And would it be further possible to use the Req. Boost values (or wgdc) from the DME to set the boost control point?

In this way, would it be possible to run external wastegates either on a single or twin turbo N54, because the DME is getting the boost it asks for; just not in the way it thinks? And the DME could handle fueling/timing completely through the flash via Cobb/whatever. Understanding in this scenario that you'd be sacrificing any of the map-switching and auto-tuning benefits of the JB4, and you'd have to re-flash to change boost settings. Essentially, the JB4 would be doing nothing but replacing the idiotic stock boost control system on external wastegate systems.

Is this a mode that could be programmed and sold by you on the JB4? ]]> N54 DallasBoosted http://www.bimmerboost.com/showthread.php?39851-JB4-as-boost-controller-only Morning project http://www.bimmerboost.com/showthread.php?39840-Morning-project&goto=newpost Mon, 20 May 2013 18:08:57 GMT Relocated the post regulator inline booster pump to a nifty location right by the transmission. :) Relocated the post regulator inline booster pump to a nifty location right by the transmission. :)

Test car is our 135i running 100% factory fuel system, E85, with an inline pump *after* the regulator to allow for higher than factory low fuel pressures. We're finding with the factory and modified high pressure pumps an inability to hold full pressure below 5500rpm at high torque levels when you push the system with certain combinations of high torque, a richer AFR targets, and 100% E85. I am hoping raising the lower inlet pressure is the answer. So far this is the only test I've done and the results were not entirely what I hoped for.

Quote:

I completed some initial inline pump testing this morning. The factory low pressure sensor tilts at 87psi so I had to plumb in a mechanical gauge to monitor low pressure. You can see in the video normal fuel pressure is 70psi. Then when I click the aux pump on it jumps up to 140psi at idle. I then pull on to the track and do a short 2-3-4 run and you'll see low fuel pressure hover around 100psi.

This log is from that same video above and summarizes what I'm seeing with this. During steady single gear runs it seems to hold high pressure as well as if not better than the normal in tank Walbro @ 70psi. But during sudden load changes (like shifts) high pressure is still crapping out even with 100psi of low pressure behind it. Although it does quickly recover. Maybe a surge tank is needed? I'll have to mull over the data some more on this one.

There is no secret that the oil coolers on the market current are extremely overpriced (BMW tax much?), $800 minimum for essentially a few hoses and fittings with a radiator is crazy. We are looking to put a kit together in the next few weeks, we will log oil temps on the current setup (currently equipped with BMS Low temp thermostat) and with the custom kit and post logs to show cooling improvements. In addition we are looking into a AT transmission cooler as well, we will look into this more when Garth has my car next week and installs my Nitrous Express kit.

I need a little help/advice on doing so,... Hey all,

As of right now I am looking at upgrading the cooling systems of my car, a FBO 335i AT 2008. I need a little help/advice on doing so, however.

First off, let me start by saying that I have the stock oil cooler from the factory with the stock thermostat, as well as the Helix FMIC to control IAT's. I also have the aFe sealed intake box. I live in South Florida, where I see 240-250 oil temps all the time, and this is higher than I would like to be operating at. Ideally, I would like to be around 210-220 on the street, and during a track session, no higher than 250. This brings me to my options I have researched thus far with a budget of around 1,000 dollars or less:

AR Design Oil cooler-- I like how it retains the stock oil cooler, and I can use BMS's thermostat delete with this. Problem with this option is I was reading Alpina B3 Lux's review on this product, and apparently the core blocks about half of the stock intake snorkel, which is the primary area I get my air from. Also, being an AT, I need to keep as much rad surface area as possible to avoid higher coolant temps than I would like. I know airflow can pass through AR's core and into the rad, but it seems like that may be less than ideal? SO far, this seems to be the best option, as I have also considered doing the PPK rad retrofit (more on that later)

STETT Stage 2-- Looks as if it replaces the stock core. I don't know if I want to go this route if it costs more than AR's kit, and essentially has less overall surface area than the stock+AR combo. I like the fact that it uses a 180F thermostat, as it will allow for proper oil warm up procedure. I also like how it dousn't interfere with the radiator at all. I know some users have experienced line leakage problems, but it seems as if aftermarket steel lines solve the problem (I don't think this should be required from a kit the price STETT charges)

ER Sport Oil Cooler (Competition out of my price range)-- Not sure how good of an upgrade this will be for me, if I already have the stock OC. If it keeps me around 210-230 on the street and dousn't pass that, I would be interested however.

As of right now I am leaning towards going with AR's kit, but I would like to hear some of your experiences with various OC options, and how your temps look on the street and road course. These options mentioned above are the top three I have come to in my research on this topic, but I would like to see if anybody has had sucess with other kits. I am not a DIY person, I would prefer a kit specifically made for the car I can purchase and hook up right away. I was also looking into the PPK aux radiator option, considering I could do this as a secondary option, and live with a thermostat delete on my stock oil cooler for now if this PPK rad really helps coolant temps. In the end, I am wanting to solve both heat from coolant and oil, but will do which ever will net me more of a benefit in the mean time. Has anyone here retrofitted the PPK radiator without buying the PPK tune (As I am on COBB)? If so, what were the part #'s/final costs?

Thank you for your time, I am looking foward to hearing your opinions on my choices and/or PPK aux radiator thoughts as I know AT guys need to worry about coolant temps more so than MT guys. Also on my to do list is the M-Tech front bumper, to get more frontal surface area to benefit airflow to these various cores.

I am guessing this turbo has to be removed to be fixed...I will contact Rob on how to even fix this.....these only have 4,000 miles on them. Has anybody else ever had this happen?
