will15 Posted February 9, 2022 Share Posted February 9, 2022 I know there are threads on this already that go into great detail and get very complex, but is there any tables i can tweak just to riching this thing up at WOT with out having to turn into a math expert. BA n/a with a supercharger, im happy with the injector scaling just need a bit more fuel up top. Cheers. Quote Link to comment Share on other sites More sharing options...
Puffwagon Posted February 9, 2022 Share Posted February 9, 2022 Just add it to the bottom line of the base table and adjust timing as needed. If you want you can add it to the sd table, in which case you can just highlight every cell from top to bottom at the rpm ranges you want to richen up, and lower the number by 5 or 10%.

Puffwagon Posted February 9, 2022 Share Posted February 9, 2022 Make sure you aren't running out of fuel pressure before you go chasing the tune. 1 Quote Link to comment Share on other sites More sharing options...

Puffwagon Posted February 9, 2022 Share Posted February 9, 2022 Yerp I've got a second sense when my fuel pressure goes low, it's happened so many times before. It's always a weird bit when it comes on boost then it runs out up top. Quote Link to comment Share on other sites More sharing options...

It’s got plenty of fuel I can scale the injector for what I want but then it’s super rich cruise and mid, I tried a couple sd tables but they don’t work over 4000rpm I think that’s due to them being for the intake runner being closed after 3800rpm, what tables are you talking about?

Puffwagon Posted February 9, 2022 Share Posted February 9, 2022 auF0061 is "slope of MAP per AIRCHARGE BF", this is the one you want to change. Here is the write up of how it all works. Quote Link to comment Share on other sites More sharing options...
Puffwagon Posted February 9, 2022 Share Posted February 9, 2022 But yeah easiest way is to just fudge the base fuel table. It doesn't matter if the table says 0.7 λ and the wideband says 0.8 λ. Quote Link to comment Share on other sites More sharing options...

Roland@pcmtec Posted February 9, 2022 Share Posted February 9, 2022 Put 0.5 in your base fuel table. If it doesn't get richer you have a fuel pump issue. Quote Link to comment Share on other sites More sharing options...

hjtrbo Posted February 10, 2022 Share Posted February 10, 2022 Just putting it out there. If you have to "rape" the base fuel table to get fuelling in line then also the torque model will be out. Best to spend extra and buy DW or ID injectors with good data. Not a big deal I suppose if manual, but auto will need tweaks to get torque management / line & shift pressures back into line.

As far as I know the only thing that is affected by the base fuel table is the ignition timing due to spark lambda correction. What transmission tables and torque tables are affected by changing the base fuel table? Quote Link to comment Share on other sites More sharing options...

Roland@pcmtec Posted February 10, 2022 Share Posted February 10, 2022 He is saying if you have to modify the base fuel table to say 0.5 lambda and you have 0.8 measured at the tail pipe then your SD is most likely out. If your SD is out then your load is lower than it should be and hence you'll be getting less torque reduction and less trans pressure than you should.

I really am poor at writing things in a way that gets across what I'm trying to mean. I'm sorry everyone. Please put up with me. It happened in another thread I wrote in the other day too. Thanks Rolls, sums it up nicely. 2 Quote Link to comment Share on other sites More sharing options...

hjtrbo Posted February 11, 2022 Share Posted February 11, 2022 I see, you got that intake manifold runner switch. Valve closes at >3,900rpm All I can see is... MAP at Zero Airmass IMRC Open auF0057 MAP at Zero Airmass IMRC Closed auF16456 Slope of MAP per AIRCHARGE IMRC Open auF0060 Slope of MAP per AIRCHARGE IMRC Closed auF1911 Like I said, never mucked around with a N/A anything before. If manual, just do what Puff said and add it to the base fuel. If auto, can still do as Puff said but just keep an eye on data logged torque to make sure it looks like plausible. Generally at WOT, rear wheel torque plus 130N gets you close. Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted February 11, 2022 Share Posted February 11, 2022 If you are still running the IMRC you should remove it like on a turbo as that will cause you grief. Quote Link to comment Share on other sites More sharing options...
