Hi to all,

Firstly, this file is not on any ECU :D ,
Secondly, I am still quite a newbie :geek: so ALL information is welcome so that I can learn from the many mistakes I make!

I am using VAGEDC Suite, I download a free original ASZ map to fiddle with.

Seat Ibiza 1.9 TDi
ASZ
2002 Reg.
6 spd Manual

I have now read a lot more about tdi engines and the various maps and what they do,
But, i still have some issues, I have been tuning this map today:

But once I open the performance menu on VAG EDC15 nothing seems to change...

Can anybody tell me what am I doing wrong?

Thanks

Easy :D you are using Vagedsuite? You have left the torque limiter (codeblock 5, 4D8AA,4D8AO) at low levels (standard?).....Vagedsuite is looking at this as the lowest mg/st setting and calculating the performance on this alone (the ecu will look for the lowest of any variable and use that too.
To be honest though, your tune looks to be miles too aggressive, I would lower most of the changes to less than 68mg/st and also keep the boost within a couple of hundred millibars from standard if I were you? This will probably smoke like a pig!

If you really want to take it to the safe limit of the engine, maybe consider maxing out @ 70mg/st all maps (in the higher ranges) and adding a couple of degrees to the start of injection at high RPM and high airflows and add a couple of degrees to duration maps 0 and 1, possibly duration map 3. Just keep it subtle rather than extreme as you seem to have done! :shock:

Thanks for the feedback kwempe :D

I had only altered Codeblock 2, not 5.

I have changed codeblock 5, and taken your advice and limited to 70mg/s.
Would you recomend I change all of the other maps aswell hey?

You also mention that the previous map would smoke a lot, not that this is a problem, but it would also hurt fuel ec. correct?

Thanks once again!

Version 3

Be sure to alter both codeblock 5 and codeblock 2, i'm not sure which your car runs on so be safe to alter both. Also (looking at both codeblocks) you still have some 80mg/st in there, way way to high for a standard turbo. I would keep the cars original torque and smoke limits below about 1800 rpm if I were you, it will save vibration when you are at low revs in high gears and save your clutch/flywheel too. Do you really want to increase your power at much below 2000rpm? Don't know about you but I tend to drive at 2000-3500 for fairly fast driving and rarely use 4500rpm+. You can keep fuel consumption good and keep smoke down in normal driving if you do this. Above about 4200rpm I would start to taper off too, the ASZ turbo is too small to supply enough air (safely for its own good) at very high rpm. I would also consider lowering values for lower atmospheric pressure to avoid overspeeding the turbo as the air is less dense at lower pressure and the turbo will spin faster to make the same boost. Torque limiter should be your first stop for this then the target boost and boost pressure limiter.
Why the 80mg/st spike on the torque limiter at 2247 rpm (codeblock 5)
One final thing, you have activated multi-smoke limiters. By doing this you have created 6 smoke maps when your original cars only had 2 (codeblock 2 & 5). I would go back and start with a fresh file, smoke limiters not activated until you have practised a bit? Multismoke limiters can be used to good effect if you wish to restrict your cars power output at very cold engine temperatures but are not much use otherwise.......
P.S I did say only add a degree or too to your duration maps, you will KILL your engine and it will knock like a **** with 45degrees duration!!! Go back to standard and make very small changes at a time. Can you post your original file by the way? Look for a PD 160 ibiza file and look at what SEAT did to get there, you can go just a little more than they did but not really too much. Your car is not going to make much above 180 bhp with its standard turbo, whatever you do to your files. Vagedsuite will only show calculated power not actual if your hardware is still standard.... :)

Seriously, Thanks for all your help! :angel:

I have managed to get hold of a 160Tdi original map, so I am now verifying what changes were made.

Original ASZ File: http://www.filedropper.com/seatibiza19t ... 0891363556
160 TDi File: http://www.filedropper.com/ibizacupra_1
New ibiza file, with cupra160 guidence: http://www.filedropper.com/ibizav4
(Sorry, I can't seem to upload files to the forum)

On the new file, i have now only upped the values a couple of decemils, and advanced the duration 1 degree.

I havent mentioned before, but the only mods i have currently on my ibiza is a 60mm straight thru exhaust with Cupra backbox and a 80mm Cupra air intake.

Cheers for all the help :mrgreen:

Getting pretty close to something I might be comfortable with. My only immediate issues are that the single value boost limit is a little too close to the boost limit map, if the car has a little boost spike, you might find it going into limp home mode and storing an overboost fault code. I dont think I would raise it much, maybe 50mb? I think I would set the target boost and boost limit map just a tiny bit lower? I'm still a relative newbie but even so called 180bhp maps don't seem to need quite as much boost. Once running, drive it in varying styles of driving and look for smoke, if it smokes too much consider reducing the torque limiter then smoke limit maps a very small amount, if no smoke at all then maybe increase them a small bit. Take not at would sort of RPM and throttle opening the cat smokes at and try knocking single digits off the value around these areas.
Some of the more experienced could possibly off more from this juncture..... :D
