I'm probably gonna go up to 17-18psi on 94 octane pump. And eventually run more psi when I have the water/alchy injection installed, but that's not important. I just need to get it running first, and then worry about including it later.

So are you telling me that if I buy a 5 bar map, you'll send me 2 x 3.5 bar map sensors? That could possible work out, as both myself and IMZTT will need two MAP sensors.

Thanks! Yeah, my injectors are low impedance. And yes, I do have wideband (PLX M300).

pengulns2001 · 06-15-2005, 05:43 PM

ok well you need to select that wide band.... please verify the map i sent you goes only to 22 psi before using it, i want to make sure i sent the right one

yes thats exactly what im saying i need the 5 bar and that would make my 2 3.5 bar sensors useless, ones brand new the other is currently being used but is perfect

Yup, the map goes up to 22psi. I'll talk to IMZTT and see if he wants to do this trade.

Slava...unplugging that connector to the ECU works. Thanks for your help!

After 3 hours of getting to Keyless entry module and testing different things...the solution to keyless entry problem is to disconnect the smalles plug from the ECU. it does not used for anything (stock), but can be used for optional switches etc. Not sure why but something there prevent the module from working correctly.

Ok. Tunning question(s).

First, should i have o2FB to manage fuel up to max boost or is it better to have it stop at 3psi for example and then have solid fuel map to keep the AFR stable ( not that i do not have to have solid map regardless).

and second.
I would like to have high >14 AFR on the low loads , crusing...
Is it better to just tune the vacume and low boost fuel map to delivery right AFR (+02 FB) or
have throuttle/fuel correction to take some fuel between 0and - 50% throuttle?

Sounds like throuttle/fuel method is easier to configure but i am not sure about final results.

DEFINTELY stop the O2 FB as quickly as you can... I just have it setup to compensate for any climate changes for my off-boost and idle.

the second question is kinda split...
If you use boost comp... you will ALWAYS have to do throttle/fuel correction to take out some fuel in the middle. If you do a complete grid, it's not as mandatory... as you control most of the a/f mixture at each particular point.. But it's definitely harder to tune when you have major condition adjustments like climate or modifications... point-to-point tuning leaves no gray area for the computer to flex it's muscles -- aside from the O2 FB.

Now when i have pretty stable fuel map how do i go about adjusting timing?
Advance the timing until i see the know does not seemed like a good idea.

I noticed that timing makes a big difference. Even on stock ECU i felt the difference between go WOT and letting off the throuttle. Letting off the throuttle felt like accelerating more....I thought it is my imagination. Now with AEM i noticed the same thing and after looking at the logs i can say that car accelerates faster with 8PSI and 24degree vs 13psi and 14degree. Map advances timing due to the lower boost value.
So how do i safely play with timing?

I use boost comp , that helped to get base fuel map. But now i am adjusting each fuel cell. The boost compensation just adds fuel based on the boost comp graph which does not have to be linear...

Pacman about how long would it take to tune the AEM EMS on my car on a dyno?

pacman3000gt · 06-21-2005, 10:18 AM

dyno?

I think it's much cheaper to tune it out on a street/highway.

Legally... of course... you can tune the EMS on a highway and still be within the legal 'speed' parameters.
