Did you update your evobase7.xml file and change the endian to big?

Looks to me like there is something wrong with the scaling entries for ECUFlash. Did the tuner do psi-based boost control? If yes, who was it?

It was me, I sent him the XML so it should work for him now.

Should have guessed it would be someone I knew. :-) I think he may have duplicate xml files in the rommetadata folder.

Well I checked it and I don't think that's it. I checked the scalings in ecuflash and I don't see one for "offsetwgdc" or "boosterrorpsi" like it states in the .xml file. Does this work for the 88590013 rom? When I load the rom in ecuflash it says it inherits from 88590013?

Question Mfred. Is the address listed for my rom used for Direct boost control / load ?
Reason i ask is because when i use the direct vairable address you note I get only wastegate pressure. Yes I used the "0x" before entering it...

I was given the address "0x895c" thats what another member uses and he says it works fine with the 2byte load. Thanks

I figured it out. The 0x895C is for the Load based tuning, and the direct boost is the other one....i'm using ROm 94170015

Hi to every body from spain!!

I´m trying to make the modifiation in a 96420008 rom, but the Boost Error correction and the Boost Adder maps , shows the psi values differents from the other roms on this thread.

On the next picture you can see all new boost control maps.

Can be an address problem???




Thanks and sorry for my poor english

Looks like your BEC is the only table off. Probably an address problem. Hopefully someone can help you out.

If you are using a newer version of ECUFlash, did you change the endian value from "Little" to "Big" in the scaling definitions?

EDIT: I am seeing the same thing with my copy of 96420008. I'll post a fix in the first post today.
