Shouldn't be. I was looking over our PUMP BEF and the faults deactivated like under boost and throttle airflow variance don't related to readiness testing? 3106 is enabled as are the DTML faults.

Been reading through this thread. I already have a samsung galaxy tab, ordered the dcan cable and the otg cable, and about to buy the mhd flasher. Super pumped to try one of these BEFs along with map 5 and 40-50% e85 on top of 93 and the real cold weather. Curious to see how the BEF will work with map 5. Map 5 has been amazing so far for me [16.8-17.5psi], been nothin but smiles from my end.

I'll be sure to post logs in the tuning/help section of the forum and if need be Terry I'll shoot you an email.

Is it possible to turn the ***** code off and any others that pop up on the daily?

Yeah, you should be able to just unplug the maf with anything above FW 5.10. I ran it for a month before the BEF and noticed my mpg dropped by 2. But idle was crazy smooth.

So you guys are running MAF'less now days? My idle has been horrible lately. It will smooth out only if I reset adaptations via MHD app (doesn't seem to work doing JB4 1/7)

On the idle adaption reset, it only works with ignition on, engine off. Resets fail if engine is running.

I didnt realize the e series could not run mafless. So can I just unplug the MAF and reset adaptations?

Works on some cars, not all, for reasons yet unknown. It's an area of development.

How do you have the pipe connected to the turbo? I assume you have the pure inlet and then just a silicone coupling?

I've been running MAF'less since September last year when I swapped PI controllers (from AIC6 to BMS PI Controller). My car has been running flawlessly, no codes yet.

Should probably rephrase, it was with engine off key on. And it does seem to smooth out the idle, but only for one cold start. Doing it with MHD lasted till this morning, so about the same. Just found this out a couple hours ago.

So it does work, must be something else causing this issue.

Kind of weird because it really only started doing it when I went back to full tank of 91 octane recently. Never had this issue running mostly E85.

I was trying to make changes to the AIC6 PI map because I was running really high AFR's. I struggled so much just trying to communicate with the AIC6 so decide to swap it.

I'm really happy with the BMS PI controller. The controller is plug and play, no programming is required. Also, I noticed that I could run lower AFR's values by 10% to 15% less (depending on boost level) after the controller swap

Just not having to deal with an extra program to program and log the AIC6 is a huge plus. Not to mention the ease of use, feedback to the JB4 for extra safety, etc. Well worth the swap IMHO especially when you might be able to sell the AIC6 over to a flash only guy who hasn't discovered the JB4 & PI controller yet.

What benefits are there to running MAFless? I am just now hearing about this. I am FBO with BEF if that matters any.

Just unplugged my MAF sensor as well, idles perfect now. Runs the same as before above idle. Real test will be cold start!

Long day of exams my brain is fried...I disconnected MAP on accident, ran perfect no codes. Running MAFless runs good too. Does through a couple codes though.

I will flash back to stock and see what happens to the readiness status. On that note, can I modify the fuel scalar and AFR's on the stock map and then flash it as a custom map without any detriment? In other words, does flashing back to stock via "stock map operations" and manually flashing the stock map via "custom map" yield the same result?
