Hi Lee, It sounds like you definitely have a back feeding issue. I take it that it all used to work fine? It could be a faulty ECU. If you are interested in having it checked email [email protected] Cheers, Scott.

Good morning, The GTS/GTR Plug-in ECU can have a knockblock connected to it for knock control. It requires a spare digital input (available at the expansion connector) and a spare auxiliary output. Unfortunately the GTS/GTR ECU has no spare auxiliary outputs, so you would have to sacrifice something else to make it work. Perhaps the check engine light or A/C output. In the Support > Documentation section of our website you can find the manual for the GTS/GTR ECU and the KnockBlock. The G4 Xtreme can do anything that the GTS/GTR plug-in can do. It would also allow you to have direct spark ignition and a lot more inputs and outputs. The Xtreme also has inbuilt knock control, although it is not as powerful as the KnockBlock. In terms of wiring an Xtreme in you would have to connect the Xtreme wiring loom into the loom that supplies your current ECU. We are not aware of any problems with using our ECUs on a GTR. Installation and setup of the Xtreme would be a lot more work than the GTS/GTR plug-in ECU. The tuning could be more difficult because of the individual throttle plates. It would be worth speaking to a local tuner to see what their experience on these is. Scott

Hi Carl, Because the G1 is now so old we no longer do any updates for it. If you wish to gain the additional features the only solution really is to upgrade your ECU to the current generation. By tuning your AFR's some you may be able to gain better fuel consumption. Be careful not to go too lean though. Scott.

Hi Lee, Pin 9 on your ECU is an aux output, it will have 12v + present when it is not switched.  I believe pin 46 should be the input into the ECU for your A/C, are you getting a signal on this pin? Neither of these pins should have any effect on your ignition system, if you break the connection to pin 9 does it stop your ignition problem? With your idle issue, it sounds like your idle base position may be too high. You should have an 'idle hot' and an 'idle cold' setting, try lowering these. Scott.

Hi Carl, In response to your questions. 1) Which Link G1 do you have? The features they had varied a fair bit. I'm not aware of any supporting closed loop idle control. 2) You could use the simulated narrowband setting and feed this into your G1. This should give you a more accurate signal. 3) The knock control should retard your ignition timing when knock above your threshold is detected. Cheers, Scott

Good morning, It is hard to say without seeing a log or the car, but normally having a lean AFR is caused by one of two things: 1) There is not enough fuel, if the AFR progressively gets leaner then this possibly could be the problem. However you mentioned your injector duty cycle is only at 70% and I'm assuming you've tried increasing the cell values in the fuel table. 2) You are having an ignition misfire. Possibly an ignition component is breaking down. If you can send me your basemap then I can test it on a simulator and try and identify if the problem is a setup one. You can either reply to this post and attach your basemap or email it to [email protected] Scott.

Hey again, I think if you can borrow a wideband O2 sensor and then check what your Air/Fuel Ratio is like it will give a good indication of what is causing the problem. If you can not find what is causing the problem, record a PC Log (including wideband) and send it to us for a look along with your basemap. We may be able to see what your problem is. Cheers, Scott.

Hi, Can you explain what is happening in more detail? Where in the world are you located? We may have a local dealer that can help you. Scott.

Hi Ryan, You can use the Wideband 0 to 5 volt output with your G3 Linkplus. It will be connected to any spare AN Volt channel. You will then need to configure the AN Volt channel for the wideband sensor, the voltages at certain AFRs will need to be known in order to do this. With the G3 there are three uses for a wideband signal 1) PC logging. You can log the wideband data along with other parameters to help identify problems 2) As an aid when tuning the engine (although I think your kit comes with a gauge) 3) Closed loop lambda fuel control. On the G3 Linkplus you are unable to use the wideband as a safety device as GP Limit tables were not introduced until G4. Your ECU is capale of being upgraded to G4, if you are interested email [email protected] Cheers, Scott.

Hi Nicky, Turn around time would be about three days once it arrives. For pricing information please email [email protected] Cheers, Scott

Hi Nick, The factory triggering is known to be pretty good. One of the guys here has a modified 3SGTE and is using the factory triggering with no problems. He said he uses the 24 tooth signal. A trigger wheel on the crank would also work fine if you do decide to go that way. Cheers, Scott.

