My car is E92 335i N54 DCT 2008 (EUR version not 335is)
I can’t decide which version to use between IJE0S or INA0S.
What’s the recommended software version for tuning my car?

Z4 35i & 335i
I think the latest ROM from BMW was INA0S for the 335i DCT but they reverted it back down to ILA0S because there was a bug in the INA0S CAL that prevented the readiness monitors to set.

MHD will select IJE0S as the latest stock file because nobody bothered to make an XDF for ILA0S.

So not a straight forward response. But for the Z4 they were all updated to INA0S because the engine stayed in production longer. The 335i with the N54 stopped production in 2010 i think whereas the Z4 ran until 2016.

i use INAOS in a E93 2010 with the famous M3 GWS swap, with the complete drivelogic and GTS custom firmware.

the best MHD OTS maps for DCT is INAOS firmware.

For IJEOS, V9 and V10 maps have torque send to "big" and no throtle lag...resulting in cluth punct.
V7 maps had smoth gear changes and stop to run transicion.

INAOS OTS Maps are all ok for the DCT, no issues.

Oh, thank you very much! I also plan to do the M3 GWS swap, and I will use INAOS as you recommended.
