Hey, I'd like to increase the power in my Audi from 225 hp to 250 hp. I want a safe map, not a maximum hp limit. I run 98 octane and LPG. So, I'd like to ask which maps I should change to get 250 hp? Of course, I've taken care of the car mechanically, the turbo has been rebuilt, the intake is tight, and there's no SAI or N249. Thank you for any help  Cheesy

Keep reading... it's very simple to add a little power to a 1.8t.

You have everything you need.

Choose one fuel.
LPG will be more complex to tune, I think, but I don't know anything about it.

If you're willing to learn, you'll get help.

But no one here will do the work for you. Grin

I did this with LPG in mind, to be as safe as possible. I wanted to achieve good low-end torque rather than top-end power. Tell me what you think?

You're going to destroy everything with percentages!!

You lowered BTS?? You're just going to flood your 700 EGT engine with a wave of fuel.

You increased IMX by percentages! 104%... this is a duty cycle map!!

Take the time to read...

Use me7logger to understand... without logs... you won't get far.

Okay, I understand, so I'm changing one map – logs and changes. Which map should I start with? And how often should I change the values?

I would say: 1. This won't be learned in 15 days. 2. Understand the basic operation of the ME7, starting with the action on your pedal. 3. Always perform checksums before writing. 4. There are several ways to do this. Start by adding fuel at high load for WOT safety. You can use LAMFA or BTS. LAMFA in relation to your pedal. BTS in relation to EGT. Logs, readings... You can play around a bit with LDRXN and then adjust KFLDIMX if needed. There are, of course, many limiters on the ME7. And your equipment will also quickly become limited, especially your injectors. You have narrowband, so less precision... Logs, readings, logs... Record knock and fuel... Above all, you must know what you want. If you're willing to spend hours learning and reading... or you can simply pay for a fixed setting. (Don't try putting 200load in a KMIOP file; it won't accept a 512k file.)

lamfa is also misaligned in your .kp file. I think 1b2E8 x 1b2dc y 1b2cc
