Is there a way to go about tuning a 350Z with a Stage III Stillen S/C? I know there is no way to plug into the unit they supply, but can it be tuned at the original ECM and still have an effect or would the Stillen module over-ride any mods made there? Am I making sense? I am kinda new to this........

 

go buy a apexi afc 2 ..($350)..thats the cheapest piggyback system and it works great...have it on my z.....i have procharger though....go have it dyno tuned.with the afc..they can answer all of your questions...

 

safc cost about 250 new and no there not that good if your going to go F-I do it right honda guys dont even use safc for turbo's and superchargers^

 

you can take off the stillin comp, and use any piggyback system, i doubt it will make a big *** difference.

 

Stillen uses the Split Second unit.We have the software for it.The Split Second allows for timing retard.The S-AFC does not.If you take off the Split second and use an S-AFC, your motor will blow in short order becasue of lack of timing retard.The thing about it is that the Eaton SC on the Stillen kit runs very hot and the liquid to air intercooler really leaves alot to be desired.You need to retard that timing or a catastrophic engine failure wil occur.

 

So basically are you saying that I should leave it AS IS and do other mods to increase horsepower?

 

You might be able to increase the power a bit if you do some minor tuning with the Split Second.However you have to "break into the box" which might void your warranty with Stillen

 

With stage three there is no warranty anyway... Are you running stock injectors?

 

Yes i am runninn stock injectors. Sholuld I increase size and to what size should i increase to and what else is in order if i increase injector size?

 

HA ! none of these guys know what there talking about

 

have you asked stillen?

 

I have alreeady cracked open a Stillen box and connected with a laptop so your are right I do know what I am talking about As a matter of fact I have thier file on my computer right now and I can tell you this much, they retard the timing quite a bit as the car goes under boost.About 1 degree per psi.

 

The stock injectors can handle what is needed for the Stillen S/C kit. You might want to try a new fuel management system. Stillen uses a 7th injector that is very inefficient, it even flows fuel at idle? Jim Wolf does have a FMU that would work better if you have someone in your area that can tune it once installed.
