5700 is really high, in my opinion. I see full boost sooner than that on my s366. Also, that's an interesting way to setup your boost solenoid settings. Have you tried high duty cycle values up to your target boost value? I don't have my most recent map (I'm on my work computer), but here is a screen shot of my relatively recent boost solenoid settings:



As indi00 mentioned, the boost target comp and WG base duty work together; as you can see from the pic, I'm not using boost target comp at all currently.

 

this is more of 6 of one, half dozen of other. your boost error table hardly changes anything based on boost target, so you are juicing it up in the lower loads of boost with duty cycle. but the boost error table can juice it to if set up to do that. basically more then one way to skin a cat here.

 

^True. However, using the boost target comp table will get you dialed in quicker (because boost correction is a function of boost level (2D table) whereas the wg base duty has duty cycle as a function of both load and rpm (3D)).

Regarding the boost error duty table, be sure to check your boost error FB settings. I believe the defaults are 0.4 and -0.4, respectively. Meaning, it doesn't matter what you have on that map (boost error duty) if your feedback settings are set so low. I suggest changing those values (if you haven't already) to match the settings on your boost error duty table (+10 and -5, to use my map as an example).

 

Ok I'll have to try things.

So is it possible to have it fully spool earlier in the Rev range? Roughly how far would it drop if settings are correct?

Would I get an increase in power in mid range?

Thanks

 

You made those numbers on the ptuning kit with a gtx30r? I didn't think the 30r can run that much boost or make that much power . What injectors and fuel pump?

 

Yes it is possible. On your setup at 15psi target, you have the wastegate at 54.6% duty cycle throughout your map. Your waste gate error duty is +10%. This set up is not ideal as the WG duty cycle using the Boost error table is roughly (54.6% + 10% = 64.6%) or however AEM uses the table to calculate. So at 0 psi, your waste gate duty is say 64.6%. The wastegate is closed at the start of your boost, but as you get approach 19psi, your wastegate is partially open due to the force of the exhaust gas against the wastegate, slowing down your peak spool.



The idea here is to have your wategate closed 100% right until your reach your target boost and then it cracks open holding boost to redline. As you can see, the 3 port boost solenoid is not efficient at holding the wastegate 100% closed.


The easiest way to set up the boost table is to see herecomesboost'a Boost WG Base duty table. From 0-11.5psi, the wastegate is assumed to be 100% shut. Then from 11.5 to 14psi, the duty cycle gradually decrease from 85.2% to 34.4% where at 34.4% duty cycle results in holding 14-15psi to red line. Boost target % window must be 0.

Then to boost by gear, you can use the boost target comp % to subtract the duty cycle from the Boost WG Base duty for the target boost. Basically, your max boost will have a boost target of comp % = 0. Say to boost 10psi, you set the boost target comp% at 10psi to -60%. Based off herecomesboost map, 85.2 - 60 = 25.2% duty cycle. This way, you can easily set up max boost and then subtract the duty cycles for boost by speed, gear or rpm.

 

This is on E85 daily driven. E85 allows for high ignition timing and boost without detonation. My knock voltage spiks < 1.5 at 18ignition timing at 25-30psi. Compared to 91oct gas I was able to run at 9ign timing @ 17psi.

FID2000cc injectors. FBM340 pump.

Going to install the Duel AEM 320L E85 pump on the SOS dual pump carrier when SOS releases their product. Getting some leaning up top.

Think I'm at the limit of the system. Notice how hp flattens at 600whp.

 

Awesome info in here. Thank you to all of you for the input.

 

Added this thread to the one stop AEM Thread we have.
