Im up around 1600Hz at around 220 something load at 8psi. I cleared out all of my saved datalogs, otherwise Id post them up. I only get about 5 counts of knock at most, but Im running a bit richer than Id really like to be on the safe side (11.5:1 and topping off at 11.1:1 at redline).

The only issue I have now is idle, she sounds like I have aggressive cams, but Im only running the 3.0 cams. I think it has to something to do with the EGR system since my engine used to run at -20 vacuum, and now its at -15 most of the time at idle. I have zero vacuum leaks as well. Stock ROM ran much smoother than BM does.

To me it seems like 220 load is a really high load. :dunno:

Does it seem like you can go above 1600hz if you tried?

I'll try and get a good datalog and post it ip here in a day or two.

I'm sure you could if you pushed the boost up. I'll find out here soon after I get a really good break in on the new clutch. I want to run around 10-12psi as long as everything looks good.

that log looks pretty good. How does the car feel

It feels alright. I'm sorta aching for more power though. I am only seeing 5 psi, but I adjusted my AEM Tru-Boost to 7 so I'm not sure whats up.

I regularly see 300+ load on EVOs... ;)

Oh, I'm not doubting it's not possible, I just feel it's a bit high for his setup. A 74 with a smaller turbo and 8 psi would make me think he's still AT LEAST <200. Especially since I'm maxing out the MAF and only at 140 load, while he's around 1600 hz and at 220 load. :dunno:

So what's next after the MAF is maxed?

thats just what I was wondering, your MAF is clearly maxed out. Theres a way around it i'm sure. What happens if you change the last cell in the MAF table to a higher number?
I see here http://forums.evolutionm.net/evo-x-engine-management-tuning-forums/555930-3-5-maf-scaling-table.html that the evox guys can change more voltage numbers and all on their MAF, can we access that. My method corrects the calculation for a givin hz airflow. However we want the given hz to be at a phyiscally higher airflow (not calculated)

Also by looking at this http://www.ecmtuning.com/wiki/maffrequencylimits i want to try something.
Make that same pull again, but add like 40 percent to your highest (physically lowest on the chart) maf values. add the same % to both sides, and run that log again, lets see if the hz changes, or if something silly happens. Obviously if the car starts acting bad (beyond a wierd AFR) then stop and clearly it didn't work

The 1st article is about the EvoX doing a bigger MAF swap.

Reading the 2nd article doesn't make me think we are going to max out this MAF with what little boost
we are running. I need to unfuck my laptop and get a few runs done.

I did figure out what my vacuum problem was, my egr valve would either be wide open or closed, nothing in between. Swapped in another one I had and it's back down to -19 to -20 now.

Yeah, I've read a couple threads regarding larger MAF housings and some about maf scaling.

Esp, what values did you want me to change? The "MAFLoadScale"? Or the Maf Clipping Coefficient? And why does that 2nd link say the max is 3000hz?
 
#1,494 · (Edited)
Exactly. The first article has a xml reference pertaining to different maf voltages, possibly lowering the hz per airmass instead of g/s per hz.
Change the values in maf scaling. Just add like 30 percent to the 16000 load cell as well as the accompaning g/s cell. Our ecu scaling stops at 1600 but 2g guys put our 501 maf in their car to read higher and theirs reads over 2k hz. My goal is to log hz higher then 1600 with just a supplimented g/s value to ballpark match. If that works we have to find the max hz for the 501.
Im pretty positive it will max out because at 5000 rpms at wot n/a im already pulling 1000 and up in hz and i plan for so much more. We just saw a maf possibly max out a.few posts ago

I'm actually missing my MAF Scaling table. It's written in my definition, but doesn't appear on ECUFlash. There's a couple other things that don't show up either.

Only Maf features I have right now are
-MAF Clipping
-MAF Load Scale
-MAF Sensor Filtering
-MAF Size

Set your user "whatever" to developer, might be able to see it then.

I've been through hell and back with my laptop. Hopefully it will work for me tonight on the way home so I can get a good log done. Car is running much better now with the other EGR valve installed.

Are you guys logging load calculated or raw load? You need to setup EVOScan properly to get an accurate load value and you need to have your injector scaling set in EVOScan.
