Removing aftermarket Controllers

So I was going to fit a better alarm to the car today until I looked under the dash. A maze or spliced wires, and hooked up relays. Just stripped wires wrapped around other stripped wires and insulation tape holding everything together.




There is a boost controller no make and I don't know what setting are on it cos I don't know how to use it.

Then there is a "Gizmo Fuel Cam" controller: From what I see you can control air/fuel and cam settings.
The previous owner said these were set up to run with the sard ECU. But I am guessing these are not very accurate settings. Not like a remap or anything so how good can they be? Would the SARD ecu on its own not be just as good?

I don't want any of them really, and would prefer to get the wiring loom nice and neat again not a maze of random spliced wires.

If i were to just remove them and do nothing else would the car run ok do ye think? Or would I be better off just leaving them in it and work around all the wiring.

We're these other gizmos adjusted to suit the map while it was on a dyno.
Or did the last owner just install them and put them at the settings that the install instructions say to.
If the latter I would say it's okay to remove them and clean up the loom.
I'm no tuner or qualified mechanic tho so this is only my thoughts on it.
Cant see them being setup on a dyno if they are just twist and tape installs lol
What boost are you going to be running?
The cars can be run on upto 1.3bar of boost without any afr mods.
What spec are you intending to keep and add to the car in the near future?

Put a couple of pics of the controllers up. I would not remove (unless there only monitoring) them if they alter anything without getting the car on a dyno straight after. I am no expert but I have seen how minor changes make a big difference to the map even air filters etc

His car only has an ecu with a sard daughter board with generic map hasnt it.
I could see it having an affect if it was all mapped in to the map.

Yeah just have a SARd daughterboard ecu, nothing specific to the car. Do people not run their cars with just these ecus? Or do we need the controllers with the daughter board ecus? I can't imagine you would pay for dyno time and not get a full remap, I don't plan on looking for much power. I am happy what it has by how it feels, But I don't know what the number has

Yes people do run with just those ecus.
Its always advisable to have them checked on a dyno to check afrs. ..
Alot of people used to run with just the boost turned up on a standard ecu.
Mine at the moment is like that.

Every car is different from the next so always best to have it checked on the dyno unless you have a wideband monitor.

I am lost off ? you said it has a maze of wires and a controller to adjust the air/fuel so that will be wired in ? That will be running along side the Sard Ecu to tweek the settings more so will of been adjusted on dyno so if you disconnect them the SARD Ecu unless the cars set up again won't be ok just to drive about in my opinion

Wouldn't removing the wired in afr gizmo just put it back to standard?
If it's like the hks afr it's inline on the afr wire so wouldnt affect the sard map because it wouldn't have been mapped into a generic map.
Thats how I understand it anyways.

Sounds like it's just a basic afr adjustment.

Wait a minute, so you've got some sort of daughter board and piggy back on a top of that?? If you're keen on doing stuff yourself I'd put afr gauge there just to make sure she's running right and then start removing stuff and see what happens, but don't listen to me just get it to somebody who could sort it for you. Or you can melt something....
