The ground wires on the ignition coils are like transmitter aerials. It is very important that they as short as possible and go to ground on the engine. If they are long and bundled with other wires going to the ECU, you will get interference.
Another thing I notice is you have the ignition coils signal grounds connect to the coil ground. The signal ground needs to be connected to the signal ground on the ECU.

Email me the map in the ECU. [email protected]

Please update your profile with ECU model and serial number.

I do not know of anyone every doing a direct injected Mazda 3. One of the dealers in Canada tried to setup s Volvo direct injection engine. The big problem was controlling the fuel pressure pump on the fuel rail. Driving the injectors was easy enough. After week of trying they got the engine to start and idle, but could not control the rail pressure as the throttle was opened. In the end they gave up. I do not know if the Mazda would be as hard to setup.

Make sure you have firmware that supports the latest revlimiter. If in doubt update to 4.7.1.
Use the settings below. Do not select ignition cut if the engine has a turbocharger. Very dangerous for the turbocharger and engine.
If you want it softer then this, then turn on advanced mode and set the control range to 400 rpm.

You can use any of the digital inputs as the switch input from your two step switch.

With the current firmware, full DBW Anti-lag is supported via the E-Throttle/Multiple table menu i.e you can switch DBW tables under different Anti-lag conditions ....You can use up to 3 tables.

The CAN will use information form various hardware that as CAN support. To do this we would have to add support as we just cannot make it so it supports everything out of the box. When it comes to adding data to dash streams this will be supported.

It should be set to the same Hz as the original ECU used. I do not know what that is, but looking at a map from one of these cars the customer was using 1000 Hz.

CAN will mean you can have 100 or more AIM dash's connected at the same time you have the PC connected.

Link are not going to be any help as their ECU do not have DBW, nor does a lot of other make ECU.
The reason the DBW is shutting down can be seen in the real time data. The error count for the DBW will go over ten and the ECU will shut down the throttle. The reason it is giving these errors is due to the throttle butterfly not following the foot throttle. The common causes are incorrect PID settings and the minimum and maximum clamp settings. The wrong PID settings can also make the Auto Calibrate not fully open or close the throttle butterfly. This means you start out with incorrect min and max range values.
I would set the PID settings as below and then recalibrate the throttle.
Proportional = 6.0
Integral = 0.039
Derivative = 25.0
Min Clamp = 80%
Max Clamp = -70%

April is still the date for the CAN an many other minor changes and fixes.
The Vipec already outputs the Motec data stream on the serial port. It will also do this on the CAN port, but not sure if it will be in the first release.

I have never had private messages setup on this forum.
I can be contacted on any of these.

No global warming is the cause of every problem around the world....

In the April version the limit will be raised to 10,000

There are no problems using VR sensors with 60-2 or any other trigger pattern.

Eric,
I have a map from a car with fixed throttle antilag, if you want to look at the settings. Email me [email protected]

Because of the earth quake in NZ the traction control will be in the July firmware release. The building collapsed in the earth quake and temporary premises are been used. This has caused weeks of lost time, plus necessary test equipment.
Sorry about this... Blame global warming...

The Vipec will have CAN support on the 1st of April. This does not mean anything using CAN can be interfaced. This is the reply by one of the Vipec engineers on your question.
Possibly, would need to know exactly what the factory ECU sends to the steering controller before I could say for sure. It will be very hard to work this out.

I'm using a grade magnetic sensor.
I do not know what sensor you are talking about. I would recommend you only use the original sensor.

The Vipec ECU have no problem reading 60-2 or more teeth at RPM higher then 9,000 rpm. Some other make ECU may have a problem, but not the Vipec.

The plan is, for this to be in the next software/firmware on the 1st April.

Electrical interference?
in ViPEC V Series

This is the wiring for the coils.
Signal ground or sensor ground, is GND OUT (pin A24 and B22 on the V88)
