Guys, not many succeeded with MAF to MAP hand conversions. There is a ready and reliable MAF emulator 3 in one Ukrainian shop for 350 USD which has a huge amount of functions and can replace ANY 5Volts MAFs. It works with original or aftermarket MAP. MAF can be completely deleted and you have limitl...

Thanks Olafu!

Based on my “knowledge” it is better to ask someone (expert) to edit existing XDF and add a few functions

Hi, I’m using TunerPro soft for Bosch DME 402
Existing XDF is very poor, compared to others
I would like to change/tweak parameters in some other areas like FUEL AT HOT/COLD START UP, LAMBDA ON/OFF
Please, teach/help me to create an extra XDF tables for mentioned above
Thanks!

Found out the correct injector constant without “GURU” help here

Another problem, when engine is hot, I have to run starter for 7-8 seconds in order to start the engine

Cold start is OK

Where to look?

Hello Need help here I ran my engine with 250 cm injectors before and it was not enough after 4K RPM and 0,9 boost Injector constant was 54909 I have changed to 440 cm green BOSCH injectors and cannot start the engine I have tried different constants from 54800 to 53000 but it doesn’t start I can he...

Size of injectors?
Stock MAF?

Can someone PLEASE edit or change existing XDF for 402 DME in order to have an option/flag to disable oxygen sensor?

Important correction - I had lambda terminal removed
If lambda is connected, DME will correct the AFR no matter what you’ve done with map

https://www.instagram.com/tv/CHfzNOXJ8 ... q5u3woed07
I was able to change the idle AFR (reach/lean) by selecting the whole IDLE FUEL MAP and increasing/decreasing all values
Not sure if the rest of maps would work the same way, didn’t test on the road yet

Yes I have green EMULATING text on the bottom left
When I change idle fuel map, for example, I save changes, message UPLOAD SUCCESSFULL, and emulator is beeping

I found something on page 5 about lambda
We should put 0 to four or five lambda addresses, then ECU will ignore lambda and refer to fuel maps

UPDATE: I can find 2 HEX addresses and only, I can’t see other three in my bin, WTF?

I’m new to the using Tuner Pro soft let along EEPROM emulator for online tuning of ECU Yet, I rather understand what exactly I do need from my turbocharged M50B25 non vanos The problem is any changes I do in fuel/ignition maps, don’t change engine performance and AFR What those 128 numbers mean in t...

this is the first step as i understand make the " table of table" in a list like thisStep 1.jpg then i have the WOT fueling map start at 0x7234 = "8B 8A" , but i cant find it in this list ( i searched for 7234 , 8B8A, 3472, 34F2 ) or what should i found ? I use the same Tuner PR...

Hi bro
I have the same need of disabling lambda on 402 dme
I can’t change any idle and POT values online - have a feeling that lambda overrides my input

I mean I have MOTRONIC ONLINE eeprom emulator - Motronic RTP
