What’s needed to run Pure600 on a 535i? (or any non 335)

Pure 600s fit the bill with what I’m looking for in upgraded turbos. Given pure only makes them for the 335, I know the rear turbo is different.

My research confirms that I’ll need the rear...

Thanks Cannon, that makes sense. So the spike in boost is the leftover pressure being read by the TMAP in the CP before it gets recirc'd through my DVs?

I have a few more questions:
1) Does that...

what should over/under target be in ideal conditions?

newbie here — what is considered normal for boost above or below target? For example, is anything above or below 2psi out of range and therefore has some tuning issues?

I’m trying to set up menu...

I’ve researched this a lot and most people who have experienced both say that MHD OTS is smoother, but MHD BEF with JB4 is much better than JB4 alone.

How are BEF maps for JB4 different than OTS flash only tunes?

As title states, I’m curious. Do BEF maps set boost targets to 0 and allow the JB4 to manage boost control? I understand both OTS maps and BEF maps will have values for fuel, ignition timing, etc —...

Installed DCI first timer, rear cone doesn’t look like install pics

I went and installed the rear first instead of the front — it’s angled a bit down. Tube only fit in about 1/2inch into rear inlet but I think clamp is tight and sealing well. Front seems/looks fine....

Thanks Terry. Do you know to what level of accuracy the virtual sensor operates at? Map5 ok to auto tune if I chucked in a few gallons of e85?

Also, would pump BEF be the best flash here?

Does JB4 read ethanol content without a sensor (map5)?

Curious to know if a flex fuel sensor is needed or if Map 5 can work standalone. Also, does the E content PID work without a sensor?

Thanks. Is this achievable on stock 1.75 inlets? Can BMS 2" inlets fit on stock turbos?
