Does Delta Dash, or the ECUTEK programing software let you know the Injection Timing values ..... ?
If so, anyone knows if the IT values on the stock JECS or DENSO WRX ECUs are only RPM based or RPM and LOAD based ?

IIRC the LINK's IT values could not be changed so probably it uses the same values as the stock JECS/DENSO ECU's .....

They are load and rpm maps, ie 2D

thanx, and now what are those values ? ..... and most important of all can they be changed ?

I think Carlos is referring to when during the engine cycle does the fuel injection pulse start or end.

I certainly don't know this for the standard ECU. The only easy way to find out is to study the injector pulses with an oscillascope.

Don't know either, and don't have access to anything to alter them.

Paul, like you said I was refering to when is the fuel injection pulse starts or ends relative to TDC.
