96 and later have the boost sensor on the intake

[Boostaddict]

Yeah, that adapter is only good for the newest of the 3/S's. The less desirable thing about putting the map sensor directly on the intake manifold is the heat will not be kind to it in the long run, and could possibly affect calibration values. Lots of people do it though and only some report better/different results with having it somewhat isolated (like with a very short piece of hose).

yea i guess it would only work for newer 3s', sorry they use them for their evos and said they have had great luck with them

but it does look alot cleaner than mounted on the back fire wall i think if your going for neatness! as soon as i get car back ill post pics!

Well I'm here for some help from the guys that have been tuning for a while. I have the log/cal before the FIAV delete, and after the delete.

I have labeled them accordingly for you guys to look at. After the delete, my whole map has changed. So I know it's not optimal. Let me know what you think. Please be as critical as possible.

What exactly i need look for? what FIAV? nothing comes to mind.
just general map comments.
1. fuel/boost correct is not linear
2. Baro fuel corr is not needed.
3. injector phasing is not setup right.
4. weired fuel map unless you just started.
5. you are using stock injectors, need to optimize fuel map.
etc.

you need to log more parameters.
your test runs needs to be consistent. for example floor in 3rd gear from 3-6k.

3.5bar AEM MAP sensor, but I'm seeing load range in your fuel map of only -12psi to +22 psi... You should extend that to match the range of your sensor.

Like Slava said, you MUST get that Boost Correct table fixed. You are going to blow something up with it all wacky like that. It should basically be a straight line from -100% at 14.69psi to +250% at 35.31psi. You are at like +270% at 22.8 psi, which is way whacked.

Don't worry about the injector phasing for now. It'll work fine with the base setup that's in there. When you get your fuel tuned properly, then use FWombat's Excel spreadsheet from the AEM Forum (I think there's a link to it in this thread) to design a proper injector advance table.

I'd start out with a map that's more properly set up... This one has some "issues" in it.

if you want a map to start over with post all your mods and ill write one, i actually like to use -12 to 22 psi load break points for better resolution if your not boosting higher why have higher breakpoints but that map has serious issues, the boost comp being the worst

[MadMax IL]

I would really appreciate a map to get me up & running.

I have DR650 turbos. HKS intercoolers with 2" piping.
Supra fuel pump "hot wired" with aem fpr, RC 750 injectors.
GM 3 bar map sensor. AEM air temp sensor. AEM UEGO dual o2 sensors.
I use only Israeli 99 octane fuel which is probably a bit less by US standards, but still the best pump gas available here.
Please include the boost comp also, Ive read & read & read and I guess my english just aint up to par - cause I still dont get it.


Also, a little question in logistics.....after I hook up the EMS I have to make sure with a timing light that the engine matches the AEM - now, seeing that my friend with the light and my other friend with the garage where I will do the install are in two very different places.....can I check the timing a day or two before, jot down all the appropriate numbers - go to the other place, install EMS entering the numbers from before - then drive carefully back to #1 to make sure its still the same?

If you aren't boosting higher than 22 psi, why bother with having an AEM? Hell, that's where the fun just gets started...

What happens if for some reason it does boost past your load limit in the fuel/timing maps? I hope you've got your Fuel Cut Load parameter set lower than the upper edge of the fuel/timing load axis. BAdAzZV8 doesn't. Not sure I'd want to try that experiment. I guess you would just have to hope that it uses the top-most load row in your map and be running boost compensation to at least keep throwing in more fuel as the boost goes up.
