Last ESS Dyno

[LBC870]

Ok today I went back to the Dyno dynamics for pulls on program 3 with no plus or minus as requested. See below graph. These are the last Dyno pulls I'll do for a few weeks. I'll post the program 2 + 2 and +3 with race fuel in the next post. iPhone will only let me add one picture.

Program 3 no plus or minus

Program 2 +3 with race fuel. Still dropping off at 6600, even miss fire. Something isn't right, only 1 hp gain with race fuel.

Program 3 fuel is red
Program 2 +3 is blue.

Blue is adding a lot of fuel.

There's generally always going to be a big dip for factory turbo cars. The turbos cannot flow enough air at the higher RPMs when more boost is added. Going to need bigger turbos to pick up the top end, but you'll lose a little on the low-end.

Not to thread jack but your M looks so sick in that picture.
Seen it on instagram

So doesn't thst confirm my point? Curves look much better holding to near 7k which for this car tuned is right.

[8600RPM]

I guess holding to 6700 or so. With a decent tune . Looks much better than other ones. Was it done with race fuel? The program 3 with no plus or minus?

Drive it long enough to adapt?

That's the best curve you'll get with tune on this car if you want that much power. I prefer less power but holding power to 7500.

Try program 1 and see how you like that

My guess is you were running tune too aggressive, timing was being pulled badly. How do you know a misfire occured?

Haha - thanks man!

THIS is the best (for my driving interests) ESS piggy curve I've seen to date. Please say it was done on straight 93-octane and not race gas???

Mine just arrived FEDEX today and will be going on next week. After seeing this, I plan to start with program 3 no +/-.

Program 3 was with 93 octane.

Program 3 on race gas would look really good

Are all you folks spending the time & money to pursuit dyno results mixing $10/gallon race gas drag racers? Or are people actually daily driving these cars with race gas? We all know a high-octane tune can capture additional power over pump, but if you're not gonna run the car that way...who cares?

Please understand, I'm not meaning to flame anyone at all...just trying to understand the constant reference to octane boosting going on.

[8600RPM]

Because engine pulls timing at stock boost let alone tuned boost on 93 after hard pulls. Look at n54 site logs. Same with many modern cars.

Program 2 +3 is a beast as you see but once you reach 6600 it starts to sputter for a split second then smoothes out. That's what I meant by miss fire. What do you think it could be? What I don't get is the hardly any change with race fuel. Torque is about the same and 1 HP only from the first Dyno I posted the other day.

Make sure between map switching you are allowing the car to adapt a bit before dyno pulls. Anytime the car hesitates under load it is usually due to fuel. If you have given it enough time to adapt and you are still getting any hesitation at high RPM increase the mix of race fuel or go down 1 setting in the + - until the vehicle performs correctly.

Race gas is 7.50 out of pump near me vs 2.75. I drive a tank a week so ends up being about 60 bucks more a week. Running a tune in hto weather it's a drop in bucket to get max performance and eliminate timing being pulled

In AZ I believe you're limited to 91-oct out of the pump? We have 93 here in NY (and cooler weather), so I'll be curios to see how the ESS tune behaves relative to all the Dynos I've seen and reviews I've read on 91 from you guys out west. Curious how (and how long) the car needs to be driven to adapt to new tune?

[8600RPM]

If I had 93 good gas I wouldn't be so inclined but 91 is just crap when temps hit 100 and I logged timing on my e92 and in summer with 91 it was way timing retarded and down on power. I can only imagine this engine. I drive hard too so it's not like I'm baying it. I thrash it to redline every drive often. I'd like to get some dynos but Wil log data with jb4

All of my Dynos this week have been either 93 or 100.

Yup...and it's the graph you pasted in post #2 above (on 93-oct in program 3 no +/-) that I'm planning to start with. To my interests, I think the curves are near perfect. Thanks.

Charts look good for a DD, be sure to allow a a few runs in between for adaptation to full set in.

How's it feel on the street?
