Community Tephra Tweaking
Ok, so first, i did try reducing the injector latency value in the 11.75V and it didnt seem to do much unfortunatly :-( So whats the "limp home"? i see that table in my rom, but what exactly does that control, i noticed it was TPS volts and RPM? Also where can i find those values from the 9417 ROM, does anyone have have that rom so i can look at these values?
About the lancer base latency, mine is set at 000F hex, is that the same when you say 0xF?

The 000F is the same as 0xF the 0x is just shorthand for hexidecimal which is how you would enter it into ecuflash.
The Limp Home table is supposed to be a backup table if the car looses sensors and needs to fall back on a simple alpha-N strategy to keep the car running but get you home. The weird thing is this table seems to be used in startup and I'm not totally sure why.
The latency base is a multiplier which relates to the battery voltage value higher values mean more resolution AFAIK.
If you download the SD 9417 rom in the ecuflash forum in I think its post #2 it should have that table. If Not I can always post it.

Ok, thanks for explaining that info! ill go look for that rom, open it up and i want to copy the values in the "limp home" table in 9417 and input those values in my tephra rom's "limp home" table and give that a try?
Ok, i downloaded the rom in the tephraV7 thread in ecuflash forum, but for some reason i cant open it in Ecuflash, i have the deff files and everything im not sure what happened. I tryed to open the XML file to find that table but for some reason the data wasnt organized like the other XML's i have edited before, so i have no idea where that table is! Is it possible for you to post up that table for me RS? 
EDIT:: Also when i change over the values, is there anything specific i should be logging, other than what im logging now? (IPW, IDC, TPS, COOLANT TEMP, VOLTS, RPM, TIMING)

Also you can't have ecuflash open when adding definitions it only reads them on startup if you did you have to close and open it again.
Give me a minute and i'll post it up

Alright, thanks RS! i did put them in the right locations, i dont know what happened, it seems to work now. ok so ill copy these into my limp table and change my injector base, ill log a cold and hot start and report back!
HOT STARTUP AFTER CHANGES:
COLD STARTUP ADTER CHANGES:
As you can see, now im able to hit a higher IPW than 10.75ms. However, when the car was hot, as you can see in the screen print, the IPW stayed at 24ms and the car would not start, i had to push the gas in alot to get it to eventually start, as you can see the TPS% rises. Also, my WB displayed a constant 12.5 AFR when the car was warming up, and while hot. If i reved the car, the AFR would get up to 13.8 but bog out at 10.0 when i let off the gas.
Cold starts however seemed better anyways, as you can see in the screen print everything acted as normal. Let me know if you see anything i dont!
Any ideas? Should i try messing with the IPW vs coolant temp now, maybe lower the values and see if it will start? currently in the 190*F and higher im at 16.2ms. but the log shows like 24ms.
These logs are with the changes to the LIMP HOME and INJECTOR BASE.

Lets try getting your latencies back in check since we are now in this 0x18 mode. Just multiply everything in your injector latency table by 0.625 to convert it.
I do wish MrFred had some time to give me a hand
If you don't want to touch the latency we can just try setting the latency base back to 0xF
Once the car idles right we will mess with the startup
but idle first
Its probably bogging out cause we changed the injector latency base. At least it changed thats better than nothing.

Thank god its slow at work today, gives me something to do! (i work at KIA in the parts dept, SO SLOW hahah)
Alright spiker, sorry it took so long, i had to let the car warm up. I changed the latencys by multiplying them by .625, but they still needed some tweekin, so i eventually got it down to where i needed them, and to a point where it matches the fuel map exactly. Ok, so thats all set, idle wise, however it still hesitates to start, well it wont start at all if i dont use the gas pedal. Still the same 24ms at start so i tried to change the IPW vs coolant temp table and i changed it to 13.4ms and the log shows a steady 19ms so it made a change, but the numbers are far apart between the ECUflash value, and what the log displays, and even at 19ms it must be way to much fuel for it to start up, because it wont start without the gas pedal. Any suggestions? want a log?
EDIT:: screen shot and log added:

At least changes are making progress now lets drop those down to really small values like 1-3 ms and see if the car begins to act normal with that little fuel
Ok, ill bring the ms down to 3ms and start there and see if this makes changes. brb!
So, the changes do make a difference! 2.7ms i have at 93*F and higher, translates to 4.61ms in the log. Looks like it ups to 10ms or so when it starts, and it still takes about 5 or so seconds to start, but atleast i can make some changes in the IPW table. Any suggestions from here?
The screen shot got cut off but there was a point where the IPW was near 10-11ms before it started
