Wouldn't surprise me if it used to be engine speed / speed frequency but was changed at some point without the help being updated. G4X is definitely RPM / Wheel Speed. I've corrected the G4+ help on my end but you obviously won't see that updated until the next release.

Has been fixed, thanks

Those both look like they're off a VQ, the info for them is in the wiring section of the help manual.

Which plugin are you using and where are you connecting to on the plugin? How are you wiring up the relay and bulb?

No difference in trigger offsets between any of the G4X ECUs, the offset is software based and they all run the same software.

Yup, we tried to make the offsets closer to 0 for vehicle specific modes in G4X

Have you checked your ignition timing? I would expect your trigger offset to be near 0 on a G4X.

Link ECUs have a stop input (like a DI) which can be used from PCLink with a little trickery. In G4X go to Digital Inputs -> Stop Switch and set to Always On. In G4+ the easiest method I can think of is to set a spare Digital Input to stop switch and change the On Level to activate/deactivate it. The Stop Switch input applies a 100% fuel and ignition cut when active.

have you set this? What does it look like under the Runtime Values ECU Status tab? Note that it won't show Lambda values until a short time after the engine has started.

The knock retard is visible in the Cylx Knk I-Trim runtimes, the reason it doesn't show up in the main ignition angle value is that the retard numbers are typically cylinder based rather than overall.

the Auxiliary controlling the ethrottle relay will show active when it has the relay turned on and inactive when it is off. There is also an Aux 9/10 Supply runtime that shows the voltage of the E-Throttle power input. There is not.

The multifuel setup is intended for a system with the ethanol and petrol mixed together in the tank and the split being controlled by an ethanol sensor which detects what percentage of the fuel supplied to the engine is ethanol. A system where you have dedicated injectors for ethanol and dedicated injectors for petrol is theoretically possible but you would have to set it up in the ECU as a staged fuel system and feed that staged percentage into the multifuel setup as your ethanol percentage. For a system with 16 injectors you could set it up as group staged where each odd numbered injector drive is connected to two primary (petrol) injectors and each even numbered injector drive is connected to two (secondary) ethanol injectors. The current G4X range only supports High Impedance injectors but it is often possible to run low impedance injectors with the use of a ballast resistor, this would depend on the specific injectors you are using though as I imagine you are wanting to use low impedance injectors for a more specific reason than them being a factory item.

change your E-Throttle fault delay to 0.1s

can you attach a copy of your basemap please and a short log showing you trying to make it move.

The ECU compares the target to the position and shuts off the E-Throttle if the actual position doesn't track the target position properly. In other words the E-Throttle setup in the ECU already does what you are asking for so there is no need to use an external system for this. You can transmit the target and tps over CAN if you so wish. If you wanted to cut the E-Throttle power supply from your own device you could set your E-Throttle Relay output to an output that isn't connected to anything and then use a GP Output to control your actual relay based on the E-Throttle Relay output (the one not connected to anything) status and the CAN input. This would not be generally be recommended though for safety reasons. Alternatively you could have two relays in series on the ECU Power and control one from the E-Throttle Relay output and the other based on the CAN signal via a GP Output.

I assume that is a GTR plugin, it looks like the Idle speed flyback diode

yes, your closed value will just be larger than your open value.

When controlling the E-Throttle motor directly from the ECU the signal out is just a ground on one wire and power on the other with which is ground and which is positive being swapped at a high frequency. When the controller wants to move the throttle plate in a certain direction it spends more time with the motor powered one way than the other and so the motor moves in that direction. How long the motor is powered in each direction is described by the E-Throttle Motor Duty Cycle, this duty cycle is positive when the motor is powered in the open throttle plate direction for a greater period of time than in the closed direction on average and is negative when the motor is powered in the negative direction for a greater period of time than the open direction on average. This setup differs from standard PWM in that the two wires are synchronised together so when one is high the other is always low and the onboard ethrottle controller has special hardware to actually pull the 'high' pin high to provide enough power to move the E-Throttle motor. TLDR: The E-Throttle motor is just a DC motor that is being powered in each direction alternately and the longer it is powered in one direction the more it will move in that direction.

If you want it to switch at a specific voltage you can wire it up to an analog input and setup a virtual aux based on that analog value.

Is there anything specific you would like to be presented clearer on the EVO4-8 stuff? I can make changes to make it easier for the next person. Thanks

you can use an analog as a switched DI input but the analog inputs don't have the hardware to read frequencies and Duty Cycles (The ethanol and temp data are transmitted as a pwm signal). Neutral switch can be used for idle trims but I wouldn't consider it to be super necessary so it would be a good option.

Looks like Daihatsu, dodge and a few others are also missing from that list, will flesh that list out a little. Is there anything else needed to run a Dodge Neon SRT-4?

Just had a quick check and it looks like the PT Cruiser 2.4 pattern is the same as that image

The sample maps were vaguely converted over from the G4+ ones but seeing as the PID setups changed between the ECUs I didn't have any solid new values to put in, if you get it all tuned nicely and don't mind sharing your PID values I can update the values in the sample map.

you've selected transmit user stream 1 but not setup anything in stream 1. Usually (depending on the dash) you would select Transmit Generic Dash or one of the other built in dash transmit options. What Dash do you have? I read your title, @Adamw might correct me on this but I believe you want to select "Transmit AIM MXS Strada Dash"
