RobPhoboS Posted January 31 Report Share Posted January 31 Hey all, I'm just trying to adjust a few small things on my tune, initially this warm up phase seems to be too rich 0.7-0.8 on lambda 2 (I can't remember right now why I'm not using both sensors). Would you just pull more out of the warm up enrichment table - or should I be looking at something else ? Lastly, if anything else looks funky in the tune, please do say as it's been ages since I've gone over it (a lot going on over here unfortunately). Appreciate any pointers WarmUp_Rich_v001.pclr Log 2024-01-31 10_30_03 am.zip Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 31 Report Share Posted January 31 Lambda 1 is showing error 5 which I havent seen before, I suspect it will be the sensor. Try swapping the sensors to confirm. Im not sure if it is only "warm up" that is excessively rich as even when warm CLL is pulling 15% fuel out on bank 2 to reach target. I would fix lambda 1 to confirm both sides are behaving the same before making any adjustments. I suspect it is probably more the values in the charge temp approximation are too small around idle which means you arent getting enough compensation as IAT changes but adjusting that now would mean the fuel table would need to be adjusted also.

RobPhoboS Posted January 31 Author Report Share Posted January 31 Many thanks again Adam. I think it was something to do with the tuning, that both sensors on was causing an issue (will contact tuner, doubt he'll remember though). Yes I do recall that it was still correcting too, which doesn't seem quite right either. Appreciate your response, it makes sense and will give me some more pointed questions to ask.

RobPhoboS Posted April 4 Author Report Share Posted April 4 Very small update on this. I checked the wiring, and it ended up being the bank 1 sensor dead. I've replaced it, thankfully I found the exact same Bosch sensor as it turns out they have changed the connectors. So he must have told me there was a problem with it and that it was only tuned with data from bank 2. Quite a long time ago now so I cannot recall what was said at the time. I've kept the sensor but I presume each sensor is calibrated, so you wouldn't just be able to cut the old connector off and switch out the new one? I did email them 2 months ago but still no response, so I'm going to my local place to get the map sorted out when I can. I did a short test log only at idle to make sure it worked and yeah both banks are correcting differently (bank 1 seems to correct half the amount).

Error 5 - must just be dead sensor (which is was, and is replaced now). Fundamentally, it's just correcting far too much in CLL, and I think it just needs to be redone as I'm not really happy with it. Quote Link to comment Share on other sites More sharing options...
AbbeyMS Posted April 8 Report Share Posted April 8 using a pair of can lambda's? You can order the correct lambda sensors for the Link Can lambda for replacemnts RobPhoboS 1 Quote Link to comment Share on other sites More sharing options...
