Hi Mate,
I need a couple more 0-5 volt inputs for Fuel and Oil pressure, also a couple of PWM outputs to be configured i tunerstudio for both fuel and thermo fan speed control, would this be possible?
Not on this version, you would have to look at the pro version for that.
Ok Cool.. would it need to be the STM32f407 version?
can this work on a v6 wasted spark ?
yes, has 4 injector and ignition channels, would be able to run upto a V8 with paired injectors and wasted spark configuration.
on the diagram pin 25 am seeing sensor ground and a arrow pointing to battery negative , question is it just sensor ground on is it suppose to be ground for the ecu too?
All grounds (negative battery) need to be grounded at the same place, 25 is main ground and can be used as the sensor ground. Make sure you use heavier gauge wire for both the grounds.
Have spare imput via CAN hi and low??
No, Speeduino firmware doesn’t support CAN and this is a budget ECU, The STM32 Version does have CAN, But currently unavailable due to testing and Covid-19 parts deliveries.
Regards: I have your ecu mega 3.5 pro model on toyota corolla with 3.0 v6 toyota sienna engine ready installed runing the car about 6 month. Today im conected witha the laptop to verify and i think that tha firmware is corrupted because initial settings is in basic but when i select advance engine shutdown, the tps is always 100% inclusive if i disconect that , and dont permit calibrate, when i press the accelerator pedal both gages clt and iat swipe between 80 to 136 degrees.if i cranking the engine not register rpm and always is in floodclear. I need the firmware to reset the ecu.
Did you download the INI file in the instructions and use it in Tunerstudio? and is it the same laptop you set it up on? Sounds like the wrong board is selected.
Greetings I bought 2 3.5 basic mega ecu and I need the diagram how can I get it
I will email you the diagrams
Hi,
Is there a part number for the pin outs on micro ecu. A few crimps failed and now in short supply. Any stores that would stock them would be perfect?
Sorry for not responding sooner, seems there was a problem with the page not letting me know there where questions. You may have got this sorted by now, very sorry.
