AEM help

Ok it took me all day but i got it wired up according to this.

I did however use the Cam1 Magi-/Mago- to C20-121 instead of the Cam2 as written.

So I got a base tune from pimp to try but when i put it in... i get backfires and i cant rev past 2k rpm. I unplugged it and then used the jumper harness to bypass the fic to see if it would work and it did. So what does this mean? Did i wire up something wrong? Or does the tune just not work for me...?

Post some pics, so we can see and help you out

pic of what?

Run the FIC with no tune. If you get the same results its how you wired it up. If it clears up it the tune.

A pic to see if you did all the connections correctly, and I agree with cdydjded

Ok, first of all, what do you mean by this:

Do you mean you wired it up as I said to, but didn't include the Cam2 wires?

Next, did you intercept or tap the crank wires?

I'm thinking that most likely you're running pimp's tune with the wrong settings, most likely regarding the MAF. For example, if you try to run MAF in voltage mode and it sees a 0 in a cell, it's going to freak the hell out. Last I knew pimp was using some sort of MAF clamp, so it's very possible.

cdydjded is right though. You need to put in a blank tune and see how the car runs. The fact that the car runs fine with the bypass indicates the tune is PROBABLY the issue.

I intercepted the crank wires and yes I didn't include the cam 2 wires.... Should I have used them?

[cdydjded]

Yes you do have to use the cam wires.....

[Yoda]

I use them both? There is no cam 2 on the ECM printout...

[Focus_Sh1ft]

Nooooo, you don't use cam2 because we only have one cam position sensor. There should be four right? You need to use + and - for cam1.

You could always try tapping the + crank wires instead of intercepting since it worked for me. Just go by what I PMed you.

[Yoda]

Ok will do that now

[Yoda]

Ok so it started up now. Just alittle sputter at idle every 5 secs

Do you still have O2 sensor hooked up? That tune will not prevent your car from hitting high rpm. If you continue to have problems call AEM they are extremely helpful and really know their shit. Also go to their web sight and download the latest version of FIC software to load in your FIC. My FIC would not communicate with my lap top. It was a software problem. Both cam and crank sensor wires must be attached. Also solder and shirnk wrap everything or you will have big headachs.

On page 13 of my long turbo story, their is wiring instructions from Focus and I posted a ECM connector pin out photo from the toyota wiring diagram.

Thanks guys got it all sorted out and its up and running. Pimp you tune is nice just need to figure out how to adjust for my larger injectors. To think I was afraid of wiring. It's really not hard once you kno what to do. So much knowledge I have gained thanks to you all. I feel I could turbo anything lol

To think I was afraid of wiring. It's really not hard once you kno what to do.

To change injector size, highlight the entire map, right click, then injector size change. It's pretty self explanatory from there. Best results I got were stock at 200cc, 1ZZ at 250cc.

THX!
