Also, I have a friend with an ewg and we both have kind off the same map6 setting and taper is the same after 5k. They both goes down not matter what, like .5 psi difference, which hes on e30 and I'm on e45 and my trim tapers 44 and his 47-49. Meaning we both need to lower the target at higher rpms.

Basically what we have been doing, lowering target and trying to keep the fueling efficient as its my biggest issue and bottleneck. Plus with crap winter fuel It made the a/f wonky as hell too. I am about to start working with Dzenno again since we have better fuel available again.

I don't want to stack flash/jb4 but in all honesty it was the best of both worlds when tuned perfectly and the jb4 made up a lot of issues with boost control and fuel pressure. But that brings a whole different set of issues. I just like running flash only and its super consistent.

I will also want go for a flash like bm3 but not for now as my jb4 is working good for my needs and just been FBO.

From the logs, how to know when my fuel system is crashing? AFR around 14.5 , FP_H from 14-18, FP_L around 130.

On N55 PWG/EWG FP_h anything above a 10 is what you want and is good but I'm not jb4 log expert by any means. The bm3 log gives you actual pressure values so it's easy. If it dips below 10 it's def crashing.

Start scaling back from that. It's what I'm doing at the moment.

My car doesn't like going above E35ish. Wish I could get up to E45.

Mine either. Usually PWG cars like more e85 but if I start running more than 3.5gallons it starts to act strange and my HPFP starts to sound like a typewriter.

My car is completely happy with 4 gallons of e85 and 8 gallons of 93 once the low fuel warning comes on. Anything above that and it starts to just shoot boost sporadically at WOT.

Yeah basically similar scenario here. My happy medium is 3.5 gal of e85.

I'm not sure why but I dont see or feel anything like you guys said. I was going to the track yesterday but the track was close, and I put 6 gal of e85 and 8 gal of 93 on Tuesdays. map2 and 5 runs good, Tried map7 and I was having the same pwm maxout after 5krpms with 48 trim so I tied then to jump on map6 to lower the boost taper and my trim is back to 41-44 and pwm back down a little.

I dont see anything else beside that on that e85 % and car pull strong, heck im having some traction control issues.

Ever since i had the lpfp recall done i can run e40 and still see hpfp above 14

Not sure but it is frustrating sometimes.

[yoandry]

I got my replaced last week too, but I never tried anything above e30 on the old one.

Here is data log I just did in map map6 testing process. As this is for me to see how the cars run I did it how I normally push the car from on 3k on 3rd to around 6k and below. Notice how the pwm start climbing after midrage. Also dont know why I always over boost at wot on all the maps. Let me know what do you think.

That looks pretty good. Your avg ign is staying really low, wish mine was like that. I have some map 5 logs where I'm running a little too much E85 for my car I think. The overboosting I was concerned with my logs as well and basically what I came upon is that since PWG is mechanical, the boost can't be too accurately controlled as EWG can be. I've seen EWG logs that the target and boost data are basically identical.

I think my HPFP is on borrowed time. Every car is different, my car just doesn't like the e85 as much as most PWG.

I think mine is as well. I was actually looking up a new one last week just to get an idea of pricing. I got one extra long crank a few weeks ago when I tried to push to start my car and it wouldn't turn over. I just took my foot of the clutch and tried again and it started up fine. Hopefully it doesn't leave me stranded.

They're not cheap by any means. I looked into getting an M235i HPFP as it has slightly better flow than the older PWG equipped cars. I know of someone running it on a 2013 335i without issues

[sicmadek]

In my case i wonder if running high boost is even worth it due to the climbing iat. If i ran map 2 the iat would hardly move and avg ign would stay at 0.

Really? That's interesting. Those cars are EWG as well right? I thought most of the EWG cars came with the weaker pumps.

I'm Not 100% but I'll ask Alex about it in detail. It's definitely on his PS2 N55 F30.
I know the EWG cars don't like e85 at all but the flow rate of the M235i HPFP is what I understood was a bit better due to the power increase etc.

Yeah map2 is not that aggressive that's why we run it with not issues. I wast targeting 11-12.5 psi with mppk on torque app, not to far from 14 on map 2.

Ok my mistake it wasn't out of an M235i but I guess he ordered it and it's a different part number but a newer style pump. And quote supposedly better flow but no raw data that it actually provides that....

Maybe just the newest revision of the PWG pump then. My car is an early 2012 build, which might mean I have a weaker/older pump stock.
