Greddy e-Manage vs Apexi PFC

[400HP]

What are peoples thoughts on this. Obviously the PFC is a tried, tested and trusted solution for GTR's and skylines in general.

Althought the PFC is a full replacement ECU and the e-Manage is a piggyback system they seem to serve the same purpose.

e-Manage is Trust first ECU. Too many if's there.

Also with piggyback systems you cannot go beyond certain limits with mapping. So if your after big HP, forget it.

1. PFC is a full ECU replacement. Much better than a piggyback.

2. An ECU/piggyback is only as good as it's tuner. Who do you know that has shown good results from an e-Manage? Actually... Who do you know what has had *ANY* experience with an e-Manage?

None.

A PFC is again only as good as its tuner.

If you after big power... and i mean big power, or want really good tuning, computer such as the Motec M800 do the best job by far, but often over kill for what your after.

Ahh...sounds like you don't know what you are talking about.

Trust have a 1200+HP RB26 with this piggy back(check out the e-manage web site-- its in jap tho').

Why don't you go check out this link to find out what the e-manage does and does not do before you get all "beyond certain limits" on us?

Please note the reasonably large 16x16 ignition and fuel maps and the abillity to run a MAP sensor in addition to the AFM once the AFM's range is reached.

Did someone say data logging? On my very own PC?

There are plenty of e-manage users in Japan and the US who have highly modded cars making lots of HP. Australia is not the only place in the world that modifies cars you know. Come to think of it, we are probably the most backwards technology wise given the huge number of 'trevs' we have.

Don't get me wrong, the PFC is very good but, look at the what the e-manage really offers for the $, if you can't tune one of these you have to be a shaved monkey.

Power FC's (20x20) 400 Map points makes e-Manage's (16x16)256 Map points look weak and crappy in comparison.

I'd rather nearly double the tuning resolution than the ability to run MAP instead of AFM, which is un-necessary unless you are chasing 600hp+

Well, your right about me not knowing about E-Manage. I figured that the thing was like a Unichip but better since it was a piggyback system.

Still, doesn't E-manage intercept certain signals and sends out different signals?

[400HP]

Andrew - I agree that the PFC is a full ECU replacement which is only good if you're going to be chasing big HP which most people on this thread have agreed. However for amildly tuned package of up to 500hp its probably not necessary.

My decisions is that for me and I'm sure for most people NOT building a 1000hp GTR the e-manage seems to be sufficient of the job. It has the features I was looking for in the PFC at only $300US which makes it cheaper than a unichip. It has the ability to run either MAP or AFM (which can be enlarged to Z32 etc).

The 16x16 may look small but really does it matter that much when doing a mild tune? Also it lets you alter ignition timing slightly from the base ECU. I would be happy with this though as I wouldn't need to remap my entire ECU.

In any case it seems to be an issue of value for money. As it costs as much as a S-AFC rather than a PFC with some PFC features perhaps the question I should have asked is e-manage vs S-AFC.

Silver-Arrowz - I believe all piggybacks intercept signals and send out different ones but thats not a bad thing.

400hp

wait till you see the added costs of the e-mange .ie for the loom software etc I believe it will be closer to $1000 au than $600 au

You don't do alot of ECU tuning do you?

Even the old haltech F series from 6 years ago had 512 Map points, thats 112 more than the PFC . How many of those points do you think you need to have a nice smooth idle and responsive mid range? Answer less than 256, especially when you have another 256 ignition maps.

Programing in 400 map points one by one is for those who like to watch paint dry or run very large HP track race engines, then again I would go a Motec over a PFC it has many times the resolution of the PFC, by your reasoning the PFC looks very weak and crappy next to it.

Whats the point of argument?

They are both good street performance solutions, capable of producing large HP, the e-manage offers newer more affordable tuning, however if your tuner doesn't do them the PFC is a great option. At the end of the day the tuning of these things can cost alot more than the hardware.
