Re: Changing K vs injection pulsewidth

I you knew how much air (in weight) went through the AFM at what voltage you could better estimate injection times/AFR.
But I guess that data is not available...

Re: Reducing K while idle, no effect?

Flex fuel would be interesting, but I've never seen any gas station providing it .. otherwise I'd be more tempted.

My mate just blew his engine with launch control on a LinkG4 ECU.
The oil pump didn't like the stop and go @ higher rpm and broke, the whole engine went kaput.

Re: Reducing K while idle, no effect?

OK, thanks ... interesting. Well my MAF (Q45) goes up to 4.99V in the logs at full boost that is, so I do use the full scale. I'm not sure that the feature pack would be right for me, I'm not interested in launch control and flex fuel would be nice but here in the UK E85 is rare. I've been honing my...

Re: Changing K vs injection pulsewidth

Hmmm ..

I don't have TIM, so as far as I remember the procedure was to adjust K till A/F ratios are in line with what the wideband shows?

Re: Reducing K while idle, no effect?

I reduced TPmin by 1 (from 8 to 7) allowing me to reduce K. Consequently I could lean out idle mixture by reducing K (I was idling at 11.9ish) but for some reason the car didn't like the leaner mixture and started to miss beats as soon as I moved leaner than 12.2. I don't know why that is, my inject...

Re: Changing K vs injection pulsewidth

Thanks for the explanation,

Interestingly the values in the pulsewidth table are very close to actual values I get from the logs.

How would one have to tune without an AFR table?

Changing K vs injection pulsewidth

Out of interest:
When I change K which represents the injector size, why doesn't the Estimated Pulsewidth in NT change?

Re: Reducing K while idle, no effect?

That's what I meant :) On that note it might be worthwhile to put this into the notes pertaining to the injector resizing or MAF change procedures. When you install bigger injectors (resulting in lower K) you might get a richer idle due to TPMin. I will report back if it worked out for me, 11.9 is n...

Re: Reducing K while idle, no effect?

Hi Matt,

Thanks for that.

I basically wanted to calculate what my TP would be with K lowered from (currently) 190 to 170 (the result is 7.9 down from 8.8 )

So TPMin does lock in the K and MAF values then?

Re: NT 1.2.76 MAF % table values displayed incorrectly

The 'bug' is now gone .. I deleted my old ROM_PACK folder and reinstalled it
I also had two files in there version.txt fp_version.txt

NT 1.2.76 MAF % table values displayed incorrectly

The MAF Table % values seems to be displayed wrong.

Re: Reducing K while idle, no effect?

I'm running AFR 11.9, I sit a lot in traffic and would like to run somewhat leaner So let's do the calculation ..at idle: 1 Volt MAF (raw lookup 715) 750 RPM K=190 How is that calculated please? I get 181.13dec That's an 8 bit number ... so I guess I did something wrong? My TP Min is set to 8, here'...

Re: NT shows feature pack gauges on non fp board

I thought there haven been issues with the Z32 ECU and the FP, at least last time I checked.
Has this been resolved?

But back to the issue .. it's a bug then?

Have you seen my other post ...? :)
