Ok. I looked in the knocklink installation instruction and there is no information about it. Â Is there any instruction? Can you give me a link to these instruction. Â Thanks.

Hi. Is it possible to connect a Knocklink G4 to a G4 ecu so we could issolate cells that cause a Knock?

My boost control setup is the one illustrated here. I am using the external wastegate setup. http://www.linkecu.com/support/documentation/technical-drawings/G32%20Boost%20Control%20Plumbing.pdf I was able to achieve a good control on the boost by using a restriction pill between port 2 and the top of the wastegate. Without pill, I was overboosting in higher gears. If I remove the hose between port 2 and the top of wastegate, I was not able to boost above wastegate pressure. My duty cycle are in the range of 10% to 35%. I did a 2D map with SPEED as the vertical axis. It is equivalent to a gear compensation but with better resolution. I will test it tonight. Close loop would be great but I would like to, at least, be able to control it a little in open loop.

Setup: 2.5L engine with 8.75 CR. VF29 turbo. 40mm external wastegate. 3 ports grimmspeed boost control solenoid. Â Problem: The tune was completed on a dyno (timing, fuel, boost control). Target boost 16psi at 4000rpm dropping to 10psi at 7000rpm. Once on the road, boost was reaching 20psi at 400rom and 14 psi at 7000rpm. Load seems to be a BIG factor in my issue. Â Tests: I did try to run wastegate pressure (0 duty cycle) and it is perfectly stable at 9psi. No leak anywhere in the system. Â What could I do? Thanks.

Hi Scott. Thanks for the anwser. And yes you are right I was looking on the top PCB. IÂ will have to order the expension connector. Â

Hi. I will install my newly purchased G4 on my impreza STI V6 soon. I would realy like to avoid using the expension connector. I have seen on the internet that I could probably use a pin on the standard ecu connector.... Depending on my PCB revision!? Could it be possible to know witch pin to use? I have a v1.2 PCB. I could probably find information on the web somewhere but so far my research have not be sucessfull. Thanks.
