This is the second time I’ve gotten this log where it seems like it’s missing information. Any ideas?

Looks normal.
You won't have any timing values shown when you aren't giving it any gas.

So I have a couple of different questions if you don’t mind. I just ordered the BMS intercooler upgrade (not the race) as I don’t think I’ll be upgrading the turbos as I’d rather start looking at coil overs for next season. Anyways is that going to be big enough if I start tracking the car next summer? I am going to get the BMS WMI kit as well so is it safe to track the car with that installed? Thanks!

You should be good. You will just log to be sure, but meth will help a ton.

Log during heat wave -
06-25-2021, 05:40 PM
Wanted to post a log before I install my FMIC which was supposed to show up today but not until Monday now! Anyways it’s super hot here right now so I gave it a rip and noticed my timing was way worse. Just filled up with E30 so I know it’s not that but noticed my iat was super high, would that be the cause? Thanks

Here’s my first log with the BMS 5” stepped intercooler.

IATs are way up there in the heat wave log. Definitely affecting your timing.
The post intercooler log is better. Not perfect but better. Still hotter than you want.
Timing is better but still an little jittery. Are you using the same e85 pump? Have you tested the ethanol content? The jitters look more octane related than IAT related in the post intercooler log.

Yea I think I was running a mix that was made with e60. I did the calculations using an e60 and not e85 so I assumed it would be the same. Did a log today with e85 mixed to make an e30 and our temps are a lot lower it seemed pretty good. Would you say my IC is big enough for the situation? I’ll probably see much better temps when I add meth but for now how is it?

The intercooler is definitely helping.
A 10ish degree rise in iat over a single gear pull is ok for this size intercooler. The issue is that your outside temp is already so hot. So even if the temp rise isn't extreme, you are still hitting the ceiling pretty quick.
I would say that this size intercooler is not up to the task for your location/climate and the boost you are shooting for. Anything beyond a single gear pull and you will be overloading its cooling capacity. You generally want to keep iats below 120 degrees.
I think getting that meth kit in will solve a number of your current bottlenecks. Fuel, octane, cooling.
Remind me again. You have upgraded d pipe?

So went to check something unrelated today and noticed that I had two engine codes
121001
123701
I unplugged the jb4 to check something on XHP and used the read dme codes on MHD to make sure it was connected and saw these codes. I have the boost control cable connected too if that might make a difference. Also did a log to see as I don’t have any engine lights. Thanks
