Well the only explanation I have found for the above 100% idc is that the formula used to calulate it is not correct so 100% idc is not really 100% but more like 80-90%

 

I do have lean spool in my ROM, never opened it up tho, what do i need to check for you? im pretty sure its set off, or at a value too high so it doesnt activate. What does lean spool do actually?

 

From the Evo 9 2-byte/lean spool thread:

Lean spool creates a wildcard for tuners. By disabling it you don't have the ECU messing with the AFRs against what you've tuned for in the tables.

 

Thanks senete. I have lean spool start RPM at 62, and lean spool stop RPM at 62, so im guessing its disabled.

 

I'm not so sure, with the whole big endian, little endian thing....those values might be somehow incorrect. 62 seems like a weird value, perhaps up the load in the "thresholds" for lean spool all the way up just to be sure? I dunno, it bothers me like crazy that some of those numbers in that auto ROM don't match the right thing in the XML.

 

Yeah can someone please explain what the "big" and "little" endiens are for? I dont think there just for viewing the ROM image anymore because on some of the values i have gotten this message when trying to change the "data endian" value "THE FORWARD AND REVERSE SCALING FUNCTIONS YOU HAVE SPECIFIED DO NOT APPEAR TO RESULT IN THE SAME VALUES WHEN PASSING THEM THROUGH BOTH FUNCTIONS. THIS WILL CAUSE INCORRECT INFORMATION TO BE DISPLAYED AND WRITTEN TO THE ROM WHEN USING THIS SCALING. DO NOT USE THIS SCALING UNTIL THE PROBLEM IS CORRECTED."

And just a FYI, my tephra ROM is all in the "big" "data endien" but i cannot read the values correctly if they are in the "big" option, i can only read the ROM values if there displayed in the "little" option, but sometimes i get that scaling error message when trying to change the endian. Here are the values/ scaling i get the error message when changing the data endian.

-"MAFhz" error changing from "big" to "little"
-"AFR" error changing from "big" to "little"
-"AFR16" error changing from "big" to "little"
-"AFRwideband" error changing from "big" to "little"
-"Percent16 (256)" error changing from "big" to "little"
-"TempScale" error changing from "big" to "little"
-"TempScaleFuel" error changing from "big" to "little"

 

I dunno dude, I kind of had the same sort of feeling. The scalings are there to interpret the data, so while displaying the data improperly will not cause problems.....editing improperly displayed data and flashing it will cause proplems.

I only see the MAFhz scaling in use in 1 spot, don't just change from big to little unless you are seeing incorrect values. If you have a scaling that doesn't seem to be working, instead of fooling with the one that's there, open your original rom, and see what scaling it used, if you can. AirflowHZ is what is used in lieu of mafhz on the base lancer, and it looks great when I swap it into place on your ROM.

*Edit* oh, and if you change teh scaling used for your lean spool limits, to RPM, they show up as 2000....but the scaling you have matches what's in my tephra rom. What I think the deal is, is that the lancer stuff was copied in, it's still a lancer rom, but the evo stuff was merged in, so the same scalings that work for the evo aren't right for the lancer rom....I wish there was a way to put the actual evo rom into an auto, but I guess what you have is the best solution. This is my theory though on why you run lean up top...it's not really a evo rom.

 

Yeah its more of a lancer rom with bigger maps really. I changed my lean spool to start RPM for 9000, and end rpm for 9000 so it shouldnt take effect. Is the scaling you attached, what you want me to put into my ROM for MAFHZ?

 

Does anyone have a stock lancer oz ROM? 2002-03? i cant seem to find my bigger version of my stock rom, i only have the small version saved

 

create a new scaling called airflowhz, and use it ibstead oh mafhz when you need it.

 

Ok gotcha, and hey hows your timing in boost, hows the accel feel? Im at like 1 to 2 timing advanced in boost from like 2,700 all the way to 5k. At 2,500- through around 3,700 the car is sluggish but from 3,700+ it pulls significantly well, even at 1 to 2 timing advanced with no knock in the upper RPMS. Why does my accel suffer in the lower RPMs? is it because timing is so low? do i need to smoothen it out, like maybe from 2,500 increase timing and gradually lower it to 2 timing advanced around 3,700 range?

 

Well...that's a tough question. If you are still lean in that area, then you shouldn't be driving at WOT. Having a high AFR could cause damage such as melted pistons, or high pressure due to detonation causing rods to go *snap*. What's your AFR when you feel sluggish, and at the upper rpms, still 14?

 

AFR when heavy accel in the sluggish area are 12's and when WOT all the way when it starts to get "fast" the AFR are 13's so i still need to work on them some more, a combo if the fuel map and MAF scaling seems to be bringing the rich mixture up top

 

not understanding how to tune this fuel map, when I accelerate at WOT I go straight to 10 and it leans it self out to 11.1, technically it should be backwards going to 11.8 then richen out to 11.5-11.3. Need some help on tuning this portion, the timing is easy enough.

you think I need to raise my maf scaling and see where that takes me?

 

You could try lowering the MAF values in the areas that your getting 10 AFR to lean it out to where you want. For me MAF scaling seems to be the only way i can get rich enough in boost
