Ok, here's the deal. Two days ago the car was running fine all-motor on stock ecu. All we addded was aem 3.5 bar map sensor, wideband, rc750cc saturated, clips, and the aem system. We went into the computer opened my original base map, modified it over the phone with 2000civicsi. We change injector size and map sensor. The fuel pump primes and the ignition box still turns on. We have no spark or fuel in the motor? But everything in the aem basemap is switched on? We obviously missed something but we're not tuners and don't know what we missed. Any help would be a lifesaver. Thanks. Ryan.

 

bump

 

did you modify the fuel map also after doing the battery offset for injectors or did you just do the battery offset? also what fuel psi did u put in the " old to new "fuel psi settings or did you leave it the same also did you mod for wide band or did your old setup use the wide band also

 

we did not modify the fuel map after doin the offset for injectors. We didn't even find a "old to new" fuel psi setting? My old setup did not use the wideband but we didn't find anything in the aem about the wideband. Also, we put the stock ecu back in and it turns over. I don't know if that helps. We have a dyno date for Saturday so I can use all the help I can get!

 

you should be able to find the750s in the injector wizard. That just sets the battery offset for the injector, it doesn't change the fuel map. After that, go to your fuel table and then [cliack&drag] to highlight the entire fuel map table. Right click and choose the bottom option- Change Injectors/Pressure. Punch in your old injector and whatever pressure you were running. Then punch in 750 for the new one and the new fuel pressure. If you haven't changed the fuel pressure, just make sure the before and after pressures are equal, it doesn't matter the actual number. That should get you close and allow you to fire it up and maybe drive it. The injector change is the biggest thing that will affect the tune. After that, you just need to clean up the tune for the other changes you made to set up.if ya need help with the o2 set up letme know if i wheer you i would join the aem forum it will answewr all your ?

 

when you change to 3 bar map sensor in the setup it dosent rescale your fuel + spark tables. you will have to 'select all' and copy the fuel table , then select -10 through 11psi and paste. You must do the same with the spark table

 

thanks for the help guys, keep it coming

 

alright we did everything that you guys said but with still NO luck. I have the map saved on this computer so if anyone can help us out and take a look at them to tell us what's wrong that would be GREAT!

You need to change the injector size, battery offset, map sensor and change over the fuel/ignition values for the new map sensor.

 

And remember when you "Change injectors/pressure" this is only a calculation

 

I posted a modified version of your cal on your thread at the AEM site. The only other thing you may need to do is read the sticky thread about no spark and pin 22.

 

what year is your car on some 92 civics and del sols wire #a22 (I think) has to be depined on later civics and del sols the wire isnt there.

 

thanks guys. And yes, we already went to change injector/pressure and it made the changes. I'll try the new map.

 

Bump for this guy. im heading over there in a few days to help get this thing running. But I havent messed with AEM yet so all the help in the world will help.

Ryan, did you make any progress this weekend?
Call AEM tech support too like I said on Saturday. Im sure they can give you a few more options of things to look at.

Worse case scenario can we get it to the dyno on the Stock ECU and have your tuner **** with it and put the AEM in on the dyno?

 

TTT so I can get some sick footage of this car on the dyno and the streets this weekend. Without this thing firing and tuned it will kill the weekend.

 

For what its worth my suggestion would be to put the original injectors and MAP back on the car and get it running that way first. You changed too much at once to be sure of what is not working on the car. Having the MAP configured incorrectly or using large injectors can really screw things up. Keep the wideband on because the system will run open loop until you tell it otherwise so it wont matter.

The stock AEM maps usually get the car started and then you can start tuning from there. Once it runs change one thing at a time and when the car doesnt start you will know why.

 

thats what I suggested, but he doesnt want to cut the injector clips again.

I said try the AEM on stock injectors and stock map. If it fires then try the injectors first. If it still fires then put the map back in. That will atleast narrow down the probs.
He doesnt really wanna do that for no reason, but I explained to him at this point that is what needs to be done becuase tooo many things at once were changed.

Ryan, When you said it fired on the stock ecu, that wasnt with the Bigger map sensor and injectors was it?

 

Yeah it was. We had the injectors, map sensor, wideband installed when we put the stock ecu back in and IT POPED? Its gotta be something in the aem ems. If it comes down to it we'll flat bed the car to dynotec and let Steve **** with it. I can't cut the wires on the injectors anymore cuz there's no enough wire to cut it anymore. There's only so much we could **** up and I don't think we fucked up........

 

Can you PM me your setup? I mean everything.

AEM box number, all motor or turbo. etc etc.

 

so is it a bad idea to put an aem box on a freshly rebuilt engine? - as in seating the rings on shitty maps?

Not if you have some tuning experience. I've found the AEM base maps to be very good. Started first try. If you dont have much experience I would break it in with the stock ecu first.

 

im planning on having Tgreaves tune it for me, at least the first time. I would just use the stock ecu, but i dont have one

 

they dont have basemaps for my 750s tho
I just started messing with the program the other night, and i know theres like an injector size wizard, ill have to mess with it.

 

The injector wizard has the calibration for rc 750's, just click that and then change the injector and pressure, and your good to go.

 

I saw on your post on the AEM board that your car reads 14 psi when it turned on. that means your map sensor is not set up right. it should read zero. that will totaly throw off all your maps
