Greddy E-Manage or Apexi PFC?

Ok gang.. I realise they are two different applications yet both have a similar job in mind.

Just a little basic info on my mods, I have a 3" turbo back, Apexi Pod, Bleed valve @ 10psi and I'm tossing up between a Greddy R-SPL or Blitz LM front mount.

More likely a Greddy R-SPL.

So anyway I'm looking for a stable Engine Management unit that will be able to support around 250rwkw. My future plans are to get the turbo hi-flowed, bigger fuel pump to cope after the hi flow, adjustable cam gears to bring boost on a little earlier, adjustable fuel pressure regulator to pump those injectors so they don't max out.

Your probably thinking if his doing all this why not get the PFC... well it's gonna take a lot of saving to hopefully aim to get these mods done by the end of the year (Dam poor a$$ office job) and I think once I get the cooler this will probably make the fuel system abit rich and instead of going the SAFC-2 I'd get the Greddy E-Manage.

So can I have your opinions on this? Considering Greddy E-Manage is around $550 and the Apexi PFC is $1450.

Thanks for everyones help!

powerfc is $1100 delivered from nengun. powerfc will do 250rwkw easily. speak to your local tuner and see what they would prefer or what they consider better/easier as they're the ones tuning it. i know nothing about the emanage but have powerfc on my r33. also speak to your tuner for a fmic kit install, will be cheaper than an unfitted jap kit and should flow the same.

I actually don't have a tuner =

I do all my own service and everything I've installed so far has been simle bolt ons.

I'm thinking about heading over to Ice Performance, I had a couple chats with the boys over there and they seem quite good. Although I've heard you have to book a few week in advance, which is a downer.

Have a read of the sticky on what is a greddy emanage at the top of these forums. Gives ideas of the capabilities of it. The emanage can be bought as a direct plug in kit so that you don't need to rewire it. Its probably best to find out what the tuners around there are more familiar with PFC or Emanage, Although I don't expect them to be drastically different!

Power FC is a full replacement computer, there is no comparison between that and an EManage which is a piggy back. If you buy the stuff to get an EManage even close to a Power FC, it will cost more anyway. If you want to tune air/fuel ratrios only, then the SAFC is a cheaper solution, that looses nothing to an EManage. If you are really tight on budget try the Jaycar Digital Fuel Adjuster kit, just as good as the SAFC for 1/5th the price. But you do need to able to read instructions and solder components on circuit boards.:)

what if you can't use the power fc cause my car is auto? The e-manage has one made for my car to run with the auto, so would that be my best option?

The SAFC will do everything that the EManage does in regards to tuning the A/F ratios (as will the DFA). The only reason for choosing the EManage would be to try the ignition tuning option, but I have yet to see a dyno comparison that indicates success from that implementation. And at the same time retain the standard ECU programming for ignition retard on gearchanges in an auto.

So if anyone has done it successfully, please post up the results.

:P

      Mistakes were made, my R34 Story

      In a few years from now, you'll regret that. It'll eat away at you, knowing the truth of the ugly hiding beneath the beautiful exterior... 😛

      I don't think the G2 profile is particularly dangerous for the engine per se, more just are you actually ok with the turbo lag trade-offs? If the answer is yes then go for it. I personally don't think I'd be ok with it because I spend so much time at lower RPMs and I really enjoy the feeling of being able to stay in 5th gear on the highway and just roll into the throttle to get boost. Or staying in 3rd gear on "gentle canyon cruises" without feeling the turbo lag too badly. The 525 pump should be able to run flat out on factory lines but I would bet the pressure drop from pump to regulator is quite impressive. I don't know how much it would be exactly but I've seen figures like 30 psi thrown around.

      It's interesting seeing everyone talk about what level of risk they are happy to tolerate.  Building a GTR always has a level of risk, you could be that lucky guy that drops 20k on the engine build alone and still has the thing go pop on the dyno. Life is fun like that.  The way I see it, the thing is a toy to be enjoyed. I'd be happy to turn up the power on stock motor and limit the risk with sensible tuning and engine protection. If it still goes pop, it is what it is. The car isn't a daily driver so it can happily sit while a plan is made to sort it out.  Given this thing will be a street car only, I really feel it's worth the (relatively small if managed well) risk to turn the power up to around 350KW on e85.  I don't think anyone getting into the skyline game now is doing it out of logic. Surely it is a purely emotional decision so I'm not sure how important it is to think about the engine build logically. The heart wants what it wants.  @joshuaho96 little note for Josh, I run my 525 pump flat out all the time and through the factory lines without any issues. (excluding the melting connectors, that's sorted now. we'll pretend it never happened lol)

      But the Nexus S3 is very expensive and won't be as purpose-built for the application as a separate electronic boost controller :^) More seriously my pet issue here would be that the Walbro 525 running at 100% duty cycle is going to require more FPR than the stock setup can handle. I'm also pretty sure from what I've seen elsewhere you might want to slow down the pump regardless unless you're going to come up with some way of upsizing the fuel lines coming from the fuel tank. Factory 8mm fuel line doesn't actually flow very much if you want to keep pressure drop down between the fuel pump outlet and FPR. If you really want to "keep it simple" I would run only as much pump as you need and source a fuel pump controller to slow down the pump in the vain hope of being able to run stock-style FPRs which are pretty dinky. Or just use the HICAS lines and it should be mostly fine. OP should also really think hard about what profile they'd want out of the turbo. My pet choice here would be the G1 profile rather than anything higher power but YMMV. I already think ~stock turbo lag is pretty bad so I don't want to make it worse. In "gentle canyon cruising" I found that I spent a lot of time around 4-4.5k RPM. I also recommend DIYing labor if you're detail-oriented enough. Costs are high for labor + if you do it yourself you can be your own quality control.

      GTSBoy is again on the money. My actual advice? Sell the car. (really). For what it's worth as is, you can sidegrade into something much better. If you care about function then this is the actual move. If you want a Skyline to perform, set aside about $100K to do it. This is NOT a typo. You will see right away these are two very different mindsets. Realistically we're talking full restomod for any Skyline still kicking around. Have an honest think about which one you are.. and what you want to do, and how much you want to invest in this (with no return).
