(**is this fuel tuning process for tuning stg 3 cars w/ upgraded MAFs?? If tuning a stg. 1-2+ car, what fueling maps, if any, would need to changed??? sry, this was the only way i could figure out how to ask you a question)

Technically, no, it isn't needed for 1-2+, but if you are running a bunch of boost on pump gas, a bit of extra fuel via LAMFA or KFLDBTS isn't a bad idea. - Nyet 17:58, 30 August 2009 (PDT)

Also, do you think you can add the exact process for flashing (read/write) the ECU. Do you have to take out fuses? Do you have to use a battery charger to make the voltage stable? Do you have to put it in boot mode? NorCalS4 21:18, 30 August 2009 (PDT)

No, no fuses necessary. The most important thing is making sure the voltage is ok... bench flashing is always the safest - Nyet 22:05, 30 August 2009 (PDT)

also, one this part "FLKDHBN - maximum requested pressure ratio " , isnt FLKDHBN suppose to be KFLDHBN?? - NorCalS4 21:42, 30 August 2009 (PDT)

uh yea. i guess is should fix that heh - Nyet 22:05, 30 August 2009 (PDT)

Anyways can you post the steps to flashing either here or on the tuning page? Also, is there a way to flash in teh car, though the OBD port? If so, would you like to explain that to me? Also, piggie gave me an invite to the "other" forum. I have been looking around and cant find much on ME7.1 tuning. got any links I should follow? - NorCalS4 10:31, 31 August 2009 (PDT)

I don't really know the technical details, if that's what you are asking.. I only know to point and drool the software UI. Its pretty straightforwards. For the non-boot mode ones, you really just need a stable 12V source. Radio off, A/C off, if you are doing it through the OBD port. For the boot-mode ones, you have to hold the boot pin to ground while you power up the ECU (easiest to do on a bench) for a second or so. As far as that forum goes, its more for discussion of details. Feel free to email me if you have any other questions. As you can see, discussing things here can be cumbersome - Nyet 11:19, 31 August 2009 (PDT)

okay. to me its ok discussin it here, if its okay with you. Ill be on the other forum more and will look around more. What method do you use for flashing? Do you road or dyno tune? I will be road tuning and i want to use the method that would be the most convenient one. - NorCalS4 11:45, 31 August 2009 (PDT)

I use the Galletto (bootmode) on the bench, primarily. I can do it in the car in a pinch, through the OBDII but i carry the bench harness with me with a cig lighter adapter. Run the laptop off of battery, turn everything in the car off, and use the harness. I log WOT using mostly 3rd gear road pulls. I do part throttle fueling tuning on the road using varying gears and uphill/downhill grades. Would be nice to have dyno time but i can't justify the expense - Nyet 13:26, 1 September 2009 (PDT)

Okay. I would like to do it without going into boot mode, if possible. I have galletto cable and a kwp2000+ inferface. What cable & program should I use for flashing though the OBD port without puttin the ECU in boot mode? - NorCalS4 14:05, 1 September 2009 (PDT)

The software is on the Tuning page near the top. I just bought a cheap kwp2000+ cable on ebay. - Nyet 14:54, 2 September 2009 (PDT)

I also got a cheap KWP2000+ off of ebay. So can I use my KWP2000+ cable and KWP2000 ME7 software to flash though the ECU without putting the ECU in boot mode??

It should work. Always make sure your power source is stable though. And always have a spare ECU on hand if you are doing flashes out on the road. You don't want to get stranded if you brick your ECU - Nyet 12:39, 6 September 2009 (PDT)
