what does it mean if emanage is pre-programmed?

 

That it is specific for a certain app.

 

I tuned my emanage myself =oP LOL not perfect or anything but I did.
and the only reason I did anything to it was because when i frst install my turbo, it was running way too lean
so we 0 it out to b safe. then it was running way too rich and I used wha tI thought was common sense when tweaking the emanage. + meaning more air so i tweaked them all to the plus side and it seem to fix my bogging. so yeah I tuned my own emanage hahaha. now I'm waiting for the pro to do it once i get my IC pipings
btw its currently emanage blue, the pros will tune emanage ulti =o)

 

you can dyno your car w/o an eman but you can not tune it. the eman is going to plug into your stock ecu so it can change the output (the tune).

tuning + eman go hand in hand - and you use a dyno to tune the car - then hopefully the tuner takes the car out and puts it on the road and checks the tune because real driving conditions are different then dyno conditions.... so that helps also. OR if the tuner has a mustang dyno that will help the cause.

 

To answer the original question, Engine Management allows you to get more power as stated, but it is a necessity for forced induction systems to make sure that the AFR is not too lean, which can destroy an engine.

The way that our cars are setup from factory try to keep the AFR at around 14.7:1 which is supposed to be the most efficient for a stock car. Forcing more air into the engine with a turbo or supercharger with that AFR will most likely cause pre-detonation and blow a hole thru your engine.

Only problem with the E-Manage/Ultimate and Unichip is that they only change the wide open throttle AFR (pedal to the metal and hard acceleration). It can't change the partial throttle AFR, such as normal every day driving. Dezod has a device to compensate for that though.

 

See my Sig for more info on these. :D There's a group buy on these Baby!

 

so we would be running stock afr when we are not flooring the car. so you could blow your motor with stock afr when you hitting boost and not flooring it ?

 

YES. The tC ECU will run 14.7:1 until the car transitions to open-loop close to 3500 RPM's -Then emanage can do It's thing and control the A/F per the fuel map that was loaded at the dyno shop.

Dyno tunes will only address wide-open throttle and open-loop A/F. That is the nature of te tC ECU and cannot be changed unless you have more hardware than just emanage.

The A/F in closed-loop mode will be 14.7 with 370cc injectors and will still be 14.7 with 550cc injectors the ECU will adjust injector pulse duration until the A/F is close to stoichiometric.

Tunning a tC is not the same as a Honda with a MAP sensor...

Not sure about blowing the motor at part-throttle-boost but I have registered pre-knock in closed-loop at close to 3000 rpm on my ODB2 scanner. This is something you probably do not want to be doing long term if you want the engine to last.

Any hesistation or surge as you accelerate is a sign the ECU has detected pre-knock and is dropping the ignition timing to help protect the motor. You will probably not be able to hear pre-knock.

 

omg i get hesitaions and surges.....let me mess with the emanage blue some cuz i got rid of it b4.....*sigh*

 

so are car does have a knock sensor right dang i thought only my friend vr4 had one ...oh yea i just found that out today to when my car bogged and i guess it was in safemode cause my afr leaned out when i installed my fuel regulator but now its runing find. I cant adjust the fuel reuglator .. are car or more complex then honda ahahha!! dam toyote engineering they made are car to good to be tuned ahaha!!

 

Never say it's too good to be tuned. :D Did u know people spend money on tuning ferraris and Porches? :D
