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 ...

I think your question was a bit too generic and broad. If you have a specific question, usually people are far more willing to help.

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. The 255lph pump will pull air if I take a tight turn or slam on brakes and the fuel level is low. So I've just learned to refuel when the needle gets ...

Have you tried opening the gas cap to see if there is any built up pressure when you experience this issue? Could be vapor lock. Is your fuel pump hanger the same as a stock fox body Mustang hanger?

This past weekend, I drove the truck down to South Ga (from Atlanta area) and while the truck cranks fine hot when it's only run for 20-30 minutes, if it runs for longer than an hour, it does seem to have trouble re-cranking. 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. But I don't think this would cause what you are seeing with idle spark persisting longer than you'd like on Throttle Positions near Closed Throttle. 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: Strategy Code for 1992 F150

There may be a definition file to support this strategy.

How opposed are you to replacing the EEC, plumbing in a MAF, and minor rewir...

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.

Re: CDAN4 PIP's and Displacement

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.

Re: 02sensor delete in a drag only car

It doesn't really matter whether you disable them or not if you force Open Loop. Only Closed Loop fueling is going to "look" at them during normal runtime.

KOER tests might would still care, but my guess is a dedicated drag car isn't going to be doing a lot of KOER tests.

Re: Scaling a 39 point MAF transfer to BE 30 point?

You have to selectively exclude points in the 39 curve to get it down to 30. My recommendation would be to remove every other point at the top-end of the curve. However now that you have it running, find out what the engine maxes the MAF out at. If your highest-possible MAFv voltages with your engin...

Re: Help with understanding fueling at different RPM's but same VMAF

In order for the injector slope/bp calcs to mean much, you need a relatively long and varied datalog...that is a datalog that includes as much different RPM/Loads as possible. So stable cruising at all speeds that you'd cruise (i.e. 40-75MPH)...meaning you need to time at each speed to capture not j...

Re: Help with understanding fueling at different RPM's but same VMAF

The problem isn't voltage. The problem is that this is ADDING fuel regardless of RPM/Load condition. The theory behind this setting is that regardless of PW, there's a certain amount of time that passes from when voltage is applied to the injector and when it starts flowing. That time is based on vo...
