Hi, Which Xtreme do you have? Red/Silver? I have just tested the knock control on a silver model, seems fine. Do you want to send me your .pcl file and I will load that in and try again? [email protected] Another note regarding knock control, you will need to get a generic wideband bosch knock sensor. The Xtreme can't process the signal coming off a late model knock sensor. The only other option is purchasing a KnockBlock G4 as this is capable of analyzing this kind of sensor. Regarding the logging issue, I can reproduce this. My suggestion is working around it by triggering the logging off a virtual auxiliary channel. Maybe have it start recording when the RPM is over 10 so it creates a new log each time the engine is started? Closed loop boost control. Yes this is still in development. It's working well and its in its final stage of testing. Hopefully the next firmware release. Regards, Phil

Hi Edwin, Yes you need to delete a log file to create space again for a new log file. Regards, Phil

Hi, Possibly an issue, turn the analogue channel on. Set its fault conditions to 0v and 5v. Turn the channel back off. This should sort it. Regards, Phil

Hi Jeremy, The ECU unfortunately can not high side drive with a PWM signal. There is no setting for polarity as this is not really needed with GP PWM. If you want to invert the polarity of a 30% PWM signal you simply subtract 30% from 100% to get the percentage that gives the same waveform of opposite polarity. Regards, Phil

Ryan, You engine should start as well as it did with the factory ECU. Adjust your pre-crank prime and crank enrichment numbers, by the sounds of it the engine needs more fuel than its currently getting. 'I'm thinking the reason is because the Link couldn't put a ground on the power hold output fast enough when it detected a change in supply voltage.' - the ECU turns on the hold power output on as soon as the DI sees the ignition signal (the output is already on when the key is turned off). If you don't have a DI set to ignition switch, hold power won't work, this could be causing your troubles? Regards, Phil

The most cost effective solution is the Innovate LC1. Any wideband lambda sensor and controller with a 0-5V analogue output will integrate easily with the G4 ECU.

Hi Nick, Send it please, [email protected]. Thanks, Phil

Hi, As far as I know this ECU has not been tested on this engine. Do you have a pinout for it? If you do, compare it with the Link plugin ECUs pinout found in the back of the manual.

Hi, 'High level tacho' means that the tachometer requires a high voltage (aprox 400V) input from the coils negative terminal. Some companies offer the service of modifying the factory tachometer to a low level signal (12V). Your ideal involving the diodes does work. An after market tacho will work with the Link ECU if it states it is compatible with 12V tacho signals. Regards, Phil

Hi, Yes possibly a USB hardware failure, this can be fixed. Contact [email protected] for further information.

Hi Bazzasti, In the last G4 firmware release Version 7 to 10 trigger decoding has had a major overhaul. This should fix the problems that people may have. Regards, Phil

Hi Steve, Sorry about the delayed reply. I have added your request into our internal feature request system. One thing you may be able to do is share a GP limit table for two limiting parameters. For example Oil pressure on the X, Oil temp on the Y, the limit will be a combination of the two parameters. Hope this helps, Regards, Phil

Hi, What exactly are you trying to achieve? Currently you can apply a different calibration to each speed channel to compensate for different size wheels. Regards, Phil

Hi, Check that the fault settings are set to reasonable values, typically LOW=0.05 and HIGH=4.95. Also make sure you clear the fault codes, these will remain inside the ECU even after the error has been fixed until manually cleared. Let us know how you get on. Phil

Hi Mark, Example numbers depend on the application. Basically you want to run as little retard as you can to achieve the desired 'anti-lag' effect. Start with little retard and increase this as necessary. Your best bet would be to talk to a tuning shop with experience in setting up this type of rally car. Regards, Phil

Ok, in that case you can fix the problem using one external relay. Use a low side auxiliary output to drive a relay. Use this relay to switch power in parallel with the ignition switch to the main relays coil. Does this make sense?

Thanks, I will look into it.

Cool

Nick, Let me know how you get on. Cheers, Phil

Hi Mark, Your pretty much stuck with the buck in low gears. Does your class allow an ECU controlled air bleed valve? If so this would eliminate the need for cyclic idle all together. Cheers, Phil

Hi Petr. Yes, there will be no issues. All firmware developed for the new RX ECU will be applied to the Atom, Storm and Xtreme ECUs. Thanks

Peter, From looking at where you are on the map, we have Advan in Sydney and K-Tune in north Brisbane.

Hi Ryan, The most simple solution to your problem is to use Aux 5 - 8 with its drive mode set to high side. This will allow the ECU to switch 12V onto the relay. Regards, Phil

Hi Ryan, Do you have a silver or a red Xtreme? Thanks, Phil
