Power Fc help!!!

[mextaliano]

Hey fellas,

I have sr black top with power fc.Yesterday i started my car and it started like crap.after checking everything found out that both maps in powerfc were showing 0(wtf).Anyways i reinitialize the powerfc and now i do not have any maps.its back to original factory setting.Is anyone runing the same setup on the sr it will be a lot of help if they can forward both maps.I am not good with electrons.Here are my mods.

vg30 maf
gt2871r
nismo 740cc injectors
cp pistons 8:5:1
eagle rods
264 hks cams(both)
tomei fuel pump

best thing for you right now is to stop boosting and go take it to a tuner...

there was a database of powerfc maps floating around but i forget where and doubt it has the same set up you do....

well, i can help with the maf thing, go to the main screen, select setting, select power intake thingy, select vg30 and select next and that will select the right maf...

I agree- can't go wrong with a professional tune. Good luck!

iirc you add .05ms for the lag on those injectors, then just scale the fuel down in the map if you are just trying to get a "quick running".

If you do the injector scale, it might be a bit drastic, and you'd wrather be rich than lean.

But yes, you need to take it back to get it retuned. Too bad you didnt/cant save your map, but heh you did save a couple bucks not buying a real standalone like the haltech or aem:ughd:

load this up for your fuel and ignition map and enter the proper values for your 740 injectors and your car should run pretty decent but i reccomend you still get aprofessional tune once you get the car running right.

ROFL.

"heh man, you uh... test it first, and let me know if you blow your car up..."

Enthalpy's base map is very conservative but will work to start the car and get it to a dyno and even drive in boost. I used it to start my street tuning and it worked perfectly (ie. engine not blowing up). It's very linear and smooth and a great starting point.

Do not drive on the initialized base map from Apexi as it sucks cows nuts and will surely detonate in boost and bad things will happen.

Oh and invest in Datalogit, it's worth it so at least you can save your maps next time.

[mextaliano]

yup, worked fine.You are rite about base apexi map, it suks nuts.Anyways getting a lill light white somke in the back i will check the compression again.

The Enthalpy map is a pretty good baseline. I use the datalogit to tune mine and friends cars here, and we normally start with his map and punch in the correct figures for the injectors. We leave the water temp correction at default, and I usually go a little more aggressive on the ignition map, we have a little more tolerance here as the octane is a bit higher. If you have an lm-1 with connectivity to datalogit, it makes tuning a lot easier.

My set up is a 20G, 850s and 264. Rev limit is 8000 with just rocker arm stoppers. Another "tuned" set up I am doing is GTRS, 256, 740, rev limit 7500 as there are no ras on this car yet. Other set ups are close to stock. Stock is very easy to tune utilizing RS Enthalpy base maps. I reocommend Scott's maps as a good base to perform your tuning.
