dangerous brain Posted November 6, 2007 Share Posted November 6, 2007 I am unable today to gain access to my aem as I haven't got the serial to usb adaptor drivers on my pc but in the morning i will remedy that. In the mean time though I would like to know if there are any generic t67 0.68 a/r inlet 0.96 a/r exhaust turbo 650 side feed injector AEM maps around. I am having no joy starting my car since the battery went flat. Now when I got the car from michel lane his car did exactly the same thing and he diagnosed it as the aem dumping his map when his battery was flat. I can't locate the download i did of my map to my pc and dan turner is not exactly an easy man to get hold of from holland if you missplace his phone number to replace the map. Also how do I go about loading a map into the aem? Cheers guys. Quote Link to comment Share on other sites More sharing options...
Robert Posted November 6, 2007 Share Posted November 6, 2007 You can have mine mate, should be ok off boost for a while? Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted November 6, 2007 Author Share Posted November 6, 2007 Ah ok can you email it to my msn email address along with perhaps a retard proof way of loading it on the aem please?? Quote Link to comment Share on other sites More sharing options...
Robert Posted November 6, 2007 Share Posted November 6, 2007 No worries mate i'll do it in 20mins or so Quote Link to comment Share on other sites More sharing options...
TLicense Posted November 6, 2007 Share Posted November 6, 2007 I don't think the AEM will dump the map to be honest mate. I had mine disconnected for over a year and managed to pull the map off it. Still, putting a new cal onto it couldn't be easier. Connect up your laptop to the ecu. It's suggested not to use USB adaptors, and I've never used one, but I'm sure it'll be fine. Boot up AEMPro. When the message appears asking if you want to connect or work off-line, select work off-line. Then select the ECU menu at the top click on connection port and select the coms port that you are going to connect using and click OK. Personally I would then try to pull the map off of the ECU. To do this turn the ignition on (don't try to start the car, but make sure your immobiliser is off) and click on ECU connect. You can do this by clicking on the plug icon on the toolbar, by clicking on the ECU menu then selecting connect or by hitting shift+F7. A window should appear saying ECU status and another window with "connecting" in the title bar. It should connect in a matter of seconds. If after 10 seconds, it's not connected then somethings wrong, and you will need to check your com port settings. Also check the physical connection of the serial lead to the ECU. The map should then start to download. You should see a red bar at the bottom of the screen indicating the download status. When this get's to 100%, the map you've just downloaded should then load up. If you save this in a folder that you're not going to delete as "workmap.v1.19". By saving it as this name it will stop you from having to download it again the next time you connect. However if you modify the workmap when the ecu is not connected, you'll have to download it again. IF for some strange reason, the ECU is blank, then you'll need to upload a map. To do this, fire up the AEM software, turn the ignition on (don't try to start the car) and then select the icon with a file pointing to the words ECU on the toolbar, or select ECU from the top menu and select "send new calibration" or hit shift+F8. The software will try to connect to the ECU in a similar way to above. Again it should take just a couple of seconds. Then a window will appear asking you to select the file that you want to upload to the ecu. Click send or OK (can't remember which) and it should then upload it to the ECU. Uploading and downloading can take a minute or two, but there's a menu bar that appears that let's you know how it's getting on. If it pauses for more than a couple of minutes then it's not worked, and again you need to check the coms. I know that looks like a lot, but it takes about 20 times longer to type/read than to do. I've had one case where I couldn't download the map from the ECU, but I could still drive the car and everything worked. Luckily I'd saved the map when I'd changed it, so all I did was upload it again and since then it worked fine. If you have any problems mate, give me a shout and I'll see if I can help you out.

dangerous brain Posted November 7, 2007 Author Share Posted November 7, 2007 Thankyou very much that was exactly what i need Tony. I've downloaded the map before a couple of times so I know the procedure for that. My laptop had a bit of an oopsy and I lost those downloads unfortunately. I was going to attempt to download the map first to see if it has one and if its in one piece. Its the upload that I've never done before and I am a bit paranoid about loading stuff onto an ECU in case I nadge the thing up completely. If its that easy then i could get the car started and off boost take it up to arnout here in Holland. If not I will trailer it there.

dangerous brain Posted November 7, 2007 Author Share Posted November 7, 2007 Right I have changed the plugs this morning. The car starts and runs now and drives ok. My pc logs onto the aem but thats about as much as it will do. I am getting nothing more from it. When I save something its called cal name WORKMAP. Open it and theres nothing there. Am I right in assuming I should have that (technical speak here lol) black background with green or yellow lines all over it and red graph lines on it? There's none of that. When I switch on pc logging and save it the file says there is no data in it. The car at idle is running sooooo rich its unbelievable. The plugs I removed are blacker than midnight which means I have an overfueling problem somewhere (this is after I had the aem fitted and mapped for overfuelling issues I had with the fcon that came fitted). So questions here. Is the map called WORKMAP some sort of failsafe thing? Am I having connection issues with my AEM and PC? The laptop I used before connected no problems and I saw all the same stuff on that one as I saw on Dans laptop when he was tuning. I am using a different laptop now.

Robert Posted November 7, 2007 Share Posted November 7, 2007 My map is called WORKMAP, when you open the software up, have you noticed the little download window with a red bar? that has to completely download your map before you can save it. i just the go to 'Save As" and it saves my map to where i want.

