The 1st link appears to be broken...
Iv'e looked up some of the links on the 2nd one. Iv'e been there before but I'll do some digging.
Thx for the help !
Edit : sadly, this documentation cover the US version, and my car is Euro spec...
By example : the literature you've linked says the TZ28H disappeared in 85 and came with the B19A, B23A and B230A... But my car is (was) equipped with it
My car is an 88, with K Jet (without lambda sond, yes, ik it sounds crazy, we only got LH in some GLTs here, my car doesn't have any emission thingy)
Hence why I am struggling to find the right curve... I think I'll have to try and see. I only put 98 in my car so I don't fear knock much.
