Links G4 Anti-Lag wiring

Recommended Posts

Hey Lads, just looking for some help wiring my anti-lag through a switch, its a 1997 Evo 4, do I just choose a direct input into the ecu? do I cut the wire going into the ecu and run it through a switch going to ground, or am I completely wrong?

 

All help greatly appreciated

You need to wire the switch to an available Digital input.

People often use the AC input as its not often used in a race application.

The ECU can work with either a 12V switched in or a ground input.

The difference will be in the set up of the DI through PClink.

Thanks Simon, when I go into pc link I see that DI6 is free, will I just cut the wire going into the ecu for DI6 and wire it through a switch to ground, and let the man maping it do the rest?

Thanks

If you have our Evo 4 to 8 plug-in ECU then DI 6 is normally used for the A/C request signal. On the plug-in ECU we have a pull-down resistor on this Digital Input. What this means is that you can use it, but that the switch will need to provide a +V signal to the Digital Input. 

Remove the existing wire going into this pin, attach a wire to your switch. Then connect the other pin of your switch to an ignition switched power supply that contains a fuse.

In PCLink set the input up like this:

If you are not using air conditioning vehicle on your vehicle then DI 6 is a good one to use. Yes, allocate the DI channel as 'GP Input', in the Anti-Lag settings you then set DI6 as the 'Anti-Lag system Arming'.

Hi Scott, pull up resistor, should I have it to on or off?

 

Thanks

There are quite a few settings and some tables to setup. The help file has some good info on all the different settings, and also some setup examples, so make sure you have a read through of those.

PCLink Help > G4+ ECU Tuning Functions > Motorsport > Anti-Lag >

If you have any particular questions as you go through the setup process let us know.

thanks Scott, Am I right in saying I set up my cyclic idle first, I was going to set my idle to 20%, then set my lower cyclic to 21% and upper cyclic to 26%,

Also when I go and turn on the anti-lag in the anti-lag menu on pc-links there is no option for setting cyclic idle %

I was then going to set up my anti-lag as follows

·Anti-Lag System Arming = Always ON
·Cyclic Idle Mode = Always ON
·AL Enable RPM = 3000 RPM
·

AL Enable TP = 60%

in the help menu for the Anti-Lag Retard Table / Ign Retard Mode,     Anti-Lag Fuel Correction Table,    Anti-Lag Ignition Cut Tables there is example values (iv attatched) would I be safe to map it to these figures.

 

Is there a lot more to setting up anti-lag than this or am I way off, thanks

I'm doing my anti-lag the GrpN way using throttle plate to bleed air

when opening my throttle screw to achieve 20% opening where do I view this? is it the TP% gauge, I was just fooling around with it last night and when I moved the screw and looked at % the revs were very high and I was only at 8%

 

Thanks
