First Log On Link

[Disturbance]

This is my first log on link and would really appreciate it if you guys could look it over and see if everything is looking good, theres a couple pulls through the gears and some normal cruising. One thing thats weird is when i get off the throttle it almost acts as the cars dies and the log stops on link, any ideas what that is? thank you for any help

Might be your ISC, but we can't tell because you're not logging it. However, that does not explain the log stopping maybe a connection issue...

ok i will add all those logs to my next one, i just had a CEL kick on last night. Is there a way to read the CEL on link?

Yes, under the DTCs tab which is accessed from ECU config.

Ok so i read over all the links you posted and made it so link is logging everything that it should. I just took it for a cruise and its still having the weird cut out issue, it only happens when im trying to just cruise and am feathering the throttle, im really lost on this. It happened in the log multiple times and im sure for people that know what theyre looking at will be able to find it . I did a 3rd gear pull towards the end of the log as well. Sorry its kinda long i just wanted to make sure i captured everything i could. Thank you for helping me out so much and taking a look.

From the looks of it, your injectors are cutting out in those problem areas. Looks like your idle switch might have a problem and is triggering coasting fuel cut prematurely. You can see the idle signal goes high even though you are still on the throttle. Try simulating the idle switch in link. From ECU config, go to the RPM/TPS tab and select "Simulate idle switch from TPS."

Also, you want your TPS volts around .63v. Right now it's sitting at .65-.67v so you should try to adjust it a little more.

That took care of it. Thank you very much, I was really hoping some sensor didn't go bad already. Yeah I must not have tightened the bolts down enough on the tps because I did have it at .63v I didn't want to strip them out. Ill get that taken care of next. I also am having bad boost creep at full throttle. I have it set to 10 lbs and when I'm making a decent pull at wot it starts to climb up almost to 20 on my gauge forcing me to get off the gas. Is this due to just not have an external waste gate?

Great! No problem man.

First and foremost, you need to verify that the wastegate is operating properly and move on from there.

With regard to boost creep, this should tell you everything you need to know:

Basically, fluid (exhaust gas) likes to take the path of least resistance. In this case, there are two paths: through the turbine housing (spinning the turbine wheel, creating boost), or through the wastegate passage (diverted away from the turbine wheel, limiting boost). When the wastegate passage is the more restrictive path, you get boost creep. The most common problem areas are the wastegate flapper hole and the o2 housing passage.
