tux Posted June 11, 2013 Author Report Share Posted June 11, 2013 I've enlisted their help. I got them a log and oscilloscope trace of the sensor. Hopefully I hear back soon. Link to comment Share on other sites More sharing options...
tux Posted June 12, 2013 Author Report Share Posted June 12, 2013 I got stat sync'ed ! AEM hasn't responded yet, but that monkey is out of the way. Still no spark, unfortunately. Link to comment Share on other sites More sharing options...
Technology Posted June 12, 2013 Report Share Posted June 12, 2013 Sweet! Have you set a plug (wired to the coil) on the valve cover/shock tower and visually verified no spark? What coil pack/setup are you using? If it's a DSM setup, it's possible the transistor is bad, but could be you need to set the outputs on the AEM differently? Once you get spark, turn off the injectors and crank it over using a timing light to get it "close" to 10 BTDC. Once that's set, turn on injectors and add fuel in the startup table until it fires. Once it starts, you can start messing with the main fuel map. turn off O2 feedback and the knock sensor for this start-up tuning. Link to comment Share on other sites More sharing options...
tux Posted June 12, 2013 Author Report Share Posted June 12, 2013 (edited) I've done the coil testing mentioned in the FAQ on AEM's forum and I get spark . Unfortunately just not while cranking. I'm using Ford 4L coil packs . I'm not really sure what's going on with it. Edited June 12, 2013 by tux Link to comment Share on other sites More sharing options...
tux Posted June 13, 2013 Author Report Share Posted June 13, 2013 (edited) Gah. They gave me a cal to try and I get spark rarely now with it. They need me get a scope trace of the magna distributor . Edited June 13, 2013 by tux Link to comment Share on other sites More sharing options...
tux Posted June 14, 2013 Author Report Share Posted June 14, 2013 (edited) Ah, got a new cal and I've got spark ! Set base timing during crank to -10 btdc and tried also 0btdc . I can't get her to kick over. :/ Edited June 14, 2013 by tux Link to comment Share on other sites More sharing options...
Technology Posted June 14, 2013 Report Share Posted June 14, 2013 Add fuel in the cranking fuel. Add and add and add. Make sure your firing order is right too. just worry about cranking fuel until it kicks off, then worry about the main fuel map. What size injectors and what fuel?

tux Posted June 14, 2013 Author Report Share Posted June 14, 2013 For now, I've got regular 87 (about 2 gals) and I'm using Neon SRT-4 Mopar Stage 2 injectors (682cc) Firing order is set for Coil / Cyl 1 - 0Coil / Cyl 2 - 3Coil / Cyl 3 - 1Coil / Cyl 4 - 2 I'll just set it to dump fuel like a mad man.

Technology Posted June 15, 2013 Report Share Posted June 15, 2013 (edited) I didn't get the firing order at first, but now I do and it's right. You may also need to use a little throttle input to get it right at first, and if you suspect it's flooding, floor the gas, that will bring starting fuel to zero to clear it out.

tux Posted June 16, 2013 Author Report Share Posted June 16, 2013 (edited) thanks for the tips ! looks like i have progress. I got some cool flames from the exhaust and sometimes the throttlebody. After monkeying around with the timing in the cal I've almost got it to kick over. Darn this battery charger and it's mere 75amp start setting I had to set initial crank pulse to 50 across the board for this .

tux Posted June 17, 2013 Author Report Share Posted June 17, 2013 well... i got nowhere all day. i feel like throwing the car at my neighbor . only because both of them make me mad Link to comment Share on other sites More sharing options...

tux Posted June 19, 2013 Author Report Share Posted June 19, 2013 I think the pull-up circuit for crank on the ems-4 went bad. Link to comment Share on other sites More sharing options...
tux Posted June 21, 2013 Author Report Share Posted June 21, 2013 scope tests prove it. EMS sent to AEM for repair. Link to comment Share on other sites More sharing options...
tux Posted July 12, 2013 Author Report Share Posted July 12, 2013 Got it back ! And after monkeying around for quite some time and checking/rechecking timing, I've got a near start ! http://www.youtube.com/watch?v=9HWdeXc6U1o But that's about as far as I got >.< Anyone have any suggestions ?

CaliConquestAlex Posted July 12, 2013 Report Share Posted July 12, 2013 Sounds like your battery is pretty low. Most ECU's won't work properly with less than 10 volts. Also, it was mentioned above, but add more fuel and then pedal it to try to get it started.Floor it if you think you've flooded it and it will stop additional fuel from being added. Also, make sure you have your TPS min and max values setup so the ECU knows that the throttle is fully closed or fully open. Link to comment Share on other sites More sharing options...
tux Posted July 12, 2013 Author Report Share Posted July 12, 2013 That's all been done. Battery is run parallel to a deep cycle battery and a charger . I guess it could possibly not be enough, but voltage is 12.3v . I'll keep doing fuel, so far I've added quite a lot to get it to this point .

CaliConquestAlex Posted July 12, 2013 Report Share Posted July 12, 2013 so you've verified that you're getting a good spark on all 4 plugs at this point? What worked for me was to increase the fuel while cranking to the point where I could smell the fuel because it was getting flooded and then I floored the throttle to enable flood/clear mode and kept cranking and it fired up. Once you can get it to fire up, then you will tune the fuel table to get it to stay running without having to pedal it. Link to comment Share on other sites More sharing options...
CaliConquestAlex Posted July 12, 2013 Report Share Posted July 12, 2013 Also, you should try to verify your base timing if you haven't already. Charge up the battery so you can get a fast enough cranking rpm to trigger a timing light and have a friend crank it over while you verify that you are 10 degree btdc.

tux Posted July 15, 2013 Author Report Share Posted July 15, 2013 Got it to the point of it kicks over and runs for a second or two then falls on it's face. I've got the fuel map increased like nobody's business at this point. Getting closer. Link to comment Share on other sites More sharing options...
CaliConquestAlex Posted July 15, 2013 Report Share Posted July 15, 2013 What size injectors and what is your base fuel pressure? You might not be getting enough fuel. Link to comment Share on other sites More sharing options...

Technology Posted July 15, 2013 Report Share Posted July 15, 2013 If it starts and dies, you need to adjust the main fuel map. You may need to increase it a lot if the injectors are small. But you are at the point where only more fuel will make it run. Congratulations! Link to comment Share on other sites More sharing options...
tux Posted July 17, 2013 Author Report Share Posted July 17, 2013 I just ordered a 300/60/4/2 amp battery charger. I'm sick of being able to play with it for 10 minutes every 4 or 5 hours and getting no where >.< Link to comment Share on other sites More sharing options...
tux Posted July 24, 2013 Author Report Share Posted July 24, 2013 I'm not getting very far. Found that backing off a little on the fpr spring gave me more steady fuel pressure (43psi as opposed to 58) and I'm able to drop the fuel PW down to 1.9ms from 6ms (where it was before to get it to run a few seconds). Sometimes it starts, sometimes I have to crank a while... When I get it running still 5-10 seconds max for an idle. If I apply any throttle, she dies instantly. Beat >.< Link to comment Share on other sites More sharing options...
