Good point. I won't be laying the hammer down til its broken in and on the dyno in the hands of professionals.
You know what really sucks about AEM EMS?

Nate, I would think that the injector size wouldnt matter much, because the 800cc is max flow, I dont think I'll be putting around spraying 800cc's of fuel...
Right?
Right?
The ECU works on % over time so say for example 25% of 800 is bigger than 25% of 440.
It will make a difference.

Jake, for initial set-up you'll need a laptop. You'll need to tell it what size injectors you're running, that you're running a map sensor and how many bar it is, and that you're running an iat sensor and which one it is. Also, I'm assuming you won't be running the stock TPS so you'll need to set that also.
Plus, like Ian said, you will probably want to find a map with a turbo and injector combo similar to yours for initial start-up.

Again I'm not sure of the AEM software but with mine I could "trim" the overall fuel map enough to make it run on any size injector so I assume you can do this as well!
You fire it up and it's filthy pig rich as the map you're using is for different injectors you just lean the entire map down in software by a % ditto if it's too lean.
You're just looking for a safe AF that isn't too lean and isn't rich enough to foul plugs and wash down the bores.

IJ, yur right, yur so smart... 
Grant: Im going to be using the Q45's TPS, but I have a link to wire it to the stock harness... Will I need to tell the AEM that its a Q45 or stock? As far as the map sensor, Im using a 5 bar map sensor, it was highly recommended...
Is there somewhere I can go to see what "similar" set ups they have to get a head start on this thing?

Speaking of AF, the AEM EMS doesnt come with a wideband does it? I should look into getting one huh?
once your system is turned you dont need an o2 sensor. you will need one to tune. The dyno/tuner shop will have one. I bought the aem uego and finally got it set up. It still is not dead on with the dyno WB. the plug & play is to a point. the base map was not the best of tunes. Dont do any boosting till you have a tuner.
I bought the wb cause i will eventually know how to tune this thing but it is complicated which is why it controls everything.
I would think you can use just about any TB. As long it knows the resistance and the values from closed to wide open which you set in the program.
the frequecy of the injectors operation is more important than the size. As long as the aem can open and close the injector properly it doesnt matter what size so much as fuel will be tuned with the WB to the a/f. The injector duty will allow the proper fuel amount. I will use 700 cc and the aem can make them idle and supply all the fuel i need.
I have been told the aem with the boost selinoid can control boost very well. I am contemplating selling my blitz spec r. I will see after all it tuned.
I pulled the pins out of the stock harness and inserted the supplied pins for my map, ait, fp, and egt wires. That way these inputs will have a good signal and not from a questionable hack. Be sure to use shielded wire when appropriate.
I think i will find out that the aem will beat all the other piggy backs or standalones. but as with anything garbage in garbage out (GIGO) so you better have a very good tuner.

Hal is dead on with everything in his post.
I had a bit of trouble keeping solid boost with the AEM selenoid, but it may have been partially due to the internally gated turbo I was running at the time. I'll see what happens with the Tial gate on there before I spend the money on a boost controller.

IJ, thanks for the link, I've signed up...
Thanks Hal... The guy that'll be tuning mine has a pretty good reputation, so when it comes to the tune, Im sure I'll be in hands, its just the initial start up and break in that Im hopin works out... The biggest dicipline will be me not pushing the car, lol... ***Baby steps Jake, baby steps***

Their a good tuners here http://racelinetuning.easystorecreator.net/ located in Ohio. Good luck with whatever setup you decide on.
mine and Hal's tuner is pretty good for anyone in the area. He is a supra guy. So jake, listen to Hal, he can tell you anything you want to know, as he just went through this entire thing.
Where are you guys located? Im in Florida...
Yeah, trust me, I'll be seriously picking some brains here soon... Ive done a few BPU set ups, this is going to be a pretty serious set up... Im not skimping on shit here, I've got that in my head... Hence the reason I've decided to go with an AEM and not try to risk it with a VPC and an SAFC...
I look to you guys, the vets, with experience, to help me with advice and constructive critisism... So if Im 'fn up, dont hesitate to call me on it... Im a big guy, I cant take it...
Thanks guys...

i beleive (i havn't messed with mine cause I havn't ordered the gm boost soliniod yet) you can have a high/low switch.. I think the maps are setup based on correction, it will learn the 'precent' wastegate duty to run x boost.. you just plug in target boost and then you can setup a switch to modify target boost +/- x amount... at least thats what i've read on it..
you'll need a laptop to setup the base map.. its not very hard.. i did it on mine using a 2jz map and adapting it to a 1jz.. there should be a similar 7m map avalable.. just adjust it for your injector size and you should be good to go.. (to break in... well depending how you break it in)... wiring for the IAT and MAP are fairly easy.. nothing harder then a afc install or stereo install or something..
lol the 2 step is fun.. antilag + loud ass open wg + middle of traffic is kinda humorous.. lol..
I dunno how your tuner will setup the map but I boost comp'd. my map. Once you tune it at one boost level its tuned for any other boost level.. worked good for me so far...

Justin, you can do anti lag with an AEM? I heard that was damaging to your motor? right?
BTW: thanks for the info... I cant wait to see your set up... When I bring the car down to Tampa, we should get together...

yea you can do it.. Its pretty hard on the turbo.. combustion happens in the manifold rather then the cyl so egts are HOT (my gauge isn't hooked up atm so not sure how hot).. but can kill the seals in the turbo.. i dont think its really damaging to the engine (aside from the extra unburt fuel maybe) if its tuned.. I dont hold it very long, just playing around..
yea, I'll deff head over, want to see your new setup & car.. hopfully mine will be running as it should then..
