Why go full E85 with the IS38 at all? E30 will get you 95% of the way there, and you're already installing an ethanol gauge. Less chance you run out of LPFP duty.That brings us current. Only thing left to add is pictures and memories. And I have my share!
Next challenge is 6/7, Track Night @ HHR, where Miguel breaks his own damned rules and goes racing in the summertime.
Good thing I run a small shop and have special pricing on fluids, filters, and assistance.
@MonkeyMD will keep me safe.
Long as the intercooler install 5/27 goes to plan, I should be in good shape.
OH! I almost forgot. I checked my tires last week after the TNIA event and found them all at 4/32", right rear (newest) @ 5/32".
These poor meats have been abused like a corporate shill. So new Michelins are in store by end of month.
I have a huge credit for the old ones, and a $110 rebate from Michelin, and 5% off for using my DT card.
Gotta be frugal when you're a man with kids in America...

For the 6/7 event, I need to:
-Install my TyMate TPMS sensors that monitor psi and temp
-Download and practice on Harry's Lap Timer
-Install said intercooler
-Debate if I wanna go full-retard and just purchase the AutoTech HPFP and E85 tune.
It's a stretch. Will prolly wait.
This chit is addictive and expensive. A coke habit would be more budget-friendly. Just being real.
Simplicity and never having to mix, nor pay 93-octane prices. It's a convenience factor. E85 I can go straight to the pump and get E70-E80 (whatever the concentration is).Why go full E85 with the IS38 at all?

Completely understand that, but you're already paying 93 prices with your current tune, right? If it's a shared E85/93 pump or one you use often, you can usually guesstimate a perfect ratio every time. For me it was 4/9.1-2 on an empty tank. Adjust the ratio as needed if I wasn't completely empty. Definitely won't give you the cooling benefits, but could prevent a LPFP being needed.Simplicity and never having to mix, nor pay 93-octane prices. It's a convenience factor.

It's a nice time saver, TBH. And the added cooling benefits are outstanding. E30-ish gives you more knock protection than straight 93, but nowhere near the latent heat of vaporization that E85 offers.
You just hit on the other reason: I don't want to have to guesstimate concentrations. I know my car takes 10.5-10.9x gallons of fuel at fill-ups, but the E85 concentration varies at different stations throughout the year.Completely understand that, but you're already paying 93 prices with your current tune, right?

They claim 3% either way is ok. So E27-E33 should be fine.You just hit on the other reason: I don't want to have to guesstimate concentrations. I know my car takes 10.5-10.9x gallons of fuel at fill-ups, but the E85 concentration varies at different stations throughout the year.
I worry I would be mixing for E20-25 some weeks and E40+ others, the goal being E30 every time.
The variance would either due to my own error (I'm human and blonde)... or the unavoidable errors of pump concentrations skewing the outcome.
I will have a convo with EQT since their tuning tables and adjustments for ethanol variance is the single biggest determining factor for me, along with the LPFP's behavior.
This. My legit fear. I lose my chit when the automated machine tells me to "get bent" when I'm trying to give it money for petrol...Oh one last thing, some stations don't like you using the same credit card twice. 2nd transaction will be canceled. Looking at you Circle K on 130 & 969
Oops - what's OS?Subscribed
You know on OS you can run flex fuel or map switching etc (could make pump, E85, and 3 maps in between for varying fuel mixtures)...
Open source. If I wasn’t already tied to Cobb that’s where I’d beOops - what's OS?
I’m sure Cobb’s flex fuel will finally be released in like 2Subscribed
