third gear pull. i don’t see timing drops throughout the RPM range however i am wondering why cylinder five and six sit at zero for the pull. everything else looks fine. input appreciated thanks !

car set up:

f series(PWG) FBO pure stage 2 , 93 fuel
map 6 targeting 15.5 psi
stock fuel system

thanks

running jb4 map6 with “race” MHD BEF from terry

[Payam @ BMS]

I wouldn't run a race BEF with 93 octane, you need ethanol blend or some sort of race gas. That's more than likely for the timing drops, even for this short run.

[Marlinman]

Thanks Payam, maybe bad gas then?

I took this from the MHD BEF F series sticky:
PUMP: Intended for low grade fuels.
RACE: Intended for use on pump fuels and E85 mixtures up to 50%.
E85: Intended for use on heavy E85 mixtures of 30-100%. Note the N55 generally has a hard time supporting more than 30-40% E85 due to a weak high pressure fuel pump. If your fuel pressure is crashing you know you need to reduce the E85 mixture, reduce boost, or add in WMI or port injection.

so maybe I'm confused as to why one can't use RACE with 93, most of us F series with upgraded turbo and stock fuel are using RACE....

I've also seen these cylinders be just fine, hovering around 4-5 on fourth gear pulls but third gear pulls it feels fine but the log just looks as if they start and end at 0.....

i don’t know why but this looks better to me. all i did was changed target to 15

Can’t really tell much with these logs- not long enough WOT to determine much s

Lowering boost may help, but these flashes are too aggressive without higher octane. Still as Dave said, too short of runs.

[Marlinman]

I don't see a PWG pump option in the BEFs for F series....how can I proceed

[Marlinman]

Maybe I need a lower timing map?

Here is a full pull in map 5....thanks again for your input Dave and Payam. Please advise

I scrolled for quite some time & only saw a blip of you going WOT..

Proper logging to evaluate- 3rd gear, 2k to redline, WOT (pedal 100%), traction control off.

[Marlinman]

Hey Dave, thanks yep I have from 2K to about 6.5K WOT in there...I did have it logging for a bit but definitely thought I had enough data points. DTC was off as well and I was in third.

I’ll have to scroll & try to find it when I’m in front of my desktop - sit tight

For future try & make the logs as precise as possible, just makes it easier for use, versus having to scroll thru 100s of cells- no biggie

[Marlinman]

I got ya Dave, thanks. Also I should have told you guys some of my user settings too.

I'm on the PWG ISO most current fw with the BMS BEF via MHD (PWG) - FBO with PS2

default wg = 80
PID gain = 25
ASBR = 30
FF/Wastegate adap = 85
FOL 70
I've also got the third gear limit to 18 PSI

FUD 192 (slow CANBUS enabled and BEF enabled)

For F series PWG I'd suggest switching back to integrated. You can resolder the diode or get a V2 board from us and we'll refund half for you when V1 board gets back. The V2s all ship as integrated with the diode.

Thanks Terry, so the flash option isn't too aggressive? Or it is?

Based On what i see- id get the new board & then we can get a bit
More aggressive.
