Default meth spraying & fuel trims..what to do? :) - 02-04-2020, 10:35 AM

Hey all

When spraying Ethanol/H2O (BMS kit map 3 CM10 nozzle)

fuel trims bottom out, because Im adding fuel, I know that

how do I correct for this?

when you get the BMS meth kit it dosent say anything about you would need a custom map for it to work so any tips on what to do would be great

I know the meth settings (adder etc) can be adjusted , would that be it?

(I dont know anything about adjusting fuel scalers etc)

The logs looks good from what I can tell. Trims are steady where they should be.

How are you spraying methanol, are you using the JB4 as the controller?

This is a Map 2 run so no ethanol/H2o spray here.

I tried doing a Map 3 run to show the trims going down, but as stated it did not store it for whatever reason...

Im using the JB4 with FSB

Okay, try and post a log on map 3 with methanol spraying.

I have a similar problem where my trims with Meth (800mi/min) will truly bottom out ie will go below zero depending on temp outside. My understanding is that as long as you are above 0 (-25 trim) then the ECU is still able to compensate by pulling enough fuel. To me the OP's trims look fine and this is a very conservative boost adder with meth and with that timing.

@Steve - I have typically changed my fuel scalars in the BMS race flash from 1.10 to as low as 1.00 to compensate for this but I'm not sure this is the best approach as all cylinders are less happy. I have considered in the past lowering the FOL below 40 (it never moves from 40 unless it's crazy cold out and will go to 41).
When you go below 40 is it true that this removes the ability of the ECU to bias the fuel pressure up/down? I may try taking my FOL down to 20 but I'm confused about the drawback of this.

Thanks

Im spraying Ethanol & H20 in the CP (single CM10). It doesn´t feel like there
is any difference between map 2 & 3.. I would just like to max out the stock
snails with out fking the engine
better timing & higher boost would be nice if possible..

My opinion is run the Race flash with meth and start going up 1psi with the boost adder on map 3 and monitor timing. For reference when I was FBO/meth 94 octane on stock turbos I ran a 7 adder with 12 degrees of timing at the track. The older race flashes had much more timing. They are very conservative now. You should be able to run 10 degrees at least but every car is different.

Definitely want to land on the RACE map, but maybe not there yet.
I had differences in my Trims as well.
May want to run dual CM5, opposing for better Meth distribution. It helped me.

In the end, I kept pulling effectively to 0 on my trims, so I went with Trebila.
Trims sit at 25 and I got 6 more PSI out of it.

Just my experience...

** Also - it's super important to ensure your BM Nozzle has the insert firmly screwed into place. My first 2 (of 3) were quite lose which resulted in stupid high flow, just squirting the opposing side of the CP. (I have videos on the form of the before and after - I would even bog the engine at times I was soaking it so much)

Trims look a little better, still touch into the 40s initially but drop back.

Which flash feels better?

Which flash feels better?
the Race feels slightly better, but not much... virtuel dyno says 379 whp for the race flash log , and 370 whp for the log with the pump flash.. seems a bit low..

Your bank 1 AFR looks very jumpy to me...this may be causing your big timing drop mid run. WGDC also looks strange the way it is climbing. My car has a pretty much flat WGDC - Stage 1's turbos but not that different than stock. Perhaps you have a boost leak. I reduced my FOL (only to 35) like Steve suggested you do but I need to take it down further as my trims are much lower than yours. I can post my most recent run if you would like for comparison (ran 3.35 to 60 - best ever)


335i FBO,Meth,JB4,Sutphin flash,LSD,GCLites 11.25@127.4 on NT05R

335xi FBO,Meth,JB4,Sutphin flash,VTT stage1 11.38 1/4 - 7.30 1/8th - 3.35 0 to 60 @ 0C
