Re: BZZRPM seems to have no effect (GUFB)

This is an update needed to the def file? I'll try to remember to get that incorporated sometime this week. The GUFx defs hadn't been updated in quite some time, so it'll be nice to finally get v99 out into the wild.

Re: Power drop over 3800-4000

Pulling the coil wire off the center of the dizzy and watching it spark to ground using a nail or some other piece of metal is a good technique for determining spark strength. There should be no question as to whether the spark is "healthy" or not. If you have an ignition box, the spark should be ab...

Re: Power drop over 3800-4000

It's possible there's a problem in your tune. With tables or functions misconfigured to allow over-runs of the bounds of the function or table, you can run into issues like this. Being it is happening sharply as you approach 4000 RPMs, I'm thinking it's quite possible you've created a problem in the...

Re: WAY1 - Where Should the O2 Sensor Go?

...the original O2 sensor was in a crossover right after the exhaust manifolds... That's typical of single bank applications to allow the sensor to see the exhaust of all cylinders.

Re: WAY1 - Where Should the O2 Sensor Go?

If you already have long tubes, then as close to a collector as possible is best. I don't know whether DS or PS makes more sense. On my engine, Bank1 is consistently richer. But I don't think that is universal. The stock Explorer 302 I had originally in the truck had banks pretty perfectly matched. ...

The main thing I see you doing differently is with the cmpw. Instead of comparing a pointed-to-value to zero, you compare a local register to zero, avoiding the pointer value lookup time.

I would be curious to know what your tps voltage is at idle. That'd be an excellent thing to check particularly given he had to run the screw in so far. Although as of his last post, it sounds like he got the screw out further and got a stable idle at lower RPMs. So his TPS hopefully is back under ...

Re: BZZRPM seems to have no effect (GUFB)

According to the GUFB doc, it's a buzz-up RPM adder that's only in effect for the BZZTM time period (usually 3 seconds) after startup. I don't recall that I've ever used that scalar or even attempted to. Although looking at my tune, I see that my BZZTM is set to 5 (stock for both A9L & X3Z is 10). I...

Ok. Hunting, surging, or general idle instability can be caused by either fuel or spark. It sounds like you've eliminated both. So that leaves...the tune.

Initially I was thinking ~1.4v MAFv was erroneous. But then you described...

Re: Why auto disassembly is tough

Ahh, the enable/disable of interrupts is being "managed" implicitly by virtue of the restoration of PSW. That makes sense now that you say it. But due to my lack of familiarity with the PSW reg, it didn't even occur to me that the Enable/Disable bit lived there.

Thanks for the clarification.
