More boost but timing still needs some work.

I might add 1 gallon of E85 this weekend to see if logs improve but overall power is crazy and my butt dyno is very happy!

So I was a bit bored and didn't want to wait for another map revision so I added 2 gallons of E85 and topped off with 93 octane.

Its amazing how much my timing was cleaned up and felt so much more power mid to high rpms. Also, IAT were consistently low, although it was a cool night here in Florida.

Mind you I've requested solely a pump 93 octane custom tune but DAMN its amazing what a couple of gallons of E85 will do! Now I'm considering just tuning for a higher E-mix!!!!!

Think you found your sweet spot on your octane! GREAT looking log

Yeah I was surprised and have been very hesitant to use E85 but now I'm a believer lol!!

In reference to my 93 octane revisions I was advised by PUREBOOST to check my spark plug gaps and that they should be set to .018 instead of the .022 that I currently have them set to.

My question to that is if I'm running an E-mix, should I still regap to .018?

Iíve been running e30 Map gapped @ .22 since 2015 with zero issues. Iíll be re-tuning for e50 by April, if I need to gap down to .18 or maybe split the difference at .20 Iíll do it then. Just need to watch timing/misfires and adjust accordingly

This is what i suggested about a week ago . Yeah the octane from just a few gallons of E85 can make a huge difference, and you can reap the benefits even on a non-E tune. The advantage of going to a custom E tune would be to throw some more timing in. With your XDI you might be able to get some more gains from that without running out of fuel.

Absolutely glad you suggested adding some E85 and will ask for a revision running this E-mix. I'm curious just how high of a mix I can go while still making power. Of course a full E85 tune would leave any guess work for E-mix ratios but dont want to have to upgrade my LPFP. I'm guessing E40-E50 might be the max for the XDI-35 and stock LPFP.

I looked at two of your recent set of logs after adding the E85 and your STFT are still quite negative (pulling fuel). Maybe the tune is intentionally a bit rich in its current state, but even with the adding ethanol, the DME is still pulling fuel. So, you may not even necessarily need a revision based on adding the ethanol. Maybe just sent those 3 logs back and ask if everything looks good? If you ask for a revision running the 2 gallons of E85, he might add more timing, then you will be back to being at the limit of the octane of the fuel.

What i have found running MHD 2+ with CA 91 octane (no added ethanol) is that power can be inconsistent due to timing being pulled in some situations but not others. I have some 4th gear logs with perfect timing (zero corrections), but others with up to -6 on one or more cylinders. That results in a very noticeable difference in power. I guess what i am saying is you dont necessarily want to be tuned to the limit of your octane.

Not quite sure what the LPFP limit is, but some say its not needed unless you are running port injection. With the XDI 35 being +35% increase in capacity and E85 (assuming its actually 85% ethanol) being about 30% lower energy density than pump gas, you would basically be cancelling out the benefit in terms of pushing beyond the limits of the stock HP capability of the stock HPFP with full E85. With a PS2 and custom tune, you probably wouldnt want that as you would be leaving power on the table compared to a mix.

The mixing can be a little annoying if you drive the car long distances frequently, especially if access to E85 is limited. In my 3000gt, which is no longer my daily, i just add equal amounts of pump 91 and E85 at every fillup. Of course this means i never go to a completely full tank - usually just 5 gallons of each so i know i am keeping 50/50 ratio. Adding _X_ gallons of each is usually easier than trying to guess how much total fuel you need to reach a full tank and allows you to keep the ratio consistent. For a F30 this would probably mean going down to maybe 1/8 tank and then adding 6 gallons of each at the next fillup.

Finally, not sure where you are located, put check out the pearson fuels app for E85 station locations. They claim to be 83.3% E85 consistently.

I've sent logs with the 2 gallons of E85 to my tuner and waiting for a map revision. I'm sure he will add some timing but I'll report my experience with new logs.

Always appreciate your in depth advice and process thinking. I'll be regapping my plugs to see if that helps clear up my timing as well.

From what I've read and researched about the stock LPFP, it's only necessary when using port injection. Also, I figured running full E85 might not render much gain compared to e40-e50, so if i go further down the rabbit hole of higher emix, then e50 might be my max!

Looked at a couple of them and it looks like you have some timing corrections now. Maybe he added some more timing since you added ethanol? Would need to do a side by side comparison of actual timing on each cylinder compared to old logs to find out. STFT are still negative so you can probably just put some more ethanol in with this revision.

Yeah it looks like a bit more timing was added when I compared it to my previous logs. But I'm also going to regap my plugs to .018 and see if that first will help with the timing corrections before adding more E85.

So I was looking at my OTS logs for PS2 and my STFT have always gone negative and that was with no timing corrections
