can lambda. 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.

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).

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.

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

So far it seemed to be a mix of IBP, and the idle speed lockout, my one was set to 1.2mph for some reason which seems a bit too low. Will test some more in the coming days.

Cheers for that, yeah I went back through an old set up I did, and checked against this one last night. I think it was just Idle Base Position largely, it's not quite there yet but I'll test it again over the weekend.

Hey guys, as it's been many, many months since I've delved into the ECU I cannot remember what on earth I might need to adjust slightly to get my idle to come back down to normal when coming to a stop (ie traffic lights). The idle is usually around 800rpm but it'll be around 1200ish unless I prod the throttle lightly, then it'll come back to where it should be. It doesn't happen 100% of the time but more than not, if that makes sense! This is for my DE 350z.

Fantastic, thank you for that Adam. It certainly pushes me in one direction for now, whilst on the G4+ !

I've edited the above topic to be a bit more concise with my questions, hopefully it makes more sense if anyone is able to chip in.

Probably since 2014 Cheers for the PM and replies guys

Hey Adam, I have the Vipec i88 350z p&p (just running G4+ software).

@Adamw Possible to also PM me the details for the issue with VDC and SLIP light always on? Many thanks !

Well, got the Z mapped on the G4+ finally, sooo much better (especially being able to address any small issues myself now), however it's not quite making the power I'd hoped for. Nothing bad, same as my previous essentially but of course it's a project car so in the future, I'll potentially look to improving the HP. So I'm left with a few options, trying to figure out what will work with the G4+: Install the HR upper/lower intake plenum - but these are dual throttle bodies - is this possible on the G4+ and my ecu? (I know Link sell an ethrottle controller but not sure if that would help?) Jenvey ITB's - but once again, not sure if that's possible to accomplish with the G4+? I presume the 82mm TB kit (ETB82) work with the G4+ ?

Thank you for taking time to have a peak at it, I'm really enjoying the platform and getting a glimpse at this stuff.

This is the first drive, there are a couple of seemingly high AFR spikes but not sure what's happening there (I was off the gas iirc and coming to junctions): I was really happy how this initially felt, no stalling !
