Default Port injection questions and which BEF? - 01-20-2022, 07:02 AM

There isn't an E85 or PUMP BEF's for port injection and stock turbos, so which one should I use?
2009 335xi /w stock turbo's/port injection/stage 2 bucketless/JB4 PI controller (NO FLEX FUEL kit)

I Would like to run 50/50 e85 and 91 octane

What should I monitor after a new port injection install? AFR, pumps, trims, fuel enrichment (is that the PI flow?)
Thanks!

If you plan on using port injection, use the "PI" BEF.
If you plan on using pump, use the "pump" BEF
All port injection setup and settings can be found on the link below.

If/when only running pump gas on stock turbos...no need to run PI and I'd run the pump flash.

When you run E85 or significant mixes of ethanol, then I'd run PI and the E85 BEF.

GC2 is Game Changer turbo upgrade. T7 is the version.

In my case should I try JB4_IJE0S_E85.bin for port injection? There is no JB4_IJE0S_E85_PI.bin?
Is that an issue? If so I'll disable the port injection in the meantime and go with the pump flash.

Thanks again

Not a necessity. You can still use the PI BEF

No.

Start with: JB4_IJE0S_PUMP_USA.bin
which you can use as a daily BEF on pump fuel and log.

When you have access to e85 you could switch over to the JB4_IJE0S_E85_bin
But you can run up to 40% ethanol on the pump BEF or even the Race BEF and log and then make tuning changes based on those initial logs.

Are you using the JB4 PI controller? When looking at logs "Meth" is your PI flow.

Either PUMP or E85. With E50 shouldn't need much PI action but we'll see how the logs look.

Thanks guys, here's a log on map 1 with out any backend flash and should be about 80% gasoline. If anyone could take a look before I switch to try full e85/flash and make sure the port injection is flowing. Yes I have the JB4 PI controller but I thought PI flow was logged under Fuel_En not Meth.

'Set "meth scaling" to 99. When port injection is flowing you should see a meth flow trace appear in JB4 logs that mirrors "fuel enrichment" (port injection dutycycle request). If the trace is stuck at 0 there is likely a wiring or setup issue.' - Taken from the PI Setup thread. If you remember when you wired the PI controller, you wire into the "meth" wires on jb4 which is why meth is PI flow.

On that note looks like PI is flowing. Looks like you could use a little more fuel bias to lower AFR's a tad but I'm no doctor.
