Title: Stg 3 asp ko4 switching from deka to ev-14
Post by: Jprechel on February 27, 2012, 08:18:06 AM

hi all, I have a 01 s4 stage 3 ko4 with ots asp kit. It was installed bout 35,000 miles ago and it's really running like poop. I tested everything and found the deka 60lb injectors to be the problem. Running 4bar fpr. Misfires till 2800 rpm then smooths out a bit. My question is what do I need to do to switch to ev-14 injectors?  Thanks john

have you considered flashing the Nefmoto Stage 3 base tune?  do you have a second ecu or have the capability to read off your current .bin file?
i doubt you need new injectors tbh, but yemv, ya never know.

So it was fine, then went bad later?

How do you know it is the injectors?

I just bought the car this way. On vagcom it misfires in double digits pretty quick on cyl 1,3,4. The other ones may get 0-2 before it resets. Tested everything found nothing till I switched around the injectors. Then the misfires followed those injectors.

Hi.  Former ASP customer.  Those tunes are junk.

Start from scratch.  Tony's base stage 3 tune will work well for you as a starting point.

You can create a backup of the ECU using Galletto in boot mode, then flash over it with Tony's tune.  You can flash back using NefMoto if you want to switch back.

I'm not new to audi's or s4's. I own a 2000 stg 2 also. I have replaced the 2000 motor and everything in between. :) But I am new to tuning an ecu and flashing one as well. I'm open to playing around with it a bit cause otherwise vast quoted $900-1200 for a tune. Asp wanted $600 for the same stg 3 tune I have only with ev-14's. Seemed a bit much for what I consider a revision. Tell me if I'm wrong there. And no I don't have an extra ecu.

I have been looking at the nefmoto stg 3 base tune, any body running it wanna chime in? How well did it work out of the box, how much playing around with it did u need to do and what did you need to change. Thanks

I'm in Atlanta.

I came from an ots asp file. PM me - maybe I can help.

My file is done for now. I may tweak once I run with over 120* intake temps.

Yes, that's ludicrous pricing.
