E-manage, SAFC, JWT, Reflash?????
I am boosted and am really wanting to be able to tune my car correctly. I don't feel that JWT is cost effective, I am not sure of the effectivness of the apexi safc 2 unit. and I would like to learn about the capability of the greddy emanage unit?
I "was" Planning on putting 370cc injectors and then turning down the fuel psi. however a good friend told me that by turning down the psi only screws up the spray pattern and the car would idle like crap. he also said that by simply installing the safc 2 it would correct for this from idle all the way to redline.
????????????
I would like to be able to tune my car like my friends do with their mustangs and camaros. you take it to the dyno and reflash the ecu??? However I would like to take the cheapest verse best and find a medium!!!! please give your input!!!
I was also doing some injector comparison. Is 370cc enough???? 3.00 pulley intercooled???? currently 3.33, but having a custom 3.00 pulley made so I don't overspeed the S/C. Please give some input!!
Heres a link to injector selection!!!

If you are going to get the Greddy eManage you dont need to turn down the base FP at all. Just get the Injector harness and let the eManage know your base injector cc and your new injector cc. That will do the trick.
I still feel the eManage is probably the best that we got for the maxima world (short of the $2000 stand-alone haltech offers). Ive done way more than I could ever done. And contrary to all the ***** who badmouth the eManage, A) they dont own one B) like to talk shiet. C) Dont understand what its capable of.

@DixitI'd recommend 370cc, Z32 MAF, 4:1 FMU for SC(5:1+ FMU for turbo), and eManage w/ignition/timing/support tool.
You have a V1 or a V2? If V2, I'm pretty sure since you're not getting the extended rev-limiter from the JWT, you can go 2.87" pulley.

I have a V2 and I think the max rpm is 50,000. With the 2.87 pulley it spins the blower at 6500rpm up to 53900><. a 3.00 pulley only spins it like 50300. let me know your ideas on this issue, I don't wanna blow it up.
Also snybody know about swapping the s-trim to say a t-trim etc...

I agree 100% with Dixit...until there is an affordable and more user friendly user adjustable EMS availablfe for the Maxima Emanage is the ticket. its easy to install and tune and the simple fact that you can just enter the fuel correction and decently run bigger injectors with 0 tuning is great! The only thing I think its missing is "direct" injector flow rate control when subtracting fuel(independent of the MAF) if this bad boy could control injector flow rates directly and still cost the same amount it does... 
man!!
and you really won't need an FMU if using Emanage...370s, 255 pump, and an FPR is pretty much it.

How much does the emanage go for? Basically you need a lap top to program it and dont have to have a dyno to tune it or do you ? Can you get alot more from emanage than the safc?
I Know alot of guys do not like the idea of intercooled s/c but I was thinking of going that way. If I had a 2.87 on a V1 with an intercooler would that put boost around 11 or 12 psi?(runnig 9psi now) If so would that prevent me from having to get j&s or adjust the timing? Providing the proper fuel and tuning I thought this would be a safe set up. Just trying to find the most cost effective way to go faster. I was leaning more towards the s-afc II assuming it was cheaper. Any thoughts on this would be helpful, thanks

You dont need a Z32 MAF if you go Greddy Emanage, thats what the pressure sensor is for
. I would still get the smallest FMU disc to bump up the pressure. You can trim that down using the 16x16 tables. Your friend is wrong as hell. I got a SAFC I, lowered FP and my car idles just fine
. How is lowering base FP going to mess up the spray pattern on an injector
. Once you boost your FP is going to jump up immediately.

IMO yes technically you SHOULD dynotune...running off basemaps defeats the whole purpose. the point is to use the system to improve the performance, sure you can slap it in, enter the injector values and drive, but the AF will still be off. when we did Corey's car it was in the mid/high 13s AF before tuning(got it to mid 12s later)...it ran fine, but that 1-1.5 difference in a good AF can mean the world IMO. use the basemaps for just that a base and a means to get to the dyno, sure you can drive on them for a few days or weeks, but don't make it your final tune.
IMO the Emanage has much more potential than the AFC, but in reality apart from the datalogging, high res, ignition control and injector scaling....they perform the same task equally

You should be using 6400rpm as max and 6.25 crank diameter, which is right at 50K with a 2.87. There's plenty more safety margin built in, but you'll exceed the efficiency range spinning it faster.
I've asked the same thing about going to the bigger trim, but supposedly Vortech doesn't "allow" it.