TLicense Posted November 7, 2007 Share Posted November 7, 2007 Workmap is the default name of the map. All the maps in the ECU are called workmap, even if they're called something else on your laptop. That's why if you change the workmap when you've disconnected, when you connect, it checks to see if the workmap in the ecu is any different to the workmap on the laptop default directory (it does this by comparing checksums) and if it's different it will download the workmap from the ECU. If they're the same it just connects. So take us 1 step at a time as to what you've done to get the car running. Did you manage to download a map from the ECU or did you upload Roberts map? Have you got an AFR gauge on the car or hooked up to the AEM? If so what's it reading at idle? Robert, the map you sent to Brian, what injectors do you have, and what's the base pressure? Also what MAP sensor are you using? Brian, you need to set your car to suit the map that Robert has sent you, or adjust the map that he sent you to suit your car (which is a lot easier obviously) If you see what I mean. You need to adjust the injectors to suit, and also tell it that the base pressure has changed from whatever Roberts pressure is to whatever yours is.

Robert Posted November 7, 2007 Share Posted November 7, 2007 i've got 650cc injectors the same as Brian, running stock fuel pressure i think, although i will double check. Im using the AEM 3.5bar sensor. Quote Link to comment Share on other sites More sharing options...
TLicense Posted November 7, 2007 Share Posted November 7, 2007 Cool. What FPR have you got? If it's stock then it'll be running at the stock pressure. Obviously if it's aftermarket, then it could be anything. I'll check to see what the stock pressure is. I think it's something like 3.5bar, but will double check.

Robert Posted November 7, 2007 Share Posted November 7, 2007 I've got the aeromotive FPR with a gauge attached, i'll go down now and have a quick look Quote Link to comment Share on other sites More sharing options...

Robert Posted November 7, 2007 Share Posted November 7, 2007 The fuel pressure is 32psi at idle Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted November 7, 2007 Share Posted November 7, 2007 Roberts Map has the O2 Feedback switched on for the WHOLE fuel table which is using the wideband to work out the fueling. This is fine up to say 0psi of boost and 4500rpm as is like closed loop o2 correction as on the standard ecu but i exspect where dangerous brain does not have an AFR sensor wired in to the AEM, it will be just using the map and as the same as all the other maps that have been done this way by a special AEM mapper it will be PIG RICH like 9:1 Quote Link to comment Share on other sites More sharing options...
Robert Posted November 7, 2007 Share Posted November 7, 2007 If Dan mapped Brain's it will be the same Ryan Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted November 7, 2007 Author Share Posted November 7, 2007 OK so more information then. First up my car has an FPR of some sort, the spec sheet says HKS but who knows. I have no pressure gauge on the fuel manifold so have no idea what pressure its running. My MAP sensor is something that michel lane gave me, I have no idea what it is apart from its maybe a 5 bar MAP sensor. I have indeed got 650 cc injectors. OK so when I go through the whole log on process to the AEM I get all the red line at the bottom saying downloading. Then I get a half screen box telling me I am connected to the ECU. Now at this point I used to get all the graphs. Now I get zilch just that half screen which is minimiseable within the aem software box.

suprafan72 Posted November 7, 2007 Share Posted November 7, 2007 I believe "Our very own special AEM Mapper" Did make Brains car.. so i guess it will be another Classic Timing curve like the Canadian Rocky's and the good old classic with "O2 Corrective Feedback switched on" We should have a "Mapper of the year" contest.... Anyway enough of my rant.... When your ecu reckons its connected have you tried to look at other views such as the igntition and fuel tables to see if there is any stored values?

dangerous brain Posted November 7, 2007 Author Share Posted November 7, 2007 I don't see anywhere to change the view on it. I don't want to poke around too much as I don't know what I am doing. And yes mr Turner mapped my car. I don't know if the aem wideband is plugged into the aem ECU or not. Now the laptop has recharged and I am eating a meal I can finish up and go outside and take screen shots if that helps Quote Link to comment Share on other sites More sharing options...
Robert Posted November 7, 2007 Share Posted November 7, 2007 Yeah take a few screen shots mate, does seem abit weird. Quote Link to comment Share on other sites More sharing options...

Now the laptop has recharged and I am eating a meal I can finish up and go outside and take screen shots if that helps I guess your AEM will be wired into your ECU at the moment.. As Mr Turner's Mapping methods use's the values on the AEM Wideband for O2 Corrective feedback as it uses the Wideband to correct (within 5%) the WOT Values it see's from the Gauge. Hence its dangerous to use this method especially if the gauge or sensor fails it looks at this and correct's the figure within this 5 per cent tolerance...Kaboom springs to mind Quote Link to comment Share on other sites More sharing options...

dangerous brain Posted November 7, 2007 Author Share Posted November 7, 2007 OK sitting at idle I think its fouled the damn plugs again. I found my way into one of the graphical display pages. I clicked on setup and some parameters and break point tables came up. I clicked on home and a rev counter and other stuff came up. Apologies for the crap explanation but for some reason this laptop won't do a prtsc which I usually use for screen capture. An interesting note though is that the readout of afr on the home page was 14.7 ish when the afr gauge in the car is saying 11 surely thats not right? I'm gonna have to pull the plugs and clean them again now I think. Or how do you pull the fuse on the fuel pump to turn the car over without fuel?

Ryan.G Posted November 7, 2007 Share Posted November 7, 2007 how do you pull the fuse on the fuel pump to turn the car over without fuel? You can just turn it off in the aem software but the easiest thing for you to do is in the boot on the left hand side, under the spare wheel there is a connector which goes to the fuel pump. Just disconnect it Quote Link to comment Share on other sites More sharing options...
