-= Ultimate Emanage Tuning Thread =-

[BlackStealth]

sleeper3000: Wow, I'm surprised you're still having those problems, I thought you resolved them a long time ago. I'm suspecting you may have a defective emanage unit because you should be able to run stage 1 without any side effects when emanage airflow correction map is set to 0%.

Boomslang hooks up other additional wires outside of my "stage 1", "stage 2", "stage 3" diagrams. Refer to my "stage 1" diagram and have only those basic wires installed, and disconnect those additional wires. To make boomslang modifications easy I used some quick connect/disconnect connectors as I found myself switch between stage 2.5 and stage 3 often, and disconnected other emanage features when I was hunting for a glitch I was having in stage 3.

At stage 1, the only thing being intercepted is airflow signal. With the airflow correction map set to 0% throughout and emanage configured correctly for a 6G72 engine, emanage should be completely transparent, if not it's defective.

Incidentally which software/firmware revision are you using?

The only thing I wish I had available is a stock AFR chart with RPMS and Boost(PSI) as the axis. It would make tuning more comfortable knowing precisely what AFR it should be a given RPM and Boost. WOT tuning and idle/cruise is easy, but the AFR in between is a bit in the gray area.

yeah i've noticed all the extra wires going to all the other sensors and i wasnt really sure what would happen because i had it wired for stage one but also i had the input channels wired up. so i could add fuel still and see timing. dunno if i could add timing. i didnt wanna try. so i dunno. but i had all the jumpers set right for sure. went threw it like 4 times just to make sure.

software and firmware are 2.16 (i know its got the timing bug but i wasnt worried about the timing in the data log.)

i was shooting for getting a data log run using these sensors

greddy pressure sensor
a/f meter
rpm
airflow
throttle
ignition timing
I/J INPUT DUTY CYCLE
I/J INPUT DURATION

this time i'm gonna start from scratch. i'm gonna hook it up at only stage 1. no extra sensors are gonna be wired in. except for the greddy pressure sensor and the a/f meter harness.

and i will be running the data log in the emanage and in the hand held halo so then you can see all the sensors being recorded and also knock sum. if i happen to run into some.

but yeah blackstealth i'm having the same problems as before. and also while trying to get a stock datalog for you guys, my vehicle speed sensor shorted out and fried the harness for the speed sensor and the wires going to it and also started to melt my fuse block next to the obdI connection. the fuse in the fuse block that should have blown because of the short. it melts and just arced across keeping the connection alive. so right now i dont have a speed sensor and i gutted the wiring out and put new wire in. but im having a hard time finding a speed sensor. and the harness that goes to it. im gonna have to make my own. cuz its melted to the sensor and wont come off lol.

with in the next hour or so i'm gonna put everything to stage 1 and hook it up and try again to get a couple logs.

i'm not completely stock now tho. but i'm less modded they everyone else that is using an emanage. lol.

mods done are listed below

`255lph fuel pump
`hotwire
`dn rear pre-cat
`3inch straight exhaust no cats at all (two 40 series flowmasters)
`fuel lab a/fpr (idle set to 40psi)
`intake cone and aftermarket y-pipe
`blitz dsbc
`egr delete and vac hose reduction

with the new engine and everything i've only put on about 300 miles so far. so i'm probably only gonna boost up to where i think its ok. since its not broken in all the way yet. also new clutch (stage 2 south bend)

i'll post back around 6pm eastern time

alright well since i couldnt find anyone to ride with me around the house. i could only do the emanage data logs i got 11 data log runs going down route 40 in traffic. kinda tricky but i got some logs for you guys.
i dont have winzip. i have winrar so i couldnt upload them but
to download them go to my server heres the link

http://68.55.253.10:16000/server/homepage(2).html



ALSO IF YOU LOOK AT MY SERVER AND LIKE THE IDEA OF THAT. PLZ PM ME YOUR MAPS AND DETAILS OF MODS AND I'LL DEF ADD THEM TO MY SERVER. DOING IT THIS WAY WILL KEEP EVERYTHING TOGETHER INSTEAD OF HAVING TO SEARCH THREW LOTS OF PAGES TO FIND OUT WHAT KIND OF MODS AND VERSION EMANAGE YOUR USING WHEN YOU MADE THE MAP.

From your datalogs I observed the AFR likes to stick to 14.7 AFR below 0psi and then suddenly switches to 12.9 AFR and gradually goes richer as the RPMs increases. After 3+ psi it goes into 11.8 AFR which is a bit richer than I thought for such low boost.

So with your rewire, does this mean emanage ultimate is now functioning correctly for you? And if so, I suspect the faulty speedometer may had something to do with it, as boomslang has the speedometer wired in.

My final question, do you still utilize the high/low voltage fuel pump relay?

