More METH???

[Msport335]

i'm FBO plus inlets running all out stock turbo e60 tune with AEM meth kit (1000cc nozzle) with 60/40 meth/water (measured by weight). controller is set to start spraying at 7.5psi and fully spraying at 18psi

has a slight hiccup mid pull but no codes thrown...... question is do i need more meth ? when i ran a 50/50 mix, there was no misfire and hpfp looked a little stronger

HPFP seems to dip pretty low

track day is friday night and need to get this sorted out so i can finally get well into the 11's with the drag radials/meth etc

can anyone tell me if this is a failing hpfp or injectors?

Rail pressure dips like that, when you go WOT.

What about this one i logged this morning .....rail pressure stays low and bank1 stft spike rich

check your chargepipe, maybe the meth nozzle is not deep enough in.

[Msport335]

it's all the way in without over tightening

Check your HP fuel sensor ....

Looks like poor distribution of WMI. Take a pic of your set up. With the negative bank 2 trims the dme probably isnt going to raise the HPFP. Take a log with less boost and no WMI. Your better off evaluating 1 system at a time.

Here is a previous log of the same map running the 1000cc nozzle rather than the 500cc. HPFP recovers much faster ....had no misfires in any of these logs

its an AEM v2 meth kit ...single nozzle in a single bung ER charge pipe...pretty simple setup. maybe the AEM nozzles dont atomize as well as the CM nozzles which i have not tried yet

below are a couple logs from the same revision...same 1000cc nozzle only difference is its running 50/50 wmi

just had my HPFP and injectors all replaced by dealer last week.

tried running the 500cc nozzle and 60% meth with the e60 kill map and got the misfires again due to the hpfp dipping too low

today put in the 1000cc nozzle and 80% meth and no more misfire , hpfp doesn't dip as low either ...however STFT's get pretty negative towards high rpm.

so question is do i run pure meth and ramp in the progressive controller at a slower rate so trims don't run so negative, or keep as is, or try a nozzle in between like a cm10?

any cautions to the trims being so negative in the upper rpm range?

controller in these logs is set to 8 to start -12psi full spray
