Seems like I found what was happening... but haven't solved it yet...
I tried with an other lrp flow works that I had installed on my pro10,
after installing it on the sc10 4x4 I was able to pull trigger for 2-3 times and after it started with the same brownouts as before.
This time I could see that the capacitor leg gets broken/dessoldered
I've went to the shop and bought some more capacitors 25-35-50v / 2200-3300 microf.
Installed one of them on the speedo and same as before, after 2-3 times pullling trigger, capacitor gets dessoldered.
Soldered a new one and set the throttle EPA to 60%, could pull the trigger 7-8 times and gets dessoldered.
IS LRP FLOW WORKS ENOUGH FOR DYNAMIC 10L??????
