The map with yellow and green circle of the post above are the same! is KFZWMS

Thanks for all that help me!

I will make a map address list and post here soon for help the others that have the same engine code (BBG)

When i edit KRKTE in 8bits, just the address 0x1CF84 changes, but when i edit in 16bits, the next address (01CF86) change too, why?

I found TVUB 154d2!

Thanks!

You must have set something wrong. 16 bit mode should change bytes 0x1CF84 and 0x1CF85.

What exactly have you changed to run E100 hardware-wise? Just injectors? Are you running different fuel pressure regulator? What about setting timing?

And question to ME7 gurus - how will whole torque model work with KFZWOP(2) screwed (as it was set for petrol not for E100 so ignition advance impact in torque calculations would be completely wrong)?

Short answer: KFZWOP has to be rewritten for E100 or race fuel. E85 is usually "close enough".

That is what I thought Cheesy

Next (obvious) question - how one without engine dyno and all equipment used by OEM calibrators would prepare proper KFZWOP? I understand we could estimate it just by offsetting it by same amount KFZW had been offset for same load/engine speed but I am not sure how far it would be from proper optimal ignition timing... At least here we are talking about naturally aspirated engine when it should not have so huge impact but still I would try to do my best to set it up properly.

Yes, that is the challenge. There isn't an easy answer to this. The bottom line is that pretty much 100% of tuners that do not have access to an engine dyno have no choice but to guess at it.

I have seen many files made by "reputable" "pros" for many different ECUs and all I can say I am disappointed by their work. Some of those file were quite expensive and still were made easiest possible (not correct) way - for example by decalibrating injection duration in diesel engines - if I would like a power box I would buy one, if I choose ECU tuning I want it done as it should be done.

Regarding ME7 all I saw is that even those "reputable" "pros" lacks understanding of torque driven ECUs...

You also have to understand they simply do not have the time or resources to do everything the "right" way. They have a lot of product to ship and a constantly evolving catalog of different ECUs that have to be reverse engineered, year after year after year.

It is not an easy thing!

I criticize "pro" tuners all of the time, but if I'm honest, they simply can't afford to do everything the "right" way. They'd never stay in business. The DIY guys have the luxury of not worrying about how long a tune takes to do, or how long it takes to really figure something out...

IMHO no one is capable of doing all ECUs on the market. That is why no one should try to do so. I would just stick to some ECU families (or even cars) but do them properly.

I post that KRKTE in 16bits changes the 0x1CF84 and 0x1CF86 (sorry), but its wrong, in 16bits changes 0x1CF84 and 0x1CF85

For E100, i change the original injectors for a injector model with 18 holes and 55% more flow rate (model FBY2850).

It edit KFZWOP for more 6º in timing (E100 needs to advance +- 6º in ignition timing), i make the same in KFZW.

I change KFZWMS too, but i dont know if causes efects in E100.

For injector with just 55% bigger i believe that don't was necessary to change TEMIN, i just will change if the idle stay rich after i found the correct value for KRKTE

for E100, the engine need a flow rate 35%/40% bigger.

How many bits are in the byte at 0x1CF84?

According to my data E100 requires ~63% more fuel, as its stoichiometric AFR is ~9.0:1 (14.7:1 for gasoline). It looks even worse if you compare rich best torque figures (AFR ~6.43:1 for E100, ~12.5:1 for gasoline) - it is ~94% more fuel.
Taking that into consideration the injectors you are using are too small IMHO.
