I have been following the EcuFlash thread on the midrange timing pull and how re-scaling the ECU to a load of 300 like the JDM ralliart and the Evo IXs ECU helped eliminate the excess timing dip.

Will re-scaling the 03-05 8 Ecu to a load of 300 give any midrange benefit to a Xede equipped Stage1+ and will it affect a custome XEDE tune?

 

This is my car's timing reported by obd2.
Just curious if anyone had any comments.

 

I havent read it all, but My timing gets down to pretty low in midrange as well and I am only running 20.5 psi.

 

At 3500 and -1* you seem to be in the 260% load cell. It probably wont hurt to rescale your ecu (to include -2* at 280% and -3* at 300% for added safety).

 

Holy moley thats some low timing around 3.5-4.5k, whats your AFR around peak tq?

 

Below zero. Theory is that the load may be off the scale at peak load.

 

~11.8 Peak tq
I run a stock ecu rom file, hi and lo maps are not the same and don't have the timing altered.

Log was done in 92*F temp, not complaining on power car just pulls in 3rd like a rocket at these temps. Still feels as strong and smooth as the day I got tuned



I downloaded my ECU rom and it looks like -1 is at 3500 & 260 load cell. I spent my afternoon rescaling the fuel and timing hi and lo maps.
I'll resume logging next week end with the rescaled ECU rom.

 

Yeah, I knew you were running the stock maps and that the timing is very tame on them. BTW, my hi and lo maps aren't the same either Interested in the new logs just to see if you note a difference.

 

What does your new rescaled map look like? Remember to rescale your fuel maps too.

 

Jorge-- Now post up your xede's timing map. Your actual timing is the combination of what you logged via OBD data and the offsets put into your timing map

-shiv

 

So it is: actual timing = obd2 timing- Xede offsets.

 

so if you have 20* - (4.3*)=15.7* thats low huh???

 

But he is also running smart, so the actual timing may be higher in some places and lower in others.

 

A do run smart but without positive timing, therefore runing more timing than what is on the MAP is not posible.
Logging timing offset from the XEDE becomes useful to find out how much timing is actually being taken out.

 

Do you have evoscan Jorge?
