EQT E-Tuning Q&A

[ChrisMk77]

Thanks.

EQT says to run their E30 map with 30+/-3% ethanol content. I was at about 29.5% when logging.

What's DA?

Density altitude and with your temps and atmospheric pressure it is fairly high, in combination with a boost referencing tune it leaves you with more fueling headroom.

Also if you are using a continental flex sensor I have seen several people claim that they read a little high.

Does any one of you guys have a rear diffuser? I'm well aware that it is just for looks

Aerofabb

Yeah, I heard Aerofabb makes quality parts with the best fitment. So I'm curious, how much weight does it add? I'm looking at the CJM fin style diffusers but I would like to gather all info to not have buyer's remorse

That part probably weighs less than 3 pounds.

I like that tucked fin style, good price too

ECS CF Diffuser

Many say it's a waste of money but honestly, I think it makes our cars look so much better than OEM

I had the ECS Gloss Black one on my GTI. No issues with it. They don't make any I like for the R, so no difuser now unfortunately.

Also, why is this discussion in the EQT Tuning Q&A?

I do indeed the continental sensor. I'll look into it, thanks.

Edit
Quick search says Continental has about 10% error. Does that mean my E contemt is in the 20-40% if sensor says 30, or is it 27-33%? I'm confused about what number those 10% are taken from.

Edit2
My continental consistently reads 10% when I'm running pure 91 gas (10% ethanol).

Looking at the continental doc, it's +/- 5% ethanol error. So if it says 30, it could be 25-35. Sounds like yours is calibrated fine to me tho. Personally hate the e30 mix crap, too many assumptions about content in the pump vs. the lines vs. the tank.

Very useful fact sheet. Thanks.

 

[Ed @ EQT]

Can you guys take a look at my log from today?
'17 GTI, EQT E30.

Thanks.

I'm particularly curious about AFR (actual vs. target), rail pressure, STFT, LTFT. I see my AFR is 12.35 for about three seconds after I shifted to 5th.

Looks great. You could try mixing a slightly higher ethanol content.

Thanks for looking.
But no more than 33% ethanol?
