Hey guys Sometimes Internal Logging works, usually it does not tho. This is getting very frustrating and I could really use some help.

I'm trying to Internal Log by meeting all Conditions. Right now the Only box I have 'checked' is "Log Always". Conditions are as follows:
Load at least= -12psi
Throttle at least= 10%
RPM at least= 1500rpm
VSS at least= 0mph

I have tried this in many different combinations. "Log Input Switch" is set to "Switch is always OFF".

 

Try using these settings.
If you use: RPM at least= 8000rpm Then it will only record past 8000rpm.

 

The way you have it set up now is it will only log 2min and 37sec worth of data once that is full it will no longer data log. You can slow down the rate to get more log time or you can turn on loop logging and that will keep your most recent 2 min and 37sec. Log Always will ignore your Conditions below.

 

True, but the faster rate sample is much better for knock tuning when you use a knock sensor.

 

I don't want to Loop Log. So I want nothing checked and Switch is always OFF selected then ??

 

Yes you could but when the internal logging gets full it will stop recording new data.

 

So your saying if I go past that 2:38 the slightest it will record Nothing?? I just want to meet the conditions make a pull and drive some were safe to stop and read the log.
Once I meet all conditions and do a pull, wouldn't it just record everything from the time the conditions are met for 2min 38sec. Or does it actually record NOTHING if you go beyond that?
I called tech support at aem today and was told
I need "Log always" checked and "Switch is always ON". I'm pretty sure I tried this changing to "Switch is always ON" and I don't think that worked either.

 

I already gave settings that works. You only have to change the conditions to meet when you want the recording to start. Once the recording starts it keep recording a few seconds past the recording conditions.

 

So if I loop log, will the conditions have to be met again to overwrite? Or will it just keep overwriting until I key off? Because I just want the WOT pull, not the drive back from doing a WOT run(most current would be drive home). So say I set TPS to atleast 60 hit that make my pull, then keep it under 60% on the drive tithe spot to review the log? Dyno
Is expensive and I'm out of town. Thanks for the help

 

Do you have a lap top?

 

I was about to say the same thing. Plug in a laptop open the software up to the page of channels you want to datalog and simply press F6 to start logging. Press F6 to stop and save the log.

 

Haha, of course I have a Laptop. I'm street tuning, I have the Laptop mounted FF syle! F6 starts "PC Logging" tho. I want to get some Internal Logs for Fine Tuning. I haven't been given a straight answer from aem tech support ever. Last year I gave up trying in a week and went off PC Logs. But, not this year. I need those MUCH faster rates from the Internal Logs. I just can't figure out how to get it work by using the Conditions. I haven't explored any other way of getting it to work either. But, I assume if I can't get it to work by meeting my conditions, then why would it work any other way lol? Have either one of you experienced programming an aem? Do I even need "Log always" checked like the AEM Tech told me? He also said I need the "Switch Input" set to "Switch is always ON". But, if that's the case wouldn't I also need to check the box "Log Switch".
I have tried so many different combinations but, still haven't gotten it to reliably work. Out of town right now... Some good experienced person who has setup internal logging based off meet the 4 conditions. I would love your adivce here

 

Tell us the conditions and how you want it to log and I will tell you exactly how to set the whole thing up.

 

I have told you I want to log WOT mostly. Also need to setup Injector timing down low. I know what the conditions mean and how to set those up. I need to know what to check or not check and what to do with that "Switch Input" If you setup off conditions, then tell me what to setup please! You can see the screen shot I posted.

 

Options you can unclick everything.

Log switch Input does nothing since you don't have log switch active up top.

Conditions set these to what you want them to be.

Rate set your rate

Once you have all your conditions set click log reset you can even click it a few times. Click OK.

Key cycle the car.

If you fill up your log data than it stops logging with loop logging off.

Also make sure you have Perm Power wired to the EMS. If you don't and you key cycle it will not save your logs.

That should be it.

 

This could be it. I usually key cycle. I don't know why key cycle but, that is what i'v heard to do. I will try to download the log w/out key cycle. If that don't work then i'll run perm 12v to the ecu. I usually only drive this car 1-2times a week. So the battery is unplugged 95% of the time. Is there anything besides the Internal Logging that the perm 12v benefits that anyone knows of? I plug the battery back up and the tune is always the same.

 

Perm power is pretty much just used for internal logging.

Since you sig says 94 Civic I would assume you are using a 30-1040 Series 1 EMS.

Check pin D1 this pin is for perm power. You can wire that directly to the battery.

Depending on how the log parameters are setup the key cycle would stop the log which is why people have told you to do this. However if you have conditions that are met only when you want they should close the logs automatically.

 

It's not hooked up. So I assume it needs perm power to save the Log? I will try downloading the logs w/out key cycling. I don't want to add perm power if I could avoid it. I don't want to be dealing with stuff like corrupted eproms this year...Thanks!

 

Without Perm Power you will not be able to Key Cycle and get a log. The Perm Power and the E-Prom are on two different circuits. One will not effect the other. It is safe to wire in the Perm Power directly to the battery as this is what is keeping the log in the ECU after power is switched off.

 

Finaly got around to tinkering with the Toy today. I used these Settings w/out Key Cycling and logging worked everytime.
Thanks a lot for your help Key cycling looks to have been the problem. I still don't have perm power... And yea, haha, the v1 and their eproms are finicky. I didn't want to change anything electrical. When I was working out the bugs initially I had eprom issues 2 times and it kills having to send it to Cali to get a new/used eprom put... But yea, thanks a bunch

 

Not a problem. Glad you got it figured out.
