thanks guys. from my searching on this forum i did come across dashpot. i dont seem to have auF1704 though. i will try change the decel load and see what that does. although i would like to understand why its doing it in the first place and not with the speed signal disabled.

have attached 2 screenshots. basically any time i get off the throttle completely. tp raw without speed signal is about 155-165. with the speed signal its 180+. can feel a noticable loss of compression braking. it basically coasts.

Pcmtec new starter here. playing around with my barra converted f100. have fg turbo ecu. recently changed speed signal source to my canbarra. now on decel ive lost a bit of vacuum. the throttle is hanging open slightly on decel. when it gets to a few km per hour it goes back to normal. any idea where i should be looking to sort this out? have attached a couple of logs to compare.
