Strange. My logs don’t look like that. What’s your FOL set to?

Just FYI and for anyone else that's interested, you can download the log from datazap and open it in Excel for example and you will see the full data in the log, including things like FOL, firmware, autoshift redux, boost safety etc.

Can you guys take a look at this map 6 log and help me understand what's going on? I did an additive map trying to mirror map 2, just a bit softer down low. The actual boost was way higher than what was being requested. For instance at 4k rpm the ecu psi was 13.8, target was 3.7, and actual boost was 23.4. It was definitely fast, but not what I was looking for with this map. Thanks.

I'm sure someone else knows better than me but Im pretty sure DME_BT is the actual requested boost vs ECU PSI (It may be the other way around as to which is requested). That being said I just checked one of my logs and the two values are much closer so I'm not sure why yours are so far apart? Maybe boost leak? My stock boost targets are also closer to your DME_BT values.

FWIW the rest of it actually looks ok. No corrections and AFR seems good and IGN1 advances nicely apart from the one time it drops around 6K but I would want to figure out why ECU PSI is reading so low

Lets see if someone else can chime in

That would make sense, the DME_BT values look a lot more like what I thought the ECU would be requesting. I looked back at my previous logs and the ECU PSI and DME BT are a lot closer together, I'm hoping someone has some ideas on why they are so far apart, and if it's a problem.

EDIT: I found a post from last month where someone had ECU PSI and DME BT values that were quite a bit different, and he said George told him there is a bug in the firmware which was fixed in the alpha release. Not sure if that's what's going on here.

Looks good, pumpgas is holding back timing advance a bit but there is no corrections.

I would leave it where it is unless you plan on blending in a couple gallons E85.

Just switched to Map 6.

I want to see how much E I can put in. What values should I be looking at? Trims? Otherwise do these logs look ok?

I do have a CEL too since the downpipe install, 3A44. Anyone know what that could be? If not I'll just have to pop over to Autozone and have them scan it but I'm hoping its just the rear o2. Any advice is greatly appreciated!

Pull from 3-5.
