ECMlink Problem Timing Retard...

[Luciano Bernardo]

Hi, Dear Friends

I'm 3 years old with this problem and nobody can find out the cause, I'm new here and if anyone can give an opinion, I appreciate it. In annex the LOG, it delays the point dratically when it should advance and then comes back ahead, generating leaps between 4 and 5K. I already changed 2 MDP sensor AEM 5 Bar because they told me it could be him.

I have Pistons Wiseco Forged, GSC Cams 268x268, ECMLink V3, Speed Density, AEM 5 Bar, Walbro 450 Rewired, GT3077R Kynugawa, Exhaust 3´, Engine head 1G, Valves + 1,00mm.
