Evo 7 communication issues
 

Hey fellow Evom memebers, i know that i am gonna be flamed for asking what i am gonna ask but i searched alot and read alot with no luck.

I have a 2001 evo7 that i wanna start tuning myself, after learing alot from this forum, but i am having a couple of issues.

1. I cant get ecuflash to read my rom. Ive tried multiple versions many times with no luck with everytime having the same msg "cant connect to interface". I am using a 1.3u cable thats working with no problems with evoscan. I even can download my rom through evoscan with no issues.

2. I wanna use tephra's rom for my evo but will start with copying my existing fuel, timing and other important maps before actually start to miss with the tune. How can i copy my maps with regular scaling load cells to tephra's larger maps? Couldnt do that and when i try copying i end up with a single verticale loads with incorrect numbers.

Again sorry if my questions have been asked before, and i am sure they have been, but i couldnt for the life of me find a clear answer. Would really appreciate the help guys.

- If going from a stock rom, to V7 big maps, then you can use the bigmap converter file in the V7 thread in ECUflash section.
- I would suggest starting with retuning the factory ROM, or if you must mod, then the TephraV5.10 of 90550001. Its much easier to get a grips on tuning with the smaller resolution, as the bigmaps can get out of hand pretty easy if you aren't all that experienced.

yeah i was going with the 90550001 v5.10 rom but opted the use the V7 for the availability of launching maps.

i guess i should start with it since larger maps are a bit difficult to handle at my stage, but what about the problem that am having with ecuflash and not being able to read roms.....any ideas??

Have the correct XML installed?

Yup, but the issues is not being able to link ecuflach with the car at all.

Try ecuflash 1.29a and see if the problem is the interface key.

on 1.29a its working...... what should i do to run the latest ecuflash rather than using the 1.29a???

I'd just be guessing but perhaps you have a cable which doesn't have a proper license key. If you don't your sort of stuck with the 1.29a or you'll end up buying a key license which is the same as buying the cable again.

hmmmm.....well i guess i could always use evoscan to upload and download roms.

Would the 1.29a ecuflash work with tephra mods???

Should be fine.
