Re: USB pulled during bin verify-did I blow up my QH?

That's surprising that BOTH HEGOs would go bad at the same time. Either something happened to both of them (both exposed to leaded gas or some HEGO-damaging chemical while in storage), or the problem that affected the first ones is a common problem that simply does affect both at the same time (i.e....

Re: USB pulled during bin verify-did I blow up my QH?

I can't say I've ever had a problem with a QH not responding after disconnecting the USB. However I can't say I've ever done so during a tune-write. But I can imagine if I had done so, the state of the QH MIGHT be in an unknown state. What I would not expect is that the QH is completely non-responsi...

Re: emissions tune: high CO2/NO everything else ok

My guess is your thermactor (smog pump) is also not functional. Back when CATs weren't as effective as they are today at scavenging CO and O2, tunes were setup to bias-rich during Closed Loop conditions to avoid NOx as much as possible and give the CATs CO to digest the NOx that was produced. And to...

Re: emissions tune: high CO2/NO everything else ok

Increased NOx is caused by: Lean conditions High timing If you've got excessively retarded timing to avoid this, then I'd say the problem was you were running lean. This is things that can be dealt with in the tune. However the other thing that will cover for slight problems in a tune are "new" CATs...

Re: Odd fuel imbalance (bank to bank) at 1600-1900rpm

I'm not sure I've heard of this, specifically. But it's usually not tune-related when you have 1 bank doing one thing and the other bank doing something different. That's almost always a physical issue, particularly given these old tunes don't have the concept of letting you program one bank to be c...

Re: Trouble data logging wideband through DPFE

Re: Site upgrade and fixes, Saturday July 25th, 2020 12:00AM Central

Saturday morning had a lot of spam. When spam does come in, I block the IP range it came from as well as change the users pw so they can't easily reuse the account. But Saturday, it was coming in faster than I could do all that.

Seems fine now, so I guess you got the anti spam catcher back in place.

Re: 4.6 2v how to get some crackle on decel

Usually its caused by rich decel AFRs. I don't know if messing with the timing will have much to do with it or not. If it did, I would expect retarded values to be better than advanced values.

Re: Picked up another quarterhorse, can't datalog with it though.

The only thing I can think of is you do have to choose the tune type in the hardware setup (single bank, 2-bank, or 4-bank). And you also have to select payloads to datalog. Then finally write the tune. Since some of the payload items require patch-code in your tune to work, you should always write ...

It's the stock Ranger sending unit. I don't know how similar they are to Mustang's sending unit. I do know I cannot let the fuel level get below 1/4.

It does crank, but it has trouble cranking. This obviously isn't an issue ...

Re: What would cause spark to not advance during low load cruise

I think ISCLPD needs to be upped when you upped NUBASE.

If you've got a very large TPS installed, then I guess it's possible DELTA needs to be lowered ...

Re: What would cause spark to not advance during low load cruise

I'm going to guess that the tune is wrongfully interpreting light-cruise as idle and thus it's using the idle spark functions instead of the spark table(s). It could also be a faulty TPS not sending a clean signal to the EEC to let it know that you are at cruising loads? It might help to post your t...

Re: Hot Start and Restart Problems

I'd say if it cranks fine at lower temps, leave them alone and up the PWs at higher temps. Those 1.x values, for sure, need to be doubled...if not set equal to the example function you posted. My gut feeling is setting them to something around 2.2 will have the problem fixed.

That's a very unique problem. But it seems clear the QH isn't getting sufficient/reliable power when not connected via USB. So I agree, this is most likely a connection issue with your QH and the EEC's edge-connector.
