evo_gerard Posted November 29, 2022 Report Share Posted November 29, 2022 good day everyone. I'm embarking on a upcoming project where I'm installing a G4X extreme ecu and a MXS Strada dash street edition (link model) in an Evo 7. I have a couple questions to ask as I'm trying to plan everything out in my mind/on paper before. 1. Can the dash take care of the battery/charge light? 2. Is there a procedure to create a fuel level input? 3. The car has ACD, can the dash show when the ACD modes switch? I'm trying to do this install as clean as possible. I know for questions 1 and 3 I could install LEDs (as a last resort) if there isn't a way for the dash to take care of it. Any advice is greatly appreciated.

I can't speak to the EVO 7 specifically but often the resistance of the bulb is an important part of the circuit and so you might need to wire up a resistor in place of the bulb and then setup the dash to just turn on a light based on battery voltage. 6 hours ago, evo_gerard said: Is there a procedure to create a fuel level input? If you have a search on the forum there are a few threads with examples of circuits to give a fuel reading including ones that slow down the response so you get a nice steady fuel reading without the effects of fuel slosh. 6 hours ago, evo_gerard said: The car has ACD, can the dash show when the ACD modes switch? Once again I don't know the EVO 7 well but I imagine there is something you can tap into which will tell the dash the state of things. @Adamw might be able to answer these questions better as he has more experience with EVOs than me.

evo_gerard Posted November 30, 2022 Author Report Share Posted November 30, 2022 Hi @Vaughan thank you for the reply and the advice. i'll wire a resistor between pin 9 and 19 on the C-01 connector as i wouldn't be removing the dash harness. On further review i may be out of inputs after i wire in both blinkers, hi beam, low beam, engine check light and the fuel level so i'll use 3 small LED bulbs instead. Thank you!

Check engine light can be sent from ecu to dash via CAN, no input needed. For the ACD mode lights I have never studied how those are triggered on the stock dash. They could be as simple as 3 separate on/off signals, or it could be something more complex like serial or K-Line. For the fuel level you will need to add a pull-up resistor, see page 3 of this doc: https://www.aim-sportline.com/download/faqs/eng/hardware/sensors/mx_series/FAQ_Sensors_MXx12_StradaSpieIcone_100_eng.pdf Quote Link to comment Share on other sites More sharing options...
evo_gerard Posted November 30, 2022 Author Report Share Posted November 30, 2022 Hi @Adamw thank you for the reply and advice. I was wondering if I could use pins 10, 14, 15 on the C-01 combination meter connector as the signals for the ACD status. Jumping ahead here, what could be used to "slow down" the fuel reading when the fuel in the tank moves around. Quote Link to comment Share on other sites More sharing options...

Yep, it looks simple, connect these to AIM inputs if you have enough spare, turn the pull-up on in the aim software. 10 hours ago, evo_gerard said: Jumping ahead here, what could be used to "slow down" the fuel reading when the fuel in the tank moves around. There is a filter setting in the dash software for that, nothing special needed for the wiring. Quote Link to comment Share on other sites More sharing options...
evo_gerard Posted December 1, 2022 Author Report Share Posted December 1, 2022 Thank you very much @Adamw. When I finally get the project started I'll report. I'm going to try to make custom icons for the 3 ACD modes. If I'm successful I'll post them here for anyone to use. Quote Link to comment Share on other sites More sharing options...
evo_gerard Posted May 31 Author Report Share Posted May 31 Hi guys, sorry to revive this tread but I did promise to report back with my findings. so for the battery light i used a 470 ohm .5 Watt resistor and it was successful. and i was able to wire the ACD modes to the analog channels of the dash. i setup 1 icon that changes colour when i change between the different mode. my next step is to tackle the fuel level. i'm following the document that @Adamw posted above but i have one question. since the evo have a main and a sub fuel gauge, do i measure the resistance of both and take an average or do i just measure at main sensor?

The sensors are wired in series with just a single wire going back to the dash. As far as I know both sensors are the same, so measure 1 and double it. evo_gerard 1 Quote Link to comment Share on other sites More sharing options...
