Re: ROM1 address

I'll hold off on updating the defs until somene can confirm GUF1 ROM2 address and GUFA ROM1 & ROM2 addresses.

I'm assuming GUFB is correct since it's the more popular of the GUFx trio and nobody's complained about it.

Re: ROM1 address

This must have never worked for the BE GUF1 strat. I'm curious as to what data it was corrupting! It probably makes sense that ROM2 is also wrong. Do you know what its offset is? My guess is it's 2-bytes away making it 0x7828. I'll see if I can get that updated. What's GUFA's offsets for these? I'll...

Re: ROM1 address

0x786a is what's in the open source GUF1 def. If that's wrong, it's been wrong for a long time.

I didn't check the latest TunerPro def.

Re: Tuning a turbo'd 2001 3.0L Ranger with BE and QH

The first thing you need to find out is if the stock MAF is going to be enough. I don't know anything about the 3.0L stock MAF, but my guess is it'll max out fairly quickly and 7 PSI might be enough to do that. While talking about the MAF, is the MAF in a draw-thru (MAF before the turbo) or blow-thr...

Re: Making sure my understanding of STFT is right.

If you are correct that this is forced Closed Loop, then the Base Fuel tables are irrelevant. Those are Open Loop tables. Closed Loop has an implicit target of 1.00 lambda all the time. You can veer slightly from that, on average, by altering HEGO Bias values. But Closed Loop wants to see HEGOs swit...

Re: Making sure my understanding of STFT is right.

It depends. At its most basic, LAMBSE is the value that the EEC believes should be the actual AFR. Now in practice, how you think of LAMBSE changes based on whether the EEC is in Open Loop or Closed Loop fueling mode. When in Open Loop, LAMBSE is thought of as the commanded AFR. This IS the lambda t...

Re: What would cause fuel pump to prime with key off?

Agreed. The most likely cause is a bad relay. But lets explore other possibilities that aren't as likely... With a stock wiring configuration and no mechanical/physical problems, the EEC has to turn the fuel pump relay ON for the relay to power the pump. This is a safety feature. There's also usuall...

Re: fuel pump prime time

On the old GUFx strats, a hack was added to the def files to effectively let you adjust this. However it was not an official editable parameter. It was evidently hard-coded to be 1 second. However since we are modifying data in-place in tunes when using a tool like BE or TunerPro, it doesn't really ...

At one point, I thought BE would let you open encrypted definitions and tunes in a view-only mode so you could confirm all the things you want are present in a def before you bought it. If that's there, then maybe you could open your tune in a pay-for def like Adam's (POPSRACING) CRAJ0. I don't reca...

On my setup, one thing I did to avoid lean tip-ins was "bake in" rich-on-tipin into my tune. What I did was purposely set things up so that LAMBSEs settled in down in the mid .90s while at idle. During cruise, the tune is setup to hit targets with LAMBSEs closer to 1.0 (preferably without KAMRFs). A...

Is there any chance you advanced or retarded the cam when installing the timing kit? I could see that affecting low RPM/Load conditions like idle.

In the older GUFx stuff, the I/O offering wasn't that dense. There was only the engine and peripheral engine-related sensors and controls to keep coordinated. As a result, the header that goes to the EEC is only 3 rows of 60 pins. As more complex engine controls, transmissions, and other system inte...

Re: WB stoich, but HEGOs showing rich

Comparing your tune to mine, the only culprit I see is maybe FN320A. Put load numbers in there above 50 for the Load. Your tune has 0.

Other than that, I can't find anything else related to Closed Loop controls that's enough different than mine to explain you being stuck in OL.
