Paul;

My comment about the F-CON being used in the top GTRs in the world was in response to a previous comment that needed justification. I totally agree that it has zero relevance to this case.

"any ecu can make a car go fast, its how well its tuned and of course additional features it has"

Little bit contradictory...

True any ECU can be made to tune a car so it's fast... but as you just said: how well it's tuned and the features. Can't tune a ECU well when it just doesn't have the features nor does it have the tunability.

SAFCII is good; but not for the power you're talking about 250rwkw? Don't think so...

Finally, back on the E-Manage topic:

If you do some research you will find that many SAU people have had major problems with just the INSTALLATION of the E-Manage let alone using it. 666DAN will be able to back me up on this. You simply cannot just plug it in an make it work. I think there was a lot of DIY involved in order to make it work stably.

MAP capabilities? Using the Profec B? Hmmm.... and just take a look at N I B's comment.

F-CON, hasn't skipped a beat~

why do you think the safc cant get to 250rwkw? all it does it bend the afm signal. sure its a comprimise but all of the solutions are comprimises.

i dont see why a particular ecu would be limited to a power level, its just ign and inj values. i see no reason why the safc could not get a customer to 250rwkw. it will be a more tedious to do the initial tune as youll get to a point where it will advance the timing too much and induce detonation, but you should be able to get 250rwkw.

SAFC is a signal bender only with all fuel tuning changes have an affect on timing with no means to sort this problem.If you lean out an SAFC it tells the ECU its under less load so it moves the ECU into a lower load zone delivering less fuel but also more timing often leading to detonation.

SAFCs place in the food chain is basic modded cars only.

As far as I know SAFC is a fuel controller only (+/- 16 points) along a preset RPM range.

Problems:

1) No ignition changes

2) No compensation for bigger injectors (stock ECUs won't even work with bigger injectors)

3) What N I B said...

of course the safc wont work with bigger injectors

the user doesnt need to change injectors

it will move the ign timing around as the afm signal it bent

as the load is moved around, so to are the ign/inj load points

yeah Paul is correct from my exp.

I have run them had not real issues...

max'n out injectors is mod/tune dependant - mine were 95% at 260rwkw...with an EMANAGE...but thats with a better fuel pump...not std fuel pressure.

The emange will run to 280 cos I have done it...But I got a much better tune form the PFC.

I have also ran the emanage and the SAFC in my FTO...low power app with EXACTLY the same dyno after....

Every1 else has posted pros and cons...

Get a PFC or Haltech as suggested.

With the emanage blue... the options all add up, e.g. the software (unless your tuner already has it), the injector harness, etc. You should check out the emanage ultimate if you're looking at going this road.

  • 2 months later...

The Ultimate seem like a good buy with all the harness and support tool provided. Anyway it is nice to be able to fiddle with the software and tuning by yourself, but tuning it wrong is high which let to my friend blowing up his engine on the same day he dyno then when home to alter the setting himself. Most piggy back & ECU should be tune on the dyno then leave it once it's done. I will probably go for an FCon SZ or a 2nd FCON Vpro depending on availability plus i have a tuner who drives a GTT with Vpro too. We are always chasing for power, so buy something that do not limit ur goal for many year to come since the ECU is the brain for everything.

    • A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.
    • The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?
    • So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...  
    • the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
