Try turning your BC duty cycle up to about 75% and see if it starts to help also. If you notice it getting better, go up until it clears the spike.

 

Sorry for the late reply. On my way home now, when I get there I'll fire up the laptop and post a full reply

 

First problem I see - your boost controller is set to activate too low. What size spring do you have in your wastegate? If you don't know, deactivate the boost controller in Kpro and take note of your max boost on a 4th gear WOT run. With a 50trim, you should hit full boost around 5k. If its creeping, you will see your boost do just that (creep) soon after that RPM all the way to redline. Here's an example of my old setup that crept like a mofo:



Target boost was 14psi. Cause = Wastegate too small.

Back to you. Look at your logs and see if your MAP log looks similar. You need to change some of your settings to get the proper resolution in your logs to see this. More on that in a second. If your log wavers like my old one dyno chart, you've got creep. That aside, once you're 100% on your wastegate spring, set your solenoid activation 1psi lower than that number. I have a 7.5psi spring in my 44mm Tial, here are my settings (different setup & tune from the above dyno):



I'm gong to raise this to around 6.5psi next time I get a chance. Right now, I can hear the wastegate open for a split second, close, then open again a split second later. It bothers me. Play with yours to get it smooth.

KPro out the box has a bug (or feature, depending on how you look at it), where it doesn't display boost in datalogs properly. The min and max settings are all sorts of skewed, but I've found the following settings to work best.

Go to Options > Settings > Sensors and setup "MAP" to look like this:


And in Options > Settings > "Units", be sure it looks like this:


After that, your datalogs should looks more like this:


Keep us updated!

 

Thanks for the info spec! I definitely have creep. I changed my settings and played a datalog I have saved and it's creeping bad. I pretty sure I have a 7psi wg spring, but I'm waiting on a reply back from the old owner of the kit to confirm. If it is a 7psi spring and I set my solenoid activation to 6psi, what exactly will this do to alleviate my creeping issues?

 

I'll get back to you on the solenoid activation when I'm 100% sure of the ramifications, right now I'm not and I don't like to give out misinformation.

Turn off the boost controller and get a datalog of some pulls and post up.

 

I just ran the car off the wastegate spring (4th gear WOT) and my datalog is showing 6psi at 5000rpm. It got up to 6.7psi by 6500rpm. I ran out of room after that. So 6 or 6.5psi spring maybe?

 

Need a full pull to be sure

 

I set my solenoid activation to 5psi and it is doing exactly that. I still have yet to to do a full WOT pull in 4th, but I'll update as soon as I get a chance.

 

Any updates?
