Default Log review please: Pre to Post E85 BEF N54 - 05-11-2019, 04:46 PM

Hi guys,

Finally got around flashing my DME with E85 BEF so I did some logs before and after the flash.

It seems post flash my boost is bit less on target than previously. Any advise on what settings to adjust to bring it more on target?

Seems like FF may need to be raised a bit, and you might need even more duty bias at the top end then you have already. The curve seems to be maxed because it flattens out, might need some other advanced settings to tune it. However, PWM is maxed about 5500 RPM and up on the post-flash log, so there isn't anything left to give. Not sure why you needed so much more WGDC for the same boost level after the flash... Did anything else change?

The “post” log- was this the first pull after the flash?

Nah it wasn’t. Did drove it around for 15 mins and did couple full pulls before logging. Does it take bit longer to self adjust after flash than normally?

Imo logs tend to get a bit cleaner after a few WOT pulls and as you drive the car a bit.

Assuming u still have the flash on- how does the car feel?

Car feels great! Can definitely tell the difference all around. Lot smoother power generation even in moderate throttle. Close loop operation is much improved as well as in part throttle where I figure JB4 isn't doing much and letting DME do the heavy lifting

Best of both worlds imo.

We can get a little more aggressive if you wish

That’s pretty normal for stockers, especially if running stock inlets

Yah still on stock inlets as well, thought I "reamed" them out a little when I had the engine out.

Would silicone inlets make a huge difference in getting the boost on target at the top end? Just wondering if they are worth the hassle of install

Inlets would help, but the stock turbos can only do “so much” - would it make things more efficient, yes- but you’d still be pushing things pretty hard.

With the low cost of inlets, imo it’s worth it, but install can be a PITA
