Have you seen High Performance Academy its worth a look. They have webinars on setting up e-throttle idle that may help.
-
If the numbers in the Fuel cells achieve the lambda target valves at normal operating temp i would of thought the issue lies with your idle solenoid and idle ignition advance settings. What idle speed and lambda are you trying to reach?
Also are you using closed loop idle or open loop?
-
Go to HELP, ECU information,
Ecu Enabled: Should be Enabled not like the pic i posted.
-
Could you post a log we could have a look at? And a pcl file?
-
What are you injectors like at low pulse widths? Could they be working in a non linear area?
Are you using a idle ignition table?
Also have you tried adjusting the charge temp compensation table instead of disabling IAT compensation?
-
As Steve mentioned G4 only has 12 general purpose tables as listed by LINKS G4 ECU matrix. I'm sure Scott or Simon can post it up again for you.
-
So your mate bought the cheaper G4 and expected the same features of the G4+?
-

For some reason i can only chose a Digital input up to 12 to activate the speed limit. Any chance we can get that change up to 16.
-
Thanks Scott.
-
Any chance we could get a automatic notification when there is a new firmware release.

What is the injector duty cycle at 5000rpm? If it was me I would be setting up a GP limit 3D table with rpm and injector duty cycle. To control rpm limit at high injector duty cycles.
-
I thought there was another thread with a similar issue which had to do with too high of injector duty cycle.
-
With ECU on check the runtime values for all the individual Battery voltages. On my thunder when wiring it I stuffed up the ECU hold wiring. Wouldn't get full battery voltage and ECU would still have slight power when ignition switched off.
If u post ur file I can test it on mine
-
Would it be worth while having a value option where it would reduce ignition then reduce fuel over the set valve, and vise versa for fuel cut.
As example have a limit of 10 Deg ignition cut. If all the compensation of RPM, IAT, Water Temp EGT temp add up to 15 deg you would get 10 Deg ignition cut then 5% fuel cut.
-
May i add to have 4d and 5d tables and many other tables setup as afr compensation overlay. For example i like to add some fuel at high IAT's and high gears.
If I use full time closed loop control, i need to adjust the afr target accordently. Otherwise the closed loop will remove the additional fuel on high iat ( overlay target already used for gear compensation).
similary on warmup of the engine. Most engines run smoother during warmup of we use a bit richer mixture.
In the modeled mode doesn't the IAT temps get automatically compensated as part of the Gas law? Theoretically If you set the IAT as a 3D table with gear you should be able to Increase fuel compensation over the closed loop Ftrim limit.
-
yes as I've written I'm usually use the target overlay already to do gear compensation (Lambda Target Table Overlay spanned Gear or Speed vs RPM)
So i need more tables to alter the target. Otherwise i can't use full time closed loop control. Usually it's a good idea to rich mixture up on situations that are prone to knock. (high temps and loads)
If your max lambda Ftrim limit is set to +- 5% and you want another 5% trim for high temps why cant you just increase the mixture 10% ?
-
Thunder has the same feature.
-
All sorted, Cheers.
-
If you go online it shows the new PC link but still cant set injector dead time data or min effective pulse width and pulse width adder data.
-
Is anyone else having issues loading this firmware? It downloads and runs fine but it is not showing as a available download option in the firmware updater.
-
Dose the 1450cc injectors have a diffuser plate?
I thought ASNU made injectors for FIC. Might be worth while contacting them for the data.

ECU unlocked?
in G4+

That map looks to be one of my old ones and was setup using hall sensors for both can and crank. Are you using Hall sensors?
