ECU Question!

[Scott]

Yeah but the J spec stock ECU probably runs a less aggressive ign. map so would in theory be safer and therefore is less chance of det occuring.

the map is not running super lean over this level?

Plus if the fuelling is only remapped to 1.1 bar how do we know the map is not running super lean over this level?

 

To be honest it all sounds like if's and but's to me. I doubt it can be put down to the ECU unless it had an error. As Nic said, if the ECU detected knock it would have pulled the timing.

Do we actually know this or is this just hearsay? Surely the ECU will still pull ignition if it detects knock. Has anyone with a Mines, Blitz, TOMS, etc. ECU had their car dynoed and checked the AFR's?

 

Nick deals with Mines so could perhaps find out for sure what changes are made on the Mines ECU.

 

To be honest it is just hearsay as far as I am concerned.

The ecu obviously didnt pull the ign . on my previous car.

The pistons were seriously damaged and also the bores needed reboring due to bad damage.

Maybe my knock sensors were faulty?

Would be interesting to find out more about these ecu's with an afr gauge.

On the subject of ignition timing being retarded on std ECUs , i am still not convinced that it retards enough or the response is quick enough, i have seen det on my KS-3 yet the ECU has not pulled any timing that i could detect??

would be nice for somebody with a mines ecu to data log some runs with an external datalogging system.
