hey guys, i'm in need of your expertise. i'll be driving 6 hours to pick up a car that i'm buying tomorrow from E Swift on here. the problem is that his EMS has no base map nor does it have any other programs on it. I think i'll be able to at least load a base map on it tomorrow...the problem is, he also has a Wideband installed. how do i set the EMS to self tune so i don't waste so much gas driving back home! i know that i set the a/f to about 12 or 12.5:1, for decent gas mileage...but i don't know the exact steps. if anyone knows how to do this PLEASE post the steps on what to do. oh yeah, do i also have to set the WB as the primary O2 sensor??

 

(Assuming this is a 1.0 or 1.03)....

You'll need to load a base map w/ the new software, and run through all the wizards. The auto-tune thing doesnt magically make everything better, it only
slightly adjusts values within a specified range, and determined percentage.
Its not like its going to bring your a/f to a perfect 12.5:1 strip if you are running
at 9:1. You may want to see how well you can get the thing to idle first, ... much
less drive around the parking lot.

Read up on the tuning functions and the setup wizards in the included AEM PDF's.

also depending on what you have the weighting set at it is real harsd to get the ecu to see all the load cells.
auto tune is nice to give you a base map but you will still have to manually edit the cells to get the car right.

 

self tuning doesnt work that great from what Ive seen. you would be better to ask this on the AEM forum.

i've already asked but that forum moves SOOO SLOWWW. and i need to figure this out by tomorrow since i'll be trying to get the car up and running by noon tomorrow. i've only got about 4-5 hours to do this as well so i will need all the help possible.

 

auto mapping is basicly a bandaid feature to sell more EMS's, same as it is with hondata. an experienced tuner can have the fuel dialed in way faster than automapping can. give me 15-30 mins on the road or about 3-5 dyno pulls and the fuel is done.... automapping cant do that. i used it once and never again. it just takes too long.

my advise to you is to find a good tuner to get it started and running good. if you are willing to learn you can take over from there.

 

If you can get a base map and the wideband is calibrated correctly, then you should be able to adjust the fuel table appropriately. But there are so many other issues that need to be addressed. Just because you have a smooth fuel table or A/F ratio, doesnt mean the car is gonna drive with no problems. You have to worry about Idle, accel fueling, ignition maps, etc. What you are asking isnt exactly the easiest thing to do, let alone try to explain here. If it were that easy, there would be no such thing as certified AEM tuners. Hopefully you will have access to the PDF docs that come with system, they can walk you through atleast calibrating sensors and getting the car to idle. If you can actually get a base map for the car, and get the laptop connected to the ECU with proper firmware and AEM version software, the first thing you are gonna want to do is calibrate the wideband. Then you can start messing around with A/F in the fuel tables.

 

Do you just want to get this thing to run so you can get it home? Jdogg why dont you whip up a suitable base map to run with his sensors. Dont worry about trying to "autotune" just yet. PM me or Jdogg and we should be able to give you the steps u need to get it running, hopefully.

YES!! that is all i really need...you're a LIFE SAVER!! all i really need is a basemap that will get me home. i have to try to load the map into the EMS and see if it starts and if it does...i just want to take it home. the other maps that i have i'm not sure whether i'd be running lean or too rich that was the reason behind the auto mapping. i didn't want the car to die on the way home cause that would be a 8itch. i'll PM you to see if you can get me a basemap for the setup!!


thanks again HT.

 

Man the more I think about this, the more it screams "Bad Idea". You should just try to drive the vehicle home on a stock ECU and have this thing re-tuned later by people who know what they are doing. If you are buying the vehicle, and its so heavily modified from stock that it cant be salvaged without an AEM EMS, .... then do the right thing and have the new investment transported by flat-bed to where you live.

This way there's no risk to anyone, and you dont screw up your new purchase by trying to drive it on public roads. Take the time to have the pro's calibrate and re-tune everything on a dyno and confirm wideband readings w/ the dyno wideband at your liesure later on.

i know i should...but money is limited now...and taking a flatbed is more $$$. if worse comes to worse...then i'm just gonna have to go to u-haul or something a rent one. either that or drive back, get a truck, rent a tow dolley and go from there.

 

thanks Muckman and 9psiTurboSi for helping a fellow H-T member out. got the maps and instructions on how to get this badboy going tomorrow. i'll let you all know what happens tomorrow when i actually set foot in the car.

 

Good luck!

As for Automapping... I tuned a basemap using it a couple weeks ago. I guess it kinda works but not really well. Its hard to sample all the nesseccary cells in the map. Also once its done and you start interpolating values by hand your damn 3d fuel map looks like the rocky mountians! However, if you can't get to a dyno right away and there is nobody to tune your car for you automapping can get you pretty close for cruise driving. Set your target values for closed loop and turn it on after your done. Should be good enough to get you by.

Unhook your charge piping untill you can get to the dyno and have it tuned!!!!!!!!!!!!!!!!!!

Again, you have ems, you have really slick datalogging....Play with it!!!!

 

So what ever happened to this senario? I'm kinda curious if the car got running / driving / home.

 

yeah I wanted to know also. I was not going to say anything when he first posted but I think he was in for a treat going there and thinking he could just load a base map and the car would be able to drive home. I could be wrong but knowing aem I am sure it was a fun day.

 

I hope he knew to use an old laptop, or use the serial adaptoer to use his newer laptop, bceause he wasn't even going to hook it up if he didn't. It's just something that goes overlloked alot of the time

 

yeah guys i got the car home...lol. but i had to do it with a stock civic ex ecu and stock injectors. i couldn't update the firmware on the EMS for some reason. i followed Muckman's instructions and it would let me do the first couple of things on the check list and then the last 2 it would just shut off for no reason. i tried this with my laptop(usb to 9 pin) and Eric's laptop(9 pin to 9pin), and it did the same thing with both of our laptops. anyway, i couldn't get the car started even with the stock ecu/injectors so i had to trouble shoot...and it turns out that the people who wired in his alarm did a shitty job and the tuner we took it to a few weeks ago fucked up plug 'A' on the ecu!

well i really got to get going to best buy to get a new alarm installed so i'll tell you guys what i did later...if you guys even care...lol.
