flashed tonys base tune onto my box, cel and epc blink very fast when the key is turned and the engine turns over but no start. ? what would cause the flashing cel and epc ?

Sounds like a immo problem. Does the file that you flashed match the original ECU file of yours? i.e software version, ecu number?

i dont understand what should be matching up can you explain it more ? the ecu case says its an a box but its been tuned before and i have no idea what was used.

Ok well firstly did you back up your original file? If so flash it back and make sure you car starts ok.
I am not familiar with Tonys tune but post your original file and im sure one of the top dogs on here will see if its a match.
ECU's have numbers like for example, a Golf AUM engine might have a ECU number of 06A906018HJ and a Seat Cupra may have 06A906018MJ. Some can be cross flashed (not recommended) and work while it can cause your car not to start.
This may not be your case and i am a novice user but try what I said and see if it works.
Also they have different software versions even though same ECU number.

i could not read the original file because of the  tuners lock

the code on the ecu case is 8D0 907 551 A

Does your hardware match? Same MAF, injectors, etc?

you have to bootmode flash the file on.... you are changing base software number always bootmode!!! M box does not have immo.... if you flash mbox to ecu with immo it will bypass it. even tho the ecu is not bricked you still need to bootmode flash it....
ps
buy mpps from ebay... has bootmode recovey.... at the rate your going it wouldnt be bad to have and READ MORE!!!!!!!!!!

ok flashed same bin with galletto in boot mode will try to start the car tomorrow, thanks for the help !  ;D

car still wont start and periodically there's a clicking behind the dash and my throttle body keeps trying to cycle ? what am i missing here ? 

Does the battery have enough juice? Sometimes things can get overlooked. If not I'm not sure. ???

Are you writing half a file, as in the wrong memory layout?

battery is on a charger, i have to correct memory layout for a b5 s4, when i boot flashed i noticed the chip wasn't
 factory and had been soldered in. could that be whats causing this mess ?

Definitely. Have you been able to recover it at all? Chances are you need to desolder it and put a stock chip in.

Bricked

here is the factory chip for your ecu http://www.ebay.com/itm/New-AM29F800BB-70SC-AM29F800BB-/281043841364?pt=LH_DefaultDomain_0&hash=item416f84b154 or if you want and providing your in the same country that im in I have 2 s4 ecus Abox and Hbox. If you want to mail me yours I can mail you a factory replacement.

i was able to source an 2001 a6 2.7 MT box for 70 bucks should i buy it ?..... i dont have the steadiest hands and proper soldering equipment

70 bucks is fair!

If you want, I will fix your ecu. Just cover the chip (5 bucks) and shipping!

thanks for the help guys, i think im just going to buy the second ecu to get it here quick and have a spare . i need to get this thing running. the  engineering college i go to has the proper soldering tools for my use  getting a new chip soldered in the original ecu shouldn't be a problem now that i think about it.

Very good! Just make sure to get one rated for the same speed (or faster).

Stock is 29F800BB-70SE, I use 29F800BB-70SD without a problem. Do not use 29F800BB-90S!

My chip is a am29f800bb-120sc  any ideas how i could fix the problems im having with this chip ?

Hey everyone... I'm having a very similar problem. I installed EV14's today and I have been tweaking the tune for a good part of the day. On my last flash, everything appeared to flash normally as it always has but when I started my car it jumped to 2200 rpms then almost died and bounced again and I killed it. The EPC and check engine where both flashing the entire time it was on. I started it one more time to see if it was bricked, to my limited knowledge it wouldn't start again once it was bricked. But it started. So I tried to flash my last known good file on the car, but now NEF connects but when i try to flash it says "Disconnected because no response was received from Tester Present Image"     I thankfully got a hold of ddillenger and he told me to disconnect the battery and keep trying as long as it started it wasn't bricked. I waited for about an hour with the battery disconnected, when I plugged it back in and turned the key to on, the TB began to cycle. It connected to nef first try, but same message again about 5 seconds later. VCDS will not connect to the ECU, but will to every other controller. I kept trying at different speeds etc.. with nothing. So I started it, it will stay alive if you keep your foot in it, but bounces and both EPC and check engine light flash. I only ran it for 5-7 seconds and killed it, and started it again one more time and it always seems to start. From everything I've read over the last two hours, it sounds to me like it's bricked. But I still have a lot to learn so I wanted to get everyone's opinion. Thank you in advance for your help!!!!

