no afterstart enrichment?

Post by m0ntecarloss »

Should this come on every time you start your engine?

I noticed in megatune that it never lit up the ASE light at the bottom of the program on the main page. So I have been checking data logs and it never shows it coming on after starting the motor.



v3, ms2, code v2.34 (well actually unofficial v2.35)

I noticed today from a cold start that ASE was coming on.

So I'm looking at the code and I see:

Code: Select all

if(outpc.clt >= inpram.temp_table[NO_TEMPS-1])  {
    PrimeP = (unsigned short)inpram.PrimePH;
    AWEV = (unsigned short)inpram.AWEVH;
    AWC = (unsigned short)inpram.AWCH;
  }
  else if(outpc.clt <= inpram.temp_table[0])  {
    PrimeP = (unsigned short)inpram.PrimePU;
    AWEV = (unsigned short)inpram.AWEVU;
    AWC = (unsigned short)inpram.AWCU;
  }
  else {
Which leads me to believe the values for afterstart enrichment (and priming pulse) are dependent on temperature. But I don't see anywhere AWEVU and AWEVH are set except for in the constants table. And in megatune there is no setting based on temp. Is megatune just setting both of those the same then? And why isn't ASE coming on with a warm engine...


THANKS (this is v2.34 by the way)
