Here is stage 1 file for golf 4 1.9tdi ALH. Password is: bojannnn_05/03/2024_VE90

questions:

- why the pumpV changes?
- TL aggressive to say the least, this is what I hate about stages, that TL will kill stock clutches in no time, I'll be surprised if it lasts the day. if you want to preserve the stock clutch you can look at the stock ASV TL, plot it, now see where it starts to taper off at 1995rpm? keep that same angle and just keep going. you'll be stock at 1750 and below, slightly higher at 1995, and then keeps getting higher until you max out. plot your DW and SL on the same chart as TL so you can see how they interact. I also plot SLxBoost, so I calculate MAF from my boost target, and plot that as a more realistic SL because that'll actually be telling you how much air you've commanded
- SL you're limiting below TL, you want DW > SL > TL. TL should be the lowest on your plots, you are plotting right? Also you're looking at around 19.5 AFR, you can go lower. Course you're not really around that though are you ... because you messed with the pumpV for some reason.
- Boost target looks good, I goto 2150 at sealevel but thats just me, its very close to yours. Im not at sea level though, so I use Boost limiter to properly adjust for that. Factory doesnt but should.

Updatelee Thank you for your response! I am not a tuner, i got this file from "pro" tuner and like other files that I upload i paid for them. On my car tune worked well, guy said that should give about 120hp, i agree with you about clutch, but once again I am not a tuner and I see that you know this things well. Really appriciatee your response, I am willing to learn this things. Perhaps can you help me with stage1 for my corsa 1.7 dti? If you look my posts you will find file and Id, once again really appriciatee respons!

I would be concerned, or at a minimum ... question, this tuners ability. Strange changes dont instil confidence.

I sold car with map ON, but i gave original file to the new owner. Like I said with a normal driving I did not feel anything strange, but I believe to ur words with fact I dont know much about remaping. :)
