EM000 injector size location in rom

[lateshow]

As said I need to find out where the injector scaling size is in the OLD 7201F rom. This one's EM000 and it's from a 97 manual. Everyhting else is in the Kanji -definition. The factor im referring to lies in 10306 in the newer roms. But does anyone have any idea where this is in the old 7201F ecu.

i think it is 14663 in the 7201 def well that is the table address i have, i think the address in one of the defs that does not work is 04663.
i will upload the def file i am using for 7201 roms.


66063

hope it is what you need, i think this version of def was tidied up by jason foxdie as the original kanja def i got off jason did not seem to work.

Thanks, I have to convert one older vr4 to ethanol SO we can't use the actual flexifuel which was based on Kenneth's mod. We just have to modify injector scaling and propably cranking. Now i can see that the original message about Kanji defs was updated and there the scaling can be found too. I have to double check that since in some of the earlier defs with newer ecus that was ****ed up and there was wrong addres. Have to see that the address given now has the ecaxt same hex value as the right address in the newer rom...

Ok checked. 10306 and 14663 in the older rom give different values. Scaled with 29241/x the right stock value is 366 and the 14663 in the older rom gives 375. So no luck there. Bugger!

[Davezj]

sorry lauri, i am not sure is said the correct thing, the table address for the injector scaling is 14663 and the vale in the 7201 rom i have at that address is 375. the other stock rom i have has the injector scaleing set at 375 as well.

[lateshow]

Yes this is because you're looking it on the SAME WRONG place in the other rom. The address was something else than 10316 and I can tell you that that doesn't work. This is why it's wrong in the kanji def too I think :) So no ethanol for the 7201 yet :/ Try putting something like 250 when you have normal injector and IF it is the right value you should get an AFR of 10 . :)

[Davezj]

that is a great way of testing it.

[Davezj]

here is a stock def file, not a Kanji one.
it puts the injector size scaling table at address 00118 maybe it is this one, i don't have a 7201 to play with just lost of defs and roms i have collected.

here is the def file

66081

[lateshow]

Thanks, the new def gives the same value at 118 (375) so i think no luck there either! That one could be false too....

[Davezj]

what about 10306 and 10318 these addresses seem to crop up for injector size in a few definition files i have.

[lateshow]

10306 is the right address for the newer ecus and 10318 is the false address that people used. So they don't actually help much. We actually found A h8 for that mate so we don't need that info for 7201 right away.

[Davezj]

It would be interesting to know what it is.

if you find it, will you post it up.

by the way, i presume by your last post on any defs that reference 10318 i should be changing all my injector size table locations from 10318 to 10306.

[lateshow]

Yes you should if you're planning to use the scaling. :) If someone tells me the location of scaling, i will post that up.

[pbaron]

Address 00106 looks like it. If you could give it a try and confirm that would be good.

[lateshow]

seems legit. Gives the right value. Sadly my friend just managed to get an H8 ecu yesterday so we wont be testing this so soon. :/

[Davezj]

so which def file are you using for the H8 ecu my mate has this ecu and i just want to make sure i am using the correct one.

[lateshow]

The one you pointed out. Just replace the injector scaling's address with 00106.

[Davezj]

thanks Lauri your a star.

[lateshow]

It was pbaron who told the right answer. :) Thanks Pierre!

yep 0x106 is what I've got written here (0x200 less as 7201 doesn't have vector table)

need to make sure byte sex is correct in scaling (little endian for 7201, big endian for 7202/7203/h8)

thanks for sharing rep given
