    Bit cleaner than before. Click here to enlarge Only one clamp is attached as I only had one metric bolt to fit that location. The 135i has two threaded holes right there for some reason. Perfect for mounting a pump. Click here to enlarge

    what about the LP sensor and DME compensating voltage to the in tank pump... will you add a bias? I guess this is the first test to see what happens.

    Based on the first set I learned the sensor tilts out at 87psi, throws a shadow 29F3 code, and the pump then switches over to a default duty cycle curve that is basically 100% duty at full throttle. So for now I won't bother with it. I'm going to program the JB4 to kick the pump on at 100% duty cycle at 12psi and see how it does in general compared to the Walbro in tank.

    You can also unplug the lpfp sensor entirely making the lpfp run at full duty all the time

    Terry are you saying that the 135i has two threaded holes by the tranny where you mounted this one on the 335i?

    Basically same thing. It actually doesn't run full duty full time though. I made a video a long time ago, let me see if I can find it...

    Found it. lol @ old CMGS. Click here to enlarge

    The 135i happens to have two bolts there to accept a pump bracket. I can't say whether the 335i has the same bolts.

    Busy day. Broke down twice driving around due to a fuel line popping off. First time luckily close to the office and second time luckily close to home. So I was able to walk a bit, grab tools/jack, and repair both times. Finally took it apart at home again and realized there was an assembly flaw. The quick connect fitting I was using to mate to the OEM line was not long enough. Found a FRAM F65217 fuel filter at Pep Boys and used that as a joiner. Seems solid now and so far so good. Back in business. Click here to enlarge

    The pump is controlled by the JB4 and turns on at ~8psi. When it kicks on map goes to 20 in the log, and low fuel pressure tilts at 87psi. Based on the last round of testing I'm guessing fuel pressure is around 100psi.

    Still slowly building confidence up with the install so didn't venture too far from home tonight but I did grab a few short logs. I can see PWM is maxing out around 60% even when fuel pressure dives. That must just be the maximum. I noticed a bit of inconsistency in how/when it drops. So I'll try to narrow it down so I have a good repeatable test, and then I'll program the JB4 to add a bit of duty cycle to the mass control valve in a situation where fuel pressure has been dropping just to see what happens.

    It's working at least as well as a single or dual in tank pump. But I still can't tell if its working better as I didn't get a good 100% E85 log on the factory turbos with the in tank pump and I'm too lazy to put it back in. Here is a log I just did, straight E85, map 7, on our E85 (leaner) flash. Fuel pressure dips at the shift but doesn't tank. But note IAT is > 100 degrees. When it cools down tonight or this weekend I'll do the same run with a 60-70 degree IAT so we can see where it really stands. I expect it will tank then. Click here to enlarge

    As next steps I have the Vargas fuel rail to install. And will be doing their pump. But I'm out of fuel system ideas at the moment. Unless some legitimate fuel pump company starts making a new pump (not upgrading the factory) I don't think we'll be able to get away from meth for fueling help.

    What % from minimum desirable are you theorizing we're at now re fuel mass for pump gas and E85 and where are the problem RPMs with the stock pump (and no help from meth or lean flashes)? I ask because I don't know if anyone has tried to pin some ballpark numbers these points.

    thx

    i'm confused... you have been doing all this on the stock pump? i thought you were doing it on the upgraded one.. what's the point of doing it on a pump we already know can't do 100% E85 in just about any decent power situation?

    will be interesting to see if the upgrade helps, you had me more worried that the upgraded pump +LPFP pressure still failed haha