[sleeper3000]

the data log you downloaded from me (cold start, getting it warmed up) it was a cold start which means it had more fuel to start off with until it was warmed up. when its warmed up and just driving around it likes to stay near 15.6 - 16.00 a/f ratio.

let me know what kind of logs you guys want. i can turn down the boost or up and also run at certain rpms. but like i said. new engine and stuff. i'll only do what i feel safe with doing so far.

as for the high/low fuel pump relay. i have my fuel pump hotwired all i did was hook up the wire and relay that came with the kit from 3sx. so if that bypassed the high low relay then no i dont use the high low relay.

and yes i have it just at stage 1. just the 6 wires. and it works just fine. i'm thinking the speed sensor was my problem. i seen it had an in and out for the speed sensor and was like shit. thats probably been my problem all along. but all well.

and also yes i know it runs a lil rich. i have the egr delete done to the car. and i might have to turn down my fuel pressure. it might lean it out a lil more. it runs to rich for me.

i got the a/f meter to read as close as i could get to the real a/f ratio that showed on the gauge. ended up being 10.00 - 19.50 in the settings.

[sleeper3000]

latest logs ( one going to work and one on the way home.)

on the way to work same settings as before but rescaled the graphs to my car and fine tuned the a/f meter so it reads dead on now.



on the way back how ever on my blitz boost controller i jumped the volume up by 5% and found out by the time i was home that it only went up about 1psi

but good news is i was recording with the emanage and the hand held halo.
so even more data for you guys. also boost was around 9psi from what the greddy pressure sensor said. but on my blitz boost controller it said .76 bar. but then again thats only showing peak. not constant. so maybe the greddy sensor is right. but .76 bar is 11.4 psi to where the highest it shows in the logs with the greddy is i think 9.6 psi

dunno but at least it runs with the emanage now.

newest logs are already added to my server

Well....I have some good news. I finally got around to installing the 680cc injectors and going stage III. I pulled the stock O2s, threw Gray Haze's new map on the EMU, put my injectors/lag times in the global sizing, and it fired right up and ran steady at ~14.7 at idle after warm up.

I saw a couple of issues:
From what I have read, the car is supposed to run a little richer when the car is cold, but I saw the opposite. It was running around 16-18 AFR. So should I add some fuel in to make it richer? I never had a WBO2 on my car when it was stock, so I am not sure if that is normal. Either way, after it warmed up, the car went to ~14.7.

I then decided to take the car out for a little spin around the block. I got on it a couple of times and realized that my boost controller was set to 16PSI. Oops. So I dropped it down to WG pressure. Either way, the car bucked like crazy like it was hitting fuel cut. My first thought was that I hit the 100 IDC issue, but the logs said other wise. I also noticed was when going WOT, the car ran really lean (probably causing the bucking). I noticed this and let off as soon as I saw it go lean. I tried this a few times thinking it had to make the adjustments, and the same thing occurred. I do have the WBO2 hooked up to the EMU and used just what Gray Haze had in the target map. Going back through the logs, it was referencing it. So why would it not adjust?

I also noticed that my car is in obvious need of the Accel Map. Just trying to accelerate from a stop, I notice it goes lean and starts to knock. So I need to figure that out before I really take the car out past the block. What's the process in tuning the Accel map? Just throw in some #'s and test it? Or is there a more efficient way to do it?

Thanks again and you guys are awesome!

stealthII: After looking at your logs I'm surprised your engine is still alive. You've left the "I/J map" pretty much empty or 0.0% correction at high boost levels, this becomes especially dangerous since your map says to stop adding fuel (boost cut limiter) and the "I/J map" is responsible for the additional fuel, which has none.

If you continue to use this tuning strategy, run waste gate boost pressure and verify everything is good and increment boost slowly.

Don't expect AF Target map to write you a map especially at WOT. There's so little time for the AF Target map to make adjustments, too risky.

That is very good to know. I knew the engine was going lean, and that's why I did not consistently run it. I was going to take it out on intestate and do a 3rd gear pull being under the assumption that the A/F map would take care of it. So I am glad I didn't and you brought this up. The funny part was during these runs, I didn't receive any knock on my PocketLogger but noticed some knock on the EMU. I guess my engine has a will to live after all.

Just a question on your 550CC map, why is it that you do not have any corrections in the I/J Map as well? Do you have your car dialed in pretty well just using the Airflow Output map?

Either way, I'm going to get the car professional tuned at Titan Motorsports and stop trying to tune it myself. I think I need to get away from the Gray Haze base map and just get a new Output map created. I don't like the fact of using the Global Injector sizing and I think the last thing I want to do is rebuild another motor right now.

Thanks again.

I've posted many maps so I'm not sure which one you're referring to. A couple months ago I switched over to stage 3, but I can't boost past 8psi, either my boost controller is broken, or I have a major boost leak -- haven't had the time to investigate which it is yet. But at 8psi and lower, there wouldn't be anything in the I/J map to add fuel.
