My fuel trims have been kind of crazy lately and I cant seem to get them fixed using latency or scale. I was reading through the MAF Scaling threads and decided I might give it a try. I open up my MAF Scaling table and this is what I see:



Call me crazy, but this doesnt seem right AT ALL. Please keep in mind that I have NEVER touched this table prior to this. Actually, this is the first time I have ever even operated ECUFlash in anything but "Beginner" mode.

Can someone please explain to me why my table looks the way it does? I have tried to view some other tables and tried to mimic them in trial maps, but I cannot even edit the Load values to above 6400 units. I assume that something has been altered in the edit map values, but I dont even know where to start to try to find this. This was a base map for my 50-trim kit that I have adjusted (injector scale, fuel maps, and timing maps are all I have touched really) that I got from someone else and unfortunately, I do not have any stock maps saved on my new laptop.

Some help would be greatly appreciated! I am maxing out my short term trims in the negative percentage (-25%) and still getting a bank 1 rich CEL. I have a feeling this MAF Scaling table is the culprit.

Thanks in advance!

 

Is that ECUFlash 1.29a or is it 1.28?

1.28 gave my rom unusual stepper values

 

this is 1.28

I didnt realize there was a new version out. I suppose I should d/l it and start with a fresh stock map and see if I cant get better results.

EDIT: Can someone post a stock 03 hex file?

 

I got the ROM file. MAF Scaling looks fine on this new map. Will try this one out.
