To end this topic from my side, the cause were the faulty injectors. Thank you for directing me into the right direction!

2000ccs now installed. Is it possible to insert new dead times and somehow calculate and adjust main fuel values and achieve same afr as with previous injectors? Like just switching over to different size injectors

Thank you! Much appreciated!

So this is what warm idle looks like, rough, i dont get why is it so unstable, and the fan kicking in is pretty rough also. Without changing anything, the warm idle afr is a lot leaner than cold idle. You suggest i should try different injectors? Thank you warm idle2022.llg

Thank you for looking into it. Lambda only gets close to target when the engine is properly warm. I will check vacuum with warm engine to compare. Under driving conditions the injectors have always worked well. I might then chenge them to 2000cc ones, these are ev14 also tho.

heres a cold start log 2022.llg

thanks adam. i will look into it and let you know. i had the injectors flow tested last year for the same reason but ofcourse that wont show the temperature difference

Hi, back in action after a long break. we have done a rough tune that still needs shaving, but still, to my knowledge i do not have any enrichment activated at any times and i am still running too rich warmup. i also took about 40% off from the crank fuel table to start it properly, while having ethanol, i should add fuel. i run e85 which should require a lot more fuel than gasoline, i have no enrichment and still too rich. while warmed up, i have decent afr, if you look at the fuel table you see how much i have taken the fuel off to get a decent reading, actually even needs more to be taken off. but it starts way rich. shouldnt it be the other way if i dont have any enrichment? it should be too lean. but its the other way around. could the idle valve have some settings off? i have updated the injector dead times also i had the same thing with my last ecu so its partly the reason i moved over to link. thank you rough.pclr

fiveo bosch ev14 propably. i have the sheet in my hand. 12.5 ohms and dead time 0.875ms at 14 volts. edit, theres a whole table for dead times where should i put that information? edit: oh yea i figured it out now. the dead time table. but what about the master fuel 8ms?

fuel map is not tuned, im only working with idle right now. thats the confusing part, injectors, my previous ecu i chose the correct injectors from a list, but in link there is no injectors choice. i only changed master fuel to 8 ms so i would not need fuel trim i have 1600cc top feed injectors

can i steal this thread since i have a similar issue. i think i have all my warmup richments off. im in a process of copying data over from previous ecu and have not been road tuning it yet, trying to make it idle and warm up properly or at least understand how it works on link. i had too rich warmup with my previous ecu also, so im not sure whats going on, thats one reason why i switched to link. on previous ecu i restricted injectors during warmup to make afr reasonable. this is my first logging attempt, is it any good? could this pinpoint too rich warmup issue? warmuprich.llg wideband-.pclr

thank you. i will test that! yes WBlin- is connected to sensor ground. this worked fine in previous ecu previous ecu settings read: Linear, Span 2500, Offset 1000

for some reason, the reading compared to my afr gauge that is hooked straight to it is pretty different. the closest i get is with 0-5v autronic sensor, not exactly ideal but pretty close

great! thank you!

hi. im coming from a differend brand standalone ecu and i am relatively new to link. i have a subaru pnp g4+ and i am trying to get wideband information to ecu directly. everything works and car idles just would make things a lot easyer to get the wideband info to the software. i have a tech edge wideband https://www.wbo2.com/2j/default.htm i have the the ground grounded to sensor ground and signal wire on AN Volt 4 (B17) what should i choose from the input list and how should i set it up properly, also what gauge should i choose from the new view list to get a proper afr wideband gauge? thank you
