Are there plans for Cobb to release E85 over the counter maps?

I'm stock except for Cobb 43k on car now- did a few runs today 2nd and third pulls - no room for fourth. I'm not sure what to look for, I saw boost values in the 16s on several logs, on the WOT logs (attached) there are values in the 17s and spikes unto 21 ! - is this ok?
logs look good considering your IAT is very high. the 21 psi is a boost spike during shift, nothing to worry about , is the sustained boost that counts.

What's average normal IAT values? Would changing oil/plugs/carbon cleaning help?
BTW - this is stage 1 aggressive on shell 93.
Does timing look ok?

There's isn't really a "normal" IAT value. IAT is Intake Air Temperature and it is determined by ambient temps, humidity, vehicle speed, engine load/power output etc..

There's not much that can be done to reduce IATs, an upgraded FMIC and Methanol is about it. Plugs, filters, oil etc aren't going to have any direct effect.

There's only one tming correction on the 1-2-3 gear pull so that's good. The timing itself is LOW, but that's almost certainly due to the HOT charge air temps.

Ok guyz a little issue just popped up. Log of stg 1 agressive are still looking
Fine but from time to time, in any speed above 3rd gear (3rd, 4th, 5th or 6th even) when going part throttle or flooring it from cruising the engine is bogging down and feel like its shaking. Look like misfires to me but no check engine and cant reproduce at will (as normally when trying to reproduce after it happens it goes fine). Could it be heavy boost oscillations causing something like this ? Once again no limp mode, no check engine or stored code and no half engine light. It's starting to get me worried. Also as I cant reproduce at will cant really log whats happening.

Edit : forgot to add it seems to happen at 2500-3000 rpm most time it happens (3 time since flashing to agressive)

It sounds like it could be boost oscillations. My oscillations are sort of random as well and i can't really predict when they're going to happen to get a good log of them.

i would think 6 would be good. IIRC the stock DVs work off of a 6psi pressure differential.

ok, cause i think the hks valve is leaking, car wont boost over 4-5 lbs. im wondering if maybe the BOV i have is setup for stock boost, and running the cobb stage 2 is causing it to leak.

getting a loud police siren type noise from the intake side, sounds like a supercharger.

I just noticed that v402 is available in beta. on the COBB web site.

Stage 1+ and Stage 2+ only.

Bear with me here as this is my first time logging. Other than the basics, I don't know what in the hell I'm doing. I had be running the V402 alpha maps for a few days and loaded the V402 beta maps today. I am running Stage 2+ Aggressive, stock throttle.

I did a couple of WOT 3rd gear runs for the DME to adapt before logging. Keep in mind that it is hot and humid as hell here in Florida right now. I did a couple of 2nd & 3rd gear runs and a couple of WOT 3rd gear runs. I felt a hiccup during one of the 3rd gear runs. Could be a misfire as I have gotten a few misfire codes on cylinder 4 recently.

Let me know what you guys think of the new maps in my logs:

BlueBimmer,

Why does that suck? Are you experiencing boost oscillations on a non-Stage+ map?

Thanks,

Not that I know of - just eager to get the waaaayyy smoother map that's being experienced by others.

Get yourself some DP's, an intercooler, and intake and you can experience it.

If you don't have boost oscillations, then you wouldn't be able to tell the difference between 4.01 and 4.02....

Exactly the smoother is because boost oscillations are gone...

Thanks! I went to the dealership and got a coil today after the runs. I'm having PRS make me an E85 map on Saturday and will post updated E85 logs and dyno's from map 0, Stage 2+ V402 OTS map and the E85 map for comparison.

I will be sure to check in on Sunday.
