The file is good ,try it!

This file is not even close to good and it will never make 210hp. The correct map names are:

injection at part throttle 014F05 14x14 - Maf sensor correction - this map sholud not be touched for normal remap
injection(ext) 0123DC 16x12 - desired engine load
lamdba sensor 018819 12x16 - one of them but which one :?:
spark advance at middle throttle 0160A9 16x12 - base ignition angle map
spark advance(ext) map1 0155FB 16x11 - optimum ignition angle map
spark advance(ext) map2 0156AA 16x11 - optimum ignition angle map

Missing - Optimal engine torque map and a lot of other torque limiters, a lot of boost control maps, correct lambda maps.

I totally agree with RPM freak. The problem is when someone test another file and feels little bit more power,
the person forgets to focus on engine running and behaviour. File is no good, period. :crazy:

Great, then guide me to make it better :) or give me some images with how should look maps for limiters and other stuff.
I want to learn this ecu because i love my car and i want to make it happy (not only to inject more fuel and give more boost).

My advice - Find ORI maps from 150hp, 180hp and 225hp models. The engines are simular (different turbos and injectors) but the map set ups are not the same. Find the maps you wont to tune and compare them in all the files.

I have a 150BHP AWT ECU.
I have software from BAM 225 BHP engine, i have my software, but i don`t know maps, offsets and where to start.

I Know that if i`m increasing IQ i need to increase spark advance that much to allow all fuel to burn completelly at 7 degrees ATDC for best performance. I`ve read some PDF`s about ME7 ECU, but here I want to have a synthesis of all datas about this ecu (ME7.5) with this software number, because i didn`t find those datas anywhere.

Hi I am new into this forum and just wanted to say hallo

good forum! also, have a good tuned TT 180 ajq map.if somebody want it

I`m interresed in that file.

I think i`ve just found some axis.

In 16 bit LoHi some maps have axis descriptors before maps, but some of them hasn`t.
I`ve been able to find turbo maps and axis only by viewing hex dump inside my web script. So, now i have some maps and axis, but what about factors and offsets? Is there standard for 7.5 or differs from a software version to another?

Thank you.

Found a map at 0x1c114 with the folowing axis values:
2400 6000 8000 10000 12000 16000 20000 24000
0 1638 3277 4915 6554 8192 9830 11469 13107 14746 16384 19661 22938 26214 29491 32768
What`s scope of this map and what factors should i use to make it human readable?

After this one, I have an 8x12 map with no axis, but immediatelly after that i have a descriptor of 14 values at 0x1c2d4:
10 20 30 40 50 60 70 80 90 100 110 120 130 140
This should be load (In %)?
