Fuel IT Flex Fuel Sensor, Port Injection, Bigger Turbo?

[razorlab]

Thank you sir you’re a gentleman and a scholar

Just checked one I download awhile ago. JB4-E85-PS2 and it has the fuel scalar at 1.30 instead of the normal pump gas 1.00

Want to send me the ROM you are using and I can check it?

Sure I can email it over seems you can’t attach it here. If you wanna shoot me your email, I can send it to you?

Looks like they are also increasing LPFP PWM to 100 (max) and the fueling correction factor in the higher RPM from 0.98 to 1.4

I’m using the race bef fyi but Terry had to tweak it because throttle settings got reversed not sure if he changed anything else in mine

Was going through the next round of items to order, plugs, cabin filter, catch can and I was considering the Fuel IT Flex fuel kit. However am I paying $500 to just see the E-content? I have the JB4 with Terry’s backend flash, i know I can connect the sensor to the JB4 and see the readout as one of the guages but does it really take advantage of knowing the content and if so is there any real difference? I also understand they don’t actually measure e-content just the absence of gasoline so other factors can throw them off.

Just seems like it would be better to put that toward either port injection and run full e85 and go Pure 850. SInce we are on that topic…

Would you go port injection first or upgraded turbo then port injection, Would love to know your reasoning either way?

I’m already running e40 blend, FBO, car made good power/tq

You are going to want the motivmotorsports reflex kit. 100%

It will allow you to have true flex fuel even with port injection. Meaning you can go to the pump and fuel up and your car will essentially auto adjust.

Looked at the ROM you sent me.

Fuel scaler is 1.15, normally 1.00 for pump gas
LPFP PWM is set to 100 from 90

So that seems about right. Thank you! Any suggestions?

What Ethanol mix are you using? Keep an eye on your fuel trims.

E40. Trims are staying 40 and below at 22/23psi

I can scale it higher than .15 if you want, would bring your trims even more in check.

If Razor is willing to make the rom changes Id do it. You want to be much closer to 0 (JB4 25 = 0) since you are on a BEF and have the capabilities to control fueling.

If it’ll help then for sure. Is it just that 1 setting or should that be in conjunction with other settings that work with it?

here you go. 1.30 scalar instead of 1.15. Should help with your trims.

Thank you sir! Will update at my earliest and run it to see how it she does.

@razorlab here is a few runs after updating with the new fuel settings. I also just installed new plugs tonight as well since the manual says after 48 months and based on what i was reading they should be gapped at .22 so I got some of those nice iridium ones from burger and put those in. Idles nice and smooth….

Overall boost is up 22/23 and staying up there. Not a lot of throttle closures except on the shifts (well that first run was spinning so I expected that one). Timing seems a bit more and trims are in check and the car is pulling really hard.

3rd gear run first run trims kinda spiked up but the later runs it didn’t do that however it was spinning pretty hard on this pass so that could be it.

This is a 4th gear run less spinning seems more normal
https://datazap.me/u/phantomx2k/fuelscaler-4thgear?log=0&data=1-4

This was the final one 3rd/4th/5th gear run

When you got a min take a peek please and thank you!

for comparison here is the other day before the scaling change I may be mistaken but seems like all of tonights runs seemed to run a bit more timing potentially a bit more power?

sorry for the log dump but appreciate the feedback and the help! You guys are awesome and really appreciate the help.
