Is there anything that will decrease the degree of MFI response to input at idle?

Using some agressive cams, everything pinned down except idle, it overcompensates going way too lean to missfire, then over rich in a vicious osccillating nightmare. Both open and closed loop. In closed loop for 1v -0.1v NBO2, the psice of crap ecu responds with 1.4 - 2.4 IDC respectively. If there is just a way to keep the IDC result in a 1.6 - 1.8 IDC window of operation for the respective NBO2 signal my idle would be good to go. Cruise is smooth.

Is there such a hacked table available for nonpatched rom (96420007)?

 

You can disable the NB02 at idle by changing the open loop load to 10 at the idle rpm.

If you can figure out what Maf HZ the car bounces at during idle you could clamp it down with a combo of scaling and smoothing.

 

So your saying make one cell above and below target est MAF scaling the same, then smoothing it to a neutral value?

 

Exactly what i'm saying. You can use it like a sort of cap to the value to prevent it from oscillating.

 

Thanks.

Give it another attempt, did something similar but Must not have nailed the HZ value.

Idling S3/S2 cams with MAF, no IAC, in closed loop might be hopeless. Cruise is dead on and WOT makes it worth the time almost trying to get the idle

 

You might want to switch over to speed density if it becomes too much a hassle. Or at the very least ramp up that idle speed to something higher.

 

+1 on the MAF Hz as you have to ensure you are not hovering on the MAF Hz crossover from low and mid. If this is the case, I recommend raising the crossover point slightly.

 

Bingo, would this "crossover" be a table in available in a non-patched rom? Would it be called the 2D "MAF Filter" table with a hi/lo value?

 

This is the what the table looks like in my 88590015 rom. I searched briefly but didn't find it for your rom, but if you dig a bit deeper than I did you may be able to find it.

 

Yep...that is the one.

 

roadspike, you have the address to the LT trim for the 0008 or 0007, or did you convert prior to the table?

 

I moved to the 94170015 rom for the reason it was better defined.

I could probably find it though if you really need it.

In all honesty your better off moving to a v7 rom to get all the tuning tricks anyways.

 

Yeah....the v7 rom and XML are wonderful. Everything you need and more.

 

time for v7 then, I think I have one of his first patchs from 2007

my rom is a 20008/20007 dynoflash mutant so that means I might have to jump to 20011 before I fully convert, right?

I might also be covered for donation as well since I was so happy from 07/08 for my original patch

 

Its not like a windows computer you don't have to "upgrade" in order just flash and go.
