Here is a log using the PS2 OTS map with 93 octane and stock fueling:

Log looks good, but not the best timing. I'd try the 91 map to compare. 16-17psi really is on the edge of what 93 can support for octane - again IAT dependent.

Looks perfect with the XDI but stock is rubbish.

Would have been good to see how the B58 pumps in the above comparison.

Agreed!! Which is the reason I'm on the fence about using the B58 pump to utilize the PS2 OTS map OR get the XDI-35 to eventually run more boost or E40!!

B58 = $350 VS. XDI-35 = $2000


Decisions.....Decisions!!

What spark plugs are u using?

OEM plugs that came with the car and most likely have never been changed, going on 51k miles so far. But I'm going to be swapping them out before summer officially hits here in Florida!!

Car felt great but rail pressure just drops after 5000rpms!!

Here is a custom map log that im currently running:

I know MHD does and would think BM3 does as well....

I have written to BM3 and they responded that they don't have PS2 OTS map for EWG.. They probably have a Stage 2H OTS map for PWG PS2.

Oh damn that sucks!

I know MHD has OTS maps for the EWG PS2 and are currently developing PWG PS2 OTS maps.

You might be better off getting a custom tune to use the PS2 on BM3 OR run the OTS maps until you've finished your build.

[T_H_O_M_A_S]

today some more testing with beta PWG PS2 OTS maps from MHD .
i'll post both logs later on so you can compare between custom and ots .
pls do know its in development fase

[punisher12b]

are you gonna run stage 2 with pump fuel on your b58? alone

[T_H_O_M_A_S]

MHD OTS Beta for ps2

https://datazap.me/u/thomas/log-1556...og=1&data=4-21

My custom wedge tune

https://datazap.me/u/thomas/log-1556...og=0&data=4-21

both have two logs , full and partial throttle


and yes i'm currently on 93pump and B58 hpfp

you hit 22 psi the pressure looked good too, I cant wait to do the ps2... I will be using bootmod3 though as I am already down that road

Logs look good with B58 fuel pump. Even with the Wedge tune pushing the boost up it seems to hold well .....


https://datazap.me/u/mattspies/log-1...8;zoom=101-202

My log is E20 with stock Fuel pump... i love a good looking log... i think

[punisher12b]

I will be using BM3 Cary Jordan is looking into this as an option now as well.. I hope by the time im ready to do a custom tune ...the b58 will have proven yay or nay.. its starting to look like it is though. as a mild upgrade

[T_H_O_M_A_S]

in a few days i will test with 10 percent toluene ( oct 115 )

to see what timings will do

i cant do e20 with b58 pump , tried it , but pressure dives quickly
for ps2 and e20 i need xdi for sure

What boost were you pushing with E20

[T_H_O_M_A_S]

around 18 also , but never got there in the first place
b58 is only a little bit better compared to stock hpfp

Im stock turbo and am hoping for 18psi with maybe upto E40.

check the n54tech topic ( n55 section ), theres a guy who maxed his stock turbo on an M2
it was either e30 or e40 he ran

[punisher12b]

what are current updates any tuners care to join in?

On E20 your logs show you are at 15.6-16psi.

Going to E40 and expecting 18psi is a big ask based on yr current set up - what changes are you going to make to get the most out of E40 blend ?

Main thing i was changing to b58 hpfp with a custom tune...
In saying that ive done a deal on a M2C and within a week my car will be gone

[punisher12b]

looking at some logs and some XDI logs.. thought.. it appears that the rail pressure could have a few hundred PSI sustained.. and while we know a PS2 turbo can run on stock fueling seems like it is a possible small bump for those not wanting to go nuts ( got my ps2 cause i had to warranty out my stock turbo )
