Oh no, in this thread stands, that the soft rev limiter isn't enable in the rom for automatic transmission. :-(

Edit: Thanks to steve99 i'm sure to be able to make the necassary changes by myself.

Didn't know where to post this, thought it'd be helpful for people debating on going Stage 2 with a UEL header and wondering what kind of gains they'll see.

This is a virtual dyno comparison of the OFT stage 1 tune with a drop in filter, vs. the OFT stage 2 tune with drop in and JDL UEL header. (Also Wayno's load limits and PI/DI ratio)

Runs were done on the same level road, similar weather conditions, and no passengers, both set to DynoJet compensations. Therefore it should be fairly accurate in power/curve differences.
This is mostly just to show the tq/hp curve difference once you add a UEL header.

What website do you guys use to buy oft/ofh? I tried to contact shiv but no one ever replies.

He has been getting caught up with emails. So it may take him a bit to get back to you.

Hi,

Anyone know if it is possible for me to port over launch control/FFS into my stage 1 tune, from another tune for a different cal.id? I say this because my stage 1 tune (D00G) doesn't have launch control and there's no parameters for it in romraider

Also, cause I'm from Australia, I always use 98 RON octane gas, which I think is 93 octane for you guys in the US. However, there's no choice between a 91 octane or 93 octane map for D00G cars. Do you guys know what octane the D00G maps are optimised for, and if it's not 98 RON, is there a way I can optimise it myself?

Many thanks

No you cannot simply port over the lc\ffs patch . even though their are only minor differences in each rom (note the Tune is the same) when toyota\subaru recomplie the roms its shifts all the tables and code slightly so while the function may be same you cannot simply cut and paste code from one rom to another.

Remember all this stuff is reverse engineered and only toyota\subaru has the original source code

unless your skilled at decompiling ecu code with software like IDA, i am not unfortunatly you will have to wait for the oft guys to do it

all the G series maps are for the 91USA fuel version ie ok with 98. our 98 is only as good as usa 91, thier 93 is usually a better fuel. You will find it will knock slightly in places even though their 91 maps.

If you want to optimise it your self have a read of the logging and romraider links ect below. Then when you have that sorted, have a read of @Wayno tune threads

Thanks a lot Steve. Guess I'll have to wait for the OFT guys to give D00G maps launch control
I always thought 93 USA = 98 RON, which meant we had untapped potential with our tunes in AUS cause we run 98 RON but a 91 USA tune.

wishfull thinking, our 98 ron is pretty ordinary BP usually the best then shell, caltex seems a bit ordinary , united 98 used to be ok but have not used it for ages, their E85 is good though.

European 98 seems better than ours but out asian mates have pretty rubbish 98 like us

you might get flex fuel before launch control :-).

Those are my thoughts exactly! I only ever fuel up at BP, shell if I have to, and never anywhere else. One time I went caltex in an emergency and my car honestly felt way more bogged down than ever before...

I'll be ordering an OFH soon when the exchange rate gets better (more wishful thinking) and then running E85 from united + stage 2 UEL. Keen

Ive searched this website and couldnt find any early model stock tables. After working with romraider for only 2 months, I decided that I compared my original F00C ROM to what I'm working on lately. A couple of screens took me surprise as they are way different than what I'm used to seeing.
Does anyone know if the earlier ROMs were had similar tables? CL fueling only going as low as -.441? Or fueling having many more 14.7 cells? Or all the timing advance in high load/low rpm on advance a?

[steve99]

see the Tactrix thread below is got a lot of stock roms attached.

Just beware that oft roms are often not what they seem ie their calid is changed internaly and they have special defs to match.

if you want to look at those stock roms get the defs from the romraider site in the Tactrix post.

but dont mix and match defs, romraider ones for stock roms and OFT ones for OFT roms (also match the oft defs and oft tune revisions) else you risk bricking ECU.

CL fueling tables do NOT read afr they read the offset from 14.7 ie table say -0.50 actual afr target will be 14.7+ (-0.50) =14.2
do not put positive values in their else weird stuff happens and fuel trims get disabled
OL tables read AFR

in romraider read the table properties, and golden rule if you dont know what it does dont change it

sugest you read the Romraider Tips link as well

[Hyperblue302]

Thanks Steve99, I'll check out those links. I enjoy comparing different roms like oft, wayno's and stock against each other. I have noticed the ROM I'm running says F00C, but in car it says B01C. Kinda annoying to see but at least I got my mafv, flck, and iam finally working running e85.

OK, a couple things I am a little confused on with OFT- Can someone answer a couple questions for me?

-With an OFT stage 2 tune and a totally catless setup, does the OFT turn off the P0420 CEL with a standard stage 2 tune, or do I have to tweak the tune to turn it off? I have the latest 2.076 tune files.

-Can I uninstall the second O2 sensor if I am catless? I'd like to put my own wideband O2 sensor in that bung if I can, otherwise I have to install a O2 bung downstream.
