I an getting an AEM EMS... Is there a base map the TT have to start with or does the unit come with one? I have basic mods (intake, DP, Exhaust)

 

the unit comes with base maps but they are only to get the car started. I am sure that TurboTrix has several of their own to get closer on most of the calibrations. The stock basemaps are ok but they aren't somthing you can trust without have the proper tools. Also you can't just plug it in and go drive, well you can but you must sync the ignition timming first before driving the car so keep that in mind if you are installing it yourself.

Congrats on the new purchase.

 

Thanks and hopfully someone could hook me up with better map that the one it comes with

 

i have a great start up map and you can run it also just not alot of boost until you finish tunning it

 

Yes the unit comes with a base map, and will start the car. The map it comes with in the box will work fine with your mass air box. You do not however need to adjust or sync anything with your timing on that particular car.

Thats funny because if you put a timing light on my car the timing was off about 1 degree or more, it basically wansn't right on and the comp delay had to be set correctly so the timing wouldn't walk up about 2+ degrees at 4000 rpm and above. I think you would rather be safe than sorry. Mine had to be set. I would be alittle worried if it wasn't atleast checked on every car that the EMS is installed on. The base maps aren't set properly enough and every car is just a little bit different.

 

I'll foward your message on to Jason @ aem for a response. There is no cam adjustment on a cam sensor for that car. Again there is no need to adjust your timing. I cant believe you can notice a 1 degree diff with a timing light from that angle on the evo. You have to read that light at about a 30 degree angle just to see TDC. You might of had timing adjustments for idle control and you could of been adjusting your base timing which would be very dangerous. The timing does not creep and is dead on from aem. I dissagree , base maps are set very well from aem

Thanks for the input.. When is TT comming to FL again?

 

I am glad that you disagree but first it isn't that hard to read the mark on the crank with a timing light. Dang I would hope even you could say that being a very well known tuner, maybe hard for you for me it takes about 60 sec to get it ready. As for Jason thats cool becuase several engineers state that anytime you hook one up you have to sync the timing, if you upgrade the software version you also have to sync the timing. Not just one person will say this from AEM but several. If you would like to take a look just jump on the aem fourms and have a look it is posted there more than 10 time just in the first few pages. As for adjusting the base timing the base should be at tdc basically but changing the entire map to 10 degrees then putting the timing light on the car. Set the light at 10 degress so the crank mark reads tdc and if it does you have to sync the EMS to match up this way the timing you put in is what you are running. You do this at idle then after idle is set you rev the car to 5000 rpms and set the comp delay so the timing does walk up or jump at any given rpm and it should still measure at TDC both being at 10 degrees. I can do this in about 10 min and I have done it many times to make sure my settings are correct and they are. As for yours and the cars you tune each car should be checked if you are doing it the right way. Open up the instructions and LOOK! It is right there even.

The base maps get you started but that is it. For example check the Evo MAF.cal and the Evo MAP.cal from the factor. MMM the MAF.cal looks exactly the same but the load points are changed and read lower on the MAP.cal than the MAF.cal. They didn't even take time to make all of the scaling adjustments. Also another example Look at the 1.03 cal files and the 1.11 cal files for the evo. They are nothing like the 1.03. They besically look like older DSM files moved over they are nothing alike. You would think to be safe they would be the same files with the same settings basially.

Sorry to spoil your top notch tuning session but you can't take anything for granted when tuning several or even one car with the same product.

There is a CAS adjustment under the sensor list and this is what is adjusted when you sync up the timing. Using the timing sync menu.

 

Mark, when I go ahead and step up to an AEM would you guys be able to upload a map for my current mods(intake, cams and exhaust)? Would you suggest I get the AEM with UEGO or will the box w/out the UEGO do just fine? Ah f*&k it, you and Junior down to make another trip to Pcola for tuning my AEM? I know that at least 3 of us down here are planning on it soon.

 

^^You better watch your mouth Wrick before I wash it out with parts cleaner!!^^I dont know if my car take another one of Juniors test drives!!LOL

 

You do NOT adjust the timing on an EVO....PERIOD! If any engineer at AEM told you anything, it was to CHECK it to make sure there are no problems, but you DO NOT adjust it. The EVO is wasted spark, most timing lights can't cope with dialing back wasted spark ignitions. The timing is set and verified in the base calibrations by our engineers here at AEM. Since the timing is NOT adjustable on the EVO there is no reason to attempt to make changes....you will just be making it wrong.


Jason.

 

If it isn't adjustable why does the setup ask you to verify it when you install the EMS. Next on your support forms everyone even several engineers talk about making sure it is synced. Even the instructions say that it has to be checked. Yes some timing guns have problems with the wasted spark setup but not all do. Wait let me quote your instruction manual so sit down for just a sec.

Set g (Verify ignition timing. Select the Configure drop down menu, the ECU Setup | Set ignition . Use a timing light and compaire the physical engine timing to the parameter Ignition Timing displayed. Use the advance/retard buttons to make the timing match.

That is right from the manual, the EVO specific manual. So are you saying that the manual is wrong? My car was close but I was able to get closer by following instructions and the people on the AEM FORUMS. Once I got the timing as close as I could pretty much dead on I then reved the engine with the light attached and you could see the timing climb as the rpms did. Adjusting the comp delay signal was able to draw that out so it is dead on accurate throught the entire rpm range. I am just trying to lend a helping hand here, I would rather be safe than sorry and put my ego in my pocket than have anything setup incorrectly on someones car. So please only take it for what its worth to you and that proabaly isn't very much. Regardless I have posted an tif image below from the manual so you can check it out. There is no need to arge though so this really shouldn't go on.

The manual has left out some key information, and is a generic manual, not EVO specific. The same manual gets tweaked for each application. It should state that if you have adjustable cam gears, and have adjusted them to perform this procedure. You do not need to adjust the timing on the EVO with stock cam gears or unadjusted adjustable gears. Setting timing has too many variables, including perspective eye sight. Leave it as it were in the base map.

Jason.

 

That is the evo manual, if the manuals are specific that is sad and lazy but o well that is a misshap on AEM's part I guess. I do have adjustable cam gears and I do realize that this was probably part of my issue to start out with but the TDC mark isn't the same on every car from cam to crank even on stock stuff (belt wear, tipical advance or retard from factory as several have seen maybe 1 degree + or -), I would agree probably not as much as a varence but. To many factors just like you said so in several cases it will probably be close enough but still I would rather be safe than sorry and check it.

Below is the rest of the pdf instruction file so you can see that it is for an evo. You will need to change the extension to .zip from .tif to unzip the file.

That is all
