Re: 1996 Bronco Auto to Manual Swap and Tune

In the GUFx stuff, there's a parameter called DASMIN, I think, that holds ISC flow higher while the speed sensor is showing speed. I believe you can lower that to get more engine braking...or you can activate Decel Fuel Shut Off (DSFO) to turn the injectors off while at speed, in drive, and Closed T...

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

This is where you need to update the tune to be aware of what the flowrate of your replacement injectors are. If the tune still thinks what is installed is 14lb (or whatever the stock size is), then the result is going to be WAY too much fuel. Put the new fuel injector slope/breakpoint/offset values...

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

I've never heard of that procedure for head bolts before. But if I had to guess, that sounds like how you would deal with the TTY bolts. You twist them a certain amount, and expect them to twist (i.e. yield) as part of your last 90 degree turn. As for the water pump bolt, don't be surprised if the p...

The bank selection is nothing more than overcoming the 64k limitation of the 16-bit processor. As such, if there are 4 banks, then that would mean you essentially have 18-bit addresses, where the most-significant 2 bits are the bank addresses. The processor has to work with banks.

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

I know with the V8s, Ford moved to using Torque-To-Yield (TTY) head bolts. I believe they aide in the quick manufacture of engines as well as having a readily repeatable clamping force. However they are not reusable. When attempted, they will yield more readily and give less of a clamping force, or ...

The EEC is not capable of reading boost. Incorrect. The Escort Cosworth EEC-IV reads boost from its frequency type MAP sensor.

Tuned correctly, the EEC can control large injectors just fine, to a point. I have 31s in my 90, and 60s in my turbo 90. Both idled and drove like stock. Agreed. You just need to satisfy the engine. Any extra is not going to hurt unless you go to excess. I've heard numerous people say they've had n...

Re: Dialing in wot fuel

Running the log through EA will illustrate what the injector behavior is doing. It's possible your low slope is too high. Or it could be that you just need to increase Accel/Transient enrichment. It just depends on how quickly you transfer to rich form a lean WOT tip-in.

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

That's a reasonable boost level. Most any stock engine should be able to handle 5-6 PSI without worrying about overloading connecting rods. Obviously 7 PSI on a stock 3.0L is not going to result in the same increase in output as 7 PSI on a larger V8. But it'll still be an impressive performance upgr...