I can always trade you my 2.87 if you are not happy with the 3.00 after you make it.

Your Incorrect. The crank pulley is 6.50 and with a V2 a 2.87 pulley overspeeds the blower by 2996.52 rpm. That seems far to risky to me!!! 700 rpm I can live with.
the v-1 has a lower rpm with the 2.87 only 50788.33. vs v-2 52996.52

I'm running a JWT - extended Rev limiter, V2, 1-step colder plugs, and because i need to get my Z32 MAF running I currently have a 14:1A/F at 7000RPM.
The blower is in great shape and the car hasn't detonated even once that I or my EGT Gauge can tell. I hit low 1400's on the EGT at full boost, full RPM.
The Greddy may be a solution to making the Z32 MAF work however - that would be interesting to try. Anyone out there running the Z32 MAF successfully on the non-charged side with the Greddy?

I disagree....
The optional pressure sensor is just used to tune past the MAF 5.0V limit, however once you're done tuning, you're back to a boost referenced system, ie once you exceed the MAF it's purely fuel pressure keeping you from KABOOM.
Might as well just use your FMU and S-AFC.

thats the purpose a Z32 MAF right? to tune past stock MAF voltage. In your case as a 5th gen owner what MAF would you use?

Yes, however when ambient temp/pressure/etc. change a MAF will still meter the *ACTUAL* amount of air flowing into the engine so you get the proper A/F mix. A MAP withOUT a temp/pressure/etc inputs, ie original MAF equipped car, won't.
5th gens haven't maxed out a MAF that I know of, yet. TechnoSquare can program the ECU to accomodate a larger MAF, Q45 maybe? Not sure.

I just got a VAFC really cheap, now to find someone to make me a custom fuel rail cheap.
If anybody has the wiring diagram for the SAFC, I would appreciate it. I am looking through the forums now though.

OK - so I still need a MAF solution.
I have considered using my Cartech FMU with the Stock MAF and JWT ECU to add Fuel Pressure when I get above 10PSI.
Would that work?
Thanks.

as for the fuel/ignition issues...I'd ditch the VAFC either now or later on and go with Emanage. kill two birds with one stone since it'll basically take care of all your current ans future needs...fuel, ignition, MEVI activation(only if there is a way to utilize the vtec activation on a non-vtec vehicle), MAF swap, etc. ...IMO do it right the first time and don't go cheap as far as your EMS. you'll end up saving money in the end eventhough it seems you're spending more...I've gone through that several times with both of my cars.

thats where I'm not too sure, so don't take that as a guarunte. but a simple RPM switch can solve all that anyways.me/Corey and Dixit(not sure if any others) succesfully had the timing functions running using the diode method...this method won't allow for advancing, but I was able to pull 1* successfully throughout the map and the loss in low end was noticable, so from my understanding its fully functional. albeit a CEL for something ignition related, car ran fine with the timing harness with no burnt coils.

I didn't say they don't exist, just haven't seen/heard any but a few are in the ball-park.
Until someone finds out when the 5th gen MAF is maxed, I'm not assuming it's the same as a 4th gen.. I'm sure Deac's tuner would know, since he has the fuel/hp to find out.

Without the injector harness, the eManage will only be able to control fuel through MAF conditioning, ie same as S-AFC.
You'll want the injector, ignition(needs modification), and support tool cable minimum, however depending on your HP goals, the MAP sensor might be a good idea also.
The eManage is working fine on boosted VQ35s and at least a couple VQ30 Maximas. I'd get it.

you only need the injector harness when adding fuel when using stock injectors or datalogging IDCs...other than that you could get away without it if your goal is tuning down bigger CCrs (ie-370s, etc) which most likely is. but I mean the injector harness is what, $30 extra, big deal...just buy it!!! but no its not necessary for your application...
injector harness or not Emanage ONLY subtracts fuel via MAF manipulation...its just a big *** AFC
