Default Need help, lots of help.... openecu.org

Yup, planning on gettin the tactrix cable and openecu.org software

Looking for some one very familiar with how the software interface is and how it works, I don't want to blindly go into this.

Start with the Enginuity FAQ - http://www.enginuity.org/about444.html.

It has information about general reflashing as well.

Thanks thats a helpful article

I was mainly looking for the "What I should change" "What I shouldn't f'ing touch"

Only really looking to retard the timing 3-4 degrees and re-scale my injectors

Download Enginuity (or your editor of choice) and one of the factory ROM's for your particular ECU from OSECUROMS. You can dink to your heart's content without even plugging into your car, and once you become familiar enough with the software and makes changes and such, you can move on to the fun stuff.

Thanks for the help

Is there anything I should look out for when I go to retard my timing a few degrees and rescale my injectors?

how bout post in the EM forum?

also cobb put together a pretty good article/tuning guide, i found it a good read and should give you some insight as to how to start tuning the basic tables.

NP, more specifically the stock ecu reflash forum in the EM section covers all the openecu stuff, i would start there. i'm sure this will be moved there shortly.

page02wrx, you keep saying you want to retard your timing a few degrees.

Why?

Well I'm assuming the stock ECU isn't retarding it on its own. My VE is probably extremely higher than stock considering the P&P, Up pipe, TBE, and EWG....

So again, I'm assuming that my stock ignition timing is too advanced for what my car is at right now, I've been running around on 10psi till this tactrix cable comes for a few days.

Is there a reason I shouldn't retard it? I've talked to a couple people mainly two tuners who both said if I'm running more boost on a bigger turbo it would be a smart idea to retard it a few degrees. 3-5

log some runs to see if the ecu is pulling timing. if its not, then its happy. the ecu is fully capable and willing to pull timing at any point.

I would suggest getting a base map for your mods. Flash your ecu. Go for a spin and see what the logs are telling you. Once you take a look at the logs adjust them for your car.

As for timing I have add timing by the ignition correction table and I have left the base timing alone. The ignition correction looks at the IAM. When you start the car this is at 12. If the engine is happy and it doesnt detect any knock this number will move up to 16. The higer the number is the more timing the computer will add. The lower the number the more timing is being pulled. I am running stage 2. My target boost is 17.6psi. I increased the WGDC to help with some spool ( I hit full boost at ~2600rpm). I then added some timing to the ignition correction map (add a little but mostly evened it out. The stock map isnt very smooth). Finally I leaned out the top end fuel a little. Over all the car seems very happy and very strong. I hope this helps you out some. I am by no means a guru when it comes to open ecu, but this is what I have done.

Wait a second...are you running with a bigger turbo and all of your other mods you listed and without a tune? Did I read that right?

No the turbo isn't on yet, the turbo WILL be on and thats when I'm planning on tuning, I'm doin the turbo, injectors, and tactrix all at the same time with a wideband a/f.

Even with a stock turbo, how the hell are you controlling a EWG without a tune currently? I seriously hope this is not the case.

Low boost, a MBC, and looking out for PTFB maybe?

You're telling me with:

A MBC, FMIC, EWG, UP, TBE, Short ram, bigger turbo, and bigger injectors, I should just drive the car without changing anything and take logs?

I've heard the stock ecu can only pull time to a certain extent... that tolerance being about +- 2 degrees. If you have any facts about why I shouldn't retard my timing due to my extreme increase in VE, I won't... but I'm thinking better safe than sorry.

No, I don't think that's what he's saying at all. He is saying that if your concern is timing, watch what the ECU is already doing. If it's happy and not pulling any timing, then there probably isn't an immediate need to do so on your own. And I don't think he knew about all of your mods...and you just said some of those aren't on the car yet, anyways.

Very untrue. The ECU can and will pull much more than that whenever it feels the need. It is in part based on the IAM and KC values, which the ECU dynamically adjusts.

^^^ Without having access to the actual map, it'll be almost impossible to tell if the ECU is pulling timing. You wont have a reference point to what the timing should be. You could log the stock knock sensor output but that is almost as useless because of the resolution of most loggers. The best you can get with SSM is about 10 samples per second. You may catch it or you may not. If it happens in between sampling periods, you'll never know.

The stock ECU will do a lot of work to save the engine if it thinks there's trouble. It'll pull lots of timing, change to high detonation map (very rich fueling) and disable boost control. Stock timing is very conservative already so you might be OK. BTW, why do you think your VE is that much bigger given you're riding on a stock turbo? I don't see how you concluded that.

Oh, well its colder now that its winter, i've heard two urban legends, one I know is true, the other I'm unaware how much truth it holds.

1) Colder air makes you less prone to detonation (I believe this one is true)

2) You run leaner in the winter (This one I don't know if its true).

I'm afraid if I am to tune my car aggressively now that its 20 degrees out, when it starts hitting in the 60's again I could be knocking at my current settings. Then I would pull time. This means as of now my computer may not be pulling time because I wont be knocking. I'm not always going to have my laptop hooked up to know what the ecu is doing. Is there any type of sensor I can get that will tell me if I'm pulling time? Maybe something that flashes? I MAY however, have my timing too advanced for my motor, maybe I'm not knocking but I do think its too high and that is what I'm afraid of. Too much advancement can blow my motor can't it?

As far as # 2 goes, I'll have a wideband to tell but I just wanted to know if you thought it was true.

Well I was at 16.5psi, with the TBE/UP/EWG..... I turned it down just for a peace of mind without a tune, but I have a vf34 ready to be put on... I'm planning on running about 17/18psi...

I'm really a beginner in the VE and tuning world, just what I know. I have a book I read but its pretty confusing and I have to end up reading it over and over and over again, the equations and context is very hard to read...

A tuner told me if I'm going with a bigger turbo with more boost it would be wise and safer on my motor to retard the timing 3 to 5 degrees...

Hopefully this thread can get everything straightened out. I'm hoping everyone posting knows what they are talking about because I know one thing, I DONT!

Everybodys replies are much appriciated, thanks for the help.


edit: also can somebody answer this damn question for me, I'm under the impression that pulling time is the ECu retarding the timing....

my friend who worked at slowboy (Oh god) told me SLOWBOY told him that pulling time is advancing time... it didnt make much sense to me that if you knocked and the computer pulled time, that means it was advancing it?

So either I'm not getting it or slowboy is wrong.
