Which tables are best to copy first? which have the best bang for the buck. can I copy from the Ao1I calibration even though its different than mine?

You should only copy things you want to fix. If you don't know that you need it, don't copy it.

Stg1 typically doesn't need changes.

I'm looking at waynos roms and i see there's both a Stg 2 UEL 98 v101 AU "LEAN" and "RICH" version. I live in Vegas which would be more appropriate for me?
When I compare my rom to say Stg2 UEL 98 v101 AU Rich A01G.bin there are 242 equal tables, 73 changed tables and 94 missing tables. Do I just copy and paste the 73 changed tables from Waynos to my rom (F00C) and i'm done?

Depends on where you want to start. You need to dl the defs he uses, otherwise you will have tables missing that you can't see from his roms. I found this out, still new with this setup, thought i could just use the ofs defs. I believe some tables might still be missing though, fyi, but i have seen the important tables (i was wanting to look at anyway) are there for both.

Personally i know it gets HOT here in az, 100-125f temps out on road, if not a tad higher. Its a dry heat though, so humidity is super low. A bit different there then vegas. You can change Timing Compensation (IAT) 86 do -0.70 and 104 do -1.41. (i have noticed a change, but i have changed over 10 tables so far in the tune) still a work in progress... haha. So far on our crap 91 here, my tune is running ok, think i fixed the issue with with it going lean for a short bit from CL to OL as well.

Have you ran the reg stage 2 ofs tune yet to see where you sit? Scaled your MAF yet? Or ran through wayno and steve99 guides? I wouldn't copy the tables directly, different defs, might mess stuff up. (i haven't to be safe, might be ok, again im still new to this) I use a screen clip (using sniping tool) of the table or parts of it that I want and then manually entered the numbers. Doesn't take me long as I input numbers all day long, lol. After this you can load both and check to make sure you entered them correctly with the compare tables.

If you want, you can use the Base timing A, Base Timing B, Knock Correction MAX A, Timing Compensation (IAT), Timing compensation IAT (Activation), front oxygen sensor scale change (make sure to change the axis as well), rad fan change. (or copy all the tables)

Drive and log the tune lots, i usually have 4 or 5 logs a day, lol. This way you can see whats going on with different temps loads etc, but let the computer learn 1st (unless some major lean or rich or to much knock) otherwise if you make little changes it might be for the worse instead, lol. Just to start off. =D So far im really enjoying this great tool.

Currently still running the base OTS stg2 UEL 91 rom. Have not done a MAF scale yet for my drop-in filter and Zeta silicon intake pipe either. I don't even know where to start. I'm new to all of this and trying to read and understand it all is getting quite complicated. I guess I just have to understand how the engine works as a whole to to know where to even start to tune and what else needs to be adjusted with it at the same time. Might be better for me to use someone's tune what was made in a similar climate as me to begin with. I'd done many logs and seen some knocks here and there but when I do another log the there is no knock at the same instances so it's like I don't know how to tune to improve things.

Before you start messing with a tune, changing it, etc read lots, it helps. You can even go into Romraider and look at the values, check out different tunes, google. It will take time to understand, but its very doable even for a novice imo.

If you start on wayno, and steve99 links in their sigs, wayno basically gives you a tune to copy for the 91 gas, their gas 98ron. Might need tweaking, but its a good starting point on all those tables atleast. They give really detailed and straight forward info I think anyway.

Oh the 91 gas its horrid so I have come to find out. Now if its not knocking over -1, and its not doing it all the time. If it is more then -1, that is something you need to look at right away, probably happening alot. For either, look at what instances it is, engine load/throttle position/commanded afr vs afr to see the cause of it. You can start from scratch with wayno's stuff and adjust things to how your car runs works etc. I think you will enjoy it alot as i have, its an amazing little tool so far I think.

@Wayno just noticed that in v101 A01I, that you don't have UEL_Tomei 98/E85 files anymore. Would the v101 UEL98/E85 be fine to use for reference for the Tomei header as well? Or should I still look at the v100 Tomei files?

The only difference was the load limits. You can lower the value at 3800 if required, or leave it as is. I don't think you lose power leaving it at 1.02 for E0 and 1.07 for E10/85.

[Tomita San]

Maybe I don't get it quite right, but if i would like to use the mods from the v102, should I use the defs in the zip file -v101 2016-04-27 linked on the first page, or the original OFT defs i am running now (UEL stg2)? Btw. I am running 98/100 RON.
Also, what are those KN metric and standard DEFs?

[Wayno]

The latest ones have the latest date in the name.

So i should always use the lates defs (from the v101 file)? Just curious what are the differences.

[Tectoniic]

I've read most of the thread and didn't see this so I apologize if my 2 questions have already been explained but I'm trying to solve some high LTFTs at idle/low speed that seems to be related to IAT so I think the below changes will help?


There are 4 tables referenced in the OP related to coolant temp for the fans. Do I need to change anything regarding turn off at 70 kph or do the fans already turn off at that speed anyway?


Can ztans di/pi fix http://www.ft86club.com/forums/showp...6&postcount=21 be done without doing any of the other changes in this thread? I get a bit of stumble at low load while cruising and idle and it looks like this should help. (I'm 2015 AT that has already done the TSB for dip at idle/park if that matters)

With those fan tables you just changing the temps where the fan switch i believe their are other tables not defined that alter the speed where the fans switch modes.

yes you can alter the pi\di ratios as per ztans post without other changes

- D00G, E00I definitions now have Front O2 Scaling B and all 10 cranking tables.
- "v104" has a smooth AVCS maps, "v100" is close to the original openflash maps.
- Other minor changes.

[Wayno]

Updated
v104
- Fixed AT bogging after shift in 2000-2200 rpm range at high load. Can still happen rarely at medium load.
- Other fuel and timing tweaks.
