Lean WB Driving

[stl_ty]

Running Code59 and found base bin close to build then ran first autotune ok then after loading new bin into ostrich it would run ok, it ran ok at temp for a while then started to get very lean and popping/backfiring. if i would reload the base bin back into it would drive ok again for a while. What to do? i could use a better base bin maybe. also have problems getting the idle near 14.7:1 by changing base pluse constant.

Sounds like you just need to start doing some logging, and adjusting the f29x. Which base BIN did you use?

f28 should just be used at idle to get it where it will run... use f29x after that. You also need to make sure the correct wideband flags are checked. You are running a 3bar map and wideband, correct?

Yeah i know to use f29x for tuning after and i did only use f28 for idle but f28 would not move very much with changing the numbers then i t would just go lean die so i just let it idle a little rich i think like 14:1

yes i have a aem wideband and 3bar map all hooked into my ecm and it is reading correct in my logs.

anyone got a code59 base bin for
