Those are 3rd gear logs?

 

Your 2-byte load def in EvoScan looks fine. I still think that your measured 2-byte loads is not correct though. I think that its your aftermarket airbox causing erroneous load values.

 

I would agree there but the i have looked at other logs with the stock airbox and load calc is the same.

so how can load calc remain the same and 2 byte be so different?

ye this is 3rd gear up a hill

 

Loadcalc will be the same between airboxes because it DOES NOT take into consideration MAF frequency. Since you only changed the intake and not injector scaling or latency or voltage, then loadcalc will not change.


2byte load DOES include MAF frequency. So if you change the intake, which WILL effect MAF frequency, then ECU calculated load(2byte) will change.

 

Did you estimate load from your timing table?

 

Hmm so you reckon i got to rescale the maf then!!!
OMG that is a ball acke and not something i want to do.

 

I don't understand what you mean mrfred??

 

Based on your logs it shows "Timing" of 4, 5, or 6 for 3500 RPM or above before 4000 @ over 300 load. It is very inconsistent while there were no knock sum count. That is very strange.....

If you look at timing table, what do you see for "Load=300" & "RPM=3500"?

I bet you that "LoadCalc" is close to the actual timing ran in your car (based on your timeing table - High Octane Ignition Table. I suspect that EDM ECU does not like 2byte-Load Mod...

 

No, I'm running 2-bytes load on EDM IX with no problems. It seems to really be a MAF issue (my car has stock intake - only filter is non stock).

 

Oh, I see.... That would make sense... Perhaps, MAF reading is fluxuating with aftermarket intake..... But... then, ECU must have interpreted around 300 Load (if 2byte load was accurate)...

Why would there be flexuation of timing when there were no "knock sum" registered? I really don't understand how it can have 4, 5, & 6 for "Timing Advance" unless there were knock sum registered prior to these RPM (3500) to cause timing to be reduced.........

 

Post your timing table, and I'll show you what I mean.

 

i understand what you mean!!

and yes it does seem as if my load and timing lines up but i will post up the timing table

thanks

 

please don't post the timing map if it's mine

 

then lets try rescale the MAF mellon
