Finally got my 2016 R3R dyno'd with the AFR working!

[Speedy]

Engine intake systems and exhaust systems have different performance characteristics depending on the engine acceleration rate. So, a dyno pull at 300rpm/sec acceleration control will have a different AF curve than one pulled at 600rpm/sec as an example. Also, the ECU uses an enrichment algorithm that adds extra fuel depending on throttle position, current engine rpm and acceleration rate. Thus, the dip in the curve as the throttle was pulled wide open at 2,000 rpm. This is why some ECU use a gear position sensor and modify the fuel curves for each gear.

A pull in every gear will be different. And depending on the dyno type, the torque/hp curve will be different as well even if the AF curves are virtually identical for each pull.

You should see what negative acceleration rates do to AF curves!

Wow. In awe of all the expertise on here. Very interesting.

When I get out, I may end up getting some formal education to fill my gaps in knowledge on tuning and doing it, but I'm NEVER EVER FOR ANY AMOUNT OF MONEY EVER EVEN COME ZOMBIE APOCALYPSE MOVING TO THE EAST COAST OR SOUTH OR MIDWEST so....

What about Madrid? - Food's good!

 

[Claviger]

Madrid would certainly be viable .

Really though, when I buy my next house I'll probably look for a used 250i so I can do it as a side gig in my garage lol. They're certainly not cheap, but I think I can swing it. Cursory looking at used 250i models... can definitely do later once I retire

Then I can join the "dude in a shed" club, though, I'll be a lesser dude in a lesser shed than the original lmao.

Let me make it moreso. Wine is cheap.

And there are almost no braked Dynos here - You'd clean up. My mate has an inertial setup but he won't let me use the R3 on it in case I break his Dyno.
At the GP in Jerez guys come from Holland with dynos in vans - There's demand esp from the power ranger brigade.

I advise against SHED here - unless you like to bake alive at Sun Mark 8.

thanks everyone...I dropped her back off this morning and the tune is going to install my PC5 and do a custom tune today.

I will share results once she's done!

I was thinking you drive the truck, I'll ride, and we can trip to certain locations for a few days so you can service the boys . . .

I had to Google that 250i
Jeez your military retirement packages must be great, to afford one of these as WELL as a house!
Blacked out of course.

Do not forget to buy all the other stuff that goes with the dyno. Room, extraction fans, computers, respirator, etc etc. For the R3 also extra cooling fans, live torque module. Big engines make a bunch of heat when working. Go for it.
