This will depend on what outputs you have available. If possible you would be better to run the injectors sequentially (needing 6 injection outputs). Not having VVT should free up Aux Outputs 1 and 2, and Digital input 2. Scott

Glad it is now working. Scott

Ok good idea. Scott

Hi Tony, It looks like you have some conditions for logging to start, engine speed needs to be over 3000 rpm and TPS over 5%. Can you record a short PCLog of these conditions being met and then upload the log? Thanks, Scott

Hi Steve, Have a check of the VVT tab of the runtime values window and see what the status of each cam is and what the reported position for each cam is. We have a 1UZ-FE VVT engine as a dyno test engine and on that we have the pullup resistors switched off and the active edge to falling. If you do the VVT Cam angle test do you get any results showing on the VVT tab of the Runtime Values Window? Scott

Yes, if that speed sensor will physically fit to the transmission then the ECU will be able to work with the sensor output. You will need to play around with the calibration number until the speed reads correctly in the ECU. Scott

Looking at our WRX V1-2 plug-in ECU the speed signal should come in on Digital Input 4, which is pin 58. Look at the 'Digital' tab of the Runtime Values Window to see if you have any frequency or speed showing up on digital input 4. If you do not, then go to the Digital Input 4 settings and try turning the pullup resistor on. Check again to see if you have any data coming in on the Digital tab of the Runtime Values Window. You can open the Runtime Values Window by pressing 'r' or 'F12'. Scott

You can only open a G4 base-map in G4+ PCLink if you are online with a G4+ ECU. If you attempt this offline you will get the error you are describing. Scott

We do sell the GM 3 bar MAP sensor: http://dealers.linkecu.com/MAP3_2 Check that the MAP sensor is receiving +5v and ground from the ECU. Scott.

Hi Daniel, Do the following: 1. Save the G4 base-map to your hard drive from the G4 ECU. 2. Install the G4+ ECU. 3. Turn the key on, but do not start the engine. Connect to the G4+ ECU with PCLink V5.6.4 (our current release). 4. Load the base-map from the G4 ECU (on your hard drive) into the G4+ ECU. Store the base-map to the ECU (F4 key). 4. Update the firmware in the G4+ ECU by clicking ECU Controls > Update Firmware. Select the firmware 5.6.4. 5. After the firmware upgrade is finished go through all the settings and check them. The G4+ has a lot of new settings and these need to set to sensible values. Regards, Scott.

Looking at the Aim setup file you have selected the '500K' ECU stream. So you will want to set the Aim to the 'CAN Bus Base LCC' ECU stream instead. Looking at the ECU's CAN setup you have CAN module 1 set to 500 kbit/s, and CAN module 2 set to 1Mbit/s. Which one do you have the Aim wired to? Whichever one you have the aim wired to should be set to 1Mbit/s (to match how the dash will be setup), and the other CAN module should be turned off. Scott

Ok cool, it sounds like you have it working well. I'll forward your suggestions regarding e-throttle and launch control to the engineers. I'm pretty sure the e-throttle overlay one is already on the request list. Scott

Thanks for the post. Very interesting to see what can be done. When you run the traction control alone what value of slip are you targeting? Also, does the ECU achieve the targeted slip as expected? Scott

Hi John, Here is the oscilloscope images when setup as requested. I used direct spark ignition mode (as Adam suggested). The first image shows same channels as previously. In the second image the yellow waveform has been changed from Trig 1 (24-2) to Ignition output 2. I only have 4 channels, so this was required to show all the 5 waveforms. Scott

It looks like there are a few ways to make this work. In terms of simplicity telling the ECU that the engine is a single cylinder 2 stroke with direct spark ignition (wired to a wasted spark coil) would be good. This would allow you to adjust the injection timing from 0 to 360 degrees. The only concern would be can the injector drive supply sufficient current for the two injectors. Each injector drive can deliver up to 5.0 amps. What is the impedance (Ohms) on your injectors? No problem to split the ECUs ignition 1 output to multiple ignitors. Here is some screenshots from the ECU being set up like this. I used the trigger offset of 164 degrees still. The first image is with the injection timing set to 0 degrees.. The second image is with the injection timing set to 180 degrees. Scott

Is this log using the 'vt lowside fuel' base-map? Scott

Your injector deadtime seems to have changed significantly. Are the values in the 'vt lowside fuel' base-map the correct values? How many ohms of impedance are the moran injectors? Some of these are very low, and so require a lot of current. Although I'm not sure how a firmware upgrade would change anything with this. Scott

I think Adam's idea will work. I think you'll also have to tell the ECU that the engine has direct spark ignition. Ignition 2 will then be used for ignition, but you won't hook anything up to it, you'll just have the wasted spark coil connected to cylinder 1. Here is some oscilloscope images as requested. Both are the same as the last ones except at 1/2 engine cycle injection rate. The first one is with an actual pulsewidth of 2ms, an the other is with an actual pulsewidth of 10ms. Scott

Hi James, For a digital input channel the on/off threshold is at ~1.5v. Scott

Is this the same issue as here? Please upload your base-map also. Scott

The CAN-PCB cable will need to be plugged into the 'CAN/RS232' or 'CAN 2' socket on the bottom (bigger) board of the ECU. In the ECUs CAN Setup you need to select the CAN module you are wired to (CAN 1 or CAN 2). Nothing needs to be done on the streams tab. The CAN-PCB cable connector pinout matches the image shown in the Aim pdf file you linked to. Try the transmit frequency on 20 Hz or higher. Here is a document showing how to set this all up. If the communication still does not work please upload your ECUs base-map. Scott CAN - G4+ to Pista MXL.pdf

Hi David, Thanks for letting us know about the error. Hopefully they will fix it on their site and we can then screengrab the updated data and update the sticky. Just to confirm, it is the 12v 65.0 psid value right? Scott

Hi John, In the previous images I forgot to say I was on an Injection Rate of '1/2 Engine Cycle'. In the following image I am on '1 Engine Cycle'. I don't have a 24-3 trigger mode, the closest is 24-2, which is what I have used. Yellow is the 24-2 crank trigger (Trig 1)Light blue is the ignition pulse (0 degrees)Dark blue is injection drive 1.Pink is Injection drive 4.Trigger offset is 164 degreesInjection actual pulsewidth (including deadtime) is 2.011 ms Scott

Hi Adam, Yes, they can be used with the external e-throttle controller. We no longer manufacture the controller, but watch this space... Scott
