"MODDED STANDARD INJECTORS" <-- There's your problem, as said earlier. Seen this SO many times before, spray pattern is more important than most people think Yes I know the importance of it but that's why I'm afraid of that it might be that.. But I'm not really able to get a new set so I ...

Adjust latency around idle, k value from 3k+. As long as the car starts and drives fine, I would make minimal changes to get the afrs where desired.

Hmm, could try adjusting it a little.. But my k value is set at 21k something..
Is that too high?? Or are we talking about different values?

If the actual afr's on the higher load area of the fuel map are richer than the commanded afr's the k value is too large. I adjusted the k value 'til it was about right on idle but perhaps it's better to have a closer target AFR on high loads and then just change it on low load area until it seems ...

I was thinking about your problem, then I remember it was mentioned in FAQ under question 19 "higher flowing items will have less control resolution." That could be the problem if they are 880cc, as 800cc seems to be the limit for stock ECU. Although, one workshop has run 850cc injectors ...

At first I thought so too but the Greddy Profec B is very stable and except for when it suddenly wants to die the idle is stable too.. Runs real smooth but the AFR is still fluctuating...

have you triede to adjust the lantency ? I'm using modded standard injectors so the latency shouldn't be any problem.. I don't think there are any problem with the injectors either but of course I can't be sure.. my wideband is not that stable on idle.. depends on how you have installed it ? have y...

Thanks.. I've read all the documents many times =) And then many times again.. I'll try the new software though... I switched 02 off first when I adjusted the K konstans.. But turned it back on when driving trying to adjust it not be overflooded when I touched the throttle.. Why do you 0 all the cel...

Hi! I recently started doing this myself and I'm just trying to get the car running safe and good enough to pass the MOT on monday.. It's a 200sx s14a -98.. I have a gt2871r .86 turbo and the z32 AFM and currently I'm testing my modded stock injectors which now flow around 880cc.. They might be the ...

So it seems =) Thanks anyway though...

Now it's time to get back to battle the next problem.. Massive overfueling haha....

Thank you for yourt time but problem is solved.. Talked to Pete through emails and he looked at the bin and saw a lot of blank values and one of them were the Temperature Conversion table..

A very long story how this happened but that's how it ended

Thanks....

Hi! I'm really desperate for some help here.. I've done all I can think of to solve this problem but now I'm stuck.. Any idea would be helpful I can't tune my car with NIStune as the engine coolant temp sais 205° at all times... I first thought it was the sensor so got a new one which of course was ...