Yep. Bootmode it.

Right on, thank you for the reply!  I will be purchasing another ECU tomorrow from ddillenger as well as attempting to bootmode my current one. 

Just be careful not to accidentally touch any other pins :P

A test light with a fine point works well, or a tinned wire.

Thanks for the idea of the test light ! worked great!  Sadly I attempted a few times today to get it into bootmode and I'm getting nothing.  ???  One thing I did notice, when I ground pin 24 the throttle body stops cycling, until I attempt to flash. If I keep pin 24 grounded as I read some have done and try to flash, it starts the flash process but after "erasing...ok" "writing error" and thats as far as I can get it. Any thoughts?

I don't know of anybody who has done this.

Pin 24 is an actual data or address line (forget which) which is sampled by the ECU during bootstrapping *BEFORE THE FLASH IS ACCESSED*

I will have to find the thread I read it in, but he stated he grounded the pin until the read/write started if  I remember correct. Either way I haven't spent very much time going over bootmode stuff in the first place so I feel like a complete dumbass while trying to figure this out, plus I should've been more prepared for this situation...  :'( :-[ >:(       But now Im just going to take a step back and start re reading.

easy inside car... disconnect battery remove and inspect ecu find boot pin 24 on the 800bb chip. with ecu still disassembled plug in only the larger of the 2 plugs from the car to the ecu. with the power still disconnected put your key in the ignition and turn to the run position. use some fine gauge wire 20- 18 awg, find a good ground spot on the block, firewall etc to ground that wire... put it behind a bolt twist it around something so it has good connection... ok now that the battery is disconnected, key is in the run position, and ecu is hooked up... this is where it gits critical.. best is to have a buddy help you for the next few steps... touch pin 24 on the 800bb chip with the wire that you grounded to the engine / firewall... when your comfortable and know you have good connection (this is where a friend comes in handy) put your ground cable back onto the battery.... continue to hold the wire on pin 24 for about 5 seconds..... have your computer set up and ready to go with mpps or galletto and the file you are ready to write after your 5 seconds click write file and your computer will start a blind write to the ecu....

few side notes... use some solder and tin the end of the wire like dd said. this will help reduce the chance of hitting other pins... could use a resistor to reduce the chance of damage if other pins where hit... You might have to try more then once to get the sequence down too... once you do it its forever easy after that... just take your time and do it... If you have any questions or further troubles shoot me a pm and ill help you out...

Don`t forget to get out fuse from dashboard before getting into boot mode on the car. I`ve tried more than 3 hours with no success. After removing dashboard fuse worked like a charm.

Thank you for the advice guys! I did try two more times, but no success. Although I think I am getting it into bootmode, it starts writing, says SEED OK, then erasing...ok then start writting    followed by writting error.   I am leaving on spring break tomorrow and the ECU will be on it's way to ddillenger. I am going to build a bench harness and try to stock up a few ECU's to practice on etc... as well as back ups. Again, thank you guys for the info!!!

I was under the impression that was only required for immo cars?   Either way, which fuse are you talking about? as I have an 01 allroad I will be flashing one day soon.

It seems that the more I do the more I want to pull ecus out to flash them... I had a 2004 mk4 auto that I did a read over obd2 and had a error that I had to pull the ecu to rewrite to clear. before that I had numerous me7.1's I had issues writing to inside the car... for the amount of time it takes I find its well worth it...jmo but it works for me... I made a bench set up with a old 650 watt atx power supply, a ecu plug I cut off a junk car and a obd2 and to obd1 adaptor for my mpps cable / vagcom
