:bath:
:punch:
I usually end up teaching/tuning, makes it easier as owners can be more hands on with their car, especially if they switch out components.

Re: I need some help with AEM
 

I admit it was pretty hard to learn it at first but after I read the instructions step by step it worked out good for me.

I suggest read the instructions and try it out for yourself first and then when you want to get the system really dialed in, dyno the car. Thats better money spent

but since it is hard to read forums and instructions maybe it is best to get lessons.....:rolleyes:

Re: I need some help with AEM
 

that reading forums bit is a take off of a robert downey Jr. line from tropic thunder, "I don't read the script, the script reads me."

anyway, I will be reading up on this stuff. I need to forget about the car for a while and make some money to pay for the tuning eventually.

Re: I need some help with AEM
 

Wow, I was going to ask a tuning question, but now it's a "why am I so dumb" question. Why is my most recent map that I've been "tuning" on the car not the same as it was just a few hours ago when it was hooked up to the car? I click "save file" whenever I make a change when it's hooked up, but now, looking at it offline, it is absolutely not the same as before. What am I doing wrong that I can't see the file as I saw it before? Only difference is I am not connected to the car.

Re: I need some help with AEM
 

Alright. I figured out my dumbness and here is the latest from my efforts to get this as close as possible over the winter.

I still have some problem with big throttle movements from idle, it goes lean for a second. This is with the engine warmed up.

If anyone wants to take a gander at this .cal file and maybe give a helping hint, suggestion or critique, that would be very nice.


on a side note, I started making a "from scratch" file where I started with a blank slate, and almost got myself into some trouble, but mainly, it turned out to be PEBKAC.

Thanks.

EDIT: I'm just leaving this up to show what not to do. I had the wrong size injectors selected. I have 750's and had chosen 850s (the closest option) back before I upgraded to the v1.19 firmware which now had 750's in the list of injector calibrations. I was trying to compensate for a lean condition and crappy revving from idle with a whole lot of tip-in fuel from dTPS and dMAP, but that just screwed everything up. I have since deleted this stupid .cal file and started over with proper settings, and life is much better now. See below.

Re: I need some help with AEM
 

could it be that I need to adjust tip in for air temp as well Bueller?

Re: I need some help with AEM
 

Yeah, it likely is tip in that needs to be adjusted.

Re: I need some help with AEM
 

well, it is. I meant coolant, not air temp, but even if I had said coolant, I don't know if it would matter, since I haven't even gotten it to tip in correctly with the car warmed up.

Re: I need some help with AEM
 

If I have time tonight I'll peak at the cal file. I need to make a few basemaps for a guy in texas tonight anyway...

Re: I need some help with AEM
 

Thanks, BUT, you should disregard that map. I had spend so much time using it, trying to change it and make it work that I forgot I had some basic settings wrong on that map.

I started with a fresh 1300 MAP.cal file, set everything to the right sensors, correct size injectors (yeah, I'm retarded, but that was probably the main problem), and only set the timing, TPS range and raised up about 3-4 squares in the idle range of the fuel map so it would idle fine.

Now it's at 14-15 AFR at idle, revs really cleanly, almost with no issues whatsoever, and sound MUCH better. Cranks over better, starts faster. Everything is better now. I had been going down the wrong path for so long that I didn't want to believe I could have done something wrong.

Next time the roads dry out a bit, I am going to drive it around, see if there are any major problems (which I doubt) and then maybe think about arranging for tuning. I believe I can get it pretty close myself now.

Re: I need some help with AEM
 

Tropic Thunder FTW!!

Re: I need some help with AEM
 

lol, yeah.

I have this thing down now, it's running really well except I REALLY need an idle control motor, I do not like doing that job myself, but when it's warmed up it idles perfect around 900-950 and it's amazingly quiet at idle.

Next step is using the automapping feature to get the fuel map tuned better. I could have gone out today, the main roads were dry but still some sections were icy, so I decided against that. I need some dry roads, yet not so cold I die from exposure when I step outside.

Re: I need some help with AEM
 

I would avoid automapping.

Re: I need some help with AEM
 

yeah, I tried it today and it didn't do shit so I stopped.

Re: I need some help with AEM
 

Sorry I haven't had a change to look at a cal file. I get internet at the new place on Saturday, so I might have some free time this weekend. Email me your latest cal file you want me to peak at this weekend.

Just send it to my yahoo email. swanny09@yahoo.com
