My boost target on log is 28psi. My absolute is 31psi. That log I'm hitting 17psi on the car gauge. My previous log was 21psi target and 39 absolute and I was hitting 22psi in the car gauge. I can post a picture if you like. I'm just trying to see if I have an issue or am I making the same amount of power with less boost and the only reason I ask that cause on the first log my timing was -5degress retarted with 22psi my 2nd log is 5degrees advanced at 17psi.What’s target on the logs?
if target is not 22, it’s likely not going to hit 22 unless it was overboosting. Start with a boost leak test
Quick Share this one is the 18 psiPost the log.
Overboost with no wastegate duty cycle.Quick Share this one is the 18 psi
This one is the 22 psi
Yea wrong one oops
Simply out. Wastegate duty cycle is a % of how much the wastegate is opening to hit target boost.Yea wrong one oops
What exactly is wastegate duty. Isn't that the wastegate? Like internal and external wastegate or totally diffrent?
so how would I know if it's working or not? By my logs I'm assuming they aren't working. But I can hear the waste gate when I get into boostSimply out. Wastegate duty cycle is a % of how much the wastegate is opening to hit target boost.
The wastegate duty cycle (wgdc) is a tune thing. Not a hardware thing. The wgdc can be totally off causing over or under boost and the wastegate can be working just fine.so how would I know if it's working or not? By my logs I'm assuming they aren't working.

So running no wastegate duty cycle a bad thing? I've noticed that everytime I logged the car that I don't have any wgdc.The wastegate duty cycle (wgdc) is a tune thing. Not a hardware thing. The wgdc can be totally off causing over or under boost and the wastegate can be working just fine.
I don’t think I’m explaining myself properly. 0% wgdc means your wastegate will open at the spring rate. It is in the tune. If you’re unsure. Yamaha above is a tuner.So running no wastegate duty cycle a bad thing? I've noticed that everytime I logged the car that I don't have any wgdc.
I got my car protuned on ecutek. From what I can tell from my logs I never had wgdc. And or somthing happend between I got my car back from my tuner 5 months ago from my first log when I got the dongle which was 3 months ago. Grimspeed ecbs 3 port and dual tiel external wastegatesIm no expert here but at 0% WGDC, you're basically running on spring pressure. There should still be some kind of % indicating operation.
So was there an issue previously or was happening right after getting your car back from the shop? Also, how is your boost control set up? Internal or external wastegate? Any kind of boost controller?

You have it. Either it’s not logging wgdc or ecutek calls it something else. Likely you’re not logging it.
