Is that the original pocketlogger from digitaltuning.com? The OBD2 version? If so, mine doesnt have that neat little dyno feature on it. Well at least I havent found it if it does have it.

I wrote the dyno feature software and it is not for the palm. it uses windows command line.
If I have more time, I will try to make this to full blown free application with fancy windows gui or something. But, I am lazy and command line tool is good enough for me.

 

taenaive look your evo is knocking bad. the timing is onyl peak at 15 degree

 

Did you even look at his timing maps?

 

Although he is just being nice by providing his map, please no one grab this map and upload it without tweaking it just my 2cents, then someone will be saying "I used taenaive's map and my car blew up"

 

So... I'm not seeing any significant changes between your fuel maps and those of the reference map from openecu. I'm just curious where you picked up the power from, I do see a few tweaks in the timing map... did you scale down your larger injectors (I know the scale factor is higher than stock but is it low enough to lean out the mixture a little up top)

 

that few tweaks made the big difference.
I had to scale injectors because I have 680 cc injectors.
chainging 1 degree of timing can yield like 20WHP in some cases.

 

Not with you maxing out at only 15 degrees it ain't. Maybe -20whp

You have less timing then stock at trq peak, 5000rpm and up top. Are you running big boost or something to make up for less timing?

 

21 psi is too much boost for 91 oct on hot california summer day. I can't go any higher without richening up the fuel or lowering the boost. I found that lower timing and more boost or lean fuel makes more power.
15 degree is not bad. I can do 12 degree and make more power but I get too worried about cooking my exhuast valve. --Good for one time drag race though

 

I am working on the revision of this map. I will try to do the rich tune with more timing. I found that 620 injector scale value was no good. It gets too lean when there is not much load.

 

You need to change the battery compensation too.

 

has anyone found the proper values for the larger injectors?

 

I haven't yet.. But it allows you to scale your injectors and balance them for different RPM's (voltages)

I'd like to figure them out for 1000cc injectors, I got those going into my car this weekend..

 

I played with it just now.
best I got was to multiply by 1.8 for the latency. and injector scale value at 605.
I am going to try something like 2.0 and 636 later. It was still bit lean low and bit rich elsewhere but It was much much better than before. My laptop battery died for good in the middle of the process.

 

I settled with 636 scale and 1.8 multiply over stock latency. Now I need to learn How to change the load level. my load level always ends up at the most highest of the map from 3500~6000 rpm when I do WOT on the road. I think it contribute to my high MAF reading. Well, I am making about 100 more horsepower than stock so I guess this is expected....
