E98 Help

Post by bjohn118 »

Wondering if anyone could provide some insight on a Cruze with an E98 ECU os 24000207 cal id 55504292 and tuning with efilive. I am trying to understand how this ecu and os are determining it's injection quantity. I understand it's torque based but what pid is it referencing for torque calculation, engine or axle? Is it using predicted, immediate, actual, or delivered?

Tables B8802-B8803 commanded power tables say the table will be converted to a torque figure, but I'm having trouble understand it. Are the numbers in these tables a torque or horsepower number and what units are the values displayed in? There is also some contradicting info on the table descriptions, the actual tables list rpm or speed, however the description says RPM / Speed. The default scale doesn't lend itself to being an rpm or a speed value so I can only assume it's actually rpm÷speed=row axis is this correct?

Also is there a way to log injection mm3? The pids in the scanner show the injection quantity as not compatible. If not available is there some form of user math to calculate the mm3 or do i need to reference it from the B7001 injection pulse time table, and what are the different alt modes for?

Lastly the injection pulse times show tables A-H but doesn't give a description of when they are used and references B7012 pulse times individual however this table is not available in OS.

Hopefully this seems understandable and my questions will be easy to answer, thanks.

Doubt anyone outside the US bothered with the Cruze.
The Australian versions were among some of the biggest heaps of shit ever produced.

Search for the user 07GTS on the hp tuners or just commodores forum and send him a message. He tuned his Cruze using hp tuners and might be willing to help you. He installed bigger injectors and cranked the boost up to 20+psi.

same or at-least similar ecu used in the colorado's.

there are switches in the tune files which change what the torque reference uses & i've never looked into the cruise tune file.
