TephraMod V7

Any idea why the defaults for the two Cranking Enrichment IPW adder tables would be so different? See attached. I assume the Alt table is correct and the main table has bad data, am I right? And the two different table sizes, is that intentional?
Maybe I'm simply assuming too much, as I assumed the new V7 96530706 had the very latest Mitsu defaults, so I have been diligently NOT changing them to match my old 94170014. Is this not the case?
96530706 has been working out pretty well for me, but I'll go along with the idea of having only one USDM ROM. I thought the 9653xxxx was a USDM ROM, is that not the case?

After taking a quick look again though 9653, I have found about 6-7 tables that are different (from my 9642 ROM). They just might be scaled wrong, defined wrong or they are just plain different. And we dont even have every table defined. I would bet that there is a good amount of differences.
Regardless, reasons like this is why I dont use 9653 or put 9653 on cars that I tune.

-Also, since we dont know every single table for any ROM, there may be tables in 9653 that are different from the USDM ROM, that we dont know about.
-Another big reason to me is the "throttle hang" problem. The 03-04 cars dont have this problem and 05+ do(ie 9653). Also since no one has found a complete and perfect fix to this, the only way to correctly remedy it at this point is using a 03-04 ROM. After dealing with the "hang" in my 05 VIII and my IX, then gettin my 04 RS, that has no hang at all, im a lil reluctant to move to a ROM with that "dreaded throttle hang"
-Also I tune other peoples cars, and I dont feel 100% safe about putting on 9653, especially since I dont run it in my own car.
I do also understand that having to mod more ROMs, take more time for developers and such, but as I see it, one USDM VIII ROM should be mandatory.

It looks to me like it would be hard to argue that this is a problem. I set the idle exactly as specified in the US service manual and my car (and 04 RS) idles great -- better than it did on 96420008 actually.
I understand its a very very easy problem to fix. But to me it just goes to show that the EDM ROMS might not be as similar to USM ROMS as we think.
This is actually an argument for using only a single rom. The more people who use it, the more problems that will be found and fixed. 96530006 seems to be the most universal, so by that argument it will improve fastest.
yes, like i said in the other thread. I know that having one universal ROM, well get all the problems found and fixed faster and its better for the comunity. Im just picky about my car and would like to run a USDM ROM with V7 (also, read quote at bottom of post)
It's fixed on my car: two ISCV tables + the decel tables. Throttle response is just like stock.
I have also fixed the throttle hang on a couple cars using ISCV tables and decel tables, but when using those setting on some other cars, it didnt completely get rid of the hang and sometime causd cold start issues. (I also tried modifiying the setting a lil to no avail)
Also, people have seen that even after "fixing" it, the AFR doesnt shoot back up to super lean, like it should, showing that we have not completely fixed that problem.
? But would that apply to anything? Why do you feel comfortable running a tune that is different from your car?
I say that because I sometime tune others cars here in Cali. now I cant just load up 9653, tune and send people on their way, cuz IIRC the EDM ROMs do not have emission stuff on it, so here in CA, cars would fail smogs (when people he have passed with cams, upgraded stock-like turbos and other mods)
So many things have changed that I would argue that tephra's releases aren't actually US or EU roms anymore. Timing, fuel, and boost logic are signficantly different. It's strange to hear folks worry about the origin of the rom, but not worry about that.

All I did was ask if tephra would make a USDM V7 and I said I would donate more, even though I have already donated towards V7.
I guess I should have just sent my request to tephra in private and just paid him to do one V7 USDM ROM for me. Sorry

94170015 is probably the most defined of the VIII ROM ID's; I've converted to V7 and have worked out most of the little issues. The next one is throttle hang, but I'm sure I'll figure it out. I'm all for a universal USDM ROM, but think all V7 issues can be remedied rather easily.

The transition to v7 96530006 is rather painless, at least on my 03 it is. Sure there are tuning differences, but all that needs to be done is to ensure that you transfer your stock table values into v7.
There is a lot of difference between each rom. Therefore each rom has is't specific needs to run your car properly. The v7 rom works wonderfully! You just have to take the time to TUNE it properly for your specific mods and stock rom.
I too fought tooth and nail for a USDM universal rom 94170015, but after making the switch to v7, I regret any turmoil I may have caused. My own ignorance was stopping me from enjoying the best "stock" rom available.
The problem is that USDM models differ every year.... 03 to 04 the turbo hot side changed.... 04 to 05 we got ACD...05 to 06 we got the IX. There is no way to make one rom cover every model and work great out of the box. Thus the need to TUNE.
My car runs better now than it did when it was stock. Smooth, starts on the first crank, idles well, and pulls like hell. The best part is that drivability has improved to a point I get 23-26 miles per gallon. My car stock never did that.
Take your time and TUNE....you will be elated with the results.
