On stock fuel pumps? I've not really looked into ethanol yet as I'm still learning the ins and outs of having a turbo vehicle and modding. Any precautions or prerequisites that I should look into prior to running an E-mix? All mods that I have added, i have been trying to precede with some sort of engine protection measure (though, I still need an OCC setup). Plugs, pumps, injectors, etc?

Terry @ BMS · 08-05-2019, 04:06 PM

For the higher maps on E85 it can be a little hit and miss and require experimentation. But generally 30% E85 and say map5 for the SS and map2 for the RS are safe bets.

jrobohm · 08-05-2019, 04:09 PM

Up to E15 is the new norm for car manufactures. Beyond that you will definitely see higher trim numbers and lower gas mileage. If you have an E85 supply - you can try a fuel calculator like the one below to play with fuel blends. Be sure to take it slow on the added E content and be sure to log!

I have been running up to an E30 blend for over a year. With the addition of Fuel Wires I saw an improvement in my AFR #’s.

YoshiQ88 · 08-05-2019, 06:53 PM

Did you happen to take a peek at the logs I posted, Terry? Curious as to how I'm looking as it stands

Fourg63 · 08-05-2019, 10:31 PM

Looks pretty good. I wouldn't worry too much about that timing dip at 5600rpm in the second log. I've tried to get rid of it but I think it's just the nature of the beast when in higher gear regardless of fuel or boost map. Now, let's talk about the non-functioning charge air temp sensor.

Serstylz2 · 08-06-2019, 04:02 AM

I'm still unsure of the long term effect the additional ethanol will have on rubber components on stock fuel pumps. I would hate to being it in for warranty work or a CEL and they realize my pumps are toast due to added E

YoshiQ88 · 08-06-2019, 05:57 AM

Let's, thoughts? Has been that way since before I added any mods. Leads me to believe that it is an issue with the JB4, I double checked all harnesses related to the JB4 install.

Also check out the WMI AFTER the throttle is no longer 100%. Even after the pull it was hanging at ~82 on the gauge. I had to go WOT again and then let out to get it to go back to 0.

bump...Terry please take a look.

Here is the first log after the trans temp issue started. All logs prior were "0" trans temp and all logs since have had a value of 32. Looks like it started with the fw7hex update, I've attached the log and a screenshot of my update schedule.

Not to me selfish, but I look at a ton of logs for folks....I want Terry to look at MY log

Terry @ BMS

I wanted to ask if our cars will ever get launch control???

Have you played with the boost by gear?

YoshiQ88 · 08-06-2019, 09:19 AM

Lmao, whoops. I have seen you contributing a good amount to the thread, honestly, I thought you were with Burger. In hast I totally overlooked exactly what youd quoted, MY BAD lol.

No worries, just breaking your chops.

See Terry, give your boy some support over here!

BMS - Where are we on having an OCC from you all? The Mishimoto OCC seems to be the only real player for the VR30 and I know BMS must have something in the works?!?

Tuning side looks fine to me. You're under boosting in 3rd initially which is why AFR is mapped leaner there. On the WMI reading on the app probably just the app missed the last update to signal 0.

Yes we have a BMS kit on our car, will be releasing soon.

YoshiQ88 · 08-07-2019, 10:12 AM

Mind taking a look at the two logs I posted after adding fuel wires (page180). Also have an issue after installing hex7 where trans temp is stuck at 32. Posted a screenshot/log of that as well.

I'm not sure I follow how under boosting would cause the air fuel to go lean and not rich. but put that aside for a second look at the log of the wmi it still shows 100 after throttle is already cut. Can you explain that?

AFR (and everything else) is mapped on boost. With boost so far below target you're running in a leaner part of the mapping.

The WMI signal is filtered and not based on the solenoid so it's not going to exactly match up with actual flow around the edges. Meth solenoid is closed under many situations and throttle or pedal less than 70% among them. If meth was flowing when the throttle was closed you'd get tons of misfire codes and the engine would stall out. It's not.

Interesting, I'll have to do some back to back testing with the boost by gear on vs. off and see how it changes. Thanks for the explanation.

sky777 · 08-14-2019, 02:23 PM

Hi Terry, could you take a look at this log to see if it's running good? 3rd gear pull on pretty level road. Any concerns with Ign1 dropping zero? Thanks

slimjim2525 · 08-14-2019, 08:24 PM

Terry, can you look at my log. This is on JB4, map 6, +4 at 3k-5500 rpm. Also can you explain a little about the fuel wires. Your description on your site says it leans things out at higher rpm's. Do you really wanna run lean at higher rpm's? In racing we say lean is mean, until it blows.

What fuel? Ign has to go fairly low due to the 20psi hit here so that isn't necessarily surprising. But if this is just pump gas I think I'd evaluate lower boost levels.

Really old firmware, I'd update that.

As described the fuel wires let the JB4 run a leaner AFR more similar to the high 11s the flash maps target.
