Greddy E-manage

[daxter]

Hey, I've been doing a bit of searching and still unsure of which piggy back I should use.

Car is automatic 96 R33 GTS25t

Mods:

- Full 3" exhaust system with split dump pipe

- 600x300x76 FMIC

- POD filter with cold air box

- HKS FCD

Parts sitting in my garage about to go on:

- Garret T04 turbo

- New turbo manifold

- Fuel pressure regulator

- Walbro 255LPH Fuel Pump

So what piggy back would give me the best performance on a automatic with these mods?

I can easily get a "GReddy E-Manage" would this be perfect?

you do realise that there is about 20 different versions of the Garrett To4 turbo, ranging from 200hp to 1000hp?

and why the fuel pressure regulator? Are you planning on running more than 350rwkw? If you are thinking about pushing more through the standard injectors - forget it. You'll kill them and your motor very quickly.

Simple and most effective solution is to run the standard FPR and buy bigger injectors.

As for the ECU - look into the powerfc. Its the best bang for buck, and I'm 90% sure they work fine with autos.

yeah PFC and EMU are both good enough for what you want. You could get away with a Blue e-manage kit just.

Sure if you want to go to full semi-automatic.

^^^ had no drams with the 3 or 4 i have done??? all series ones though, maybe the issue lies with series two onwards.

It has something to with retarding the ignition on gear changes, which the factory ecu does but the pfc does not?

I'm no expert but this issue has been covered in pretty great detail in the stagea section (mostly autos). Basically there are full replacement ecu's like the E-manage or powerfc but none of these can give you the level of protection for your gearbox and engine as the stock ecu. The stock ecu apparently has mountains of logic for different scenarios and different situations in order to keep your auto box running smooth and your gear shifts smooth and quiet.

Remove the stock ecu and you lose all of this and end up with a car that drives harsher and is likely to reduce the life of your auto box (worst case). Not saying it will break shortly, just that it may not last as long.

I'm just passing on what was discussed on the stagea section, but I've also heard from other sources that your car's stock ecu has a LOT more complex programming in it than any aftermarket ecu. A lot of it is to do with making your car safe and comfortable to drive every day, so whilst you can get away with a replacement ecu in manuals and you can get an auto running with one, there will be some compromises.

Unless you want huge power, you can usually get away with just a few piggybacks like Apexi SAFC and Apexi SITC. These wont give you anywhere near the tuning capability as a replacement ecu but on the other hand your car will start fine every morning and your auto will drive perfectly with no headaches. They are also easy to adjust by yourself if you happen to add or remove more performance parts and upset your tune.

At the end of the day, you just want to drive your car, so dont get too worked up about which is the ultimate best solution. Work out how much power you want, how much is realistically actually useful on the road, and then work out how to get there safely and reliably. Chances are you will be quite happy with just the bigger turbo and a bit more boost and with the mods you've listed plus the turbo etc you will be fine with the piggybacks. Its a compromise either way but I'd rather compromise a little bit of tuneability than driveability.

See the mods in my sig - i've been running with just a apexi SAFC for over 12 months and it works beautifully. The SITC will give you a lot more control and will reduce your lag, although even without it you can still advance your ignition timing a bit. Only cost me $150 to tune it too.

Would those auto shift-kits help the cause a little??

Also, aren't the GReddy EMB's and EMU's actually piggy-backs themsleves???

[daxter]

Thanks pixel8r, that was really helpful, I'm after 200kw at the wheels, if I happen to make more power then that's a bonus

Apexi SAFC was another piggy back I was looking at, as I'm after something to ensure there is a good A/F ratio going through the engine with these mods.

Thanks for all the reply's, given me something to think about.