Hi Andrew, Have a read over this thread http://www.linkecu.com/forums/G4Forum/382067331 It contains information on using log data outside PCLink. Regards, Scott.

Hi Rob, Which version of Firmware are you running in your ECU? There was an issue with this in an older firmware version. I have done some testing on the latest firmware version and using a calibration number of 250 it seems to work well. Scott.

Hi Guys, The job is a big one, several thousand hours will be required. The memory on the current ECUs mean there just is not enough room to add more tables. The only way to increase the amount of tables would be to remove other features from the ECU. Scott.

Hi Nicky, Good to hear you've had the car tuned. The output from the ECU to the boost solenoid would need to be tested to identify where the problem lies. The output is a frequency signal and would need to be checked with a scope. If there is no signal then possibly the ECU has a fault. If there is a signal then the problem would lie in the tuning or a problem after the ECU output. Scott.

Hi again, If you can reply and attach your basemap I will have a look at it and see if I can identify what the problem is. Scott.

Hi Logan, I do not have a basemap for a supercharged 1UZ-FE, but do for a relatively standard VVTi engine. The basemap is included in the PCLink install. Scott.

Hi Mike, While the knock block and the G4 Xtreme are both capable of detecting knock they are not duplicate items. The vast majority of tuners installing and tuning Link ECUs will own and use a knock-block to setup the knock on an ECU. The knock-block is more advanced than the knock detection circuitry in the G4 Xtreme and also has the audible output. Most tuners will sit there tuning with the audio output feeding into some headphones. The G4 Xtreme is not capable of producing an audio output. For an individual installing and tuning just one ECU I can see how it must seem like a pricey add-on. Have a read through the user manual for the knock-block (http://www.linkecu.com/support/documentation/knockblock-g4-documentation). It contains some information on different methods of setting up knock control. Cheers, Scott.

Hi Shamil, We have not had anyone run the 2JZ plug-in ECU with the VVTi engine. It may be possible, but I think it is unlikely. Apparently the VVTi version of the 2JZ has a different connector at the ECU. The other problem is that the Supra plug-in does not have any spare auxiliary outputs to run the VVT solenoid. Scott.

Hi, It is hard to tell what is wrong without more information. When you say the engine stalls for 4 seconds, do you mean the engine stalls and then can-not be started for 4 seconds. Or do you mean the engine misfires for 4 seconds? Scott.

Hi Mike, PCLink comes with a range of Subaru basemaps. Whichever one you use will likely have to be modified to suit your install. The Subaru v10 basemap is from a 2007 WRX EJ25 with AVCS, so could be a good starting point for you. The knock link is useful, but its primary function is more as a warning rather than a tuning tool. The Knock Block would be a better tool for the job. To be honest I am not sure about the tablet, I can't see any reason why it would not work. I have always used a laptop for running PCLink and have not had any feedback on tablets. There is a thread on here about running PCLink on tablets, although it mainly deals with android systems. Here is the link http://www.linkecu.com/forums/G4Forum/632110636 http://www.linkecu.com/forums/G4Forum/632110636'> I would be interested in hearing how using a tablet goes. Regards, Scott

Good morning, It depends on which plug-in ECU you are using. If the vehicle the plug-in was designed for has variable cam timing then the plug-in ECU will be able to control it. Scott.

Hi Yasir, The Link ECU does not control the airbags, this will have a separate ECU that needs to have its faults reset. Most vehicles need this done with a scan tool on the OBDII port. Possibly you could try disconnecting your battery for 20 minutes and see if this clears the airbag light. Regards, Scott.

Good morning, In PCLink go to Limits > RPM Limit > RPM Limit. Set RPM Limit mode to 'Fuel % cut' or 'Ign  % cut' Then select the RPM Limit table and fill it in to the RPM you wish to limit your engine to. Cheers, Scott.

Good morning, Connect your shift light to one of your spare auxiliary outputs. Connect to your ECU with PCLink. Set Aux 1 (or whichever number you are using) to GP output. Set Switch logic to 'condition 1 only'. Set SW Cond 1 to 'RPM >'. Set Engine speed to whatever RPM you want the shift light to activate at. Scott.
