Does anybody know how to wire up the aem to the 2.2 ecu?

 

do a search im sure you can find something

 

would it be better to run stock sc injectors with the aem fic or would you want to keep stock?

im ready to put it on now and was wondering what to do

 

I have stock SS injectors and I'm planning on installing them with my FIC.

The FIC can change the pulse of injectors so it will let you run bigger ones for future mods.

 

yea, i knew that from reading up on it but i was curious as to if it would be better than having the stockers in

 

what are you needing larger injectors for? if your mods do not call for more fuel there is no advantage to installing them.

also, check the 2.2 section, there are a couple threads already up about the FIC.

 

lol i got the PO171 code today... fuel lean lol maybe i need the bigger injectors...

 

Sorry I'm not real familiar with your setup. Are you using the AEM FIC? Adjust whatever map you are using (o2 I'm guessing) to add fuel at those points where your fuel trims are exceeding +20. Should fix your p0171. The closer to 0 you can be, the more accurate your tune and the less of a chance of hitting any P0171 or P0172 DTCs.

I would see how far you can go with the stockers. Once you hit the 90% duty cycle mark I would upgrade.

I imagine you are using a scan tool to scan for fuel trim values when tuning. You can take the commanded fuel injector pulse width and plug it into any online calculator to determine your duty cycle. Also note what RPM you are at when you hit the highest pulse width.

 

i have a friend who has one that i was going to use. will the fic get rid of the p0171 that ive had for 17 months now? check my vbgarage for what else i got.... aem wideband, datastream, n a few other things that involve a/f ratio

 

It will get rid of the code if you program it to add fuel correctly yes.

Our stock fuel injectors are only 24 lb. I have 32 lb injectors from the SS waiting. I am installing them regardless of duty cycle of the stock 24's.

I forgot to mention I have a supercharger to install too. That might make a difference.

 

^as of right now im not running it... i might in the future so i can tune it... i did get that code then the PO 420 so i know its runnin lean... im gunna buy a WB before i do it though

 

gettin ready to install mine now and got an elm 327 scan tool to help with tuning... it is pretty amazing tool

there is some info on it.... whats anyones intake of it?

 

Woohoo, old school hyperterminal data logger. Actually a huge pita to setup and log with but works on damn near anything.

You can use pretty much any obd2 data logger out there. Even HPTuners own scanner will datalog pulse width and fuel trims for you (you may find it easier with a commerical data logger than the elm unit).

I don't live too far from you, you should bring the car out to a Pittsburgh get-together sometime. I'd love to see it when you are finished.

Here's a cool little unit that uses the elm circuitry to interface into a PDA http://www.eng-tek.com.au/product_in...products_id=66

 

yea, i live in north huntingdon, like the irwin exit on the turnpike n my gf lives right off of carson street in the south side so im there all the time. maybe when i get everythin n get it ready well set up a day to meet

 

I have the pinouts

 

will the aem work on just a stock motor, with intake and exhaust... want to get cams soon, but i am getting the aem fic first, could i install it and do a little tune on my car to make it run a little better...?

 

Yes, I have it on my car without F/I right now and it runs fine, you could tune it if you'd like but there isn't much point if you are still building the motor.

 

can you wire the aem wideband into the aem f/ic???

 

anyone know about the wideband???

 

I have a wideband installed also. No issues.

 

its wired into the aem f/ic? i was pretty much wondering if thats what the data logging wire was for?

 

It's wired into the Analog input designed for a wideband.

 

I got a innovate wideband it works awesome and really simple to setup

if you wire the wideband into the aem if something goes wrong with the aem and it goes into the lip mode you've just given up your biggest tuning help. and then you basically have to tune in the dark the AEM FIC comes with a safe mode which engages if there are any issues with the engine, so before you can seriously damage your engine it cuts the power and then tells you what caused it once plugged into the computer.

 

I've never read about this "safe mode"

can you elaborate or maybe link us?

 

The AEM FIC is equipt with a "safe mode" so to speak unlike Mega squirt the FIC when pushing the engine to its limits and the AEM detects that something is about to go wrong it converts back to the stock tune so that the engine does not basically break. It also logs the data about what has happened and it also saves the previous tune you had it on so that you can make minor tweaks. This system is much more user friendly than any other system out there. But once this happens you can only drive for so many miles because if your going forced induction you'll be running to rich. And because the FIC retards the timing for you "no bent valves". One reason why i said that wiring your wideband into the FIC makes it less accurate and your supposed to use your wideband in the process of tuning. Your tuning and tuning components should be two separate systems.

I'm currently looking for the link once i find it i'll post it
