Should I sell my pfc and get a link g4?

[Shakey Finch]

You need the link plug in, afm blanking pipes and exhaust sensor welded in. However the functionality and end result of the link ecu is worth it.

Abbey ms supplied, fitted and mapped the link in my car, and the end result is fantastic!

Ok thanks for the info guys, it's pretty hard for me to justify 1150 plus mapping when I already have a power fc

changing ecu's aint gonna get any more power magically, if its mapped properly in the first place, new ecu aint getting you more, however if u want to have more features than pfc, than u will have to justify the added expense for same power

I took out and FconVpro, an HKS EVC VI boostcontroller and an HKS Knockamp.

I now have a link G4 that resides in the original ECU case and an AEM wideband sensor. It means a lot less wiring under the dash and a much simpler set-up. Plus I can look at the logs myself on the freely available software. The link is running closed loop. Economy off boost has improved, and the midrange overtaking is a joy. I think I might re-fit an afr gauge though at some point just so I can keep an eye on fueling.

The sale of the HKS Kit pretty much covered the cost of the Link and install. At some point I'd like to upgrade to the G4 Extreme and add some more engine monitoring to include fuel pressure but for now it's fine.

Well, the f-con can run closed loop aswell.
I doubt that your fuel economy got better just due to the ecu change. Most likely it has got a better midrange map than you had earlier.
The fcon is quite powerful but it does have the big downsides of not being able to control the boost and you need to buy the software at the "black market ".

£1150 +mapping is a lot of money. I'm sure everybody else is right in saying the g4 is a better ecu, but if you spent say the 1500 aprox somewhere else on the car would it be money better spent?

[nightcrawler]

indeed a lot of money. if you have a boost controller, pfc and uprated afms i think theres no point getting a link ecu unless you want to upgrade. but if you are starting from a standard ecu, afms and no boost controller, i think it would be better going for the link ecu instead.

Spend your money elsewhere IMHO

[wildboy]

Cheers for your thoughts guys, a proper mix of opinions as well!
I'm swaying towards the link really for a couple of reasons ie
1. Lose the afms (which is the way to go it seems)
2. Less boxes
3. Modern software
4. Future proof myself and possible changes to my future plans

Cons
1. Initial cost

I think the fact everyone would get the link if starting from scratch means it is the better long term option.
Got a lot of work on this summer so now is the time to splash out before the work dies off again lol

Cheers dave, but I have haha, wheels,brakes,suspension,body styling all done bar a full respray. Got a load of parts for more power as well, cams,turbos,manifolds,elbows, rebuilding a spare head, twin plate clutch etc.

Car looks a bit different from when you sold it to me!

fcon vpro runs closed loop i run it on my supra.

Yes it does and I did have mine on closed loop for a while but for whatever reason we got some unexpected results, with the map richening up.

It's hard to make a comparison as like someone else said it's the map and the ECU. I'm just happier with more modern and more open hardware / software and I like the way the car runs on the Link.

[Mark@Abbey M/S]

Both the F-con and G4 link need an external AFR guage with a 5 volt output to run
closed loop.

Both systems need external knock reading units to give again a 0-5v output with regards knock noise so both can be set up for full knock control.

G4 link only has 4 coil drivers where a the F-con has 8 coil driver, G4 has full closed loop boost control built it.

Both F-con and G4 can have multi maps , which can include speed compensated fuel and ignition maps with other maps and controlling signals set up. This can be used to control other items on the car like water methanol control , extra fuel pumps etc etc.

The Power FC J-detro doesn't have multi maps/boost control speed compensated fuel and ignition maps . it doe shave an engine noise indicator as well as air flow meter and injector maximum warnings, is very user friendly you can map it yourslef like the G4 can be self tuned; But it does do a good job for it's price.

If it was me if you have any reason to change the Air flow meters on your car I would look to fit a G4 Link , far better system, has many awesome built datalogging within the ECU and even better with a laptop connected. Very configurable will run 12 injectors dry NOS system , flat shift, launch control ( very good when set up especially the advance launch control) more than I can remember.

If I was going to fit a Link to a drag or race car or a high BHP road car I would look at a Link Extreme for it's 8 coil driver set up and full internal knock control thou.

Any questions ask away.

Mark,

Have you actually setup the Knock control on a Link?

I read somewhere it can only log up to 50ms!! This is no where near fast enough to setup knock control properly..

Ryan

[wildboy]

How good is the knock control on a powerfc?
