    PTF Tuned E50 335xi Dyno Run

    I recently went to a dyno to see what my PTF E50 / 93 octane map is putting to the ground on my manual transmission 335xi. The only other modification is an AFE DCI. The plugs are new and I was walnut shelled a few months ago. The results are 413 whp & 448 wtq. This is massively impressive to me given the relatively huge delta over both stock (from what I gather, 280 whp/wtq on P&L Motorsportsí AWD dyno in Franklin Park, IL) and the 93 aggressive OTS Cobb map (356 whp & 389 wtq). As the below graph shows, a peak number comparison is just part of the story. The delta in the meat of the power curve is quite good.

    Tuning with PTF was a good experience. I would encourage those on the fence to pull the trigger because it is of great value, especially for those on ethanol blends like me. Jake at PTF was very responsive and was willing to make small customizations to suit my preferences in throttle feel and high-end timing. He took the time to answer all of my questions, which was valuable to an inquisitive person like me. Doing runs in 3rd gear and emailing them to PTF is pretty easy and you can take your time doing it. I started in September and didnít finish until December (holidays, business travel, having to get a DCI and getting married interfered with my tuning schedule). This flexibility was a huge plus.

    The map is smooth in all situations and drives predictably. From the graph, one can easily see why people say not to take 3rd gear and higher up to redline- the power falls off fast. Also, Jake was able to get rid of the 3rd to 4th gear shift knock / timing pulling. In fact, this was the reason I first reached out to Jake.

    Before I am asked, the dyno operator, sadly, did not log the runs properly, so I do not have the logs of these runs. So, do I earn my FlexFuel badge yet? Front-door parking for me at Whole Foods from now on!

    Blue is the PTF map and red is the Cobb Stg 1 aggressive map. Green was a failed attempt to show what a stock map with a DCI would do (not like I could drain the fuel tank, so it had to be a custom map). Boost was a pound or so too high and I didn't feel like monkeying around with it since the curve looked within expectations. Each run posted is the best of three with similar cool down times in between. IATs were similar between runs and higher than I'd like. Intercooler upgrades are key on this platform.

    Very nice results. What made you pick p&l motorsports for the dyno? Also p&l does have the ability to pro tune them selves. What did they say?

    Funny you should ask as I am trying to find the right place to post a P&L review!

    I picked them because I know them from my WRX days, they are near me and they have an AWD dyno at a reasonable price per hour. Again, I was just renting it for an hour and running PTF and Cobb maps.

    They just got their tuning software for BMWs a month ago. There is a guy who got tuned there by Junior and he posted his results somewhere in this forum.

    Great numbers for such few mods! Did you have a chance to log low side fuel pressure?

    I'm picking 135i this weekend with some bolt ons and Cobb AP. Mind if I PM you if I have any questions in regards to PTF tune? I'm local to Chicagoland.

    I see, Yeah I read the other guys review, I just have not heard very many good things about them and was just wondering how your experience was with them. Glad everything worked out and everyone is happy. Cya around

    E85 is some amazing stuff when properly tuned for it. PTF did a heck of a job with my E45 map.

    Great AWD numbers @vwgrk1...E85 indeed is a wonderful thing especially when direct injected

    What is the highest ethanol concentration PTF has done a tune for? Seems like almost everyone is doing E50, is that a fuel pump limitation?

    I will be doing the inline fuel pump so I can do E50, but my LPFP is kind of weak.

    We haven't seen much if any power added by going higher than E50...we've gone very close to pure E85 a couple times..E50 seems to be where its at for the moment

    Can you guys let me know if the dyno graph is showing up? I had posted this in another forum and people were saying that they could not see the graph.

    How is your clutch holding on with that much torque?

    Hey, sorry for the late reply. Been traveling for work. It's holding fine in daily driving, even spirited daily driving. That said, it's not like I'd be able to smell the clutch if I am moving fast and it is starting to slip in 3rd or 4th on a WOT run, so I can't be 100% sure. Plus, it hasn't been a huge number of miles with this much torque.

    The reason I ask, is that I have a similar setup and my clutch is slipping in high gears on WOT. I am thinking that 450wtq is the limit of a stock clutch.

    My stock clutch just started to slip in 5th, I'm approx, 440wtq maybe more. So far 3rd and 4th seem ok, just a matter of time before it starts slipping in those gears.

    Will you guys be replacing with a stock clutch or aftermarket? I like the stock feel and would rather keep it that way.

    replaced mine with Spec Steel SMFW and Stage3+ Clutch

    Works fine so far. I will load Cobb Stage2+ soon.
