There's really little to no risk of blowing anything up when adjusting user adjustables. The ranges are limited to what is reasonable and safe. Just avoid the obvious things like running a stg 4+ map on a stock car while running 87 octane.

A highway/road trip map would be cool too. Less power, but everything focused on improved gas mileage while cruising.

[Ilma]

So here is the datalog of the OP's settings:

Procede stage 2 on a stock car (only DCI)
User Torque set to 45%
Ignition Correction set to 0% (therefore stock timing advance with no correction by Procede)


3rd gear pull into 4th gear for a bit.....Looks nice and smoooooooth......feels that way on the road too.

Peak boost of 11.3 and peak timing advance of 11 degrees with no dips or timing spikes at all. Notice how the ignition correction stays at zero for the duration of the WOT.

Like Fotios stated. It's a nice daily driver map for those who still want some zip, but don't always want to be running boost levels too much higher than what BMW has tuned for the 335is version.

IMHO this map would be much safer than even the default settings for the Procede

So I think the warnings being expressed in this thread are kind of misplaced and should only apply to those going with higher than default settings, OR running maps that are beyond their modifications.

But that's what datalogging is for

looks like a ~4deg drop in timing right before 4 secs - no?

I'd run some ignition correction personally. Even just 30-40% should make timing even more stable.

Yes....you will often notice the DME adjusting power during the Vanos changeover between 4-5K.

I think the thing to notice is how high the timing advance still remains after the adjustment (7.5 degrees) and that it continues on an upward sloping curve to hit 11 degrees.

It's dropping from a peak of 13.5 degrees as boost ramps up to hit the 10 psi mark.

13.5 is too much advance for the higher power levels especially at 4K rpm.

Ignition should advance upwards to hit a peak of around 10-11 degrees close to redline.

Will give that a try and see what happens

Seems like my car is really eager to advance timing too soon in the powerband which is why I almost always see that adjustment around 4K.

You often see the same type of dip on the dyno charts around that same rpm.....so it's not uncommon and seems to coincide with the Vanos changeover.

At least that's what the tuners have been saying

Another question - if peak boost is just over 11 psi, what's the benefit to running stg 2 at 45% UT vs running stg1 at 75%(my guess) UT?

What would the UT% be for stg2 to = stg1, or is there more going on in the maps?

I cant see a benefit, but if your running stage II at least your map 2 can be full force when you want it.

if your a stage I car then run stage I

Yeah - that's what I always thought. I'm just trying to figure out how some cars with just DCI are running stg 2 with no problems.

Nice to know Shiv, but IMO you can never have too much of a safety margin. You should add some safety measure to idiot proof even the 4+ map such that if things get hairy, just bog it. All it takes is one blown engine, for the PROCede done it finger pointing to start. I doubt the culprit would even admit he f-ed up. Even if you are supposed to use common sense, I still prefer to know you can't exceed the limits by simply absent mindedly picking the wrong maps and then getting on it.

Victims sue gun manufacturers all the time even when the person behind the gun is really responsible knowing what it can do. Think about that. I know Bimmerfiles supposed to enthusiasts who take care of their vehicles and all, but we have our fair share of idiots too is all I am saying.

Hi Ilma,
I should have been more specific. I wasn't referring to the timing reduction at ~4300rpm. That's a pretty common retard even due to all the valve timing changes that goes on at that point. Trying to tune it completely by applying global ignition correction trims out will mean castrating the rest of the tune as you've seen before. I was actually referring to the timing reduction right after the shift (around 6.5 seconds). You can see that DME timing drops to 7ish when it would like to stay at 10ish up until higher RPM and, after that, ramp up to 13.5 deg by 7000rpm.

I don't think those dci cars are in Florida or Texas are they? It matters where you are too as weather does play a factor into everything. Folks in Canadian North East for example can run almost anything they want for most of the year I think?

temp, mods, and octane are huge deciding factors on what the car will like

Which is why we are making the custom tuning process automatic. No use doing something manually (datalogging and looking for ignition advance drop outs) when a computer can do it for you, all the time, in real-time.

Ahhh......gotcha!

I will try that on the way home tonight.

thanks for pointing out what to look for.

Hmmmm, now we are talking!! Set the right map stage, and let the PROCede do its work! I like that very much. It would help if we can have map1 stage 1 map2 stage 2 for example then. So those guys who are stage 2 but rather run something mild for DD can set stage 1 as default and double click to kill the civic taunting them at the traffic lights.

I would like to see some people do multiple runs with this low Ign corr and low UT. Lowering the UT should result in less heat but lowering the Ign corr should produce more heat. I am curious to see if it heats soaks or not, like the high boost setting sometimes does on my car. If not I would run this way just for the infinitely reproducible power with no cooling off period after a few WOT runs.

Ummm...love it, so when do we get it?!?! I know, I know patience grasshopper, but what you did is like putting a filet mignon in front of a tiger...I want it now!!

Thanks Shiv, keep it coming...lovin V4 and it keeps getting better!! Spring is coming, which means the itch to start doing more, 2-23 maps are great, I think some DP's are in my near future and maybe H2O+Meth, but we will see.

Cheers

[rbaldwin28]

I ran this today and I feel significantly more power over 4000rpm. The stage 2+ map (Default) fells like much more torque but only before 4000rpm. After that it feels as if it stops pulling as hard. It seems like if I can run 0 ign corr on 40% UT then I should be able to run like 50 ign corr when on 100% Ut. I am going to try this and then data log to see if it is as peppy up top. I think I am going to need to data log on the dyno to really fig this all out.

I run mine around San Diego stage 2 with 0 problems so far. I have Exhaust but my downpipes are stock so I don't think that helps much.
