DanSJ80 Posted August 8 Report Share Posted August 8 Hi, I have got the motor running for about a week now, but i can't seem to get rid of a bunch of fault codes, I have checked my sensor earths, the voltage at the sensors receives 5V. I have wriggled the loom everywhere I can but nothing seems to change the running values when I do. i cant seem to fix MAP fault value either, doesn't matter what i type in it stays, i assume that has something to do with voltage error. very excited tho, the motor starts, idles and rev's better than it ever did on the factory ECU and i haven't even started tuning it. I also don't seem to know what i'm doing with the knock sensor, not sure why its not showing any values, yet when I go to knock audio its picking up noises. I think the trigger's are working fine as well. Trigger Scope - 2024-08-8 4;03;24 pm.llgx PC Datalog - 2024-08-8 4;02;51 pm.llgx Quote Link to comment Share on other sites More sharing options...
K4Tuning Posted August 8 Report Share Posted August 8 Hey you can try changing your error voltages. A lot of factory error voltages are .05V and 4.95V. Sometimes keeping these values will pop up those error messages. Try changing the error low and error high voltages to 0v and 5v. This should keep some of those faults off. Your knock sensor setup is a little more in depth but still pretty simple. The help section is probably the best place to start with that, Hope some of that helps. Let us know how it goes.

Have you cleared the fault codes? they won't disappear until you have and then you only need to worry about which ones come back DanSJ80 1 Quote Link to comment Share on other sites More sharing options...

I tried this, still same, thanks for the response 11 minutes ago, Vaughan said: Have you cleared the fault codes? they won't disappear until you have and then you only need to worry about which ones come back Yes, i've cleared them while engine is off and running, all seems to come back immediately Quote Link to comment Share on other sites More sharing options...

I hope i've done the pc datalog right. the AC thermistor isn't yet connected. g16b rev0.pclx PC Datalog - 2024-08-9 8;52;37 am.llgx Quote Link to comment Share on other sites More sharing options...
Vaughan Posted August 8 Report Share Posted August 8 How are you clearing the fault codes? that log shows 18 fault codes the whole log and I want to see them cleared part way through. ECU Controls -> Clear ECU Fault Codes while connected to the ECU is the way I would normally clear codes. DanSJ80 1 Quote Link to comment Share on other sites More sharing options...

I think the trigger's are working fine as well. The knock audio tool is for frequency analysis, it requires a knock amplifier (like the Link KnockBlock) to be connected to the laptop sound card to work. Knock control is generally set up and validated as effective after you have a reasonably good tune in it, but in any case, some basic knock settings that are wrong in your attached map: Disable Input is set to Always ON, this means knock control is always disabled. Freq channel is off. Cylinders havent been allocated to trim tables. You can either assign 1 table to each cyl for indivual cylinder control or assign all cylinders to 1 table to retard all together. Set retard limit to 0 while tuning so it doesnt work against you. DanSJ80 1 Quote Link to comment Share on other sites More sharing options...

Adamw Posted August 15 Report Share Posted August 15 Negative knock level detected means your knock level is below the threshold. DanSJ80 1 Quote Link to comment Share on other sites More sharing options...
