Did a virtual dyno today in 3rd gear just for the hell of it. Running at 7psi does this look right? Specs in my sig

Are you dropping boost, or maybe spiking before you level out? WHP dives towards redline, no reason it shouldn't be climbing all the way to redline with your setup.

FowlerMotorsports 08-19-2012 08:31 PM

I think I may be spiking out, boost gauge reads 7psi until I shift gears. The car seems to rev fine til 7000rpms then bogs a little bit, I am still under the learning phase of tuning.

Your fuel tune definitely needs work. I think your drop-off in HP is coming from going super-rich at the end (below 10:1). I'm home now. Let's try to get together and get that fuel sorted out. It's darn easy.

That said, torque is looking good for 7psi (170 ft-lbs). Your HP will pick right up when we level out your AFR.

FowlerMotorsports 08-19-2012 10:11 PM

That was my main thought. The AFR does look a bit wobbly and where my HP drops is right when I get rich as you stated.

Car pulls very well, I will give you a shot in the drivers seat if you're interested. You don't notice any power loss after 5k when driving, but maybe I will notice a change once a few tables are fixed. Your house is right down the road from my work, I will swing by when you're available one night or even this weekend.

I'm jelly of the nickel 6uls, or any 6ul at that...

Fowler, could you please upload your tune? I'd like to check something out

where is your boost measured? before or after the intercooler?

It Ts off to my megasquirt, should it be routed elsewhere?

Buffon, tune is attached

Is that with the basemap I included or did you do any autotuning? Nice to see it run!

FowlerMotorsports 08-20-2012 09:55 AM

It is your basemap Autotuned. I was running a little to rich so figured I would just autotune to get a decent tune going

sixshooter 08-20-2012 10:01 AM

Needs a little richness in the middle and a little less up top. What are your target AFRs?

FowlerMotorsports 08-20-2012 10:22 AM

You got me, i'm not sure what I should be aiming for on a FI car

I was just wondering if this might have been your problem with the drop in power up top.

can't powdercoat 6uls

FowlerMotorsports 08-20-2012 02:31 PM

then i'll paint them, i'm not worried about it

I'm probably the worst MS tuner on here so for gods sake don't copy my stuff cause who knows if its right, Ive just copied other peoples stuff and tweaked it to my car. Anyways with that said I noticed a couple things with your tables. Your afr table only goes to 100kpa (roughly 0 boost) and ramps like crazy (12.5@70kpa across the board), at this rate you'll be running 12.5 cruising on the highway and low 13s at idle. Anyways, heres what my tables look like, (me on top;)) and heres a good thread to check out for afr tables.

For the second picture I'm comparing the fueling tables in 3d view, you can kinda see how yours looks like a canyon, the areas you've autotuned are ok but if you ever step out of a tuned area your gonna have crazy amounts of fuel

Hopefully this helps some. I dont know, hopefully somebody else can fill in with more technical knowledge on what I'm getting at.

EDIT:
Just out of curiosity do you have the .msl you used to make your virtual dyno?
