I was reading previous posts about the LexusPro Full ECU and the pros of the ecu seems pretty promising but there are some cons that I'm not sure of yet. Anyone want to comment on this ECU? Also, I was reading that the ECU will end up retarding the timing and fuel after awhile so would that mean I would lose all my gains and will have to reset the ECU all the time or will it just not be as aggressive as when it was first calibated?

i think the full ecu is only for sc's w/ nitrous, and the $900 one (or whatever the price is) is for those w/o spray. jus fyi

I had my last car chipped, but it was a turbo, and raising the boost makes a significant difference.. not sure how a V8 n/a car would be chipped, is lexuspros the only company doing this?

I'd be game for a ecu upgrade, think it's safe to do with 140k on the speedo?

yea i know,i'm just saying that the full ecu is for sc's with nitrous, regular is for one's w/o

no, the nitrous upgrade is optional which you could add to any ecu, regular or full.. and all it is a switch for a second sets of maps for when you want to run nitrous..

i don't think the point i'm trying to get at is comin across. oh well, never mind

Oh I get what you mean now.. well SC400-V8 had the Full ECU so I'm thinking the advance timing is helpful so what even for NA..
