Fuel Injectors

[murcielago]

well I'm not planning on splicing into ECu at all, not going with me. what do you guys think about this:
But if i have to i will....

AEM FUEL IGNTION CONRTOLLER (F/IC)

Well the tell tale truth of it is this: In order to tune a car.....any car....you have to mess with the ECU. Either the wiring that goes to it, or by chipping it or reprogramming it. Your only other alternative is an AEM stand-alone system...but they are VERY expensive.

You can't be afraid of it if you want it to work. If you pick a path and learn it, it will be much less intimidating to you.

I see. well ill probably just go with the SAFC then and splice into the ecu nicely done..
Thanks..

If you just flashed your ECU you wouldn't have to splice anything..
If you're dead set on using archaic technology with limited applications, proven to be less effective and nothwere near as good for you or your car, I can't help you.

Just run a Safc, gm Maf and translator. You can tune off that if your not wanting to spend much money. I would get bigger injectors then your talking about running too. I'm running 880cc with that setup with stock fpr with no problems.

This is what im thinking on doing, Run SAFC or maybe( AEM FUEL IGNTION CONRTOLLER (F/IC) but not "Gm Maf and translator". im goign to stay with my stock MAF, and run 580cc or 550cc, with a AFPR..

why dont you have AFPR? with stock your not running rich or anything?

hey you have help me alot man, im still learning here. im just looking for the ebst for me, nothign crazy, if i can get something to adjust fuel with out havign to splice for not big cash than thats what im goign with..

What do you think of this:AEM FUEL IGNTION CONRTOLLER (F/IC)
?

 

[Absit]

For the final time, the best, cheapest, and easiest option for you to tune (starting with scaling injectors and learning to do more as you go) is flashing your ECU.

And I think the AEM F/IC is an absolutely horrible solution for our cars. It's $400 to do 1/3 what the $200 OpenPort 2.0 cable can do for you.

I don't need it, no it stays right where I put it.
Why don't you get bigger injectors? You know once you start upgrading you'll get hooked.
You can fine tune with the translator.

Absit has said much of what I would say on the topic of tuning. In my opinion the SAFC has no place on a DSM that is modified today. The technology is more limited, less safe, and less useful than almost any other solution out there. Furthermore, I often see members suggesting that because the SAFC does less it is easier to use, and this is absolutely not the case.

It has been said a number of times already and I will say it again. An openport 2.0 cable to reflash your ecu is your best option for low cost and lots of features. There will be a fair amount of reading involved but it will be easier in the long run than getting a good tune out of an SAFC. Also, I did not see much discussion of the fact that you will need a wideband in order to safely tune your car, and the fact that an openport cable or ecmlink have the price advantage of not having to purchase a separate logging device.

 

[murcielago]

Thank you all for the help really..
i Made up my mind, going with the reflash because i will be able to play more with the ecu later on...

Thank You All
Murcielago..

if any of you have experience with reflash let me know how it really is from your point of view and is there any dangerous things i should do.. remember for now ill i may want to do with fuel regulations and maybe timing..

 

[Absit]

Yes, there is one dangerous part, if you lose voltage in the middle of a flash you can brick your ECU. I never flash without a charger hooked up.

haha. ok i see. now let me ask you this since you've done this.

when i hook this thing up will i see everything stock? all i really want is to make my car idle and drive straight(good). no roughness remember i am mostly doing this because im changing to higher injectors, right now im going to buy 560cc(evo-9), and then later go higher.. with this re-flash will i be able to just tune that? with-out touching anything else, i don't want to really hurt something on my engine, maybe also play with launch control if possible..


Please let me know you can even PM me.. well anyone.. Thank you...

also i was reading on the thread on vfaqs here on the site on the flash but it seems complicated for me for the moment, I'm new to this tuning world. So please let me know Thank You!

also what do you recommend for me to buy for this, do i really need the 3.5 map sensor? and where will i be tapping this too?

 

[Absit]

Yes, you can tune JUST for new injectors (injector scaling and latency) and not touch anything else. In fact, ECUFlash has user level modes that won't let you touch much more than injectors at the lowest setting (default). There are some big threads around for it, time to search.

cool ...

now ill have a AFPR, with that ill adjust the psi to 43 on idle. so i will be able to see the pressure from the AFPR on the gauge that will be on it, what exactly i will be adjusting with ECU flash? since i already adjusted the psi with the AFPR?


Thanks for the reply's btw

 

[Absit]

It's time for you to search and learn to tune.
Also, that's not how you adjust the fuel pressure, you do it with the vacuum line capped or the engine off.

Search time.

 

[the_mork]

Absit has given you great direction so far and I feel like an echo in this thread when I say that it is time to search but here is the first place to go to read more about what you're going to do http://ceddy.us/

From there go ahead and read lots of threads in the tuning section.

Cool. yes he has.. i just Joined Ceddy.us.. pretty interesting stuff there on tuning.. hopefully everything goes as planned and i don't fry anything..
Thanks..

Thanks to everyone who gave me the advices..
