Identify rs2 / s2 chips

[vidar skotheim]

I have some chips that was told was for s2 ecu and s2 maf and rs2 injectors , in the vag com text it says
8A0 907 551 B and 2.2R5 Motor.RHV RS2 D03 .

Basic program should be RS2 but whats real inside you have to read them out...

Fit them and VAG com the ECU to see what the description is.

I am not so into read out program , buth tink it is strange if these are for s2 ecu / maf ..

[vidar skotheim]

I allready wrote what comes up with vag com ..

must not be strage... MAF is no point because 99% equal...

if they are for S2 ECU, the load/fuel calculation must be modified in data...

I can read them out for you if you want...

There is big difference in load with s2 ore rs2 maf , also the wide band say big difference in the maf .. so that could not be correct .
if i put a s2 maf on a rs2 ecu the wide band dorps from say 13.5 to 11.5

[vidar skotheim]

load with s2 maf on the rs2 is close to 50% , with rs2 maf arround 30%

[blackS2]

load with s2 maf on the rs2 is close to 50% , with rs2 maf arround 30%

THIS sounds strange to me

[vidar skotheim]

Tested lot og different ones . Lot of difference ,as it should . If not the rs2 would not be abel to follow on more power .

I thought it was accepted that electronically the S2 MAF and RS2 were the same. They do loose calibration over time though so an older MAF will appear different to a new one. This was covered partly here:

Lots of info here too:

so I do

[vidar skotheim]

Well . I have tested many different ones and they al give the same result ,also after driving a few days .. when use a s2 on rs2 it gives a lot to much on partly throtel . What is writen on net i dont care about . My wide band i thrust more ..

[blackS2]

What is writen on net i dont care about ..

so why do you ask somebody here on the internet

sorry

[vidar skotheim]

I asking about identyfing chips , not about using different MAF .
