[quote="jonixins"
If your tuner is clever enough, you can use 074906021XX MSA15 sw in 028906021XX MSA15 ecu hardware both will work. Or you can come to me (LV) and I'll do sw change for you. Also I can sell you already modified ecu with failsafe sw.

For wiring you just need to change ECU plugs + 1-2 spare wires. If you go MAFless and delete EGR it will be easy - 2hr comparing and 1-2h soldering.[/quote]


Thanks for you help. Wiring for me is not the problem and ecu fleshing, repairing... I do it every day. I see what this ecu's is the same hardware and i can put whatever software to this ecu. 074 xxx xxx xx is vans and 028 xxx xxx xx is passagers cars. One thins is make personal software tune i contact with you. Thanks alllot and i going do wiring job.

my ecu is: 028 906 021 CE
I thinik make 074906021 M (111kw,151PS) need search for not modifed original soft.

By the way,

Audi is now building a newer generation of the 01E-gearbox.
The new generation is called 0A3 which is more robust than 01E.

Look at SSP 325 (SSP means "Self Study Program"):

And it's very cheap in Ebay (under 200 Euros):

But will it bolt to an I5?

[lagas]

I think yes, because V6 engine. And i known I5, v6, v8 have the same gearbox flange.

If your car will run standard injectors you don't need anything more than default turbo. It runs great till ~1.6bar. If you use K16 turbo (direct replacement) from audi 100 tdi, you can get ~1.7-1.8bar. Only problem will be IAT.

no, the K16 from AAT never reaches over 1,5 bar at maximum, same with the K14.
The K16 has only more air-flow, so it's better for higher rpm...

It reaches and it can reach even 2.0bar but it isn't safe anymore. Do not use standard ecu, n75 or 1.5bar map sensor.

[steftn]

I don't think so.

My K14-Wastgate is completely closed at all times and I never reach over about 1,5 bar....
I have selfmade mechanical TDI-pump...

[jonixins]

use static VNT or just connect WG and pressure pipe or your turbo wg has a defect.
I hope you are not meaning diagnostic values and standard MAP sensor.

CE ecu won't work. There is no 5cyl sw for this type of MSA15. Most of VW and Seat will do the job.

074906021M is the right sw.

Here is the characteristic diagram from K14:

K14 only reaches about 1,5 bar (excess pressure)
= about 2,5 bar (absolute pressure)

:( , i find it:

074 906 021 M
074 906 021 A
074 906 021 T
074 906 021 S

028 906 021 HH
028 906 021 GT
028 906 021 HB
028 906 021 HC
028 906 021 JJ
028 906 021 JK

now need search new ecu :/, maybe search newer one, EDC15VM+ (074 906 018 AN) then i can flash using only obd.

Then also you can see it's only part of the diagram.

028 906 021 HC
028 906 021 JJ
028 906 021 JK

And even more.

now need search new ecu :/, maybe search newer one, EDC15VM+ (074 906 021 AN) then i can flash using only obd.

I do not have this software and I haven't seen it, but I'm very sure you won't be able to flash 021 ecu (MSA15) via OBD.
You can use EDC15 ecu for newer softwares, but have to change accelerator potentiometer and i suspect tacho issues.

[lagas]

my mistake, is 074 906 018 AN, LT35 2.5TDI

MSA15 via OBD only read, but if change flash'es to erasable then maybe, i not try it.

Thanks

[jonixins]

msa via obd is no way, ecu don't support this.

By the way,

Audi is now building a newer generation of the 01E-gearbox.
The new generation is called 0A3 which is more robust than 01E.

This gearbox is very good, I agree.
There are two issues with older cars:
1) no speed sensor
2) axle-shaft connection
are there solutions?

This was fun!
Got the best time of the day.. woohoo!

Thanks to Marcel and Matthew for organizing this!

What is the world coming to? TDI powerslides. Fastest laps. Great fuel economy.

My 4 year old was having fun in the passanger seat reading his "star wars" books...

[1wheelpeel]

I know what you mean. I took my kids to monster jam and they were bored. Really? 1500hp and straight pipes doesn't do anything for you??? :?

But, if I gave them a monster truck video game they could play it for hours... :slap:

[chaloux]

Hahaha... awesome pic and hilarious about the kids John... makes me wonder what I'm in for.

Was Martin holding the stop watch when the urs4 guys were running? Did anyone check his car for studded tires? :wink:

Martin,

What a great day!!!!

Thanks for letting me drive the b4, what a blast.

It almost had too much traction, a really fun day with a great group of people.

Hopefully I'll have my 90 there for some side way fun next weekend.

Cheers,

Craig

"why's the snow black?" hahaha

hope to make it out on the 10th!

The new summer look with Competition/Cabrio 16" wheels..

[mrmotorhead13]

Man I love those wheels Martin, I need to find some for my B3! Actually this whole project overflows with awesome...

[T-Rex]

Wheels look great. I love the OEMish look of the car.

Andrew is refinishing a set of summer rims for me. Cant wait to take winter shoes off.

Do you still need those door hinges? I will be at my storage this week, I could get them for you.
