Hey everyone. For a long time i wanted to code out the SAP on my 325ci with ms43.well ive used inpa ncs expert and winkFP before but this is the 1st time i use tuner pro and JMgarage... so i was reading and watching videos about how to tune the ms43 and all i can found is to download the 512KB which delete the EWS.so the question is can i delete the sap without the 512kb flash?

So i am somewhat new here, i have done the usual mods, intake, headers, exhaust etc and i was wanting to figure out how to use ignition cut launch control. I am somewhat familiar with tunerpro as i have done exhaust pop and multiple other changes. Never was able to get LC working correctly.

All bits that you need are in the 64kb calibrations binary.

Ignition cut hasn't been Implemented yet unfortunately, I know a tuner who has done it but daniel/sda have not released theirs yet!

Have a look on the wiki, it tells you what value to change under SAP delete, do a partial read with ms4x flasher then apply the values and flash back

You shouldn't need to touch boot mode at all for this unless you want to make a full ready back up

Hello everyone from Estonia. I am quite new to tuning, have several questions.
1. I want to add pop mode and lumpy idle mod to my m54b25 with original catalyst. Can I use fuel cut with original catalyst? As I understood from ms4x.net only ignition cut will toast catalyst, so popcorn and "race" camshafts is OK for them, isn't it?
2. I flashed ms43 512kb without launch control, but i have launch control settings in my 64kb file. But it does not work. So i need to flash 512kb LC file?

nothing that dump unburnt fuel to the exhaust is good for the catalyst.

1. Any sort of pops/crackle will harm the cat, the intensity will decide on how much harm it will do, however they will still last quite a while with just over run unless you are dumping a lot of fuel and retarding the timing a lot, also I don't think 'ghost cam' will have any effect on the cats.

2. Yes launch control must be enabled and setup with the 512kb flash

Interesting. Well, you'll need the matching XDF. This .bin makes the appropriate code changes, but without an XDF, you'll never be able to see or make any adjustments.

Forgot to reply to this. It ended up being that the previous "tuner" had disabled the MAF DTC .
