    Looks like I've found what I'm looking for

    Rev limiter

    Is it limiting at 6300, 6500 or 6700 when it's being harsh, and do you have a log so we can see what is happening? It could be that the settings are too aggressive and the "soft" settings at the start of the limit range are having more of an impact than planned, or it could be that the soft part of the settings are not aggressive enough and its getting past them and hitting the hard limiter that is intentionally harsh as it's there to save the engine and isnt really meant to be hit. Your config looks to be all defaults as far as RPM limits go so shouldn't be too bad but clearly arent quite right for your car.

    I have a DBW close loop idle issue

    It looks like that while CL idle is active, whenever you press the throttle to the point where you exceed the AP lockout threshold, it adds 0.4 to the CL idle trim immediately. I cant see where its getting this 0.4 from so it might be hardcoded, or it might be some multiple of your proportional gain or ethrottle base numbers. I assume the idea here is to have it gently return to idle RPM rather than try to "catch the stall" that happens with low ethrottle targets where the RPM can drop really quickly below where you want it. You can see that in the 8 times you blip the throttle, it adds 0.4% for each of the first 7, and between them when you're at 0% AP, the CL logic is actually doing its thing to reduce the CL % as soon as you get off the gas pedal (note at 32.2 sec that the CL number drops from 1.0 to 0.9 and status is DEC IDLE). On the 8th blip of the throttle something different happens though because the RPM is already so high from the current throttle angle, that you are above the RPM lockout for CL idle, and this time the CL% doesnt move at all. In the later part of your log it start off the RPM is too high for CL to kick in and reduce the CL% (so catch 22 here), but eventually overrun ignition trim kicks in and pulls 10 deg of timing (35-36sec) because you are under 0.5% AP and over 1500RPM, which drags the RPM down enough for CL to kick in and start removing the CL trim% until you get back to normal idle at CL 0.1-0.2%. I'm not sure if you set this up on purpose to catch this or its just a co-incidence that it does a pretty good job of fixing the catch 22 of too high an idle RPM for CL to fix itself. As far as how you fix this, you could try changing your open loop trims, proportional gain table, or ethrottle target table by a bit and see if you can influence that 0.4% number that is getting added. You could also try adding quite a bit the the proportional gain table to get it to drop CL% quicker once off the throttle. The link guys might have some info on the background logic at work here as to where this 0.4% comes from and why its being added every time you cross the AP throttle lockout number rather than just the first time like I would expect if its to ensure a smooth return to idle. You could work around it by just not blipping the throttle this many times this quickly so it has time to return to normal idle. I dont think increasing any of the CL lockout parameters will help much - increasing the lockout RPM you are just trading off how many times you can blip the throttle against how bad a high idle you have once you hit the problem. You might somewhat fix it by lowering the RPM lockout by quite a lot - it will still have the same CL % getting added but if the idle RPM exceeds lockout on the first or seconds throttle blips, its only going to be say 200RPM above target anyway and from this RPM you can probably tune your idle ignition control to pull back timing and get you back to where CL idle will work correctly. Its all a bit of a workaround though.

    Rev limiter

    My G4 extreme, the limiter is too harsh seems to cut fully. Could someone please have a look and suggest alterations to my setup. Normally asperated v8 5.0 in a light car. Thanks Mark ND Map.pclr

    Idle gets stuck higher sometimes

    Do you have the log file or just those screen shots? There are a couple of closed loop ethrottle offset issues that have been reported that last few months that sound similar. Can you post the whole log - the value we're looking for is ethrottle ISC CL trim % Are you on the latest firmware (released last week)? If you leave it for say 10 seconds does it slowly return to normal?

