Seriously, if someone doesn't figure out how to successfully use the anti lag funtion I'm going to be forced to use another ecu.

I don't want to have to do that.

 

Hi Lupe (and others),

I am assuming you are referring to the datalogit antilag function? I have tried to get this working in my R33 skyline which runs RB25det powerfc and the latest multiversion datalogit box and it does not function. Have also had another friend with same car and PFC model and datalogit box and it doesnt not function either. The results we get is on gearchange nothing happens, no bang bang, no stutter box, no pro launch, and so on etc...

We tried wiring the clutch wires as listed in the guide (and some notes we found on the rx7 forums) and it still did not function. we manually ran SW3 to ground in a last minute hope to trigger it and it did not function either.

What have you tried it to get it working?
Does anyone have access to the datalogit forums?

I suspect theres a step we are missing or a firmware upgrade or even datalogit app upgrade we may be missing for it to work. I would love to get into the datalogit forums to check for a recent manual, software, firmware but our requets to join have been unaswered (since october)

 

I haven't tried it yet.

I only need it from a dead stop launch. I don't need to use it between gears.

Did you get it working from just a stop?

 

anyone?

 

the datalogit "antilag" is a gearchange only anti lag and not a 0km antilag feature
you could utilise the powerfc pro "0km/h rev launch" function and it will wind up the turbo a tiny bit, but certainly not antilag bang bang style.

on the datalogit user groups there is a confirmed report of the anti lag bang bang working on an evo8 but when it turns on, it doesnt turn itself off, ie: the retarded settings and fuel dump dont get removed untill you key off

ie: it works but its broken severly

 

You would still think there would be same way to get it working. Either through the datalogit or using a MSD system.

 

keep asking around, i'm sure eventually you'll get the right answer.
I don't know how it's done but I know it can be. I imported a car a few years ago from Japan that was tuned by Rmagic. It went through two turbos in 1 months in less than a 1,000 miles, yes it had antilag enabled. I remember taking it for a smog test and at idle it's shoot flames about 8 inches long continually out the exhaust. Cause we didn't know how it was enabled we chanhe the apexi ecu with another one and since then haven't gone through anymore turbos.

 

lupe - steve doesnt know how to get the anti-lag working? i thought i re-called in past topic on anti-lag he added some useful info 2 the topic... ima try2 find the thread now??? ....ive been searchin for awhile as well and i'am really contemplating switchin ecu's because it seems that those who know about anti-lag on the powerfc dont want to share there *secrets* i guess...

 

Steve is here right now and doesn't know how to hook the antilag up.

 

The anti-lag will ONLY work IF you have a APEXi PFC Pro!! If you are using a regular PFC it WILL NOT WORK!

 

what proof do you have of this? why does the manual not state this? what does the fc pro offer than the normal powerfc doenst support as far as anti lag?

FC PRO

IGN CUT instead of FUEL CUT
0KM/h REV LAUNCH

Note: the REV LAUNCH is *NOT* the same as the datalogit anti lag

 

The only fd I know antilag to have worked on is the pfc pro
The rev launch feature is not too disimilar from antilag anyway.
It retards timing to build boost. Only thing it doesn't do is add fuel as well.

 

The regular PFC doesn't have the anti-lag built into it like the PFC PRO. Trust me I've asked APEXi about it, they've told me the same thing.

 

anyone know where to get a PFC Pro?

 

the PowerFC Pro clearly does not have antilag

it clearly has

REV LAUNCH
IGN CUT

 

what the hell is REV LAUNCH
IGN CUT?

 

I think the point he's making is that it has the capabilities for antilag to work with this ecu rather than the normal apexi.

 

Rev launch = when stationary with clutch depressed you rev the
car to a predetermined rev limit and when it reaches that limit it will
retard the ignition timing in order to produce a lot of heat which in turn creates boost. When normal driving is resumed and you hit your predetermined rev limit it will cut ignition instead of fuel.

 

I could use that, where can I get it?

 

I'll have a look tonight and post the url tomorrow.

 

the powerfc pro has two features over the normal apexi powerfc

1) REV LAUNCH
2) IGN CUT instead of FUEL CUT when you hit REVLIMITER

REV LAUNCH is not ANTI LAG (the one in datalogit)

 

anti lag retards ignition and dumps in a load of fuel. The rev launch feature on the apexi pro retards ignition but doesn't dump fuel.
I have the apexi pro on my daily driver.

 

as i expected, the powerfc pro functions have nothing whatsoever to do with antilag nor do they mean anything in relation to the datalogit antilag feature. the rev launch is purely to boot it off the drag strip start line at a fixed rpm for consistent launches and the IGN cut instead of FUEL cut is for when you are bouncing off the rev limiter with say 1000cc injectors and a big rev limit, rather than doing a fuel cut which could cause knocking/detonation do an IGN cut instead

To date the only rx7 I have seen with anti lag working is on the apexi pro.
i have seen others try and fail trying it on the normal apexi.
