Styp Posted April 28, 2020 Report Share Posted April 28, 2020 Hey, I need some input to maybe accelerate the debugging of my map. My 2jz is bogging under load in low rpms (up to 2500rpm), i pulled ignition back a little didn't change a thing. I know very well, that the car runs overly rich in this log, but 0.7 - 0.8 should be very well ignitable with R35 coils, as this is not so uncommon on WOT high boost applications. Working on the Charge Temp Approximation anyway, therefore it is on the rich side of things. Any ideas? Cheers Styp Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 28, 2020 Report Share Posted April 28, 2020 You need to post the actual log and tune as there is very little info available from a single screenshot. Having said that I think you answered your own question, any engine is going to feel like a turd with 0.7 or 0.8 lambda at cruise, this is where the tuning term "fat" comes from. s it VVT? What are the cams doing? Have you confirmed base timing and no timing drift with RPM? Quote Link to comment Share on other sites More sharing options...
Styp Posted April 28, 2020 Author Report Share Posted April 28, 2020 Hi Adam, Once it is resolved, I will post an update in the thread. I know it is ridiculously fat - very well aware of that. VVT is fixed for the moment, didn't look into that. Base timing should be set, will confirm - timing drift, is a good input - will check later! If you want to have a look into it: ... Log and Map is attached. Thanks & Cheers! P.s. Guys, just don't use this map! Quote Link to comment Share on other sites More sharing options...
Styp Posted April 29, 2020 Author Report Share Posted April 29, 2020 Nevermind, acceleration enrichment was all over the place - didn't see that one... Quote Link to comment Share on other sites More sharing options...
