried taking it up to 12 and it was making pulls but they still werent clean

Lift up the Dwell to 4.5 ms.
And bring afrs up to 12.4 If it dosnt clear up. Get stronger ignition. |
you can really take the afrs up that high and not detonate on the e85???
|
of course especially on only 20psi.
You dont really run much richer then that even on 30psi. |
