AEMTuner How-To series

I have created a series of How-To videos that explain the very basics of the AEMTuner software, and how to go get started on tuning your car. I know the sound is a little low, sorry about that.

https://www.youtube.com/watch?v=iGRPe93pGsA&list=PLQ0tVstZhCubcJ29HEG-lN...

Any questions you have feel free to post them in here and I will try and answer them when possible.

Thanks for the videos they

Thanks for the videos they are very informative as im staring to tune my mustang on a aem ems this year too just waiting to wire in a few additional sensors and input/outputs, I do have a question in the setup for the injectors I am currently running 80lbs there are not any options for that size injectors on the drop down list for any brand at that,which was surprising to me because 80s are pretty common in force inducted race gas applications down here. I currently have a 72lb selected is it better for the tuning point to go one size lower on the injector size selection or higher being my actual size is not an option?

There's a lot of confusion

There's a lot of confusion surrounding this topic, so I'll see if I can clear some of it up for good in this thread.

 

AEM Tuner software does not care about the size of the injector you select. What matters is the offset table. Usually when you select a given injector size, the battery offset table is preset for you and injected into the 2D table. So, when someone changes their injectors thinking it's going to fix something or rescale the map or something along those lines, that isn't how it works. It can most certainly affect your fuel map and the way the car tunes out, this is true, but it isn't the size that matters :)  If they selected an injector that has dead times (and ohms) close to what they should be running, the sizing becomes irrelevant. 

Say you were running stock injectors from an SR20DET. You selected those injectors, tuned it, and it dialed in pretty well. But later you went with ID2000s and redid the battery offset map for ID2000s, without actually telling the ECU that it was running ID2000s (via the wizard) and it won't make a bit of difference in how the fuel map tunes out in respect to the ecu thinking it's still running stock SR injectors. 

If you're unsure of what injectors you have, start by checking the ohms with a voltmeter. Just probe both pins in the injector and it will tell you whether it's a low or high impedance injector. Then, try and find the battery offset table online for those injectors or from your supplier. If you can't, find one that is closest to what you have in the wizard, and it should turn out OK. Dialing in dead times is another thread all on its own and at the end of the day if you're in the ballpark it won't make a huge difference anyway.

 

Keep in mind that this applies to both AEM Pro and AEM Tuner, AEM Infinity however is a totally different animal and it DOES care about injector size, flow, offset, etc.

Thanks for clearing that up I

Thanks for clearing that up I did select the injector in the wizard that was the same high impedance 12ohm as my injector specs called out, I was just unsure if the actual size was going to cause an issue with tuning.

Would you be able to help me

Would you be able to help me navigate the software and find the values for these settings: (http://www.supraforums.com/forum/showthread.php?644998-Caring-for-the-A340-Factory-automatic-trans-built-or-stock)

1)
ONLY lock the converter in 4th gear over 50mph under 30% throttle.
Enabling and setting up hysteresis in the AEM converter lockup controls is a must, whenever I dig up my old AEM maps I'll post them. If I havent posted them yet, then I havent had time to find them, dont ask.

2)
Timing HAS to be less than 6 degrees of timing between shifts.
 

Thanks

The volume isn't just a

The volume isn't just a little low.  I have my volume set to max on my desktop and I still have a hard time following what you are saying.  Then a youtube commercial comes on and blows up my ears.  On my laptop I can't hear you at all.  Can you please adjust the audio.  Straining so hard to hear what you are saying takes concentration away from understanding the content.

 

A tip for future videos,

When I can hear you there are breath sounds when you say words with a P or S.  If you put a piece of foam between you and the microphone it blocks those sounds and gives you a more studio quality voice track.

maybe a bit off topic- (but

maybe a bit off topic- (but first of all, great videos thanks for making them wish the audio was higher but thanks tho!)

what settings can i play with and change to make LOW rpm driveability and quick throttle blips smoother?  right now when i blip the throttle from idle, the wideband goes from 12:1 to off the gauge LEAN and it of course hesitates and then when i let off and the RPM drops, it recovers. 

drivability in low Rpm/throttle is a bit hesitant and bucks a bit too.  it might be related to the blip throttle issue? 

the car starts and idles pretty decently so that much at least i got. 

gte stock long block, 70mm single turbo, FIC 1450cc low imp injectors, 6 spd, aem v2

thanks for any help!

First, I'd suggest reading

First, I'd suggest reading the AEM Series 2 EMS setup notes -02V02 Firmware updates PDF.  There's info on what all the accerleration enrichment fuel options and tables do and how they work.  Before you attempt to tune your accel fueling you should have a good understanding of what's going on.  I find that accel fuel tuning is the least understood concept in S1/S2/EMS-4 tuning.

I just wanted to say thanks

I just wanted to say thanks for putting the time and effort in to make these videos.  I am coming from another EMS system, and these videos cleared up a lot of confusion I had as to what certian tables were actually doing.  

My car went from having a piss poor idle and light throttle drivability to having a rock solid idle and great driveability after watching your idle videos.  I can now move on to other aspects of the tune and getting things dialed up perfectly.

Hy Jon. Great videos,  thanks

Hy Jon. Great videos,  thanks.  Question though, could you possibly guide me in setting up a "stepper IAC" on my 91 MR2? I've installed  a 70mm BBk Tb with a ford IAC.  Under the options for set up of stepper motor where do I start?   Thanks  Nat

Jon, your are right, I got it bassackwards!!! It is a ford 2 wire, and yes it is wired in right based on ealier forums.  Thanks

Most Ford IAC's are two-wire

Most Ford IAC's are two-wire PWM type, not stepper.

Hi, 

Hi, 

I have a standalone AEM for a K20A2 motor. The serial number is 1070-0099 and i found another number under that one that is 10-9070. Im looking for the programming software for this AEM. Would you be able to help me with that?

Thanks,

A 1070 EMS is a Series 1

A 1070 EMS is a Series 1 which requires AEMPro software.

Same here. Thanks alot!

Still haiving issues withthe base fuel map though. AFR is all over the place when I'm holding it in each cell. Pretty hard to move on to Accel fuel and everything else for drivability if I can't get the base table setup. BTW O2FB is off.

I'm following this video

I'm following this video series and it is great so far. I cant seem to change my fuel trims table from showing tps on the left side rather than engine load. Any clues?

I would like to see this

I would like to see this series redone using the latest version 2.96.xxxxx.    Most of the tabs and layouts are very different than what is covered in the videos.

That might have to do with the fact that the videos are for the Series 2 which is a completely different product line from the Infinity.

If someone where to create a series based on the Infinity version, I would definitely be willing to pay them for the effort.   The compiled windows help is pretty good, but I think the walk through would be very valuable.