    [UPDATE] PCLink 5.6.6.3564 Released

    is that when the screen has gone off or does the tablet go to sleep? There's quite a few power management settings in Windows that could cause it to stop logging while the screen is off

    knocklink light g4

    Hi gain, I installed it next to oem knock sensor which is the prefect place for it. it work fine and it flash if the coolant temp is high toward the H side also it detect some knock which is good. but sometime it flash while im rolling at wot and if i do another test it does not flash again without changing anything.and that confusing me. what i usually do i do retard the timing a bit and i do another test and then i advance it to see if still knocking or that was just a flash. it happened from time to time but not alot maybe once every 2 days. The question is what might be the issue or what can cause that ? Also how can i knew if the flash was because of the sensor detect a knock ?

    You can use the Pinout Diagram along with the Installer IO Table (also in Help) to determine what can be wired up where. A safe strategy would be to fill in the Installer IO Table with your required sensors/outputs/etc so they are all certain to work. It was something I didnt do with my first build and I ended up chasing my tail a bit. Some things need to be on specific pins (ie. aux 5/6/7/8 for a stepper motor and DI 1-4 for flex sensors, etc)

    Low idle on cold startup

    Your warmup enrichment table looks pretty weak especially 20-50deg. Can you give us a log, make sure the wideband is warmed up/operating before starting.

    Unlock code help me

    Yesterday I just finished fitting my new link g4+ , Plugged my laptop in , got the ecu is locked ( as its brand new ) I went to the options , selected correct window , entered my supplied code. Comes up with a error . Says can complete fist action but not second????? Have i been given the wrong code?? or am i entering it wrong . or is there a bigger problem ? when i opened the box it had the wrong ecu ( a MX5 euc in a NGTR box ) which i returned and got another code. This is a JOKE . I shoudve got a haltech. How many times can i try to enter code before it locks me out???

    Low idle on cold startup

    Hi when I start my car it fires and starts but idle goes rather low then after say 20 odd seconds it comes up I have tried adjusting the idle speed for temp this does little .had a play with warm up fuel seems like it maybe rich and lean as it leans out the idle comes up or just thinking weather the closed loop is affecting it just checking now it's not on.nope it is set to 800 rpm but the coolant temp is 55 degress so should be good .do I need more warm up enrichment? cold start change.pcl

    Idle gets stuck higher sometimes

    This is pretty random but sometimes my idle will get stuck few hundred RPM higher than it should. The only way to correct it is to shut down and start again. It doesn't happen often but I've been noticing it lately. I was logging today when it happened so have some data, the throttle looks to be open more than what the actual pedal position would request. I'm not pressing the throttle here. (keep in mind this is a jetski so no wheel speed available)

    Thunder EGT question

    others have already used the ECUMaster EGT to CAN device for up to 8x EGT's And it's very cheap, seems to operate at around 5Hz which is fairly slow, but a thermocouple isnt super fast anyway so it's fine

    smart pencil coil options

    It's a motorbike application....not use some motorbike pencil coils ? And for those who have issue with coils being powered up but not running some will wire the +ve feed to the coils via the fuel pump trigger so they can never be energised unless the engine is turning. Although that shouldnt really be needed.

    Logging to tablet with screen off still is wrong, it freezes all the values at screen off instance but still adds them to the log timeline for the duration the screen is off

    Link extreme and Dash 2 connection issue

    Attach your tune file so I can check at least the link end.

    Link extreme and Dash 2 connection issue

    yes mate its one of their pre-programmed ones for the G4+ ECU'S. I have sent my Dash 2 config file off to RT to look at so will be good to know if that is correct or if there is any issues with how I have set it up. I will update the post as soon as i hear back from them!

    convert tune file from traditional to modelled

    The fuel map will need to be re-tuned. The overall shape won’t change drastically but the numbers will. As well you will turn off the IAT trim table and zero out rhe warmup enrichment.

    That is the sort of thing I would have expected in the manual for each unique ECU.

    I will try when I am in the company to put other schemes with the ecu vipec in evolution, opel 2.2 16v, evolution 2.3 and other cars. I hope this helps everyone. At the moment I only have Vectra with Autronic. Augusto. pdf_vectra_esquema_eletrico.pdf
