not sure where this belongs.. but i think it has to do with engine so... i know that this is adjustable fuel maps, but is this a good alternative to a technosquare ecu? because each time i get a new part, i may be able to readjust everything? has anybody had experience with this? what are your guy's thoughts on this? please let me know, as im in the process of buying a whole lot of goodies!

 

anybody?

 

it's good for minor A/F adjustments

it might not maintain the A/F though cause of the ECU adjusting

 

so can this replace something like a AAM reflash or Technosquare reflash

 

it can possibly replace it in that it will adjust your A/F


the TS/AAM flash is really a different thing that lets you
raise the redline
more aggressive timing maps
A/F
remove speed limiter
custom permanently adjusted idle


what are your mods?
what do you plan on doing to your car ultimately and in the near future?
What fuel octane do you use?

 

right now i have AEM intake, and greddy evo2 exhaust... but im gonna get a JWT flywheel, kinetix HFCs and AAM 1/2 angled plenum spacer... using 91 pump gas.. inthe future gonna go FI

 

well it's probably a wash which one you get

the Apexi will always be adjustable and you'll have to dyno to tune it

there is a point where if you start making too big adjustments with the apexi that bad things will start happening

if you go with a ECU flash, you'll probably have to mail back and forth your ECU a few times

When you go FI, you'll be able to sell the apexi
with an ECU flash, you'll have to pay like $150 to get it reflashed to the Lspec or stock unless they do it for free for some reason

you'll need a 2nd car when you're mailing off the ECU

so maybe I'd go with the apexi in your case, but I dunno. It just does one thing and you gotta pay to have it installed.

If you plan on doing part by part upgrades the Apexi is probably nicer in that you can always go and retune afterward - though it'll cost you like $60-100 depending on what shops charge you vs $30-50 for shipping costs for the ECU -and not having a car to drive.

With the ECU flash, the only way you'll know your A/F is if you either dyno or get an A/F gauge with datalogging capabilities because TS or AAM need to see a graph so they know where to make adjustments and by how much etc.

 

It will do fine if you stay N/A. To F/I, you will need something with more adjustment abilities/pull timing like the Emanage. Or you can do a full reflash(timing and larger injectors) and use the SAFC to do minor adjustments/fine tune.

 

is the apexi easy to use? im a newb at all these car things... but i wanna learn how to do all these things... can i these things myself? i would jsut have to make sure the a/f ratio is within the perfect range and im getting a linear increase in power yeah? this is just a matter of adding or leaning fuel at the right points to match the amount of air coming in? is this right?

 

i don't think you'll want to adjust the A/F yourself unless you're on a dyno in which case you can probably just have a guy at shop tune it while dynoing

I don't think it's particularly hard to use though, but you should know what you're doing and how it works for sure before doing it on your own.

the car will run ok being a little lean. The car drives lean from the factory for the sake of emissions

 

Hi,

Make sure its a load based dyno when you tune your car. If you tune the car on a dynojet the AFR will change a bit when you drive on the road .

We are located in Hayward, CA and we got a mustang dyno for any of you that needs a tuning session. In addition to that, I would recommend you guys to get a wideband so you can monitor and log you AFR on the fly.

Thanks,

hmm im pretty close to there... can you PM me more about your services? can i have an adress and a price on tuning, etc? i would be interested in bringing my car for tuning in your place... also would be interested in buying some parts
