I know that 700C should be directly compatible with B01C as the OFT OTS tunes just use the B01C tune on my car by changing the model code in one location. Should I be able to change the same value on your B01C tune and everything would work, or would that just brick my ECU? Thanks.

That should work so long as you do the change correctly. I don't recommend trying unless you're technically adept.

If you using Tactrix yes you can just flash a B01C rom to a car originally a 700C as its compatable

If you using oft the oft wont let you as it want to load 700C roms only. Yep the oft guys calid hack the B01C oft roms to look like 700C so they load. But its not as easy as just changing the calid string in roms theirs a few other characters to change as well and you only do it in 2 out of 3 calid in rom.

The best way for you is to use romraider and transfer the tables over to your oft 700C rom which is actually a B01C.

If your confident with a hex editor and romraider PM me and i can send you the exact address ranges to change in rom.
However your going to end up needing to be very carefull with definitions

Maybe I am completely missing it because its so late and I am exhausted from work, But which .bin file should I be copying tables from if I am Stage 2 UEL running 93 oct w/ AT?

I see one zip file has all the Lean .bin files and the other zip having all the rich, But the only us .bin files are e85. The rest being 98.AU.

Its been forever since I've even messed with my OFT so i figured it was time to do some tweaking. Just want to make sure I'm not completely overlooking the answer to my question before I go flash.

Updated roms and defs.

I will transfer these roms (including launch control for D00G, F20P, etc) to other cal codes for $50.

I Just did the E85 EL for my 700I. (Using the OFT E85 EL as base)

Could someone check everything i've done is fine ?

Some table are marked as different but they are almost the same (just the RPM range extend a little bit 7200rpm on Wayno 7600rpm in OTS)

If it's good , feel free to use them (if not i will delete them)

You better off using the A01I rom as a base if you flashing with Tactrix.


The oft 700I is actually a A01I internally anyway. (they just keep the 700I tag due way oft works)


If you have tactrix just flash the A01I rom to car its the factory update rom anyway and has idle , cam and DI seal/transient retard fix done


just flash wayno's A01I and your good

[Camsheim]

Yep Auto but i use the OFT. So my base ECU is 700i and i have to flash a 700i :/

ok,


then you will need to fix up those tables, you will need to change the axis on the tables so they match.


you can do it easily by using the copy table function then paste, rarther than copy selection.


or edit the axis manually.

Ok , I did it.

There is just 2 hicups :

First : RomRaider tell me the table : Front Oxygen Sensor Rich Limit is different but the 2 tables are identical (10,0 on both)

Second : I haven't the Table : Front Oxygen Sensor Scaling B (Do i realy need it need it ?)

Yes you should do both 02 tables in the rom

use waynos defs

Yes sometimes romraider reports difference when their is none but check carefully.

also when copying single row tables it appears its better to highlight the values and use copy selection, for mutirow tables copy table works best

[Camsheim]

Ok. It finaly Match Perfectly

I Will try the Map after work. Monitor the first few km, drive around for 30mn and Datalog

Thanks for the precious advise

Files updated.

There's now 2 groups of files.

"Legacy":
- Petrol: stock injector ratios; 100% direct from 2800 to 5000, 20% port above 5000.
- E85: 100% direct injection at WOT, as per openflash E85 tunes.
- There are 2 different MAF scales to log and choose:
-- "Lean": based on stock MAF scale and the default for 6AT.
-- "Rich": based on Openflash Stg2 MAF scale and the default for 6MT.

"New" (experimental):
- All files have a single MAF scale based on stock (E85 is scaled up by 6%).
- All files run a static 20% PI at WOT, thus have a static LTFT value in that range and with luck should be faster to adapt.
- Provided I've massaged the values around 3V so all cars produce the same AFR's at WOT, I would consider these safer long term due to more fuel being sprayed at the intake valves than the "legacy" files.

After 200km, you target AFR's above 5k are:
E85: 12.5-12.0
E0: 12.0-11.5

Hey how do you log AFR commanded AFR fuel system status advance mult. FLKC? I dont see those listed under the realtime data in OFT? Thanks for the help

Ok nevermind. After playing around with the OFT a bit more i found I had to go into the "vehicle list" section to find those PIDs. I was going into tunebot!
