Seat Altea 1.9 tdi 105cv bxe engine (2 tuned maps)

Postby javi174 » Mon Jul 09, 2018 8:56 pm

Hello, I just got two maps (attached) for stock bxe engine while waiting to fit arl injectors and turbo.

I have some questions about this ecu as I am trying to figure how it works. First of all thanks for your attention, if someone could please tell me where to find information about when each different map comes into play (drivers whish maps, hysteresis, egr, lambda, n75, boost limited or full..) or where to find a guide for the ecu.

I have found some "weird" things (from my little understanding) on those tunes, one of them has decalibrated the duration map hugely for instance, instead of re-escalate it so as the "nm to iq" map.

What is the difference in limiting the iq through lambda map or smoke limiter map? It should be a reason for lambda map, but is it not redundant given the smoke limiter map?

Sorry for the newbie questions, I am trying to learn but I dont know where to find info as a base for these ecu. I have read all the guides I have found, but maybe I have missed to find others..

Thanks for your attention
