All of the G4 range can be set up to have closed loop lambda or quick tune. Only requirement is a wideband input to the ECU and for the function to be set up.

Hi  No sorry all sold out some time ago.

I suspect the trigger mode you will need to use is the EJ25 AVCS option. This is geared for the crank sensor in the pic and then 3 hall effect pulses of each cam.

Going from your map the set up is currently set to sync off the crank. If you have a single tooth cam sensor trigger 2 should be on cam x1 Do you get signals on both triggers in the runtime display?

The Conditional filters are for requirements steady state (not changing rapidly) that must be met. The Transient filters to allow for changing values. Some of the tuners out there might be willing to suggest some settings they use.

I'm assuming that the crank trigger is not factory? Given the 12 tooth setting. What are you running for a cam sync? In the file you have sent me it is set to crank x1 is this correct?

Thanks I have the map and will be back in touch soon.

To connect to the CAN/RS232 port you will need one of our CANPCB cables. From this we can supply a serial cable (9pin) or a flying lead that you can hard wire. Have done a bit of a look and see that racepak have an interface module for Vi-PEC this will also work with the link ecu. What I couldn't find was how the two connect.

Also make sure both triggers are configured as reluctor.

Hi Ahmad  Do you know how many teeth you have on your application as some BMWs ran a 58-60 tooth wheel on the crank. If you have 116 teeth this signal will have to go to trigger 1. The second signal should be a single tooth and this must go to trigger 2. Your trigger 2 setting should be 1x crank.

You will need a free aux output. This can then be configured as a GP output. This will then give the option of using up to 3 switching conditions. You could then switch the fans based on IAT, RPM as well as something else maybe boost.

You will need to wire the sensor to a DI. This DI will need to be configured as a speed input. The Calibration number allows the ECU to calculate ground speed in km/h. Note: In some cases erratic speed signals can occur due to unusual speed signal shapes. Changing from Rising Edge to Falling Edge or vice versa may help with this problem. This problem usually presents as random spikes of increased speed. Set-up Procedure: The Calibration number is the number of pulses received over a 100 m distance. Method 1: Drive the vehicle at a known speed and adjust the calibration number until the Vehicle Speed Runtime Value displays correct. Method 2: Wheel Speed Sensors Only. Calibration Number = (Number of Sensor Teeth / Wheel Diameter) * 31.83. Note that wheel diameter is in meters (m). Typical values for speed calibration numbers range from about 170 to 280. Â Note: Vehicle Speed can be checked in the Runtime Values Digital Inputs tab.

Hi Dima Can you email me the map [email protected] Also check that the firmware on the two ECUs is exactly the same.

Will be best to check the polarity on a scope. We want to see the signal rise first and then fall sharply through zero before going negative.

The biggest concern is the 3600 cal number. This is too high. The frequency is too much for the DI input. Suspect you will have a 40 tooth wheel and will need to find a 17 tooth. Another option is to fit a frequency reducer that I think Ray can offer. To allow the ratios to be entered higher than 2.69 you will need to go in to the ECU calculated mode and turn off the Normalise Ratio Table. Then you can go back to user defined and enter values.

Try doing a restore to factory settings. Then reload the map from the working ECU.

You will still have the MAP as you can remove the ECU and store it for years with out any loss on memory. The missing 12V to the coils will pose a problem. This might be on the same feed as the fuel pump so might only be there whilst the pump is running. You can also get in touch with either of the following Arizona Off Road Buggy Supply (O.R.B.S.) 2525 E. 16th St. Yuma, AZ 85365 Tel: 928.783.6265 Vivid Racing 1835 East 6th St. Suite 26 Tempe, AZ 85281 Tel: 480.966.3040

You could connect it to an aux output. You can then configure it to switch under your chosen conditions if you need more than 3 then you can also add in a virtual aux to give you more.

You could set the fan to be controled off a GP out put. Then use a virtual aux as one of the conditions for the GP. This will give all manner of configurations to switch off.

Plug in will be the go. No point doing a wirein unless you want a striped out loom or extra inputs or outputs the Xtreme could offer.

Main things you will need to set up will be the injector dead times. Injector dynamics are good at supplying these with the injectors. Make sure you do a TPS and MAP cal. Configure all IO. We don't have a full base map. However there might be someone out there willing to share.

2.69 would be far closer to what I would expect to see. Also would have expected the ratios to stay the same. Do you by chance know the number of teeth the speed sensor is seeing as 3600 is a very large number for the cal.

I can confirm you are correct. We will have to investigate further to find the course. Currently the maximum ratio is 2.96 What is the application as a gear ratio of 9 is super low gearing.

Have got the file Ill now try to recreate this on the bench.

Have just tried this on 4.8.1 VTS and firmware and it works on the bench. What Firmware and VTS are you running. A copy of your map could be handy as I can then get the setup exactly the same.
