SHOW ME YOUR TIMING ;)

[SlowE93]

I think your onto something I might play around with map 6 a little

On those turbos, generally speaking of course, every 1 psi added gives roughly 10 to 15 whp. So I say about 12whp average per psi given timing doesnt tank. If you added 1 psi across the board, you would gain torque and whp. Peak torque (depending on tuning and boost curve), is usually around 4k to 4800 or so. As I said, peak whp is 6k plus. So if you take map 3 boost curve and say 25 psi peaks at 5k then tapers, if you did a map 6 that continues 25psi from 5k up, for every 1psi you should gain 12whp GIVE OR TAKE and maintain whatever torque you are at now. Which map 3 I believe tapers 2 psi or maybe a little more from peak psi so you could stand to make roughly 25 whp PEAK as I said earlier.
Keep in mind, peak numbers dont mean TOO much overall.
Just looks good on paper.

mine goes from 9.5-12 degrees.
26.5psi target boost
65-70% wgdc
6AT with xHP s3

Fully built bottom end with stock head
8 deg max with zero corrections
25psi
65 to 70 wgdc
Double barrel shotgun, no pi or meth needed
on 93 with a little e to make e15
between 615 to 630 rwhp

Desensitized knock tables ?
I ask because the false knock issue on built motors.

 

[martymil]

nope, stock knock tables

Here is a log from today, I'm a believer of running the car the factory intended it to be as much as I can on the ecu side.

Here you go this is on 93 with a small splash of e85 to make e19 added to supress timing corrections, added a lilttle to much
e as even on e15 I don't have them.

When driving normally I get 300 miles out of the tank

I have stock knock tables and throttle maps as I like my M button to work on the steering wheel.

The VTT gc 2.0 also help a lot, my previous turbos would have lots of timing corrections as the egt's where through the roof, with
the GC"s the higher flowing exhaust turbo housings help getting rid of these exhaust gasses quicker and I have next to none or
tiny corrections now and then.

As you can see when everything is done properly the logs look pretty sweet.

Happy to find this. Getting a custom tune 93+meth (F-series PWG Pure Stg2) and thinking there must be a lot left on the table running 12.5* at 17psi.

Most recent Dyno. Iat correction tables are stock so it started to pull timing on the Dyno. Made 620 hp and 680 TQ.


Dyno run and pic of the graph.

I will go for this timing in my next map. Ken @ Wedge suggests this map for EU ppl who can source 100/102 Octane fuel.

Sounds legit to me.

Hey guys I haven't forgotten about this tread I just haven't been able to get a real good log.. I've very happy with the conversation it has started though! on 27ish psi I'm smoking the tires still. Definitely do to lots mo powa baby lol... But the PSS in the cold are just garbage. Once I get some r888r's on I'm confident I'll have barely any wheel spin in 3rd and deff not 4th like wtf lol

 

[SlowE93]

4+ years later and no 888s ?

 

[IQraceworks]

On my custom E40 tune with RB2's....at WOT I'm hitting 11deg of timing at 6500rmps and 25psi of boost. WGDC at 60%. No timing corrections.

Engine should be making close to 575-600hp....car went 10.90 at 128mph with a soft 2nd gear launch.

 

[Thunderstorm1250]

Here is another datapoint... GC 2.0 turbos. 600 rwhp on a 2010 135i with auto tranny. 9 deg timing at 26 psi boost at 6500 rpm. This is 93 + boostane + 100% CP meth with 2 12gph BMS nozzles

 

[Maroon_e90]

Anyone got any ideas on why I am running 7 gallons of e85 and the rest 93 octane and only able to get 5.5 degrees of timing before I start getting alot of corrections? This is on a single turbo build with DI / PI

Have you tested the E85 out of the pump? It can range anywhere from 50% up to 80%.

Yeah its e87 by me. Plus im seeing people running 7-8 on 93 how is this possible. My car hates timing. Is it ignition or vanos related? I have eldor coils with b58 plugs.

 

[ShocknAwe]

How much boost? I'm at 16-18 psi and ~20 tapering to 15+ deg timing. Pretty minimal corr like -2 depending on temp.

Maybe stock vanos/cams are culprit?

And here i thought 14*'s was aggressive

That's why you're slow.

 

[Maroon_e90]

My log is above but its 27 psi on single turbo 65mm. Im also x-drive Wondering if that could be causing false knock? its a built motor too. I am not using stock vanos.
