thanks a bunch guys,

now to get some injectors....

wow, page three (in the ECU tuning section)......

Question:

When I connect to the EMS in my car and I go to the fuel table, on the left there's a "Load Breakpoints (PSI)". When the car is off but key in the ignition and I'm connected to my EMS, this acts more of a TPS (throttle position sensor). When I have my foot off of the throttle it's at -14.69 psi and depending on how far I push the throttle it goes up/down.

Does this mean that my map sensor doesn't work? I assume that it should read atmospheric pressure when the engine is off correct?

I'm having troubles starting my car (my base timing won't sync properly, it keeps "walking") so I can't tell you how it acts with the car on.

thx for any help

i don't know exactly why... but mine does the same thing... you think that if the TPS has power and ground that the map sensor would too since that is where it is wired in??? maybe the egrt circuit needs the engine running before the signal will reach the ecu???

when the car is off the map sensor isn't sending a signal... so the load is determinded from TPS vs Load breakpoint table... if you start the car it will turn the map sensor on (assuming you have it wired correctly) and load will be the normal boost/vac readings...

you have to tick a box somewhere
setup- sensors- map sensor- speed density i think

Now that summer is almost here I went to use my A/C. Nada. Magnetic clutch seems to not be engaging.

Someone mentioned to me that the AEM had a problem with that. I didn't see anything obvious in AEMPro. I searched this thread and found one generic reference (but no help).

Anyone know where the A/C is being held up by the AEM?

Thx

What in the advantage of using the AEM Dual Channel UEGO Kit verse the Single Channel UEGO Kit? Is it worth the extra money, when the gauge can only read one channel and you have to have two gauge to read both.

Iv been reading up on this thread for the past two days. So if this is covered somewhere in here i am sorry:has anyone had any issues with running the hot wire kit and a kenne-bell bap? just installed the AEM and havent even wired up the sensors yet, but was curious if there were any issues. Also looking for a start up cal. penguins--sorry didnt know you werent doin them anymore for free(email I sent a few days ago)hoping to find someone with similiar set up.

I found an old one in this thread but it was the 1.11v--can you upconvert without losing info?
any help is appreciated.

I know this may seem somewhat basic for this thread but I didn't find much help searching the forums or the thread or searching AEM's forum. Anyhow, I cannot get my laptop to connect to my EMS. I've read all the information in the user's guide as well as what info I could find online and yet it will not connect. Am I missing a step somewhere along the way? Is my EMS bad?

Here's some basic info:
Old laptop, Pentium 933 running windows XP.
Serial port is COM2 (COM1 is not available on my computer for some reason)

Tried connecting via the serial port and would get nothing but the querying box while saying the ECU is offline.

Then, I purchased and tried a USB to serial adapter cable (not a Belkin) which has had no luck. I tried going through it as a USB cable which just quickly gives me an error saying saying something to the effect of unable to connect or ECU is offline (I don't remember exactly what it said). I also tried going through the adapter as COM5 as that is what it was installed as. This has even more fatal results. It queries for a few seconds and then gives me the blue screen of death.

I have since gone back to trying to use COM2 but now it doesn't even give me the constant query anymore. Now it just gives me the error of being unable to connect shortly after trying to connect.

I have tried every thing I can think of and have yet to get it to connect so that I can get my car running now that I've installed the EMS. Obviously there has to be something I am doing wrong or there is something wrong with my computer. So, does anyone have some info that may help? I tried calling AEM tech support but all I got was thier answering machine (it was about 30mins before closing time on a 3 day weekend so that may be why).

Take a look in your Windows Device Manager and try to figure out what hardware is mapped to what com ports. COM2 may be your modem or something.

If you've got some fax receive software or something along those lines, try disabling it or change its config to point at the modem port if it isn't already.
