Well I need HELP again.. Trying to maximize the SC setup
I was gona purchase the JICs but decided against it and now I can spend the cash towards more performance. Right now I am running a 3.125 pulley and a 6:1 disc. I am planning to purchase the MEVI so what else I should get to make it a safe setup? 300zx injectors? jwt ecu? Will I not need the FMU anymore if I get bigger injectors? Whats the advantage? Need advice from the gurus here ;-)
Thanks!
Thanks!

Dixit if he goes with JW ECU he should not need a fmu of any type. JW will program the ECU to run the injectors. Ossamah going w/the injectors and the ECU, game on! you will be one very fast **** and no headaches to worry about since JW dyno tunes the ECU for you.
I told you you was going to get MEVI. "you said NO

we going to go to the track, all of us, and it will much different safer and it will be right on the money. Once you install the FMU, adios FMU. I told you the ECU will control it. Sit back and watch what I am talking about with I believe Stephen max, he just installed this set up in his SCed max.

yeah we can go to that sh!tty commerce since is not that far away, can you hold tight while he breaks that clutch in so we can all go at the same time all three of us
Don t forget I just did that clutch this past weekend in the white max.

That's right. I'm really enjoying it. Before, I was basically untuned running an 8:1 FMU, and having the JWT tuned ECU is like night and day at the mid-rpm range. Noticeably more power even with conservative timing and afr. But that is just butt-dyno results, and we all know how reliable they are.
I haven't wrapped it out to 7.2krpm under boost yet because I am an overly cautious candy-a$$ed old fart, but when I re-install the MEVI sometime this week I'll carefully work my way up into the stratosphere.
Or maybe not. With a 3" pulley at 7.2krpm my blower will be spinning at 51.4krpm, about 3krpm faster than with a 2.87" pulley at 6.5krpm, so I'll be making about 13 psi of uncooled boost. I probably should have stayed with the 3.25" pulley. It might just be FMIC time for me.

What setup do you have right now?

Why are you using a SAFC? I thought the ECU controlled the everything for you

As you said, JWT runs on the rich/safe side.
If you make it to a dyno, you might find some decent gains with some fine S-AFC tuning.
Don't be getting rid of it.

So the best/safest setup for getting the most gain is S/C, Z injectors, JWT ECU upgrade??
Right now I am running the V2 w/ Blitz BOV, MAF between BOV and TB, MEVI and Vortec FMU w/ 8:1 Disc. Running HELLA rich. I'm contemplating my next move and I'm trying to get some solid info on either Cartech FMU/AFCII (or Greddy E-Manage) or the JWT route. Hadn't planned on doing the injectors. If I stick with stock injectors, is the base map from JWT effective? I do plan to convert to 5spd once the A/T bags out. Should I go with the FMU/AFCII (or Emanage) for now and worry about the JWT upgrade after 5spd & injectors? What if I decide I don't want to do injectors?
I know thats a lot of different scenarios but some saged input would be much appreciated.
Thanks in advance.

I don't think JWT has an ecu program for stock Maxima injectors. You might want to call them to be sure, though.
For 9 psi or less of boost, I'd stick with the FMU and fine tune with the SAFC on a dyno. Once you get to 10 psi and over it's time to think about larger injectors so you can run stock (or at least lower) fuel pressure. Just my opinion.

How much boost are you running now(size pulley?) and how much do you intend to push FINALLY? This depends MOSTLY on your final hp goal and secondly on your budget.
The FMU route works, however it's not as safe. Plus, according to StephenMax, the injectors/300Z MAF/JWT ECU together seem to produce better gains then the FMU overworking the stock injectors.
If you can afford the JWT ECU, 300Z MAF, and injectors, I'd go that route ALL AT ONCE. Otherwise, just keep the boost reasonable and save up until you can afford the JWT route.

There is no doubt it is a safer setup.

I did actually talk to JWT and their base + SC map is for the stock injectors/MAF + S/C. I'm running the 3.33 right now and have pulled a max boost of 8.5psi but generally average between 7-8. I do not plan to go beyond the 3.12". It's sounding like I should go with the FMU/AFC or Emanage for now and save the JWT for after the 5spd conversion (and possibly new injectors/maf...not really wanting to fork out the $$ for those). I've achieved the level of "legendhood" I was after so anything beyond what I have now is "nice to have" but not a "passionate desire".

Sounds like the FMU/S-AFC(or Emange) is the best IMO.
Only hard-core boost junkies that NEED 10+psi will require the JWT route.

That confirms some other input I've gotten. Just ordered the 2025 FMU...should be here next week. Then off to dyno Until I start pushing a load more of boost, I'm gonna hold off on the AFC as well. Found out the E-Manage really does it's best on 400+HP. I shouldn't need the AFC till I drop down a couple pulley's. By that time there might be an AFCIII and I'd sure be ****ed to have wasted money because I didnt wait till it was needed
Thanks for the input guys.

I think I'd get a wide-band 02 done when you go to the dyno before you decide no on the S-AFC.
You can pick up a used one for $190 in the FS forum right now.
