Yep you could use a dash mounted switch to control launch.

You will need to check where the fuelpump control is wired in to the ECU. As I suspect its not on the AUX out you are expecting. Or there is a wiring issue somewhere else in the loom.

Have a chat to the boys at Shred or STM both in Wellington

It will give some good bangs as its going to be cutting ignition so you will have un-burnt fuel to ignite in the exhaust. Once the Di is deactivated (switch released) it will revert to normal RPM limits

A local dealer will be able to advise pricing. http://www.linkecu.com/dealers

You could configure the GP limit tables do this. AFR would be a nice solution only risk would be if the sensor fails.Â

You will need a correct Vnet unit to suit the G4. If using the serial interface what is displayed will depend on the dash configuration. For CAN it will the info in our generic dash file.

On the G4 you can almost use any sensor as it can have custom calibrations configured to suit.

No you will not need to as the factory one will be fine to use and is wired to temp 2 input of the ECU.

If you are driving off an Aux you might need to fit a external pull up to 12V if the drive is only connected to the Eboost and no tacho in the dash. A 1k pull up between the aux and 12V could work.

Just the wideband will be plenty no need for a narrow band input if you have a wideband one.

For cost you will need to talk to a dealer. The OBD is outputted on the CAN wires that come out of the CAN/RS232 connector on the ECU. These would need to be wired to allow connection of various OBD devices.

You could start off with the plugin map and lower the master fuel also check the ignition configuration suits for the V44. Will at least get the engine running this way.

My thoughts would be to retain the ams as you know this works well. The i88 can be added to do the fuel / ignition control and logging, you can then at a later stage change the boost control over if you wish.

Hi Koo You can use the transbrake to activate a digital input. This input can then be used to activate the Launch limit. You screen shot is in the correct mode to do this. It would be assuming you have the transbrake switch wired to Di1 it would need to be active for 2 seconds before the limit is engaged. I would suggest starting with the advanced limit mode turned off.

To an extent yes. It is just not possible to continue to add features for ever. We have pushed the V series Micro to the maximum that was able to be achieved. There will always be a time in a products life that development stops and the next generation is introduced.

Hi all. We have update available for the VX series. Nothing big but a tidy up. Please read the release notes VTS Help > Vi-PEC Tuning Software VX Users Manual > Release Notes> http://www.vi-pec.com/software/vts-v4-9-9.1784#

You can test the digital input buy configuring as a GP input and then manually switch the signal to ground.

There will be no new features added to the V series firmware.

A mazda GTX/R 1800 distributor would be a good example.

The sub-board will need to be either swapped or re programmed

You will need to go to the ECU Settings (same area you set up the I/O) then to ECU logging menu (down the bottom) From there you can set it being active based on a DI

It can be upgraded to allow PC tuning. This would be the main advantage.

The AN volt errors are likely to be from a sensor having been unplugged at some point. AN volt 3 is the TPS signal. The Hardware block error is more of a concern. You can try cycling the power to the ECU to see if this clears. If not it is likely we will have to get the unit back for inspection / repair.

You should just be able to T off you tacho drive. If you have no tacho fitted you might need a pullup resistor between the signal and 12 or 5 volts.
