With the flexfuel sensor fitted and the firmware that is coming, you will be able to tune on any amount of ethanol from 85 % to 0% and the tune will be correct at all times. You will not have to tune on E85 and then on straight petrol.

USB drivers 6.1 are not buggy. The problem with USB drivers is getting them to install correctly, not the actual driver. Laptops are the worst for installing drivers. If the current driver is installed and working then say no to installing a later version when installing new software.
Make sure the ECU has a latest firmware. 4.7.1

Anders,
Neel from Apex Speed Technology has been helping Miguel get the engine running. I guess he will post here when done.

If you have a non driven wheel for the vehicle speed, then you could use three or four Auxiliary outputs setup as GP Outputs based on speed. This would give you three to four speeds to shift gears on. They could turn on four LED one at a time when you needed to change gears.
As far as the GPS I cannot see how this would work, unless the GPS outputs a PWM signal that could be connected to a Digital input. I would think a non driven wheel sensor would be more accurate.

The VS can be connected directly to a Digital input. Either wire can be used, the other goes to sensor ground on the ECU.

Looking at the video it looks like he is shifting gears, everytime the shift light comes on. You can do this with the Vipec.
Connect a shift light to a auxiliary output. Select the auxiliary output as a GP Output with one condition. Make the condition RPM > 7000 for the shift light to come on at 7000 rpm.

If wheel spin is the problem, I do not see how flat shift is going to help. If the engine is turbocharged, then using a different boost in each gear works well. I use this on my car. In first gear I run the wastegate spring pressure (0.8 bar), then in second gear 1.2 bar and third and higher gears 1.5 bar.

Tim,

There are many things wrong with the map.
Before I list the problems, I want to comment on the mapping method selected. You are mapping the engine just using TPS. This is a very bad way to map an engine. The tune will never be correct at all rpm and engine loads. A carburetor would do a better job of controlling the correct air fuel ratio. The engine should be mapped this way...
Fuel Equation Load=MAP
Open Loop AFR = On
Fuel table Y axis = TPS
Ignition table Y axis = MAP
4D table = Off
Map sensor is then connected to all throttle bodies.
Problems with the map.
1. Update the firmware to version 4.7.1
2. Ignition delay has not been set.
3. Trigger 1 level is set to Level 2. This must be Level 1.
4. Trigger 1 thresholds are not as in the help file.
5. Trigger 2 Sync mode is set to Crank Pulse 1x. This must be Cam Pulse 1x
Another thing that bothers me is you have Bosch 846 injectors selected. If you are not using E85 or methanol, these injectors will not control very well on your size engine. If you need an injector that big, use the Injector Dynamics 1000cc or 2000cc. These will work perfectly on normal petrol.

Jason,
More then likley you or Scott installed the newer USB driver when installing 4.7.1 and this is causing the problem. I allways say "If it is not broken, do not fix it" when it comes to USB drivers. I am still using USB version 4.4 (current driver is 6.2) as it works with XP without problems.
As Scott can be hands on finding and fixing the problem, best to get him to have another look, and to contact me if he cannot find what is wrong.
-
Yes it works very well. You just need to spend the time setting it up. After that you get exactly the boost you want every time.

Many BMW crank and cam sensors have three wires. The wires are...
+ve
-ve
Sheild ground
If there is no voltage supply to the sensor, then they are reluctor.
In the software help there are all the trigger settings for the BMW 116 tooth trigger.
Look at Help -> Contents -> Engine Specific Information -> BMW -> M3
If you still have problems email me your map [email protected]

pin1 - +12 switched
pin2 - Vipec pin A24 or chassis ground on the car body.
pin3 - Ign Output 1-6
pin4 - ground on engine block or head.
If anyone needs wiring information on the 036-905-715F COP I have just fitted them to my 2JZ-GTE http://www.turbofast.com.au/lexusignition.html

CAN is not far away. We will look into just what is involved and when we can do something.

Yes..the flooding is bad. The water rushing though Toowoomba and washing cars away was amazing. No problems were I am. We are now getting "normal" weather like back in the 1970's. For many years it has been very dry, which is not normal...

Andrew,
You may as well use a bucket to pour fuel into the engine. That's how accurate TPS only mapping is. In fact a carburetor will do a better job of getting the AFR's correct under all load conditions.
The TPS and Manifold pressure mapping mentioned above is very good for multi throttle body engines. On turbocharged multi throttle body engines it is very important you use this method.
Add a vacuum line from each throttle body to a common point, then connect to a map sensor. If there is no vacuum ports, remove the intake manifold and add them.

This is the best I can do, as we have no PC with Linux to compile them on.
The Id's required to recognize a Vipec ECU are VID 12B8 and PID EC62. It looks like you have to add these entries to cp210xuniversal.h and compile the files.

With one throttle butterfly per cylinder, you would map the engine using the throttle position and manifold pressure method. The settings are,
Fuel Equation Load=MAP
Open Loop AFR table = On
Fuel table Y Axis = TPS
Ignition table Y Axis = MAP
This method of mapping is very powerful and makes tuning multi butterfly engines easy.
An adaptor can be made using the connector from the original ECU and the V44 harness.

You need to take the car to Wayne and get him to look at the settings and for other problems.

Yes many of us use PC with Win7. Both 32 and 64 bit versions work. You can get some USB driver install issues with the 64 bit version.

I cannot do anything until the 10th of Jan. Then I can find out what we can do for you.

The USB chip in the Vipec is made by Silicon Labs http://www.silabs.com/Pages/default.aspx
If there is a Linux driver available, it would need to be modified by us so it would talk to the Vipec. This is possible.

The point where the engine actually knocks could be any value from 0 to 1023. The knock level (noise at the specified frequency) will increase as you get closer to actual knock. The point where the engine is knocking must be found using headphones.
The knock amplifier targets the noise at the specified frequency. If it has noise at this frequency it outputs a knock level value. This value does not mean the engine is knocking, just that there is some noise at that frequency and the tuner has to decide if it is knock.
The digital knock amp is very good at targeting the actual knock, but only you with headphones can confirm you have actual knock.

With the USB cable plugged into the PC and the ECU, do you have the "VIPEC ECU USB (Com xx)" shown in the Windows device manager.
If you do not, then the USB driver did not install correctly.
If it is there, then what exactly happens when you try to go online.
