I suggest you add a gallon of 93 and see... I ended up adding 2 gallons to get acceptable pressure when I was that low... but start with a gallon... 1st/2nd gear pull is where I saw the biggest drop...

Ok cool. I'll add a G of 93 and log again.

I gotta get an analyzer... I won't know E content in my tank after adding a gallon of 93. It's a guessing game after that.

amazon has the tester and the hose... lol... it's the only way to really know what your car will run on.. then you can always mix for that... E20 is pretty simple for me... 2 gallons per tank... E30 is 4 gallons per tank... I think if you went that formula it will work cause you added 4.21 the first time right? it would be a 1/2 gallon of E per 1/8 of tank to fill then.. pretty easy... so 3/8 of a tank would be 2.5 gallons... 1/4 tank would be 3 gallons... then your fuel pressure should be okay... maybe.... might have to lighten it up a little more... logs will tell... but for the most part should work..

LoL true... I have the tester and I also have a small handheld pump that I can use to syphon some out and test. I think I'll do that, add a gallon of fuel and test... I'll let the tank run down to E and fill up on 2G of E85 and the rest with 93.

Wait I thought you were running E30... that'd be 4 gallons per tank... also it's not really good to run down to Empty if your accelerating, fast cornering etc due to the fuel pick up... it is always recommended minimum 1/2 tank if tracking your car... so be cautious driving...

I also read somewhere 3.8 gallons was the magic number for E30 for these cars... go the 4 gallon route and log... now that I think about it... I calculated I was on the edge of E19/E20 when I added the 2 gallons since I burnt 2 gallons already when I added...

Yessir, E30 is what I'm currently running. I calculated it to 3.25 gallons of E85 with the amount of 93 in my tank. If I wanted to get a true E20 I would run the tank down to emptyish and add 2G E85 and the rest with 93 right?

If you want to run E20 ... yeah... but your tune is for E30... this was your first full tank ...no? ... or you only did a 3/4 tank or something? ... for E30 full tank would of been 4.21 by the calculator for the first ever fill up... but I think you got the picture... for now just add the gallon and log it.. 1st/2nd pull you don't really need to go over 45/50mph ... basically can do it anywhere... I think the 1/8tank =1/2 gallon E is safe if you want to be lazy for E30

So I had about 65% of 93 in the tank before I added E85. I couldn't get to a gas station so I basically subtracted 1.14 gallons of 93 from the 4.39 gallons of E85 the calculator was calling for. I added 3.25 gallons of E85 which equates to E30 in the tank, not full but correct mixture.

Ooh.. I see.. well that stinks you don't have gas on the same pump... moving forward just fill up basically a hair below 3/4 tank and the rest "E" and you should be good to go.. just drive around doing hard stops to sloosh it around..

Thanks man, you've been extra helpful and I really appreciate it.

I'm married with young kids... stuck home working and with the whole family cause of pandemic... tired of the news... no good movies to watch at this point.. this is my escape basically... lol...

Actually fill it up to 3/4 on the nose and the rest "E" and it should be just about perfect...

LoL same here man. I have two of my own but I'm an essential worker so I've been working non stop. This is also my escape from the madness.... So 3/4 93 and the rest E will get a 15.8G tank to E30 give or take...

Here's the thing. If my logs still look like this can I run a E20 mix with the E30 map or are we looking at an upgraded HPFP?

Here's a thought... If I syphoned some fuel from the tank and used my tester, would it give me a good E reading?

No.. it will pull timing/boost... you'd have to go MHD for that... if you saw my last log I was getting 15.5 timing on MHD E20 map 1st gear... JerryBMW on a full E85map is getting 19degrees timing on custom MHD map 4th gear pull.. that blew my mind.... so in other words.. you run a E30 map you gotta run E30... you can run the 93 map on E30 if need be....

As for the fuel pump.. looking at JerryBMW... he was dipping into the high 1800s with a spool 150... that's why I'd go dorch 2 or spool 180... now do I have to add a new lpfp???... don't know yet... or just go WMI... I haven't heard anyone complaining about WMI so might just go that route... or just be content with everything as it stands... yea right... lol....

I can order BoostJuice from amazon prime... lol...

Attachment 2460995


for those first time looking... the 268whp is not the cars max hp... this is a first gear pull... whp in fourth gear would be north of 400whp with perfect timing...

That power curve is terrible, why rev past 6000 at all?

I didn't know you could run the 93 map on E30... Any drawbacks to that?

It's all about keeping it in the rev range/ Hp for the next gear...

Oh that one... that's because of second gear... look at the cleaned up graph couple comments down
