Is there more than 1 channel for fuel ? I think the later cars are fine with the fuel, it seems early Toyotas are an issue ?
I thought the issue with smoothing the fuel level would be in the ECU and the dash would just be displaying what its told?
So would I but it seems not… my oem fuel gauge was a little erratic when fuel was low, but on garw it’s quite erratic. Dave intimates that there is more than 1 channel, not sure why there would be 2… but I would like to understand as that may help to resolve a few of us with the dash where fuel readings are erratic as the tank empties…
Mine will go up 1/2 a notch from parking it on a slight gradient. I put it down to one of those things. Be nice for a fix mind!
2004 car , like yours …
So it seems the earlier cars only had one fuel channel - hence the jumping around reading with out loads of damping… later cars had an average and instantaneous… Wonder if the EMU black allows an average reading to be sent to the dash…
Well thats a juicy bit of info.
Pretty sure my white dash car had two channels.
I have also just checked the CAN protocol on the AIM software and the also list both instantaneous and average fuel level channels for the 2004-2007 cars
Well done. Lets hope its never needed…
Interesting Dave - Alec at Garw is convinced the earlier cars only have 1 channel… at least the T4 ECU (Manual throttle)
Car booked in for late July to have EMU Black fitted and tuned… will of course let you know results after that is done…
Nice, where are you booked in?
Hangar 111 - they did the 280s kit I have, so are probably best placed to get the best setup…
I have also emailed ECUMaster to see if they can give some pointers on helping me sort my fuel readings to the GARW dash
Good stuff, H111 are a bit far for me but looking to get into RRR Engineering for my install, looking like August at the earliest atm.
The guys at RRR Engineering were great when I got mine fitted 
Good news! Have you discussed T/C with them at all? I believe the EMU has a couple of options for it, one using the ABS speed sensors that came on all S2’s and one using an aftermarket speed sensor for some more gucci functionality.
I’ve not discussed Traction Control with them because it’s not on my radar… 
Lets not forget I’m driving the Naturally Aspirated version, haha 
I only need it if I’m driving like a plonker in the rain With smooth inputs mine is pretty planted.
I’m pretty sure the software shows it down the side bar and you can just turn it on with the parameters you choose. Again, I’ve not looked in too much depth because mine is far less likely to break loose than if I’d got some kind of forced induction…
Yeah fair enough, my current T/C is always disabled on track anyway otherwise it just kicks in every time the inside rear tries spinning up - can’t drive hard with it at all. I believe the EMU module for it has got options for variable slip though which might make it a bit more useful in wet conditions so it’s something I may look into, just as a bit of a safety net.
In which case… I may have a play when I get chance! I could definitely use a ‘safety net’ at Cadwell Park in the wet, lol!
You dont need T/C In a boosted car either TBH unless you drive with lead boots…
So my car is still at hangar 111, initial map done with an increase in torque and power, however they are not fully happy with it as it seems to be doing some strange things at the top of the Rev range. They are checking plugs, fuel pump and injectors, although plugs were done 2018 less than 10k miles ago, and fuel pump and injectors were upgraded as part of the 280s kit. It could be crappy fuel I guess, but that’s unlikely…
Waiting to hear what they find
