More Rob Beck turbo dyno numbers.........

[Malaka1]

Can someone help me post the graphs? I have 3 .drf files which I open in Winpep7 but how can I post a picture of what I see? I tried print screen but that just gets my wallpaper..

335i 6MT FBO
RB turbos
M10 nozzle using Boost Juice
100 octane

Best run Map3 70 additive
459rwhp and 482wtq

Run 1 was meth additive of 50.
422rwhp and 442wtq

What are your full boltons?

Email sent!
Full bolt on = BMS DCI, AA intercooler, AR downpipes, AE exhaust, ER chargepipe, Forge DV.. some other things I may have forgot.

I did pull off a 8.8 sec 60-130 time earlier but I did not have it set to write to card.. I will do some more testing later and try to improve on that.

[dzenno@PTF]

got them..you've basically got my setup with the exception of the AA intercooler...i think given map3 boost you're hitting the right power...what was your boost at 6k rpm? send me your jb4 log as well

[dzenno@PTF]

Here it is...what's your ambient there? .drf file says 83F...given the ambient temp it doesn't look like meth was doing much cooling there but your timing didn't back down...i think in cooler conditions with a higher meth mix you could pull off better numbers

[Malaka1]

Thanks Dzenno! Ambient temps were about 84 degrees.

Thanks Dzenno! Ambient temps were about 84 degrees.

If this was my tune I'd say you hit this power at 17.5-18psi as your peak hp rpm is basically in that range even though you ran a bit more boost down lower to pick up some nice 481wtq

Ya looking at it again it looks like you are right peak power was made at about 18psi..
I think with some 100% methanol and some adjustments made to the fuel settings I should see closer to 480rwhp.

[dzenno@PTF]

What were your jb4 fuel settings including fuel pressure?

Try 100% on the dyno for sure and try to make small changes as you go otherwise you'll never know what works and what doesn't on your own car..

[Malaka1]

Fuel settings and pressure were all left at normal values, what ever the 12/4 Alpha came set at.

[Terry@BMS]

Overall log looks decent. I'd expect another 20hp or so all else being equal but all dynos read a little different. And other factors like rim weight, etc, can have an effect.

One thing I notice is your maxing out your fuel trims down low. So we'll want to raise the FPMapping higher, and maybe run a higher meth mix and more of it. You are still using the Labonte controller right? See if you can set it to start meth flow at 8psi and be at 100% duty by 10psi.

[Malaka1]

Ok so should I set FPmapping to 95 or 100? And I will adjust my Labonte controller.

Try 100 and lets see what happens. Worst case is you throw a fuel pressure under target code. The open loop mapping is still a work in progress. Basically we want the DME to think its running as low a fuel pressure as possible without triggering the under target codes. So I'm playing around with the tuning on that end. Once I see the logs @ 100fpmapping with 12/4 I have something else I can send over.

when was your last plug change/oil change, and intake valve cleaning?

[DBFIU]

Timing is good, you could use more meth though.

[Malaka1]

when was your last plug change/oil change, and intake valve cleaning?

Changed plugs just before getting on the dyno, oil change 1 week ago. No valve cleaning yet

You will gain at least 10hp depending on the mileage. LM gained something like 11-12whp...

[LostMarine]

As did Mr.5

[carcars]

resistance that leads you? 18-15 ohm

I still like the curb of afr, I think it has always beenthe Achilles heel of the JB4

What are you using to clean the intake valves?

Well done.
